For those who are still wondering about how to reinstall android after UT, here are some hints for you:
Check the usb-c cable. They may differ very much. In my case I had 3 very good ones… one from Samsung and two from Realme which I have bought on ali. To my surprise only one of them worked properly. I have no idea why. However, all of them work great for datatransfer and charging on all devices. Install all 3 Android USB-drivers which are attached to the package archive like you can see on this image If you are flashing through Android Flash Tool and get stuck at the installation process with “In Process” pending forever you should unplug your device and press a power button to switch it to the fastboot mode then reconnect it on the chrome browser page and it should start working from then.
