The process of transferring the smartphone to Fastboot mode
Fastboot is a special diagnostic mode that allows you to change the software of the device. Unlike the usual recovery mode, Fastboot gives you direct access to the memory partitions, which is required to work with the bootloader.
To get into this mode on Xiaomi Redmi 8, turn off the smartphone completely. Then simultaneously press the volume down and on buttons. Hold them until the image of a hare repairing an android appears on the screen or the inscription FASTBOOT.
If the phone just turned on in normal mode, you let go of the power button too late or pressed the volume button too early. Try again, keeping the press synchronized. In Fastboot mode, the screen remains black, except for the characteristic logo, and the device does not respond to touch.

Common mistakes and ways to solve them

Most errors are not related to a phone breakdown, but to an unstable Internet connection or outdated drivers on the computer.
Actions after successful unblocking
Once the process is complete, the phone will automatically restart, and the first boot will take much longer than usual, from 5 to 10 minutes, which is normal, as the system resets the security sections.
