Complete guide to unrooting the HTC Slide

If you decide to root the MyTouch Slide and then want to go back to stock for whatever reason (maybe you prefer Sense UI, or T-Mobile eventually comes up with an official update, or you need to send your phone in for warranty), then this is the guide for you.

WARNING: Do this at your own risk! I take no responsibility for any lost data, software/hardware damage or you bricking your phone.

STEP 1: Backup whatever contacts, messages, apps data you want. You should also go into Clockwork Recovery and do a nandroid backup just in case. After you proceed, you will no longer have access to Clockwork.

STEP 2: Download the following file and transfer it to the root of your sdcard:
It should look like this in Windows Explorer:


This is the official stock image (sometimes called the Champion build) that came with the phone when shipped from the factory. Do not confuse this with the Engineering build which you used to root your phone. They both have the same filename, namely ESPRIMG.zip, but they are too different things (the Eng build is about 1MB smaller in size). Make sure you download the one from above and place it on the root of the memory card. Don't use the one you downloaded to root the phone.

STEP 3:
  1. Power off the phone.
  2. While phone is off, press and hold Volume Down, then press Power button to turn phone on in HBOOT mode (white screen with 3 green skateboarding Androids down the bottom).
  3. The phone will search for and detect the ESPRIMG.zip file and will perform a verification to check signatures, etc. This will take about a minute and you will see a blue vertical bar filling up in the top-right hand corner of the screen.
  4. When the blue verification bar completes, it will ask you in red text if you want to apply the update. Press Volume Up key for yes.
  5. This will take a minute or so as well and you'll see a different colored progress bar in the top-right corner.
  6. When done, it will ask you if you want to restart the phone. Press Volume Up again and give it a few minutes.
And that's it! The phone will now boot in stock mode, with the stock radio version, and without root access anymore. You can now no longer go into Clockwork Recovery either as it won't let you apply the update.zip image. To root again, you need to follow all the steps in the root guide here.

CLEAN UP: You may want to delete or rename the ESPRIMG.zip from the memory card so that it doesn't get detected every time you reboot into console mode and run the lengthy verification check.
