How To Fix Huawei P20 Pro Keeps On Restarting

Problem: Hi, I purchased a P20 pro second hand. It’s cosmetically good, except for a slight crack down the right hand side were the screen is slightly coming away from the case. A small bit of light shines out through it. It came with about 75% battery charge. When I turned it on it went through initial setups, e.g. Picking language, etc. It was working fine for first few days, then turned off. I thought it was simply power run out. The it happened again and then again, then it would go through restart, restart restart. Then after a few of those it would do it but at the recovery screen. Would appear. Recovery worked, but the. It would happen again and again, until recovery is not fixing it anymore. Then I tried safe mode. It seems fine. I then tried cache partition. This helped initially and I deleted all deletable apps. But it started reoccurring and eventually this was no longer fixing issue. I did manage to get it back on and I deleted all apps, turned off wifi and mobile data. Did not agree or sign up to any notifications presented during the reset startup. This was working fine, and then I took a photo and it done a restart. Any advice on what I can do here?

Solution: Initially, I would suspect that the problem is caused by a software glitch. However, since you mentioned that the screen has a crack then it’s likely that this is caused by dropping the phone. The drop might have damaged some internal component that is now causing the phone to restart. If this is the case then you should have this repaired at a service center. There is however a chance that the problem is software related in which case you should proceed with the troubleshooting steps listed below to eliminate this possibility.

Boot the phone in Safe Mode- This will allow you to check if the problem is caused by an app you downloaded as only the pre-installed apps are allowed to run in this mode. If the issue does not occur in this mode then you should find out what app is causing the problem and uninstall it.

  • Turn off the phone.
  • Power it back on
  • When you see the Huawei animation on the screen press and hold volume down button
  • You can see safe mode at the bottom left corner once the device finishes booting

Wipe the cache partition of the phone from the recovery mode – This will erase any temporary data or files stored in the phone that might already be corrupt and is causing the problem. This procedure will not erase your personal phone data.

  • Turn off your Huawei P20 Pro device.
  • Wait for few seconds until your phone completely turned off.
  • Press and hold Volume UP button along with Power button on your Huawei P20 Pro device simultaneously for a while
  • Your phone will enter the stock recovery mode
  • Use volume buttons to highlight ‘wipe cache partition’ and use power key to select it
  • Reboot the system once the process is completed

Backup your phone data then do a factory reset – This is the last troubleshooting step that you should perform in case the above steps fails to fix the problem. This will revert your phone back to its original factory condition.

In case the above steps fails to fix the problem then this is most likely caused by a faulty hardware component already. You will need to have the phone repaired at a service center.
