I had an update on my Thunderbolt and it was a firmware file. After it rebooted I got a triangle with a ! point and just stays there. I tried doing the recovery mode and the volume keys aren't working. Its very frustrating. Can someone help me?? My phone isn't rooted.
Hi there! Have you tried removing the battery from the Phone? It sounds like you experienced a software crash and the device is not recoverable. You can follow me (MikeS_VZW) and DM me directly so we can check out warranty replacement options or call the warranty center at 866-406-5154.
Let us know how it all works out. Sorry this happened to you!
