Mi 9T Pro Black Screen - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi, I've been using my Mi 9 for almost 3 years with no issues but since 2 weeks phone started to behave strange. Phone had no contact with water, didn't fall to get damage, had no chance to overheat recently.
When you lock the screen you couldn't unlock it, no reaction on power button click or tap on finger print, the only way was to hold down power button and reset the phone. The issue become more frequent so I thought this is becouse almost all the memory used but I free up 10GB and nothing changed. I told myself I need to do new backup of the phone and a hard reset but before I completed that, my Xiaomi got bricked.
The screen is black and does not show anything.
I managed to run recovery mode once but option to reboot the phone didn't help, and since that time I can't get to recovery mode either.
I thought that maybe I'll use Clonezilla to clone entire device memory do external SSD but it's not recognized as storage device.
When I plug it with USB-C cable to Windows 10 it actually shows up as Mi 9 T Pro:

}
I thought that I'll maybe I'll use: adb pull /sdcard/ but I get error: 5e08c65f unauthorized
I've backup from Dec 2021 and I managed to copy 90% of Camera folder before phone got bricked but still missing recent videos which are important to me (mostly videos of my 2-years old son).
The most important question here: Is there any other way to copy data from the device since looks like Windows computer can see it still when connected with USB?
What's the possible issue of the phone, and how can I fix that? If it's not possible to fix it at home, is it possible for Xiaomi Autorized service to repair the phone without erasing my data?
Please help! I'm in desperation, I love that device, it's design and features, I thought I'll be using it for at least 3 more years or possibly as long as it will live as I can't see any other devices that have: Popup camera, mini jack and USB-C.

[Q] D4 Screen Toast - How To Recover Files?

My D4 bit the dust tonight after having it for a year and a half. I think moisture from leaving it in the bathroom during my showers killed it. The phone gets power, but when I turn it on I get white/black static. It won't even show the Motorola boot animation. I am wondering if there is a way to get my pictures off the internal memory card? When I plug my phone up to the computer I get the little sound that my phone is connected, but it doesn't show up. I have tried a reset and booting into safe mode, but the screen just shows black/white static.

Hi, it sounds like you got the same problem as described in this thread: http://forum.xda-developers.com/showthread.php?t=2552978
I wonder if more people will pop up having this problem suddenly. Can you check if you can connect to your Phone through adb when on the static screen? That still seems to work here.
It might make sense to move this discussion to that other thread to have one location for the people having the same problem.

[Q] Can I recover this LG G2 ? Snow on screen(see pic)

I got this phone the other day, It's just got snow all over the screen (it's out of warranty) so I opened the cover, pulled off all connectors and re-seated them (didn't remove any boards, just what was accessible once the back covers were off.
I am new to Android but, this model I have replaced 2 Displays on (not this phone), seems I get one for cheap with a broken display, I fix it and someone offers me more than triple what I paid for, so I keep selling them :-/ (a man cant turn down a big profit). So I know how to pull this phone apart and replace parts if needed. I was looking to give Android a solid shot here (I am a Windows Phone person now)and not sell this one...
Not sure if the display is toast or this is just a Bricked or something else.
Note:
-If I connect to a PC, it connects fine
-When the phone is on, If I touch the lower of the screen, I hear clicking
-Double click on the center of the screen wakes up the display.
-Verzion software tool does not detect the phone (even though a drive is mapped for it)
Also to know, I have never rooted a Android device, so no idea on how to tell if it's rooted or not from the file system. Yea, when it comes to Android devices, I am a NooB.
Any idea ?
Thanks in advance !
Ok, Still trying to trouble shoot this, figuring it was a Brick or something with a lot of effort (The touch screen seems to work but, power off was a guessing game where to push to get it into bootloader mode).
I tried to go back to Stock with it, following these directions...
http://forum.xda-developers.com/showthread.php?t=2448960
Now during the process, every once an a while, on the top of the screen, I can see about 1/2 of the ICONs, it's static so it does not update but, it's the most I have seen off this display.
After showing Successful, it's still doing the same thing. accept a hair of it, static across the top of the screen.
So, does this lead down to a hardware based issue (if so, what part should be replaced), or is this display damaged and needs a replacement ?
Has anyone gone through this and can help ?
Edit, Picked up the one of the cables for the phone that the video, power, headphones all plug into, as all my problems are resulting in something that plugs into this cable, figured I would give it a shot, The only things that are left are the Main board, or the display itself.
Maybe this will fix it ?

I need to recover photos from note 9 asap

Hello, I have just got my replacement phone from Verizon's insurance company. so i been holding off a couple of days to retrieve my lost photos since my screen in severely damaged. If i try connecting it to my pc it doesnt show any files, yet the new phone does since im able to enable the MTP connection. I tried using a keyboard plugged in via the OTG Adapter, granted it works but the screen wont turn on, only when the phone turns on I can see the top half of the screen; then a few seconds will go by and its black. Doing anything will keep it locked even if i try typing it anyway. Please help me figure a way out to get my photos back so i can send the claimed Note 9 in the mail this evening. Thanks!

Do you have a USB-C - HDMI Cable or Adapter ?? That's the only way i can think of you getting access to your Note 9!

this is a great idea. Get access to the phones GUI, offload the pics to google drive or whatever else you have access to, profit. cant forget to profit...

Help needed: Strange issue when trying to turn on screen

Hi! My Galaxy Note 9 has recently started having a really strange issue.
When I press the power button and unlock it using my fingerprint, I can clearly hear the phone unlocking, but my screen stays perfectly black. When I press the power button again, it makes the stock "locking" noise that it makes. The little click.
If I don't relock the phone, it still can be used! I can actually click icons, accidentally send texts, etc. but no image....
Here's where it gets weird.
If I tap the screen two to four times and THEN press the power button, my screen turns on! I'm then able to use the phone like normal. Crazy!
However, for whatever reason I cannot use this trick when I get a phone call. So I just have to call people back.
Has anyone experienced this before? Do you have any tips to fix the problem? I have already tried restarting the phone, and powering it off and turning it back on. My last resort is a factory reset.
Welcome to XDA
May be a rootkit. If your running anything lower than Android 9, a factory reset may not purge it ie X-helper. The longer you wait the more damage malware can potentially do.
Delete Google account from phone and...
Nuke it, then reset your Google account password after factory reset.
If it persists, reflash rom. If it still persists it's hardware.
Two days ago I did click a link in a spam ad. And then yesterday the problem kicked in, so your suggestion has some pretty strong credibility in my mind. I'll take the actions you recommend. Thank you!
Maybe go with Brave browser in the future and add this modification to the new load. It globally blocks ads and some of the worst sites as well.

Question Vivo X70 Pro+ completely dead

Hi all, my phone (actually wife's) is a Vivo X70 Pro+ Chinese version.
One day when she was reading novel on the phone, it just freezed up and she tried to long press the power button to shut it down.
Aftwards, the phone just cannot turn on correctly, but just with different kinds of corrupted screen (screenshot for example)...
Just wonder if there is any method that I can try to recover it with aid of computer?
As there is no way that I can take it back to Mainland China for the warranty service...
Many thanks for any help/suggestion to be offered.

Where are you located? That COULD be a faulty / loose display connector. Hardware fix is probably necessary.

I'm in Hong Kong... Just wonder how the phone just sudden death when using...
I guess your best bet then would be to take it to a local repair shop or open it up yourself to check the display connector. What happens if you reboot the phone? Does it show the Vivo 5G logo? You can force reboot by holding volume down and the power button until you feel a vibration.

If you know people who are aware of the craft you can order the display from vivo official website and get it changed locally
