After I unlocked my phone with the official tool, I am experiencing weird behavior which prevents me from connecting via adb.
Under windows no devices are listed with the respective "adb devices" and "fastboot devices" commands. Also I have lost the ability to connect to my phone via usb file transfer. I can see my phone in the root path of windows explorer, but no directories are shown.
I have tried setting and unsetting usb debug mode, but that makes no difference.
When I boot into fastoboot via power+vol down I can connect with fastboot.exe, but I cant boot (dtb not found) or install twrp.
Installing twrp seems to work at first glance. But after the flashing, my phone wont boot into recovery mode. I only see the white Mi logo on my screen.c:\adb>fastboot.exe boot TWRP_libra\twrp-188.8.131.52.img
OKAY [ 1.627s]
FAILED (remote: dtb not found)
finished. total time: 1.689s
Before the unlock (or when I was running Android 5) everything worked fine. I have even tried to update my usb windows drivers, but that didnt help either.
Might this have to do anything with Mi Sync? I have enabled my account on my phone, but I have removed the sync tools via the rom builder..
