I have had a similar problem with my phone, and I think I have found a solution. I had this phone for several months without any problems, until I tried to perform a software update. Immediately afterwards, my phone started to periodically reset itself, or sometimes shut down completely. This would happen every hour or so. Every time it would reboot, whether on its own, or due to me turning it off, it would display a message telling me the update could not be completed. I have come to believe that there is a problem with the software update, or the update process, that leaves the update unfinished, and the phone constantly thinks it has to reset to complete the update.
Try these steps:
1. back up all of your contacts, whether to the sim card, or whatever other storage device you have.
2. back up all of the pictures, texts, mms, ringtones, music, games that you may have installed since you purchased the phone, anything you don't want erased. If it came on the phone when you bought it, it won't be erased. You can save this stuff to a memory card of some sort. I sent all my pictures to my email via mms.
3. Go to Menu > Settings > Phone >Restore Phone. (Not reset phone, but RESTORE phone) You will be prompted for your password. If you never set a password, you will be asked to create one. THIS WILL RESTORE YOUR PHONE TO FACTORY SPECS AND SETTINGS! LIKE IT JUST CAME OUT OF THE BOX. YOU WILL LOSE ANY INFO YOU DON'T BACK UP!
Since doing this, I have not had the reset / update failed problem for more than 24 hrs, and it no longer gives me the "update failed" message when I reboot the phone. Hope this helps.
