I have no idea what was done with phone before I got it but after turning on it's stuck at Sony Ericsson startup/logo screen. What's more after connecting to my PC Windows displays an "USB device not recognized" error. I am able to start the device in bootloder, but it displays:
and I'm pretty sure it's not what stock bootloader should display. Of course I would like to bring this phone back to the functional stage or even stock if possible.
