Yeah ! I've same problems on my redmi note 8t with crdroid 11 !!!Choosing "Advanced Restart" changes nothing on my phone.
Have it up and running and rooted. So far no problems whatsoever. Great job.
Edit: after rooting advanced start is working. Not sure if that had anything to do with it but before that I had to use volume keys to get into bootloader.
I also have to wipe data after installing rom clean flash. And I also have the problem of advanced restart menu... But my RN8t isn't rooted...
I found that the reboot advanced menu was working before entering the PIN code from the SIM card, as well as before entering the screen's devouring code. Once this second code is entered, I lose the reboot menu that turns white, ugly and without the advanced options ...
Have you found the solution (without root) to obtain the advanced restart menu ?
