OnePlus 7t GM1905 (North America)
'fastboot reboot fastboot'
Phone boots to Chinese screen (and stops).
computer powershell stuck at '< waiting for any device >'
If I manually select boot to fastboot on phone, I get error: 'fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.'
I got my phone - first OnePlus
I installed msm xtended rom, no problems
I installed AOSIP rom, no problems
I installed Omnirom (had to dump a payload file, but got it up and running)
I wanted to go back to msm xtended rom
The phone won't reboot into fastbootd. It also wasn't recognizing with the same USB port and cable I was using yesterday.
I can still boot into stock OnePlus 7t, and access recovery, sometimes wifi/bluetooth does not turn on, but otherwise seems pretty normal.
I can try to flash roms (including stock), but they fail on the 'fastboot reboot fastboot' command. Also have problems with fastboot -w.
I used OP 7t cable, & 2 Anker cables (all USB A - USB C)
I flashed a Xiaomi between yesterday & today; maybe I need to reinstall drivers for the OP 7t(?) I don't think the 7t is recognized in device manager; at least I did not understand how to see it in device manager following these directions for Unbrick tool. https://forum.xda-developers.com/one...ce-to-t3994835
Thanks for any advice or tips on searching. And thank you for the development. Seems like searching for "fastbootd" is a bit tricky
