Hello,
My Mi A2 Lite stopped receiving inputs from the screen, i.e no screen response.
Numerous re-boots by pressing power button, just brings up the screen to enter pin, where I cannot enter anything since screen is not responding. There is no sign of any defects with the screen, so i think its a software problem. i have also tried to wipe data/factory reset the phone a few times using power button+ volume up and getting up the "robot" and "no command" screen, then power button + volume up again gets me to the recovery screen. The recovery screen also has the selection to "Apply update from adb" or also "Apply update from SD card", but not sure if this will work.

I have then tried to install TWRP, for me being able to install a new ROM, but cannot do it since "Minimal ADB and fastboot" commands bring up FAILED (remote:unlock device to use this command)
I assume I must enter phone settings and press 7 times on correct menu, then enable developer mode. This I cannot do, since I cannot enter the phone.
What should I do here in order to go forward in trying to get the phone working again?
