glad you got it working I had the same issue and following worked
need to run TWRP from PC command or system partition tick setting RW in the TRWP if you have TWRP installed in phone
Thanks I just decided to update my mi11 to latest stable update and got the same issue trying to install OTA with latest TWRP [BOOT]3.6.2_12-Mi11_v6.3_A12-venus-skkk_c5a45bf1 installed in recovery_Ramdisk , so at the time instead I just booted with twrp from PC doing the command and rom flashed...
I don't have that permission but battery life still not good got worse since updated, before update used to be around 40% by late evening now its like 15% by late evening usage is the same :(
I actually did search but couldn't find it , link is exactly what I needed thanks, reading around here if I know answers to others questions I have learnt to become patient even if it is obvious :)
Thanks again
This can't be flashed using twrp it's not recovery ROM it's fastboot ROM
Maybe later on get recovery ROM which can be updated with twrp but you'll have to wait
just flashed mi 11 from stable xaomi.eu 12.5.16 to 13 using windows_fastboot_update_rom.bat no data loss, everything seems to be working fine, thanks for the great support :)
