One of my coworker's has a G300 and he broke the screen. He can turn on the phone, but can't do anything. Screen is constant black and doesn't recognize touch.
I tried with ADB but USB debugging isn't enabled on his phone. He use the original B952 ROM doesn't rooted or anything.
I tried to unlock the bootloader to install CWM and mount the SD card with it, but can't unlock since USB debugging isn't enabled.
Is there a way to save the data from the phones internal SD card?
