Solutions for each case:
- Hanging on the logo: Try to go to Recovery and repeat the reset. If it doesn't work, run the official firmware through Fastboot (see Method 3). For custom firmware, check compatibility with the bootloader version.
- Unresponsive: Connect to charge for 30 to 60 minutes, maybe the battery is dead. Try to pinch Power Button + Up/down Volume for 20 to 30 seconds (forced reboot). If it doesn't work, bring it to the service, there may be a malfunction of the board.
- Requires Mi Account: Enter the last account associated. If the account is deleted or forgotten, contact Xiaomi with proof of ownership of the device (check, box). For unlocked devices, you can flash the firmware through Fastboot with the Clean all and lock option (but this will delete all data).
If none of the methods worked, there may be a hardware problem (e.g., a damaged flash memory) in which case, contact the service center.
