Over there <points>
This is a guide to walk users through installing the Android SDK and using fastboot and ADB. The unlocking and rooting process for HTC devices can be a little daunting. We discovered this with the Evo 3D, so I wrote a similar guide to this one in that section to help ease the confusion. I hope to continue the tradition with this guide in this forum.

So let's get started!

Note: This WILL wipe out your settings, apps, et cetera. Please make any/all necessary backups before proceeding.

Due to popular desire for a simpler guide, I've decided to make a "skinny" version. If you need further explanation, please see post 2 for the "full" guide.

sanman1185 has made a video that he has posted in this thread: http://androidforums.com/evo-v-4g-all-things-root/584703-how-root-video-htc-evo-v.html, click show to see the video:

Step 1) How to install and configure the Android SDK

First, you need to download a lot of software. So here are the download links:

1) HTC Sync

2) TeamWin Recovery Project (TWRP) version 1.1.1 - Recovery - Get the IMG version, not the ZIP version. Rename this file to "recovery.img" if it appears as 'recovery-twrp-shooter-1.1.1.img'. If it appears as 'recovery-twrp-shooter-1.1.1' then just rename it to 'recovery'.

3) The stock ROM. Grab the ODEX version for as near to stock experience as possible.

4) Mini-SDK Then extract Mini SDK to C:\sdk-tools.

Step 2) Move files to where they need to be.

It doesn't really matter where in the SD card you put it. I just recommend you put the Stock ROM + root in a folder named ROMs and the recovery file needs to go in the C:\sdk-tools directory on your computer.

Step 3) Opening the command prompt and getting ready for entering fastboot.

Now, click Start and either open Run, or click in the text box in your start menu. Then type 'cmd'. You get a command prompt. Now we need to go to the Mini SDK folder. If you installed it in the same directory I did, you can copy (or type):

Code:
cd C:\sdk-tools

Step 4) Unlocking with HTC Dev

If you haven't already unlocked your bootloader using HTC DEV Unlock we will do so now.

Step 1) Getting into fastboot.

Go to Settings > Applications > Development and check USB Debugging. You'll need this enabled for the adb reboot command.

Connect your phone to your computer. From now until you're done flashing your ROM, you will not disconnect the USB cable.

Now, in the command prompt, type (or copy and paste):

Code:
adb reboot bootloader
Step 2) Getting the device identifier token and then flashing unlock_code.bin

Type the following command in the command prompt:

Code:
fastboot oem get_identifier_token
A long text boxes will come up. Right mouse button click on the screen and click mark. Then highlight the token from <<<< Identifier Token Start >>>> to <<<<< Identifier Token End >>>>>, like shown:

bootloaderimage.png
infoimage.png


Do not highlight info or bootloader or any extra spaces or text. Once you have done that, right click again and hit copy.

Now go to HTCdev - Unlock Bootloader and fill out the forms and paste the code into the device identifier token box and submit. If you're having trouble with the HTC dev site, please disable any pop up blockers, anti-viruses, and/or firewalls (temporarily). You'll get an email (check your spam folder) with your unlock_code.bin. Once your receive it, transfer that file into your C:\sdk-tools\ folder. Now go back to your command window and type:

Code:
fastboot flash unlocktoken Unlock_code.bin
The unlock token should give you a prompt to accept the unlock code or not on the phone. Push volume up to accept. The phone should now reboot for you (so that you'll be back in Android). If it doesn't you can do it manually by reinserting the battery and then holding Vol down + power. You should now see UNLOCKED displayed at the top. If so, congratulations, you are now unlocked!

Step 5) Let's install then boot into recovery!

Now we need to get back into the bootloader.

To do that, type this in the command prompt:

Code:
adb reboot bootloader
Once in the bootloader (HBOOT) type (or copy):

Code:
fastboot flash recovery recovery.img
This now flashes TWRP 1.1.1 that we downloaded earlier.

Wait for that to finish, then type (or copy/paste):

Code:
fastboot boot recovery.img

Step 6) Before you do anything, it's time to make a backup.

I'd recommend that you backup:

System
Data
Boot
Wimax

Everything else is optional, in my opinion.

Step 7) Flashing the ROM

TWRP 1.1.1 has capacitive buttons that work, so hit the back button. To flash a ROM/Kernel, do the following:

1) Go to Wipe Menu

A) Wipe Cache
B) Wipe Dalvik Cache
OPTIONAL) Wipe Everything (Data Factory Reset) - This is useful if you have problems with flashing certain ROMS. Some ROMs require this before flashing. For the stock ROM, this isn't necessary. But if you're on HBOOT 1.5 and used HTC Dev, you did a factory reset anyways, so it can't hurt.

2) Go back and now go to Install Zip.

A) Choose Zip
B) Go to the folder ROMs/
C) Select the ROM you want to flash (the stock ROM or SU patch for example)
D) If you're flashing another kernel, you would find your kernel and by selecting Choose Zip and finding the kernel file. The kernel must be selected AFTER the ROM is selected, or else the kernel built into the ROM will overwrite the kernel you want to flash.
E) Check 'Reboot After Successful Flash' - this is just a nice feature of TWRP that makes it so you don't have to pay attention to the flashing process.
F) Flash Zips Now

3) Sit back and relax. The flash is going to take 3 or so minutes. Then it'll reboot. The reboot will take 5 minutes or so and will always take 5 minutes or so every time you clear out the cache and dalvik cache. It is normal.

If successful, congradulations! You flashed a recovery, ROM and kernel by using fastboot!

Quick Guide) Flashing another ROM

Let's say you want to flash a new ROM. Here's how to do it:

If you're starting in Android, connect your USB cable. Then click Start and either open Run, or click in the text box in your start menu. Then type 'cmd'. You get a command prompt. Now what you type or copy/paste will depend on your version of Windows and where you installed the Android SDK.

Code:
cd C:\sdk-tools
Then type:

Code:
adb reboot bootloader
When the bootloader appears, type:

Code:
fastboot boot recovery.img
You're now in recovery. Make a backup if you wish, then:

1) Go to Wipe Menu

A) Wipe Cache
B) Wipe Dalvik Cache
OPTIONAL) Wipe Everything (Data Factory Reset) - This is useful if you have problems with flashing certain ROMS. Some ROMs require this before flashing. For the stock ROM, this isn't necessary. But if you're on HBOOT 1.5 and used HTC Dev, you did a factory reset anyways, so it can't hurt.

2) Go back and now go to Install Zip.

A) Choose Zip
B) Go to the folder ROMs/

C) Select the ROM you want to flash. If you chose just to download the SU patch or the stock ROM + Superuser, this is where you would select the file.

D) If you're flashing another kernel, you would find your kernel and by selecting Choose Zip and finding the kernel file. The kernel must be selected AFTER the ROM is selected, or else the kernel built into the ROM will overwrite the kernel you want to flash.
E) Check 'Reboot After Successful Flash' - this is just a nice feature of TWRP that makes it so you don't have to pay attention to the flashing process.
F) Flash Zips Now

3) Sit back and relax. The flash is going to take 3 or so minutes. Then it'll reboot. The reboot will take 5 minutes or so and will always take 5 minutes or so every time you clear out the cache and dalvik cache. It is normal.
If successful, congradulations! Enjoy the new ROM/Kernel!

(Optional) Installing 4EXT - Highly Recommended!

There is a recovery that makes it really easy for HBOOT 1.5 people to flash ROMs and kernels. It's called 4EXT Touch Recovery. If you're familiar with ROM Manager, you'll love this app/recovery. You can control every aspect of your phone's recovery from an app. Best of all, even with S-ON Unlocked, you can flash kernels without using fastboot. Just go to their website to get the free version that comes with a 3 day trial of the full version, or get the full version. After you're done with the trial, I'm sure most of you will want the full version. It makes everything easy. I use it, too, and I'm on HBOOT 1.4 :p

To install, download/install the app (free or paid) and open it. Give it SuperUser permissions and then click through all the pop up dialogs. Push the install button at the top. Indicate if you are S-ON or not (if you had to unlock with HTC, then you click yes). And it installs. And after 5 minutes of running the free version, your trial for the full version starts. So come back in 5 minutes and reload the app (by pushing the back button until you get back to the desktop and relaunch). If you're on the paid version, you can just start using the app immediately.

Now go to recovery and you can do everything you would normally do in recovery, but it's fully automated once you click start after selecting all your options. Including making backups, wiping caches, and installing ROMs. Remember to support the developers if it makes things a lot easier for you!

(Optional) Getting S-OFF - Highly Recommended!

What is S-OFF?

S-OFF means that bootloader security is off. This allows you to flash images to the /boot partition. Simply put: It lets you flash whatever you want without using fastboot or specially enabled recoveries. It makes things much easier to do but it also takes away the security that keeps you from bricking your device. If you do S-OFF (it is recommended), remember to check everything that you're about to flash and make sure it's for the Evo V.

http://androidforums.com/evo-v-4g-all-things-root/558583-s-off-juopunutbear-s-off-beta-release.html - S-OFF while staying on HBOOT 1.5. Requires you do a 'wire trick' to ground out a signal at a certain point. May be easier than temporarily bricking your device.

---------------------------------------------------------------------------------------------

Based off of my Evo 3D root guide found here: http://androidforums.com/evo-3d-all...shing-evo-3d-roms-kernels-using-fastboot.html

Some of the commands in this guide were found here: [GUIDE] HTC Unlock Hboot 1.50 + TWRP Recovery + Root + Flash!! [9.11.11] - xda-developers and http://androidforums.com/evo-3d-all...lash-recovery-image-via-fastboot-sd-card.html. I just sought to make a complete newbies guide version of it.
 
Note: This WILL wipe out your settings, apps, et cetera. Please make any/all necessary backups before proceeding.

Step 1) How to install and configure the Android SDK

First, you need to download a lot of software. So here are the download links:

1) HTC Sync is needed to link your phone to your computer with the proper drivers. On XDA they link the HTC drivers by themselves. These are fine, but I can't find a direct link on the HTC site, so I'm linking HTC Sync.

2) TeamWin Recovery Project (TWRP) version 1.1.1 - Recovery
For the sake of this tutorial, we will be getting the fastboot (called img) version of TWRP 1.1.1. You can replace with CWM, if you have the .img file for it. However, this guide walks users through using TWRP 1.1.1.

3) You will also need either the Superuser Patch file or the stock ROM + Superuser built in, choose below:
Option 1: The stock ROM. Grab the ODEX version for as near to stock experience as possible. It is highly recommended that you use the full stock ROM.

Option 2: Superuser-3.0.7-efghi-signed.zip - SuperUser patch for the stock ROM (I will refer to it as the 'SU patch' from here on out). A smaller download, but some users have problems installing it.
4) Mini-SDK is a multiple platform set of fastboot and ADB so that you do not have to download the full Android SDK. It is easier to use, too. Just download sdk-tools.zip and extract it to your hard drive. I'll assume that most of you are using Windows, and for this tutorial, I'll extract Mini SDK to C:\sdk-tools. But Mini-SDK has Mac and Linux versions included in the zip file, so all are supported here.

Alternatively, if you want to install the full Android SDK, you can do so by following this guide. Ignore that it's in the Evo 3D section, the Android SDK is universal.

Step 2) Picking the recovery, ROM, and kernel you want to use.

First, go into Control Panel for Windows. Go to Folder Options. Go to the View tab. Now uncheck the box that says "Hide extensions for known file types". This will make things so less confusing in the long run. If you know what file extensions are and don't feel the need to do this, fine. Just know that all file names that I will list here will assume that file extensions are shown.

Second, download TWRP and the SU Patch or ROM. You can substitute any ROM for the SU Patch, this process is the same, regardless.

Next, move the ROM/SU Patch to your SD card. You can do this by enabling the phone in Disk Mode or any other method. I recommend you make a subfolder called 'ROMs'. It can be named anything, but I have my ROMs in a folder called 'ROMs' on my SD card, and I'm going to reference everything in that directory.

Now, rename the file 'recovery-twrp-shooter-1.1.1.img' to 'recovery.img'. You don't have to do this, but it's just easier if you do. Place this file in your sdk-tools folder.

NOTE: If you have extensions hidden, the filename will be 'recovery-twrp-shooter-1.1.1'. If this is the case, you just need to rename it to 'recovery'. Or go into Folder Options and make Windows display file extensions.

Step 3) Opening the command prompt and getting ready for entering fastboot.

Now, click Start and either open Run, or click in the text box in your start menu. Then type 'cmd'. You get a command prompt. Now we need to go to the Mini SDK folder. If you installed it in the same directory I did, you can copy (or type):

Code:
cd C:\sdk-tools

Now go back into your command prompt and right click on it. Click paste and then push enter. You should now be in the mini SDK directory. If you have Windows 7, you can go to your mini SDK folder and right click on the folder and click "Open command window here" as an alternative means than copying and pasting (thanks to mteezey for the tip). To check that you are in the right folder, you can type 'fastboot' then enter, you should get this:

Code:
C:\sdk-tools>fastboot
usage: fastboot [ <option> ] <command>

commands:
  update <filename>                        reflash device from update.zip
  flashall                                 flash boot + recovery + system
  flash <partition> [ <filename> ]         write a file to a flash partition
  erase <partition>                        erase a flash partition
  getvar <variable>                        display a bootloader variable
  boot <kernel> [ <ramdisk> ]              download and boot kernel
  flash:raw boot <kernel> [ <ramdisk> ]    create bootimage and flash it
  devices                                  list all connected devices
  continue                                 continue with autoboot
  reboot                                   reboot device normally
  reboot-bootloader                        reboot device into bootloader
  help                                     show this help message

options:
  -w                                       erase userdata and cache
  -s <serial number>                       specify device serial number
  -p <product>                             specify product name
  -c <cmdline>                             override kernel commandline
  -i <vendor id>                           specify a custom USB vendor id
  -b <base_addr>                           specify a custom kernel base address
  -n <page size>                           specify the nand page size. default:
2048

C:\sdk-tools>

Step 4) Unlocking with HTC Dev

If you haven't already unlocked your bootloader using HTC DEV Unlock we will do so now.

For the record: I hate HTCdev. Many users have problems with it. If you have problems with this next section, please send feedback to HTCdev explaining how their process is overly complicated and has issues. But do so politely, please.

Step 1) Getting into fastboot.

First, let's turn off one of HTC's defaulted on features. So let's turn off the very frustratingly named 'Fast Boot' in Settings > Power. No, this is not 'fastboot' in the Android SDK. This is a feature that is like Hibernate in Windows but for HTC devices. I really hate how HTC calls it this, but that's what they decided to call it.

Next, go to Settings > Applications > Development and check USB Debugging. You'll need this enabled for the adb reboot command. Plus a number of rooting apps require it. Give the computer a few minutes to recognize your phone, install drivers, and so on, if it needs to.

Connect your phone to your computer. From now until you're done flashing your ROM, you will not disconnect the USB cable. So don't even think about it!

Quick tip: Do NOT connect to a USB 3.0 port. For some reason, fastboot will not detect your device if you're connected through a USB 3.0 port. If you're unsure if you have a USB 3.0 port, don't worry about it unless your fastboot commands say that they're waiting for device when the device is hooked up.

Now, in the command prompt, type (or copy and paste):

Code:
adb reboot bootloader
You should now be in your bootloader. It should say "FASTBOOT USB" in red highlight. If so, this is good! If not, make sure HBOOT in the menu is highlighted and push the power button. This will change it to FASTBOOT and it'll detect that it's connected to USB and change in a few seconds. Now type (or copy):

Step 2) Getting the device identifier token and then flashing unlock_code.bin

Type the following command in the command prompt:

Code:
fastboot oem get_identifier_token

A long text boxes will come up. Right mouse button click on the screen and click mark. Then highlight the token from <<<< Identifier Token Start >>>> to <<<<< Identifier Token End >>>>>, like shown:

bootloaderimage.png
infoimage.png

Do not highlight info or bootloader or any extra spaces or text. Once you have done that, right click again and hit copy.

Now go to HTCdev - Unlock Bootloader and fill out the forms and paste the code into the device identifier token box and submit. If you're having trouble with the HTC dev site, please disable any pop up blockers, anti-viruses, and/or firewalls (temporarily). You'll get an email (check your spam folder) with your unlock_code.bin. Once your receive it, transfer that file into your C:\sdk-tools\ folder. Now go back to your command window and type:

Code:
fastboot flash unlocktoken Unlock_code.bin

The unlock token should give you a prompt to accept the unlock code or not on the phone. Push volume up to accept. The phone should now reboot for you (so that you'll be back in Android). If it doesn't you can do it manually by reinserting the battery and then holding Vol down + power. You should now see UNLOCKED displayed at the top. If so, congratulations, you are now unlocked!

If you still see "LOCKED" or have any problems:
If it still shows as "LOCKED" or you still have problems flashing the token, you have to flash the RUU. Here is a guide on how to do that: http://androidforums.com/evo-v-4g-a...evo-v-4g-ruu-flashing-guide-unroot-guide.html

After the RUU is completed, try to flash the unlock code again.

Step 5) Let's install then boot into recovery!

Now we need to get back into the bootloader. Here's how to do it, if you don't remember how to do it (and so you don't have to go back to a previous step):
We need to turn off one of HTC's defaulted on features. It is the very frustratingly named 'Fast Boot' in Settings > Power. No, this is not 'fastboot' in the Android SDK. This is a feature that is like Hibernate in Windows but for HTC devices. I really hate how HTC calls it this, but that's what they decided to call it.

Next, go to Settings > Applications > Development and check USB Debugging. You'll need this enabled for the adb reboot command. Plus a number of rooting apps require it. Give the computer a few minutes to recognize your phone, install drivers, and so on, if it needs to.

Connect your phone to your computer. From now until you're done flashing your ROM, you will not disconnect the USB cable. So don't even think about it!

Quick tip: Do NOT connect to a USB 3.0 port. For some reason, fastboot will not detect your device if you're connected through a USB 3.0 port. If you're unsure if you have a USB 3.0 port, don't worry about it unless your fastboot commands say that they're waiting for device when the device is hooked up.

Now, in the command prompt, type (or copy and paste):

Code:
adb reboot bootloader

You should now be in your bootloader. It should say "FASTBOOT USB" in red highlight. If so, this is good! If not, make sure HBOOT in the menu is highlighted and push the power button. This will change it to FASTBOOT and it'll detect that it's connected to USB and change in a few seconds.

Now type (or copy):

Code:
fastboot flash recovery recovery.img

This now flashes TWRP 1.1.1 that we downloaded earlier. A vertical green progress bar will be displayed on the right. If it returns a command like 'file not found'. Make sure you renamed the recovery-twrp-shooter-1.1.1.img to recovery.img. If it still doesn't work, make sure the recovery file is in the C:\sdk-tools\ folder. Can you just change the command to read "fastboot flash recovery recovery-twrp-shooter-1.1.1.img"? Yes, but it makes the next command tougher to type every time you want to flash something. So renaming it once before you flash is easier than typing it every single time you want to access the recovery through fastboot.

Now type (or copy/paste):

Code:
fastboot boot recovery.img

Step 6) Before you do anything, it's time to make a backup.

Now that we have TWRP 1.1.1 installed, we should make a back up. This is done by using the volume keys and pushing power as enter. Now you have a few options. You can back up as much or as little as you want. But I'd recommend that you backup:

System
Data
Boot
Wimax

Everything else is optional, in my opinion.

Step 7) Flashing the ROM

TWRP 1.1.1 has capacitive buttons that work, so hit the back button. To flash a ROM/Kernel, do the following:

1) Go to Wipe Menu

A) Wipe Cache
B) Wipe Dalvik Cache
OPTIONAL) Wipe Everything (Data Factory Reset) - This is useful if you have problems with flashing certain ROMS. Some ROMs require this before flashing. For the stock ROM, this isn't necessary. But if you're on HBOOT 1.5 and used HTC Dev, you did a factory reset anyways, so it can't hurt.

2) Go back and now go to Install Zip.

A) Choose Zip
B) Go to the folder ROMs/
C) Select the ROM you want to flash (the stock ROM or SU patch for example)
D) If you're flashing another kernel, you would find your kernel and by selecting Choose Zip and finding the kernel file. The kernel must be selected AFTER the ROM is selected, or else the kernel built into the ROM will overwrite the kernel you want to flash.
E) Check 'Reboot After Successful Flash' - this is just a nice feature of TWRP that makes it so you don't have to pay attention to the flashing process.
F) Flash Zips Now

3) Sit back and relax. The flash is going to take 3 or so minutes. Then it'll reboot. The reboot will take 5 minutes or so and will always take 5 minutes or so every time you clear out the cache and dalvik cache. It is normal. So let it do it's thing. If 10 minutes goes by, check for bootlooping. Most boot animations have a start animation and then a repeat animation. If you see the start animation a second time in a boot cycle, you may have a bootloop problem. The stock VM boot animation has a chime when it starts booting, if you hear that more than once, you're probably bootlooping. If so, pull out the battery (or push vol up + down + power) then push vol down + power to get into the bootloader. Your USB cable should be connected still, so make sure it shows 'FASTBOOT USB' again. If so, type 'fastboot boot recovery.img' in the command prompt to go back into recovery. Wipe everything again (data, dalvik and cache) and try a reflash.

If successful, congradulations! You flashed a recovery, ROM and kernel by using fastboot!

Quick Guide) Flashing another ROM

Let's say you want to flash a new ROM. Here's how to do it:

If you're starting in Android, connect your USB cable. Then click Start and either open Run, or click in the text box in your start menu. Then type 'cmd'. You get a command prompt. Now what you type or copy/paste will depend on your version of Windows and where you installed the Android SDK.

Code:
cd C:\sdk-tools

Then type:

Code:
adb reboot bootloader

When the bootloader appears, type:

Code:
fastboot boot recovery.img

You're now in recovery. Make a backup if you wish, then:

1) Go to Wipe Menu

A) Wipe Cache
B) Wipe Dalvik Cache
OPTIONAL) Wipe Everything (Data Factory Reset) - This is useful if you have problems with flashing certain ROMS. Some ROMs require this before flashing. For the stock ROM, this isn't necessary. But if you're on HBOOT 1.5 and used HTC Dev, you did a factory reset anyways, so it can't hurt.

2) Go back and now go to Install Zip.

A) Choose Zip
B) Go to the folder ROMs/

C) Select the ROM you want to flash. If you chose just to download the SU patch or the stock ROM + Superuser, this is where you would select the file.

D) If you're flashing another kernel, you would find your kernel and by selecting Choose Zip and finding the kernel file. The kernel must be selected AFTER the ROM is selected, or else the kernel built into the ROM will overwrite the kernel you want to flash.
E) Check 'Reboot After Successful Flash' - this is just a nice feature of TWRP that makes it so you don't have to pay attention to the flashing process.
F) Flash Zips Now

3) Sit back and relax. The flash is going to take 3 or so minutes. Then it'll reboot. The reboot will take 5 minutes or so and will always take 5 minutes or so every time you clear out the cache and dalvik cache. It is normal. So let it do it's thing. If 10 minutes goes by, check for bootlooping. Every boot animation has a start animation and then a repeat animation. If you see the start animation a second time in a boot cycle, you may have a bootloop problem. If so, pull out the battery (or push vol up + down + power) then push vol down + power to get into the bootloader. Your USB cable should be connected still, so make sure it shows 'FASTBOOT USB' again. If so, type 'fastboot boot recovery.img' in the command prompt to go back into recovery. Wipe everything again (data, dalvik and cache) and try a reflash.

If successful, congradulations! Enjoy the new ROM/Kernel!

(Optional) Installing 4EXT - Highly Recommended!

There is a recovery that makes it really easy for HBOOT 1.5 people to flash ROMs and kernels. It's called 4EXT Touch Recovery. If you're familiar with ROM Manager, you'll love this app/recovery. You can control every aspect of your phone's recovery from an app. Best of all, even with S-ON Unlocked, you can flash kernels without using fastboot. Just go to their website to get the free version that comes with a 3 day trial of the full version, or get the full version. After you're done with the trial, I'm sure most of you will want the full version. It makes everything easy. I use it, too, and I'm on HBOOT 1.4 :p

To install, download/install the app (free or paid) and open it. Give it SuperUser permissions and then click through all the pop up dialogs. Push the install button at the top. Indicate if you are S-ON or not (if you had to unlock with HTC, then you click yes). And it installs. And after 5 minutes of running the free version, your trial for the full version starts. So come back in 5 minutes and reload the app (by pushing the back button until you get back to the desktop and relaunch). If you're on the paid version, you can just start using the app immediately.

Now go to recovery and you can do everything you would normally do in recovery, but it's fully automated once you click start after selecting all your options. Including making backups, wiping caches, and installing ROMs. Remember to support the developers if it makes things a lot easier for you!

(Optional) Getting S-OFF - Highly Recommended!
What is S-OFF?

S-OFF means that bootloader security is off. This allows you to flash images to the /boot partition. Simply put: It lets you flash whatever you want without using fastboot or specially enabled recoveries. It makes things much easier to do but it also takes away the security that keeps you from bricking your device. If you do S-OFF (it is recommended), remember to check everything that you're about to flash and make sure it's for the Evo V.

http://androidforums.com/evo-v-4g-all-things-root/558583-s-off-juopunutbear-s-off-beta-release.html - S-OFF while staying on HBOOT 1.5. Requires you do a 'wire trick' to ground out a signal at a certain point. May be easier than temporarily bricking your device.

Based off of my Evo 3D root guide found here: http://androidforums.com/evo-3d-all...shing-evo-3d-roms-kernels-using-fastboot.html

Some of the commands in this guide were found here: [GUIDE] HTC Unlock Hboot 1.50 + TWRP Recovery + Root + Flash!! [9.11.11] - xda-developers and http://androidforums.com/evo-3d-all...lash-recovery-image-via-fastboot-sd-card.html. I just sought to make a complete newbies guide version of it.

Unless we get s-off, this is the only way possible.

There are some S-OFF methods for the Evo 3D, but I don't know if they will work with the Evo V, so I didn't want to refer to them.

If people want to try, I'd gladly link to them. One requires you to temp brick your phone and downgrade the HBOOT to a version that the Evo V never had. The other requires a little 'wire trick' to short out an input to defeat the security and set S-OFF. But the second method also requires you to be unlocked and rooted through HTC Dev, so it's not like it circumvents it.

Both would be at-your-own-risk, obviously.

I take this statement back. I posted a thread here how to s-off the device. Or you can always just HTC unlock the device

Don't you need to HTC Unlock to get s-off anyway? Or am I just reading the instructions wrong?
In order to use JuopunutBear you must meet the following pre-requisites:

*Be unlocked using the HTCdev bootloader unlock

Yeah you are right. But you don't HAVE to do s-off. HTC unlock unlocks recovery system and boot partitions. Nothing else. So for the casual flasher HTC unlock is sufficient. But for someone that flashes daily HTC unlock isn't the best choice. S-off gives you full control of everything related to your phone. But also makes it easy to brick if you don't know what you are doing/flashing

So, today a friend and I hacked our devices for a lack of a proper term for everything we did. We followed this guide for our Evo V 4Gs. We were able to unlock with zero issue and we both were able to use the S-OFF method jzm posted elsewhere with the wire trick. We had to flash an extra hboot file to make it work, however. Found out how to do it on the IRC channel #htc-evo-3d on freenode. So, once all that was done, we discovered that any Sprint-ready rom for the HTC Evo 3D should work. We're both currently on Swagged Out Non-Sense with no issue. All features of the phone work.

I know you said all features work but specifically does SMS & MMS work because VM handles these different and ROMs meant for other phones on both Sprint & VM (e.g. Samsung Intercept) had problems with SMS & MMS when using a Sprint ROM on VM phones.

SMS works perfectly fine, MMS appears to send but in my test of sending a pic to myself I haven't gotten a text incoming yet

Casual flasher means what exactly?
