Can someone please help since i'm new to all this, i've looked everywhere and found nothing. I've been trying to unlock my bootloader to finally root my phone but i always get stuck on sending 'unlocktoken' (0 KB)... when i enter fastboot flash unlocktoken Unlock_code.bin in the command prompt the only thing that happens is a rectangular box outlined in green pops up but thats it. I've tried uninstalling and reinstalling htc sync and made sure it wasnt running but didnt solve anything .I also made sure my device is recognized by the computer? I dont what the problem is ? Thanks
