Booting loop help Huawei p9 LITE ALE-L21

Hello

Give this a try.

The best thing that you can do right now is to check if the problem is caused by a system glitch. You will need to perform a factory reset on the phone from the recovery mode. Take note that this action will erase your phone data.

*Hold down the Power key to switch off the device.

*Press and hold Volume Up and Power key.

*Release the keys as soon as the Huawei logo appears on the screen.

*You should be in a Recovery Mode menu.

*Navigate here by using Volume buttons and select options by using the Power key.

In case the problem still occurs after the reset then this could already be a hardware related problem in which case you will need to bring the phone to a service center and have it checked
