    Requesting some help / advice with the following issue:
    • Have a rooted htc thunderbolt running gingerbread on vzn
    • phone randomly shuts down and when trying to reboot it freezes on a screen that has image of droid robot looking at a ! inside a triangle. No words or explaination. Seems to only happen in middle of night.
    • Only way to get phone going again is via "factory reset" on revolutionary's boot loader.
    • Thinking it might have to do with a recent update Verizon pushed to thunderbolts?
    I would appreciate any guidance forum members may have. having to start from scratch ea day just ain't working.

    if you are rooted.. never take any updates from carrier. these will mess you up.

    did you loose ROOT?
    if not.. then:

    you should reflash your ROM. or a new ROM.

    first.. you need to search for a custom ROM you like... in that post.. there should be instructions to Flash that ROM. you should also ask in that thread, for more help if you are confused about any of the steps

    since you are new.. choice the ones that have the most post.. and are not betas or nightlys
