Hey, my newly bought Tattoo became unbootable a few days ago.
It worked perfectly fine two days ago, then it started to randomly reboot itself, but after that, it became completely unbootable, as in, it was stuck at the "TATTOO" screen. The phone internals are completely untouched, no custom images, not rooted, no nothing, it's factory fresh.
The battery is full too, and I didn't install anything that could possibly have corrupted the bootloader (or whatever is failing to load).
I already tried to wipe the user data _TWICE_ (using HOME + BACK + POWER) with no success. I'm also perfectly able to get into HBOOT (using VOLDOWN + MENU + POWER), and connect via usb (using "FASTBOOT USB" from HBOOT). However, I can't completely wipe the cache with fastboot.exe from the android-sdk, since it doesn't allow it: "erasing 'cache'... FAILED (remote: not allow)".
I really appreciate any help, I just got this phone, and I really don't want to buy a new one (I can't return it, it's a used one...)
