GT-I9300 - USB Device not recognized - GSM-Forum

goldboxgsm · 07-27-2016, 08:40

Hi, guys!

Since yesterday, i'm trying to unlock one Galaxy S3 I9300, but keeps saying "USB Device not recognized"
In download mode phone is OK, connecting and everything, but i cannot unlock it in download mode. As soon as i turn the phone on, that error pops up.

Charging port replaced, different cables, different usb ports = same results...
I've flashed the phone , worked like a charm (in download mode), but cannot unlock it.

Any ideas?
