What should I do if my Xiaomi phone won t turn on after factory reset

The reason why your Xiaomi phone won't turn on may be due to data update failures or errors during a factory reset, creating the illusion that your Xiaomi phone won't turn on. The easiest way to solve the problem is to clear the cache data in your phone to solve the problem.

1. First of all, press and hold the "Volume Button" and "Power Button" in the shutdown state to turn on the phone, and the phone will boot into Recovery mode.

In this mode, the touch screen is temporarily unavailable, and you need to use the volume button up and down to move the option and the power button to confirm the operation.

2. In the language selection interface that opens, use the volume up and down keys to select "Chinese Simplified", and then press the power button once to confirm.

3. Then select "Erase Data" in the "Main Menu" that opens, and press the "Power Button" to confirm.

4. After the data is cleared, the program will return to the "Main Menu" interface, and then use the volume to select "Restart Phone" up and down, and press the "Power Button" to confirm.

5. Then select "Reboot into System 1 (Recent)" in the "Restart" interface that opens, and press the "Power Button", and the phone will automatically restart.

6. After the reboot is completed, the desktop of the Xiaomi phone should appear again.

Brush or return to the factory for repair.

Common sense with a wire brush:

1. Keep the phone completely turned off, press and hold [Volume-] and [Power Button] at the same time to enter fastboot mode, and connect the phone to the computer through the US cable.

3. When the Xiaomi Mi 2S is successfully recognized, you can click the "Flash" button to officially enter the flashing process.

1. The logic circuit is not normal and does not turn on.

The logic circuit focuses on detecting the chip selection signal CE and license signal OE of the CPU to each memory, these signals are very important, but the key is to look for these signals, because more and more mobile phone logic circuits use BGA packaged integrated circuits, it is very difficult to find these signals.

If possible, it is best to refer to the drawings to find these signals and their measurement points. The chip selection signal is a pulse signal that jumps up and down, if there is no CE in each memory, it means that the CPU is not working, repair welding, re-soldering, replace the CPU or carefully check whether the conditions for CPU work are available.

If there is no chip selection signal for a memory, it is usually because the memory is damaged. If the CE signal is present, the CPU-F is working properly, and the fault may be a software failure or a bus failure or a memory failure.

Solution: Generally, repairing or resoldering these chips will solve most of the problems. When the normal chips cannot be turned on by soldering or substitution, and the reading and writing cannot be passed by using the disassembly-free maintenance instrument, the peripheral circuits should be measured one by one and these chips replaced.

2. The software is not normal and the computer is not booted.

In the process of turning on the mobile phone, if the software can not be passed, it will not be turned on, the software error is mainly due to the abnormal memory data, when the line is not obviously disconnected, you can replace the normal chip, version or rewrite the software, some of the circuit in the chip will be damaged, and it can not be passed when rewritten. When rewriting the software, the original data should be saved for emergency repair.

The Xiaomi phone can't turn on after factory reset is solved as follows:

1.Unplug the battery and reinstall it to see if it can turn on normally.

2.Whether it can enter recovery. Ways to get into recovery:

In the shutdown state, first press and hold the "Volume Up Button" and then press and hold the "Power Off Button", and let go when the boot screen appears, and then you can enter recovery. If you can enter Recovery, please switch the system under Recovery and back up your data, if it is not successful, you need to erase all data.

3.Whether it can enter fastboot. Ways to get into fastboot:

In the shutdown state, first press and hold the "meter key", then press and hold the "volume down button" and then press and hold the "shutdown button", and let go when the boot screen appears, you can enter fastboot. Please connect your mobile phone to the computer and flash a complete system package with the method of miflash.

Hello, the CPU, motherboard, memory, graphics card, power supply, hard disk, optical drive and other accessories in the computer host are short-circuited, which will cause the computer protection circuit to work and cause the computer to not be able to boot, so the next step is to eliminate the problem one by one.

According to your description, after pressing the computer switch, the CPU, power supply, and graphics card three fans will stop after a while, and the first thing you should check is whether the power supply itself is faulty, especially the Internet café machine works for a long time, and the failure rate of the power supply is relatively high.

Power detection method: unplug all the power connectors connected to the motherboard, hard disk and graphics card, find out the row of 24-pin connectors of the power supply, and use the wire to short the green wire with the black.

In the case of normal power supply, use the elimination method to plug in the power supply interface on the motherboard first, and try whether the fan will automatically shut down after powering on, and then connect the hard disk for power supply, connect the graphics card for power supply, and press the on/off button to test whether it will stop every time you connect to the power supply, and finally try to determine whether the component is down.

1. Press and hold the power button for more than 10 seconds to try to force restart. If it can't be restarted, you can try reinstalling the battery for models with removable batteries.

2. Make sure that the phone is turned off due to low battery. If yes, use the original charger to charge it for half an hour and then turn it back on.

3. If you are sure that the phone has power, press and hold the volume up button and the power button at the same time or press and hold the volume down button and the power button at the same time in the shutdown state to see if you can enter recovery mode and fastboot mode. If you can enter the above two modes, press and hold the power button for more than 10 seconds to try to restart when you are in both modes.

4. If the operation in "4" cannot be turned on, you can enter the recovery mode with the phone turned off and select "Clear Data", or you can connect to the Xiaomi Assistant on the computer in recovery mode and select "Clear Data".

5. If the clear data is still invalid, and the phone has logged in to the Mi account and unlocked the BL lock, you can guide the Miflash line to try.

6. If none of the above methods can be solved, you need to go to the after-sales inspection.

It is recommended to delete the data and try to see if it is normal!

You can enter the recovery mode to erase the data directly.

The method is to shut down and press and hold the volume button on and the power key at the same time to enter the recovery and select with the volume key, confirm with the power button, select Clear Data, Clear Cache'Clear all data, this is the three clear.

Hello friends, in this case you need to re-erase your phone's system data.

You go into the recovery mode of the phone, and then clear the data again, if it doesn't work, you can only do after-sales processing.

What does it mean if it can't be turned on, is it a black screen that doesn't respond, or is it stuck in the boot interface?

Is the phone Xiaomi or Redmi?

I can only flash the phone, what brand of mobile phone?
