Can't boot phone all of a sudden, totally stock - Huawei P20 Pro Questions & Answers

Hi all
Wondering if someone can help please. All of a sudden yesterday the screen wasn't working on my phone, but it was still streaming music via Bluetooth to my car.
Now I can hold the power button for ages and it vibrates, and sometimes gets a white Huawei logo on the screen, but it won't show anything on the screen.
Any ideas how I can force it to boot up please or do you think it's broken?

HELP! Phone boots but no responce after boot.

I am in the process of calibrating my battery. It was full and finally died after a good while. I put it on the charger and waited a couple minutes and tried to boot it up because I needed to make some calls and it goes thru the boot screens and animation and will dim but then it goes black. I press the menu button and end button to turn on the screen but it doesn't work. It will boot into recovery and the buttons work there. I have no idea whats wrong with the phone. Can anybody help me with this problem? Thanks in advance.
Edit: When I plug it in via usb the screen turns on but there is no touch response when I try to slide the unlock tab or sound tab.
I have no idea what caused it or fixed it. Randomly happened and randomly fixed itself.. everything is working fine now.

can someone help me fix my phone loop?

Hi all im really looking for some help before i give in and send my for repair. I have only had it a week and earlier today it suddenly stopped working but just before it did it said the xperia home has stopped and then the phone went off and wouldnt turn back on. When i finally managed to get it to come back on i get just the sony logo then a blank black screen with a backlight on and nothing else this then loops back into the sony logo then the blank screen. Iv tried charging the phone. Connecting to a computer does not work as it cant recognise the device. (otherwise i could have reset the phone). Iv tried volume up and power get the three vibrations then it ends up doing the same thing when i switch back on. Then volume down and power while plugged into computer but the green light comes on for a brief second then goes again. Im really baffled as to whats happened and any advice would be really appreciated.
Thanks in advance, sorry for the long post

HELP! Xperia SP completely FROZEN!

Hello everyone.
A few minutes a go I was listening to some music on YouTube, with my headphones, and the phone was charging - something usual.
Suddenly, it freezes. It simply stopped working. The screen is still on, with Youtube, but there is no sound output, and the keys are unresponsive, everything is unresponsive. Even the led bar is still on.
I have tried several key combinations in order to reboot the device but with no luck. PC Companion doesn't recognize it.
Help please!

Press the yellow button underneath the back cover to reset the device (hold it 10 seconds and wait for 3 vibrations then turn it on again)

I already solved the problem by letting the battery drain completely. When I had the issue, I've tried to press the yellow button but with no luck, it wasn't working.
Thank you anyway!
It is working. You just had to hold it for a few seconds until the phone vibrates 3 times and let it go

I think the display is dead. Take it to a service center and see if they can diagnose it.
Oh god --'
I saw that there was a solution, put it in safe mode, but how can I boot it in safemode by the buttons ?
I mean, how to boot it in safemode when the phone is off ? I cannot get the safe mode by holding "Power Off" and typing "yes" you know.
Thx for the answer
