xperia x8 hard bricked, and "usb device not recognized" resurrected by restoring a working phone full dump. But the usb problem not solved. I've change the usb cable, using different pc, even change the phone usb connector, it's still the same.
PS: when I plugged the charger, its charging. I guess the problem is in the data line of the cable


and here's the dump file, if anyone need it.
