[RS Guide] How to Get Rid of OTA Forced Reboots on Rooted Phone
Ok, so you have rooted your phone, and decided you would install the latest OTA update from Verizon. Now the update fails to install and your phone constantly reboots. Here is how you fix the problem.
Thanks for all the RS Members and Forum Members that have helped discover these solutions. We are not responsible for any damage done to your device by using these methods. They should be harmless, but you will possibly loose your data in the process.
There are 4 different solutions outlined here. Starting with the least damaging to your data. Please try them in order until you get your phone back working. Most people will be able to recover using the first method. But the other methods are included in case the first one doesn't work for you.
First of all when the OTA fails you should be left in ClockworkMod Recovery. You will know that is where you are based on the following menu that should be shown on your screen.
ClockworkMod Recovery v3.0.2.5 (ok if your version doesn't match)
Use vol keys to highlight and home to select.
- reboot system now
- apply sdcard:update.zip
- wipe data/factory reset
- wipe cache partition
- install zip from sdcard
- backup and restore
- mounts and storage
- advanced
- +++++Go Back+++++
Method 1: (thanks to sonicbuffalo for posting this method)
1) Once you are in ClockWorkMod Recovery, scroll down to "Wipe cache partition".
2) Select "Wipe cache partition" using the home key or power button.
3) Now, scroll down to "Yes - wipe cache".
4) Press the home key or power button to perform the wipe.
5) When done, restart your phone.
6) Your ThunderBolt will boot into the Android operating system and will say that the UPDATE FAILED.
7) Choose Cancel to stop the update.
8) Restart your phone one last time and you'll see that the "Powering Off" loop is gone.
Method 2: This will delete your data
1) Once you are in ClockworkMod Recovery, select "wipe data/factory reset" using volume keys.
2) Press home key or power button to select.
3) Answer Yes, by scrolling with vol keys and home or power key to select.
4) When phone reboots, the powering off loop should be gone.
Method 3: This only works if you have a Nandroid Backup from prior to accepting the update.

2) Select using the home key or power button
3) From next menu select "restore"
4) Choose your backup from list and select.
5) Answer yes to restore backup
6) When phone reboots the "powering off" loop is gone.
Method 4: This is a last ditch effort if all other methods fail.
