Yes, I read your post but you didn't read OP Instructions - there are no word.about using MiFlash
Read and follow OP post #1, F A S T B O O T installation, F I R S T install sctipt
That's it, you don't need TWRP (and maybe there is no TWRP for your device that supports A14 and data encryptiom).
That's why there are sctipts to run directly from Windows or Linux.They will install everything in the Fastboot mode.
Of course, your Bootloader must be unlocked and you must have proper drivers for Fastboot
Again,
no MiFlash. Quoting:
Installing with Fastboot:
- Download Xiaomi.eu ROM zip file
- Extract the ROM zip to a new folder
- Power off your device
- Boot your device in Fastboot mode (Hold volume down + power buttons)
- Connect to PC via USB cable
- Run one of the installation scripts (according to your PC operating system):
- first_install_with_data_format - with data wipe, if you're flashing Xiaomi.eu ROM for the first time or downgrading.
- update_rom - without data wipe, if you're updating from an older Xiaomi.eu ROM.
- Done!
