    Hey guys,

    I hope I'm not too late for this. I read through this but I couldn't find an answer to my issue. I am not new to rooting, which is why this is a real brain buster for me. OEM is unlocked, confirmed through adb. When i flash TWRP on my device, ADB says all is good and reboots the phone...but the phone is stuck on a screen with a white Oneplus logo with "Fastboot Mode" written underneath. It loses connection with adb, it will not go forward and boot TWRP and the only way to reboot the phone is to unplug it from the PC and hold power up + power button.

    I am using twrp-3.3.1-1-fajita.img to temporarily boot into TWRP (I tried the previous version too, same issue)

    Any idea on what is going on here?

    check your PC's device manager to see if there are any yellow exclamation(s) and did you install the adb+oneplus drivers
