The ultimate "get back to stock" thread.

I've seen a few threads out there that have instructions on how to get back to stock. Well, they're either incomplete, or not very easy/quick. So I'm going to make this thread with the different "stocks" you can go to.

Part 1: rooted/s-off -> 2.1 stock for OTA upgrade
Part 2: rooted/s-off -> 2.2 stock using the OTA RUU

Part 0:

1. Make sure you have ADB working, there are many tutorials around XDA/the internet on how to get it working on your computer.

2. After you've setup ADB, download the fastboot binary and put it in the tools folder with the adb binary, so that you can run the "fastboot" command.

Part 1: 2.1 stock for OTA upgrade

1. Make sure you're rooted with clockworkmod recovery.

1A. If you're s-off, download http://www.fourty.net/~berzerker/stockstuff/unrevoked-forever-son.zip

(NOTE: the unrevoked s-on tool does *not* support the 2.15.00.09.01 radio. If you're running that radio, download this, and flash that PB31IMG.zip in HBOOT before continuing.)

1B. Push that to your SDCard and flash it via clockworkmod recovery.

2. Download these two zip files: http://www.fourty.net/~berzerker/stockstuff/revert.zip and http://www.fourty.net/~berzerker/stockstuff/PB31IMG-77-1.00-2.1.zip

2A. Push PB31IMG-77-1.00-2.1.zip to your SDCard, renaming it to "PB31IMG.zip" (no quotes)(delete any other PB31IMG.zip you might have on there before pushing).

3. Unzip revert.zip to your desktop, reboot into recovery and execute the following commands from your cmd prompt/terminal:


You should see a black screen with a silver HTC logo. Now type:
You should see something like HT056HJ01462 pop up. If that does, you're good.

4. Pull the battery, leave the phone off for about 10 seconds, then put the battery back in. Hold the volume *down* button as you put the battery back in, then press the power button (while still holding the volume down button). You should boot into HBOOT, and it should recognize the PB31IMG.zip. Start the update and go get a drink (it might reboot once or twice, don't worry about it).

(4B: If it keeps booting back into HBOOT, you'll need to apply it a second time, but you will not need to reflash misc, so just apply it again, it should take.)

5. When that's done, reboot, and you're done! You are now at 2.1 stock!

6. If you want to go through the OTA upgrade to 2.2, download this, rename it to update.zip and push it to your sdcard. Then, upgrade manually through recovery using the "apply sdcard:update.zip" option. After you reboot back into Android after that's done, you should be able to upgrade normally to 2.2 using the OTA.

Part 2: 2.2 stock using OTA RUU

1. Make sure you're rooted with clockworkmod recovery.

1A. If you're s-off, download http://www.fourty.net/~berzerker/stockstuff/unrevoked-forever-son.zip

(NOTE: the unrevoked s-on tool does *not* support the 2.15.00.09.01 radio. If you're running that radio, download this, and flash that PB31IMG.zip in HBOOT before continuing.)

1B. Push that to your SDCard and flash it via clockworkmod recovery.

2. Download this zip file: http://www.fourty.net/~berzerker/stockstuff/PB31IMG_3.26.605.1_RUU.zip

3. Push PB31IMG-3.21.605.1_RUU.zip to your SDCard, renaming it to "PB31IMG.zip" (no quotes)(delete any other PB31IMG.zip you might have on there before pushing).

4. Boot into HBOOT, and it should recognize the PB31IMG.zip. Start the update and go get a drink (it might reboot once or twice, don't worry about it).

5. When that's done, reboot and you're at 2.2 stock!

That's it! These steps should bring you back to either 2.1 stock or 2.2 stock for a send-in!

I suggest a sticky as well.

The link for the RUU has a dash instead of an underscore. Here is a corrected link:http://www.fourty.net/~berzerker/stockstuff/PB31IMG_3.21.605.1_RUU.zip

I would suggest sticky also. Things have changed a bit over the last few months and these instructions are current. In fact I just followed the exact steps in part 2 a week ago before sending in for a warranty. Did a nandroid before those steps and when I got my replacement all I had to do was run unrevoked 3.2 and restore my nandroid, right back where I left off!
Almost don't even see the need for part 1 though as 2.2 has become stock?

anyways, Thanks!

Some people might want 2.1 for some odd reason, so I thought I'd include instructions (maybe they don't trust the 2.2 RUU or something, or want faster battery charging).

FYI you tried to link something in the word "this" and it didn't work.

Anyway, I put the PB31IMG-3.21.605.1_RUU.zip on my SD card as PB31IMG.zip and it wasn't recognized in HBOOT. I tried flashing the 2.15.00.07.28 radio as PB31IMG.zip and it wasn't recognized either.

Running Skyraider Sense 2.5.2, 2.05.00.06.11 radio. I ran unrevoked forever yesterday but then flashed the s-on file from your step 1A of part 2.

Fixed link in OP.

If you're S-ON, you'll have to flash signed RUU's. Since your radio seems to be older than the 2.2 RUU, you can just flash the 2.2 RUU and it should recognize it.

Will part 2 work if I'm rooted/s-off using the 100% stock 2.2 ROM found in this forum?

Last question, still new to this - can you still get OTA updates after rooting/s-off?

No, you cannot.
