Good day!
I had a problem with my Redmi Note 9 smartphone. Some time after installing Magisk, I noticed that the smartphone does not see devices with fast boot, it’s just empty.
All ADB commands are executed in the command line, it sees the phone, it can reboot into fastboot, but nothing can be done in fastboot.
In the MiFlash program it appears when connected for 5 seconds, then disappears. I can't flash it, all the time it says: $fastboot -s 212f41dd0410 getvar product 2>&1 | findstr /r /c:"^product: *merlin*" ||
and nothing more, just like this ad infinitum.
And TWRP cannot be installed, because... install via fastboot
I don’t know exactly what the matter is, Magisk or not.
Need some advice.
