I flashed Nebrassy TWRP first, than ROM and Magisk. Everything works fine. Thanks to the devs.
Small hint : touchscreen starts after some seconds in TWRP
I tested it via
Fastboot boot twrp.img
works well.
Flashed recovery via twrp. After boot to recovery touch screen is not working. (all security off)
With "fastboot boot twrp.img" touch works well.
Update: Magisk flashing via twrp works
Mi11Lite5G
xiaomi.eu_multi_MI11Lite5G_21.5.20_v12-11-fastboot.zip is new uploaded. Why?
Does xiaomi.eu_multi_MI11Lite5G_21.5.20_v12-11.zip includet working TWRP?
I've just noticed that on androidfilehorst a ROM for Mi11Lite5G (renoir) for TWRP flashing exist.
I did not found a TWRP up to now for Mi11Lite5G.
I can't check because I have to wait for bootloader unlook.
