If the Redmi phone is responding to charging (lights, vibrates), but does not turn on, the problem is most likely software.
- 📱 System freeze after update (MIUI or hyperos).
- 🛑 Failed firmware via Fastboot or Recovery.
- 🧹 Application conflict (especially after installing modified applications) APK magisk).
- 🔄 Reset to factory settings interrupted at half the process.
How to restore work:

| The phone gets hot when you connect the cable | Short circuit in the food chain (often after moisture is ingested) | Diagnosis with a multimeter, replacement of damaged elements |
| No reaction to the power button, but the phone is determined by the PC | Failure of the Power button or its plume | Replacement of the button (1-3 thousand rubles) |
