Question Black Screen on Mi 11 - Xiaomi Mi 11

Hi everyone,
I really need some help with my Mi 11. I was on FB Messenger when the screen suddenly shut off on its own. I've tried a bunch of stuff already but the screen refuses to turn back on, though I think the phone might still be on: I have Whatsapp Web on my computer and I can still send/receive messages: according to Whatsapp, the application doesn't work if your phone is off or does not have an internet connection. I've tried:
charging the phone
pressing and holding the power button for >30s
pressing and holding the power button and volume up for >30s
pressing and holding the power button and volume down for >30s
pressing and holding all three buttons for >30s
plugging the phone into my computer(computer did not recognize that the device was plugged in)
and after all of these, the phone still hasn't turned back on. Does anyone have any ideas as to how I might be able to fix it?

Do you have CN or global version? Was the device hot?

(CAN I )Power on without a power button?

Hello, well as of yesterday my N7000's power button started acting up, first i got lots of sudden reboots (probably the 8-second powerbutton hardware reboot) and a few hours later my power button stopped working al-togetter.
I've seen some youtube videos where people with the same defect-powerbutton (tho on another samsung device) show how to turn on their device by plugging it in the usb charger and emediatly press volume down+ the home button.
My device is still turned on but it'd be a bit tricky to try that out myself.
I am curious if that works on our devices too, if anyone could test this method; thank you so much.
Any other methods/advice is very welcome
Kind regards.
(Device is running android 4.4.4: Omnirom)
try this (works for me) : place battery in the phone, hold (and keep held) vol - button and insert usb.. it should take you to the warning screen before download mode, where you can press vol - to reboot.

[Q] How to switch off phone with broken screen?

Dear Xiaomi Mi3 users,
I'm sorry if this question has been asked before.
Basically my touch screen is totally cracked and unresponsive. I need to replace my screen. I ordered a screen and repair kit from China, and it has arrived. However the instructions say that I should switch off my phone before attempting to replace the screen. The problem is, the screened is cracked and I can't press any buttons. Holding the power button for a long time simply reboots my phone, it doesn't shut it down.
What should I do???
Thanks!!

1) when your phone reboots at that time press the volume up button , the phone will enter into recovery mode and from there you can turn of your phone without even touching your screen
2) you can plug in a PC Mouse t your phone sing a OTG cable and can access all the functions without touching the screen

After restarting, when you see the MI LOGO, hold power & volume down button, it will execute the fastboot and just wait for a second your phone will automatically shuts off.

Is it not "Volume Up" and "Power Button"? iso just "Volume Up" button.
I just had to do this too.
Hold power button for ten seconds to reboot.
Immediately switch to power + volume up to get to fastboot
But the fastboot screen does not automatically shut down. And holding down the power button for ten seconds reboots again. And because of my broken screen, i can't see the fastboot menu.
In the end I plugged it into a computer, installed adb, and did adb shell and adb reboot -p (-p for poweroff)
Now, back to replacing my screen, being very careful not to press the power button this time.
Hi,
Today I had the same problem. Xiaomi Redmi 4x with broken screnn and I could not shut it down to replace its display. After a few tries I found the solution.
Just press Power button and Volume Down and DON'T RELEASE THEM UNTIL THE SMARTPHONE IS COMPLETLEY SHUTDOWN. After about 8 seconds the smartphone will reset . Don't release the Power and Volume Down buttons , wait and the smartphone will boot again in another mode. Continue to keep both buttons pressed and after about 10-15 seconds it will really shutdown.
Good luck!

fastboot... Help

I've been charging the tablet for 4 hours. It still has a black screen that says fast boot in small letters. This didn't happen with the other one I purchased.
Does anyone have any advice? I want to give it to my daughter tomorrow!
Help!
If you've not been doing anything with it connected to a computer to install things I think you've accidentally pressed volume down when pressing the power button to turn it on.
If so press the power button until it turns off and then turn it back on with hands away from volume controls.
Hopefully just that

please help me.. black screen of death

Hi, please help me I really don't know where else to ask.
While I was using my P20 Pro for watching youtube, the phone suddenly went unresponsive. Being confuse I press the power button, so screen went dark and then I tried to restart by holding power button. But it never restart and never get to see the boot logo.
I tried what it says in the video, to hold Volume Up + Power or Volume Down + Power, but none of this worked. As in I never even get to see the boot logo. the youtube video title: "Huawei Mate 20/30 Pro Fixed: Black Screen / Frozen / Won't Restart / Won't Turn On" by WorldofTech
The weirdest thing my phone keeps vibrating every 10 or 20 seconds. Is this what you called boot loop?
FYI, I didn't try to do any root or flashing or that sorts. Anyone can help me?
To enter in recovery mode, your device must be turned off. If the device is vibrating every 10 seconds it is because it is not off. To turn it off, you must press and hold the power button for at least 20 or 30 seconds. Once it is completely off, by pressing the volume up and power buttons simultaneously for some second, until you can see the logo, you will be able to enter in recovery mode and do a hard reset.
You can also use another method according this link...

Is my ASUS ROG Phone 3 bricked? Screen doesn't turn on

Could someone point me into a direction what exactly the problem is? I have used this phone on unofficial LineageOS 18.1 for a few months but suddently after dropping it from not all to high the screen displayed lines and colors similar to those that you see when you drop your phone into water (there was no water contact and the phone didn't fall that great of a distance, maybe like 1 meter/ 3ft).
My first guess is that the screen is broken, but I tried using ADB to extract some files still on the device but was unable to, especially I can't boot into fastboot or recovery it seems...
When pressing the power button the phone vibrates
Pressing the power button and volume down key reboots the phone (as seen on PC). Holding them down a long time shuts the device off or something. it can only be turned back on when plugged in.
I tried all possible button combinations to enter fastboot or EDL but nothing seems to work (Power + Volume Up / Volume Up + Volume Down while connecting to a PC with USB 2.0).
On my PC the device shows up as "MTP USB Device", everytime, not sure if I'm doing the EDL thing wrong...
EDIT: After leaving the device for a day, it suddenly started to vibrate and repeat the sound I guess plays when battery is low, over and over again in an increasing volume. The volume buttons had no effect as did the power button until it stopped and then didn't respond anymore. After plugging it in again it was back to vibrating once after i pressed the power button. What mode is this??
Any help would be greatly appreciated, not sure if it is even bricked but it seems off that I can't enter fastboot or anything else (like EDL), thanks!
