OnePlus 7T
Hallo i did root with my op 7T EU version HD1903
After root with magisk wasn't working Wifi so i tried to find original firmware and install it with fastboot.exe file.
After this i cant run phone anymore im getting now only blackscreen and after some time i get access to fastboot/ recovery
but problem is i have in recovery restarted system setting and i think it shutted down USB debugging.
If i try find device with adb is then only possible in recovery mode but device is unauthorized .
Phone is without password.
If is there any way to repair it i will be really thankful because im already working on this about 14 hours.
Thanks for every help
