So the official GB OTA has started for the bolt. It looks like due to the security issues this OTA is being pushed to all phones running stock firmware. If you are rooted and running either stock Froyo or stock GB from the prior OTA you need to flash the new OTA rom ASAP to avoid issues.
If your phone tries to accept the update automatically and you get stuck on a recovery screen you just need to boot into recovery and wipe cache and dalvik cache to restore your functionality.
You can download the rom here [Rom][Rooted] 2.11.605.5 Full Stock - RootzWiki
Since I know people still running stock may not be familiar with flashing a rom I will provide a quick how to without referring you to the sticky
1. Download the rom and verify the MD5
2. Backup your apps using titanium backup or a similar backup root program.
3. Reboot into recovery
4. Make a backup in recovery
5. Wipe Data (factory reset), wipe cache, wipe dalvik cache (under advanced in CWM) and format system (also under advanced IIRC)
6. Select the option to apply update from SD, select to choose update from SD, navigate to the rom zip and flash it.
7. Reboot
8. Sign into google, use the backup program to restore your apps.
This will prevent you from having issues with your phone trying to accept the OTA. I think you could actually apply the update zip without having to do the factory reset but until someone can confirm (scotty or worm) I don't want to suggest doing this. If you are running any custom rom then you should not need to do this.
