How to translate Xiaomi Redmi Note 8 Pro from Eurotest to Rostest: full instruction

What is Eurotest and Rostest in Xiaomi smartphones?

If you bought the Xiaomi Redmi Note 8 Pro abroad or got it with your hands, chances are good that the device works in Eurotest mode (EEA). This means that the firmware is optimized for European communication standards, and some Russian frequencies are optimized for the same.

Transfer of the smartphone from Eurotest to Rostest requires unlocking the bootloader, installing a custom recavator (for example, TWRP) and firmware official or modified version of the software. The process is not more complicated than flashing Android, but requires care - errors can lead to a "brick" (inoperability) of the device.
