Why Xiaomi is stuck in Fastboot: 7 main reasons
Before you start a repair, it is important to understand what caused the failure, and 95% of the time, the problem is due to one of these causes:

- 🔓 Damaged bootloader after failed unlocking via Mi Unlock Tool (especially relevant for devices with a binding to the Mi Account).
- 🖥️ Failures in operation ADB/Fastboot PC: outdated drivers, conflicting software (for example, antiviruses block commands).

- 📡 Conflict with Custom Recovery (TWRP, OrangeFox) if they are installed incorrectly.
