Ok, I have a Pre2 that has gone comatose and is stuck at the bootloader (the hp logo shows but it's not glowing yet). I was surprised to find quite a few older threads on "Stuck at hp boot logo" issues (uh oh..). But the doctoring isn't the issue really, I just want to force USB mode so I can offload all my files (unless there is a way to Doctor and keep your personal files intact). VeriZon has already agreed to swap it for a replacement. I did do volumeUP+pwr, and USB mode worked. But I can't get the device to even appear on my computers. Is this USB DRIVE mode, or is it "just charge" mode and I need something else I need to (or can) do to help this? Thanks so much in advance.
