Unrooting Your Evo 4G LTE
Ok so you want to unroot your phone. If it is to take your phone in to get it serviced from Sprint, then let me start by saying that Sprint has changed their policy on rooted phones. It is something that they have not really advertised nor will they mention it. As long as your issue is not software related caused by rooting or flashing errors and it is hardware related then you should be fine.
Here is a story from a developer who put the new policy to the test:
Sprint Policy Put to the Test
Before proceeding i must give credit where credit is due: so thanx goes to Regaw, viperboy, and captain throwback. You guys rock and do amazing things.
Disclaimer:
I nor AF are NOT responsible for you blowing your phone up. I am just a guide showing you the way. If you stray from the path, that is not my fault. Only you can prevent forest fires
I will go into detail on how to get your phone setup so that it can be serviced without any issues including how to unroot the phone if that is what you wish.
so here is what you can do:
1. Flash a stock rom
2. Re-locking and running a RUU
3. RegawMOD Bootloader Customizer
4. Unroot using RegawMOD S-ON Writer Utility
1. Flashing a Stock(rooted) Rom[S-ON/S-OFF ONLY]
Ok so the easiest way to take your phone in is to flash the stock rooted rom. This will not remove the watermark, however.
Here is what you do:
1. You will need to download this rom:[ROM][OFFICIAL][12/18]Stock Rooted 3.15.651.16 Odex/Deodex.
2. Next transfer the file over to the sd card.
3. Make a nandroid backup
4. Wipe dalvik cache, cache, factory reset, and system
5. Flash the rom
If you have not flashed a rom before then please go here:http://androidforums.com/evo-4g-lte...ide-lazypanda-racun-unlocked.html#post4851453. Skip to the second post for more details on how to flash a rom.

Ok not sure if you want to do this or not as it will not hide the watermark, when you do this. This method will re-lock the bootloader. However, it will say at the top of the bootloader "re-locked" and that is a dead giveaway that it was rooted at one point(again, not that it matters to Sprint).
Anyways if you want to continue on then here is what you will need to do:
First off let me explain on what a ruu is. RUU stands for rom update utility. It is how we can update the phone and is similar to taking an OTA. They can be found in two forms a PJ75IMG file or in a ruu.exe file. Both files will need a locked or re-locked bootloader in order for it to work.
Also since these files update the phone, you have to make sure that you use the right file or you will get the "hboot version is older"(something to that effect). You can go here: AndroidFiles RUU find your radio version and download it.
OK ready?

Re-locking the Bootloader
You will need to use the same folder that you used to unlock the bootloader. But if you do not have the files anymore you can download these files and put it in a folder(i call it android, but you can name it whatever you want):
1. On the phone boot it into the bootloader and then select fastboot
2. On you pc open the command window from the folder
3. Enter this command:
4. Proceed to running the ruu, if your bootloader says "re-locked"
Running the RUU
1. Download the correct RUU file that matches your radio
2. Connect your phone to the pc via USB cable
3. On your phone, make sure that you have:
Check to see if you have a stock rom, if so then congrats!!!!!
You will need to use the same folder that you used to unlock the bootloader. But if you do not have the files anymore you can download these files and put it in a folder(i call it android, but you can name it whatever you want):
- adb.exe
- fastboot.exe
- AdbWinApi.dll
- HTC Sync 3.0.5551(you only need this if you do not have it already)
1. On the phone boot it into the bootloader and then select fastboot
2. On you pc open the command window from the folder
3. Enter this command:
Code:
fastboot oem relockRunning the RUU
1. Download the correct RUU file that matches your radio
2. Connect your phone to the pc via USB cable
3. On your phone, make sure that you have:
- HTC Sync installed
- USB debugging turned on
- Set the phone to charge only
Check to see if you have a stock rom, if so then congrats!!!!!
This utility will give you the ability to change the watermark on your bootloader to whatever you want it to be. Meaning instead of unlocked you can make it so it says locked. This will also remove the watermark that is also found in the splashscreen.
Here is the original thread: [UTILITY | S-OFF] RegawMOD Bootloader Customizer 3.1.1 | Updated 07.04.12
You should be on a stock rom, however, as this will not change anything but how the bootloader will look. This will not affect your root status.

If you have s-off and want to change it back to s-on then this will now work with the latest hboots now.

Rather then go into specifics on how to do this, i will go into the basics. For more details, please go to regaw's thread.
RegawMOD S-ON Writer Utility is basically two steps after you get everything setup as described in the guide:
1. Run a ruu or PJ75IMG file to get you back to stock
2. Run the RegawMOD S-ON Writer Utility
now the ruu and PJ75IMG files are older you will need to use these files:
1. For all of the current ruu's go to Unlimited.IO. the latest ruu's are listed there.
2. For PJ75IMG ruu:PJ75IMG_Jewel_firmware_2.13.651.1. This will not work with the latest hboot.
After you run the ruu make sure that you have usb debugging turned on. All you will need to do next is run the RegawMOD S-ON Writer Utility .exe file and follow directions.

Again i just want to re-iterate that most places do not care about being rooted, especially if it is hardware related. If the issue was because of a bad flash then you are on your own.
So rest assured the above methods will be adequate enough to take your phone in with no issues. Which one? That will be up to you.
Now go forth and get your unroot on
