Frequent Mistakes and How to Avoid Them
Many users make common mistakes when turning off the Redmi Note 9, which leads to additional problems.
1. Long-term retention of the power button in normal mode
If you hold the Power button for longer than 20 seconds, the smartphone can go into emergency mode (EDL Mode), which is used for firmware, in which case you will need special software (for example, Mi Flash Tool) to recover.
2. Removal of the battery without disconnecting the plume
When you disassemble, you can't just pull out the battery -- you have to disconnect the plume first, otherwise you might have a short circuit.
3.Switch off during MIUI update
If you interrupt the update process (even forcibly), the smartphone can stand on the "brick" (complete inoperability), in which case only flashing through Fastboot will help.
4. Use of non-original chargers
Cheap charging sometimes causes the battery to overheat, which can cause the smartphone to spontaneously shut down or reboot. Always use certified accessories.
