Although the boot loop issue occurs for many reasons, most issues can be resolved by a factory reset.

Here is what you can do to complete the hard factory reset through power and volume buttons:

1.  To perform the hard factory reset via recovery mode, first, you should make sure your Android device is not in charging status.
2. Press down the “power” button and “volume up” button at the same time for a few seconds.
3. Then your phone will access the recovery mode.
4. You can leave the buttons while you see the Android logo on your screen. If you fail to see the logo, you have to repeat the mentioned steps until you see the Android logo.
5. Now you can view the settings via volume up/down and select options via power buttons.
6. Scroll down to find and click the “wipe data/factory reset” option.

Then your device will start to hard reset. You may need to wait for a few minutes until it completes the process.
