Troubleshooting & Common Errors
- Bricked after a custom ROM flash: This is a common situation for a developer-favorite device. As long as your PC can detect the phone in Fastboot mode (Power + Volume Down), using Method 1 to flash the official Fastboot ROM will almost always bring it back to life.
- Bootloop after flashing a custom ROM: You must use the "Format Data" option in TWRP before flashing. This is required to remove the stock MIUI encryption and is the number one fix for bootloops.
- Mi Flash Tool shows a "sahara" or "xbl" error: This is a common error on older flagships. It can indicate a bad USB connection or a driver issue. Try a different USB 2.0 port and cable, and run the tool as an administrator. In rare cases, it can mean a hardware fault.
- "The system has been destroyed": This is a generic Xiaomi error for a failed boot. It is easily fixed by forcing the phone back into Fastboot mode and flashing the stock firmware again.
