Fix Rooted Thunderbolt Accidently Updated To 2.3.4 Gingerbread Update [Guide]

Official Android 2.3.4 Gingerbread Update for Verizon HTC Thunderbolt is on the roll now as we reported earlier. The update is meant for phones without root and if you have accidently updated your rooted phone, then its likely you are in a boot loop right now. When its Android, there is a way and of course you can restore your phone to normal settings if you are stuck in a boot loop due to accidental application of the official update.

Here is the step by step guide to fix boot loop after updating to official Android 2.3.4 Gingerbread on a rooted HTC Thunderbolt. Please note that this method will only work if you have root along with ClockworkMod Recovery installed. Th-Bolt-GB-Update


  1. The first step is to take your phone’s battery out.
  2. Now put the battery back in and power on your device while holding Power and Volume Down buttons together.
  3. If you have ClockworkMod Recovery installed on your phone, you will now boot into ClockworkMod Recovery.
  4. Once you are in the recovery mode, use volume up and down button to navigate and press power button to make a selection. If you have assigned other keys to perform recovery functions, then you will have to use them instead of this combination.
  5. Now scroll down Wipe Cache Partition in recovery main menu and press power button to select.
  6. After this, scroll down among all the “No” option and select “Yes –Wipe Cache” option.
  7. Now your phone’s cache will be wiped.
  8. After your phone’s cache partition has been wiped, go back to recovery main menu and select Reboot System Now.

Now let your system reboot and you will not end up with a boot loop this time. This will boot your phone in the ROM you were previously running and you will get an update failed popup message. In case this method doesn’t work for you and you already have a Nandroid backup on your phone, then choose that backup from Backup / Restore options in CWM recovery and flash it. This will restore your phone according to your backup’s settings. The method isn’t recommended if you had important data / apps that you installed after making the Nandroid backup.

There are a couple of other options available as well on the official XDA thread posted here. You can give them all a try and one of them is bound to work for your phone. If you think that you have a bricked device, then the best thing to do is contact your carrier’s support and let them know regarding your issue.
