Absolutely i agree with you, everything works even flashing magisk, but many people have tried flashing miui recovery roms but it doesnt work.. not sure why though, it should work like normal like in other phonesIt works , stop spreading misinformation. You can flash Magisk with it
(I copied from the TWRP topic, I'll delete it there)
What did I do,
1- usb debugging ok (inside miui stock)
2- adb reboot bootloader (direct to Fastboot mode)
3- fastboot boot twrp-recovery-venus.img ---OKAY
--------TWRP----- 6option(left-right-downleft)->Globe->English->Set... ok (a litte expectation of hope)
4- download the last MiuiMiX #venus in mmx-telegram-site
5- miuimixrom to mi11 by pc in root directory...
Where did go the rom in twrp path ?????
the path in my mi11 is /data/media... or /media/data (sorry, I do not remember for sure)
6- MiuiMiX Installation Guide and "Install Rom"
7- Everything ok... Now a free Mi11 unlocked and with a new rom (for now)
