K20 pro Black screen issue after installing EU ROM (worked fine when suddenly turned) - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi folks,
Appreciate your help on this. I've recently change the chinesse rom on the k20 pro after unlocking the bootloader (i've done this several times in the past)
It was perfectly working, i was setting the miui up and put my google account when suddenly screen turned black with no response.
Tried pressing volume up and power keys for minutes, volume dorn and power keys... power and nothing. Still black.
THe thing is every time i do that, vibration sound and led work but no touchscreen response.
Additional information, i could not add my MI ACCOUNT and still can access the phone over fastboot (writing .\fastboot devices in the ADB FASTBOOT Powershell).
Would be depply thank you if you can support me!!

i think display is dead.did u find any solution?

Have you tried re-flashing stock Chinese rom over fastboot?

itbshould force reboot when you are pressing pwer button about 5-10s
if you feel startup vibration and if still not bring up screen then;
Preess volume down+power button untill you feed starup vibration
after that connect your device to pc and see if device recognized.
if recognied go to mi flash and select clean all.
browse and select fastboot rom. flash.
if it doesnt work then you should try edl method..

Le2 x520 no screen after unbrick

Hi
Hi all,
I've used this thread to unbrick a Leeco Le 2 (x520).
The flash itself went like a charm, however, after disconnecting the cable and pressing the power button to reboot, the screen remains black.
When I short press the power button I can hear a sound and vibration, but that's it.
I'm stuck, even more so than before.
Is there anyone who can help me with this issue please?
Thanks in advance!
PS: I've also posted this question Thursday in the thread itself.
hello, did you solve the problem? I have the same situation. If you solve the problem, please write to the mail [email protected]
I've also same issue, please tell me if you get rid of this.

Hi
I have same issue. Its looks like phone is turned on but my screen is black. I cant connect with adb cos i flashed fresh stock rom and with black screen i cant turn on debuging usb or unlock.(i can\t flash twrp so i cant flash new custom rom) Is there a way to flash custom rom with stock flasing tools like flashone or qfil, or is there a way to control my phone from computer without needing android screen(i can\t give any permission to new apps cos it new stock rom and my screen is black )
Solved - No Display after Flash
I know this is a old thread, but still i am posting this because u never know who might need it...
Guys i was having similar issue. After flashing Le2 with QFIL, I was getting no display. However my phone was somewhat on and making bleep sound when power key was pressed. Do this if you have similar problem:
1. Download this firmware:
https://drive.google.com/file/d/136X8jKA5eJRkyQ3Fi2f1r6qNkLXAG8io/view?usp=sharing
2. Flash it with QFIL/Miracle box/UMT whatever u feel like.
3. Hold Vol+ and Power button and goto Recovery. TWRP recovery will boot.
4. Now put any rom (i used latest LOS nightly) in it by using MTP from PC and flash it.
(Optional step: if u want to use official firmware It may happen that u get stuck at LeEco boot screen, only if u get stuck, then flash the kernel inside the zip and it will boot normally.)
5. ENJOY ^_^
If this helped, you know what u have to do :angel:

Phone hard bricked??

So I was trying to restore back to stock firmware with miflash, but for some reason it messed up and now wont boot at all.
Yes ive tried force rebooting it, plugging it in my pc, nothing will work. i say a notification led that blinks every like 30 seconds.
its just stuck at a black screen, i left it off the charger to drain the battery but im not sure if it still has battery or not.

You've tried all hardware button press to boot in fastboot or twrp?

Yes it wont go into fastboot either.
So to be clear, holding down power button for 5 seconds does nothing at all? No vibration, no mi.com logo, nothing?

Correct I tried holding it for like 30-40 seconds and nothing. all i see is the led blinking and nothing else
OK, try this :-
-install JDK 8
-download and run https://github.com/Szaki/XiaomiADBFastbootTools
-select fastboot tab
-Hold down power button again, see if anything pops up in the left box
If it does, then you can download the latest global / eea rom and flash it from there. If nothing comes up, we'll see what else we can do

Mi A2 black screen, cant turn on!

Hi guys, my Mi A2 wont turn on anymore. I was downloading PubG mobile and then installed it and while it was being installed my phone was freezing. The screen then dimmed and then turned black. I then tried to reset it (holding power button and volume up/down, only holding power button... i tried almost every combination) without success. When i plug in the charger there is no vibration and no led indication. Back at home i tried to plug in the computer. I hear the sound of the pc which indicates that a usb device was connected but nothing more. When i hold the power button while plugged at the pc, after 12 or so seconds the sound of usb disconnection and shortly after of usb connection is coming. The phone was fully charged.
I use rootet pixel experience 10 with unlocked bootloader.
I dont know what to do now. Can someone help me? And apologies for my bad english.
Best regards

So i downloaded the MiFlash tool and tried to flash stock firmware but i got an error message. Does someone know what it means?
I think you should try to enter the phone in EDL (maybe with the test point method) and then try to flash the stock firmware as you did.
Does the phone notification LED turns on when you plug in the deviceto the PC?

your phone entered edl mode ... probably due to update ota...do you have a jasmine to wayne conversion ...did you flash firmware package ?
anyway you cam flash a rom but probably the error in miflash is bevause you have ARB ..look for ARB4 rom and flash that to boot
if you didn't convert or have ARB4 or didn't update ota or something like that you probably have some broken hardware in phone and must replace some pieces and miflash gives errors because it cant fix hardware

it happens with phone, when either one of button is pressed, not by us, its or we can say button stick in pressing mode from strip. in your case, its due to pressed button of volume down. so whenever you switch on it goes to fastboot.
Thanks for your kind reply bro.
How to solve the problem bro any ideas that I can do.
Thanks and regards

"guide" went wrong

Updated regulary redmi note 9 to miui 13. Phone started freezing, restarting etc. So I wanted to downgrade to 12.5 miui and followed this:
. With renaming file, It reseted but there wasnt recovery mode to data wipe phone. Now It keeps showing only redmi logo for like 20sec then screen goes black and again to redmi logo. I waited for battery to be empty and the moment I plug-in it goes same routine. Power off button do nothing. Volume down+power nothing also. Any combination wont work. Usb cable in PC wont recognize it.
