Working custom TWRP 3.4.1B from russian 4PDA forum pages, made from TWRP for Redmi 9S.
The installation procedure is verified several times, it works if you follow the entire procedure exactly.
Redmi Note 9 Pro uses two type of displays (Huaxing, Tianma), on Tianma display the "Swipe to unlock" button does not work after the display goes out. The solution is to turn off the "Enable screen timeout" option in TWRP Settings.
