Question Huawei mate 20x

[ihariff]

Hi,

I am hoping someone can help please!

My phones memory was almost full and my son decided to download a game. My phone turned it self off and since I can't turn it back on. My power button has been broken for a while so can't restart it this way. When I plug my charger in then a red circle with a bolt sign comes up and then goes away 5 seconds later. I have tried connecting the phone to my laptop via the lead but the laptop is not picking up phone.

I want to be able to get all my data exported but I can't.

What are my options? If I change the battery would that resolve it or is it a software issue. Any help is greatly appreciated.

Welcome to AC!
It sounds like a repair shop would be able to assist you further and you'll have to decide if it's worth fixing or any data can be saved.
Go to a reputable shop.

Welcome to Android Central forums. I looked up your phone model and see that it was released in 2018. It's more than 7 years old which is kind of old for an Android phone, so I can understand why mustang7757 mentioned that a repair may not be worth the cost. I have a couple of things you can try before that however.

First things first. Plug the phone in to the wall and allow it to charge. You mentioned plugging it into a laptop, I believe just to try to access the memory but we'll talk about that later, for this you want to charge normally so just plug it into the wall and allow it to charge for an hour or so before taking any other actions. Even if you believe it isn't charging, please just allow it to sit on the charger anyway.

After between a half hour to an hour of charging, test to see if the phone will restart normally, the way you usually restart the phone.

If the phone did not power on after the previous steps, remove the SD and SIM cards and attempt to restart.

Attempt a virtual battery pull. Occasionally if power is suddenly cut to a device the software can bug out and this condition can carry over to the next restart as the phone may attempt to start or continue a process that wasn't ended properly. Back in the day we could physically pull the battery out and call it a day but with sealed devices there is no easy way to do this, so we're left with a simulated battery pull. To simulate a battery pull, press and hold the power button for an extended period, at least 10 seconds. I would recommend 20 to 30, as this action will not hurt anything. If you see the splash screen after at least 10 seconds of holding the power button, release it and see if the phone restarts.

Up until now we have only tried to restart the device normally and get it to boot up to the OS. If none of that worked, let's try to boot into recovery. To do this press and hold the volume up button and the power button at the same time. Hold both and release the power button when the splash screen appears, holding the volume button until the phone fully boots up. Use the volume buttons to navigate and the power button to select. Navigate to wipe partition cache, select that and allow the process to complete. Once done, navigate to reboot and allow the phone to reboot normally.

Let us know if any of these worked for you.

As far as the laptop connection goes, you need the phone fully booted and unlocked before the two can communicate. There is no way around this, it is a security feature to prevent anyone plugging in someone's phone and taking whatever they want off of the device. You also wouldn't see anything on a device that is powered down. The phone's memory doesn't work without power.
