Screen not responding to touch - Huawei Mate 20 Pro Questions & Answers

Hey guys,
So im experiencing something very weird. My phone randomly stop responding to touch. I cannot unlock the phone, I tried safe mode and now phones in airplane mode. Cant factory reset as it requires me to type "yes" on the screen. I don't have a way to connect a mouse to a USB c port atm. Also when it boots, the huawei logo isnt centered(the fancy blinking one, the normal initial white one with the android logo underneath is fine) and the fingerprint scanner logo is way bellow where it usually is. Any suggestions on what to do? I cant send it to service center as there are none in the country I am in right now. Is there a way to use my pc to somehow emulate a mouse on my phone? Any methods of force factory reset? Looking for anything that might work people!
Thanks, hope to hear from some of you guys soon.

Really weird thing happening with Galaxy s i9000M

I have just tried to disable half the bloat wear on my galaxy s, and i must have frozen something that i shouldn't have and now my screen isnt working properly. I have the top status bar with the service bars and the battery meter and when the phones screen lock is on it all looks normal but when i unlock the phione the whole screen goes black and only the status bar is able to be seen. I cant access the menu or any apps at all. I have tried to get into download mode to add different firmware but i cant get into download mode or recovery mode in any of the ways that i have researched. I can still recieve emails and texts and voicemail but i cant reply as i keep getting this error every time i try to do anything: Andriod.Process.acore has stopped unexpectedly. Does anybody have any idea how i might be able to fix this problem. I have tried to connect to andriod explorer but it wont recognize my phone the same thing with Kies. If anybody has any ideas as to how i might be able to fix this that would be greatly appreciated.
Is there no reboot button holding sequence that will enable you to enter recovery?

[Q] display bad?

Hello friends.
Please help me out, my Xperia mini pro doesnt power on. I get vibration when press power, but no display. After a few seconds I see the keyboard lights on, but thats all. No boot, no animation And no Led blinking or anything.
I managed to connect trought adb And the logcat show cyanogenmod And stuff like that. Like if the Phone has booted. But I cant receive Phone calls either.
How can I find out if I have a problem with display? Tried a few adb commands with no luck
I dont really know what happened with the phose cause its my son's Phone And he says: I dontknow
When I gave this Phone to my son it had cyanogenmod, rooted And with recovery. But dont know if thats working, as I said, no Led info.
Thank you

If it's an Xperia x10 mini pro (2010) device it may be one of two things: either a broken flex-cable (which connects the phone to the display) or a bad battery.
If it's an Xperia Mini Pro (2011) device, i suggest asking in their forum... (although it may still be one of those two issues)
Its a 2010 device, sorry for not clearify that. the model is u20i, so no internal battery.
As said before, dont know why I cant receive phone calls. I also removed the lock screen if any via adb
you say its the flex cable, how can I know if its booting correctly?
Thank you

Not sure how you can check if it's booting properly, but it's not that hard to figure out if the flex is broken or not, there are tutorials for that on youtube.

Screen android phone broken, no USB debugging on, mouse working no visual

Hi guys,
My screen recently died. Before fixing it at a specialized shop, I want to retrieve the data from the phone. Sadly the phone is pattern-locked and until I unlock it I can't access the data when I connect it to my PC. The screen is essentially dead. The image is almost totally black except for small layer in left top corner and the touch sensor is unresponsive, but other than that the phone works and receives notifications and so on.
USB Debugging mode isn't active on the phone and thus I can't replicate the screen of the phone on my PC through software alone, when I connect it via micro-USB. I also didn't think of this problem in advance and I'm not registered on Sony's FindMyMobile or any similar apps.
I tried using a HDMI-MHL adapter and I confirmed that the phone is indeed working because I'm able to get the phone screen's image on my TV. The problem is I can't actually interact with the phone because as I said earlier the touch sensor is not working.
The HDMI-MHL adapter I've used also seems to have a micro-USB port but that seems to work for power only. If I connect a USB-OTG cable on it and connect a USB mouse to it I get image but no mouse. If I connect the USB-OTG and the mouse, alone, I get a mouse cursor but I can't see what I'm doing (phone vibrates as I 'try' and draw the unlock-pattern blindly).
So, Sony Xperia Z3 Compact screen is dead, I wanna connect my Xperia to my TV via HDMI AND use a mouse at the same time to control my phone. Is this possible_
I also thought of another option... go to recovery mode and flash a zip that removes lock. I thought of trying step by step (switch keyboard and TV al the time just to get at point where I can find zip file and flash it). Unfortunately in recovery mode the phone does not allow to stream to TV. It only works when phone is after SIM lock.
Two additions: by removing and re-installing ADB on my laptop my phone is unauthorized. Only a matter of clicking on yes/allow on phone but that's not possible and TWRP 3.1.1-0 is installed.
Anyone any clue? I know I ask a lot but I'm searching the internetz for 2 days now and I'm devistated.
THNX a great bunch!!!
ciao

PS Copy/paste a part of the text from a guy from the internet who had exactly the same problem as I did but his thread ended a few months ago without result.
Just 30 minutes after my post I magically had all the dots correct and that blind!!! So turned on USB debugging and got rid of lock pattern. It was a nice three days of my life Guess there was no solution than getting lucky like I did or screen replacement and getting all your data removed.
ciao

Corrupt firmware

I bought a used Zenwatch 2 and after a week it stopped working. When I turn it on it sticks on the Asus splash screen. After talking to customer support and looking online it appears that the "firmware has been corrupted.
I made the mistake of not turning on ADB Debugging while it worked, and unfortunately the screen appears to be unresponsive so I can't even put it into Fastboot mode to turn ADB Debugging on. Of course to make it even better the watch is not recognized when I plug it in because it doesn't appear to boot enough. Since I can't get into anything it makes it impossible to reinstall the firmware.
You all are my last hope, does anyone have any insights into a way to get the phone recognized, or anything that may help? Please help me keep this from becoming a fancy bracelet.
When you first turn it on, swipe diagonally down from either direction to get into recovery or fastboot. I know you said the screen is unresponsive, but if you haven't done it before it can be tricky. Even on a perfectly working watch, I still have trouble getting it to work. Try continuously swiping as you hold the power button, even before the splash screen shows up. If you can get it into fastboot, unlock the bootloader and try flashing my ROM.

That seems to be what I am reading, but so far I have had no luck getting it to trigger into fastboot mode. I will keep trying.

Screen Broken need help to access the Data, Backing up and Reset

Hello folks, my display broke suddenly, cannot see anything except a line and some green flickering when display is on. I have most of the documents and everything stored on my SD card but the Whatsapp data is unfortunately not backed up. There are a few pictures and chat data that I would need to access from there.
The situation is like this - Display broke but the phone works also touch apparently works too since Double tap makes the display light up in green (cannot see anything), and double tapping again makes the screen off. There are notifications coming. USB charging works. Shows up on the PC but the MTP won't show anything since screen is locked. I rebooted the phone which was the mistake !! because now it asks for pattern. I cannot unlock this, tried blind so many times but since I disabled the vibration. It's hard to get the pattern. Fingerprint scanner works but it won't unlock with it (so it just vibrates saying need to use pattern on screen due to reboot, the usual behavior)
Phone specs and OS are in my sig - Stock OS, Rooted, TWRP.
Can anyone please help if there's any way to access the filesystem ? It would be great if there's a way for accessing the data. My other request would be, can I make a data backup of the ROM as is with LGUP ? then reset it all before sending to LG for a full repair as I like this phone a lot.
Thank you for your time.
boot to twrp and then plug it in on PC and browse the file there? if you cant go to recovery from power off, maybe go to fastboot first then do the command to go to recovery.
figure out how to cast the display on a tv? i think the usb port supports HDMI output so maybe plugging it to a tv would work.
