Hello, while trying to SIM unlock following this guide: http://forum.xda-developers.com/show....php?t=2586704 and this custome HBOOT: http://forum.xda-developers.com/show....php?t=2565201
I notice my fastboot connection fails with a "USB not recognized" error after trying fasboot everytime.
Never had this problem before, and ADB recognizes my device correctly every time. Re-installed drivers, and tried other laptops, but all fails at fastboot, which never happened before.
Some info: Windows 8.1, latest drivers (tried different ones), S-OFF, tried various USB ports and laptops. Never had fastboot problems under Windows 8.1 before.
EDIT: I think the problem is the phone itself now after using that custom Hboot? Reason being that no matter what RUU I try, when it tries to start the bootloader, the USB not recognized appears just like when I boot into the bootloader and try to fastboot any command.
