How To Unroot Verizon HTC Thunderbolt And Return It To Factory Stock

htc-thunderbolt-unrootThe Verizon HTC Thunderbolt was rooted (see here and here) as soon as it arrived on the scene, allowing us to flash custom recoveries and ROMs on it. Not to mention apps like Titanium Backup or Screenshot apps. While, an Android device’s true potential is only unleashed after rooting it, there are some who like their devices in stock condition after experimenting a bit with a rooted one. This guide is for those very users, so read on to unroot your Thunderbolt.

Let’s get down to business!

Instructions:

  1. To begin, extract the Unrooting kit to any folder and rename the stock firmware to PG05IMG.zip.
  2. Copy the firmware to the root of your SD card.
  3. Now run command prompt on your pc and enter the following commands, hitting enter after each command:
    adb push misc.img /data/local/
    
    adb push busybox /data/local/
    
    adb shell chmod 777 /data/local/busybox
    
    adb shell
    
    su
    
    /data/local/busybox md5sum /data/local/misc.img

    If the output for the MD5 sum is anything other then, c88dd947eb3b36eec90503a3525ae0de, stop right here and restart the process again.

  4. Continue entering these commands:
    dd if=/data/local/misc.img of=/dev/block/mmcblk0p17
    
    adb reboot bootloader
  5. At this point your phone will reboot, and you should allow it to flash the stock firmware.

That’s it! You have just reverted your Thunderbolt to a completely stock/factory condition.
