Can't connect to PC on fastboot mode.

[Guest xSeed]

I tried to revert back to stock rom and now everything is back to stock including recovery. Now I want to flash TWRP recovery but my PC doesn't recognize my device in fastboot mode. I already tried installing several different drivers but no luck. Please help. Thank you in advance.

EDIT: Nevermind. I installed the driver from the installer partition of the device on mass storage mode. Now it works.
