Root Quick Guide to the rooted stock 2.3 ROM

[novox77]

This quick guide is intended to explain how to upgrade your phone to the rooted stock 2.3 ROM posted on xda here:

[ROM][STOCK] --- Version 4.22.651.2 --- odexed & deodexed ---

or here:
[ROM][STOCK] 4.24.651.1 - Odexed & De-Odexed


Since the contents of that OP is subject to change, this guide can become outdated without notice.

The list of downloads contain an odexed and de-odexed version of the stock ROM. For a great explanation of the difference, see this article:
What Is Odex And Deodex In Android [Complete Guide]
For the purposes of this guide, if you're not sure which one to get, stick with the odex version. It is closer to stock.


Flashing the ROM
Most of what you'll be doing will be done through recovery. So play around with the menus in the recovery image to see what options are there. Start off by doing a NANDroid backup. Since this is a quick guide, I will assume you know how, or can find out how. Next, wipe dalvik-cache. You don't need to wipe data or cache if you're coming from a rooted stock ROM, even if your kernel is custom. Now you are ready to flash the ROM. The ROM contains the stock OS (w/ superuser) and stock kernel. All of this is done from the recovery image.

When the flashing is done, you can reboot and see if it worked. Take a quick look to see if your data, apps, homescreens are still there. They should be. If you like what you see, you can stop here. Having the most updated radios is not essential for upgrading to this ROM. If you want to flash radios, keep reading.

Flashing the Radios
Note that the OP in the xda thread says to flash the radios via HBOOT instead of recovery. That's because the provided radio file is in the PC36IMG.zip format. Note the actual file name is PC36IMG-Radio_2.15.00.05.02_WiMAX_R4623-EVO27242_PRI_2.15_003.zip. Rename this to PC36IMG.zip, and the bootloader will find it. Note that Windows may be set to hide extensions; if so, you'll want to rename it to PC36IMG

So all you do is download this file and stick it in the root (top) folder of your SD card. Then power off your phone and boot into the bootloader (from phone off, hold power + vol_down). HBOOT will auto-scan your SD card and find that file and prompt you whether to install its contents. Say yes, and it will do its thing. When done, reboot, and you should have the updated radios.

Done.

Never accept an OTA if you are rooted. One thing you can do to help prevent this from accidentally happening is by disabling the OTA update check:

Menu > Settings > System Updates > HTC software update > Scheduled check (uncheck this box) "Go online and check for updates according to schedule from server"

Always do a NANDroid backup before you flash, and you'll always have a way to recover from an unexpected problem.

Good Luck!

But my main problem is I can't get the phone to start in hBoot.


***EDIT***

It worked after a battery pull...that was weird.

Under the Application settings in the new ROM there is the Fastboot option. If you turn this off and then restart you can get to hBoot with out having to pull the battery.

If you are using Amon Ra v2.3, you can the radios via recovery. You do not need to in hboot.

Amon Ra

Download radio, wimax, pri zip
Boot to recovery
Flash radio.......
Then reboot
Green arrow pointing down on phone
Then reboot again


EDIT: I used Calkulin's radio...zip

I like Calkulin's packages myself - link here - [ Radios ][ 6-3 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions - xda-developers

I plan on doing the same via CWM.

Edit - for those using the hboot radio package - once you've completed that, remove the PC36IMG.zip from your SD card (or at least it's root) - PITA to deal with it once it's installed.

A tip from the original PC36IMG.zip rooting days.

Do need this Kernel - HTC#1 May04 w/ RAMDisk (Stock ROM)?

 

[novox77]

Do need this Kernel - HTC#1 May04 w/ RAMDisk (Stock ROM)?

If you flash the main ROM, it comes with that kernel. But they provided a standalone kernel in case you flashed a custom one and then wanted to go back to stock. Without this, you'd have to reflash the whole ROM again.

Note the actual file name is PC36IMG-Radio_2.15.00.05.02_WiMAX_R4623-EVO27242_PRI_2.15_003.zip. According to xHausx, you don't need to rename this file to PC36IMG.zip. As long as the file contains "PC36IMG" the bootloader will find it.

When I had the file in the SD root directory named as "PC36IMG-Radio_2.15.00.05.02_WiMAX_R4623-EVO27242_PRI_2.15_003" HBoot did not automatically recognize it. I had to go in and rename to PC36IMG.zip for it to automatically recognize and ask if I wanted to install.

Yeah I tested also, needs to be pc36img and that only...

I would have to agree.....otherwise we wouldn't see as many people having issues flashing those files in hboot with an extra .zip on the end of the file name.

true my friend, true

 

[EarlyMon]

BTW - I really wonder if that long PC36IMG name applies to all revs of the bootloader - I'm still running the original one, hadn't heard of that before.

Yeah I had that same thought, haus knows his stuff usually so something gives...does it work on yours as long as its in the name our does it have to be exact?

Exact for me on 2.10...

 

[EarlyMon]

Work and modding all day, some Evo 3D posting. Hoping to do it tomorrow, but will probably use C's zip file and just do it from recovery.

I'd have to check, but I think I'm on 0.79.

I am going to reflash Amon RA(I have a wierd issue with it) and will try and use the name in the download first to see if it works. I am on .93

Cool yeah I'm just curious at this point. I would bet haus is on eng because those guys like the extra options...

did evo 2.3.3 update including radios. restarted hboot so I could make nandroid b/u and it is again asking if I want to start update? Thought I was good. Should I start it again?

It's asking you if you want to start the update again because you forgot to rename the PC36IMG file. If you don't rename it everytime you go into hboot it will try to install it again. I renamed mine NewRadiosGBPC36IMG.zip.zip. This should take care of your problem.

 

[Tapper88]

so, select no on update then go into sd card and rename? TY

 

[cdadams1223]

Yes. Plug your phone into your pc, load up your sd card, find the PC36IMG file and rename it there. Or, you could use a program like ES File Explorer to rename it.

I am an Unrevoked user that was using 2.2 and I'm now happily using 2.3.3 ! Thanks!

Question...and as I type it sounds silly...but I'm gonna ask it for myself and any other not-so-familiar-with-this person who might be wondering the same thing.

I'm familiar with NAND backups...and fortunately/unfortunately restoring them ...and understand the need to make the backups before trying anything fancy.

Now here it is suggested to make a nandroid backup of your phone which, for me and many others, is froyo 2.2. Here's my question/scenario...I make my nandroid backup, then flash this Gingerbread 2.3 and, for whatever reason, have problems or don't like or whatever and want to REVERT BACK to froyo 2.2...

Do I simply backup from my froyo 2.2 nandroid backup and, VOILA, I'm back to my previous stable-state froyo 2.2 phone as if I never attempted to flash the gingerbread 2.3?? Or do I have to flash a stock 2.2 ROM to get back to my froyo 2.2??

Again, forgive the ignorance but like to have some knowledge of not only how to jump in forward but BACKWARDS too if necessary...THANKS!!

 

[scudder]

Can someone comment on the various methods suggested for wiping the phone prior to flashing this gingerbread ROM?? Was wondering what methods people are using, how many times to wipe (I have heard people wiping THREE times and not sure if this is overkill or what??), etc??

The OP link to the XDA forum has a WIPE zip at XDA. In addition, a Good and Evo post mentioning the gingerbread ROM at XDA has a comment that suggests using a method "Vr_superwipe" to wipe the phone and was wondering anyone's success/familiarity with using that suggested method??

You don't have to do anything special in regards to restoring your nandroid backup. Some people say you don't need to wipe prior to restoring a nandroid but I always do. Just wipe everything, cache, etc., and restore your nandroid.

Here's what I do:

1) Wipe all/Format all (whatever it says)
2) Wipe Cache
3) Wipe Dalvik Cache
4) Flash Calkulin's Format All
5) Flash ROM

 

[novox77]

This is my understanding (I may be wrong):

Nandroids are images of the entire partition, including empty space. Which means that when you restore a nandroid, it overwrites the entire partition, leaving nothing behind. The partitions that the NANDroid backs up include the areas you normally wipe: data, cache, and dalvik. Therefore, you shouldn't need to do a wipe before you restore a Nandroid.

When you install a new ROM, you typically only replace /boot (kernel) and /system (OS). Which is why data, cache, and dalvik need to be cleared. A format-all will also wipe /boot and /system, but this part is extraneous, since the new ROM will flash over these partitions, which effectively wipes them anyway.
