So I'm having a panic attack. I'm an average Android user who knows nothing about computer language. I'm on HTC Thunderbolt. My phone has never been rooted. I was running the latest firmware update (I don't know which version) and suddenly the only screen I can get reads this: *** LOCKED *** *** Security Warning *** MECHA XD SHIP S-ON HBOOT-1. 05. 0000 MICROP -/ RADIO-1.49.00.0406w_1 eMMC-boot Jul 19 2011, 14:51:08 FASTBOOT USB <VOL UP> to previous item <VOL DOWN> to next item <POWER> to select item BOOTLOADER REBOOT REBOOT BOOTLOADER POWER DOWN I have tried just about every option. I clicked on every item and they all lead me back to the original screen. I pulled the battery on the phone. I just don't know what to do. I really can't afford to lose my phone. Can someone help me? WHY DID THIS HAPPEN?!
