[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!

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

Can you phone enter flashmode ? Does any LED indicator shows up when holding Volume +/- whilst connecting cable in PC (USB)?

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

[SM-T510/T515] 2019 Galaxy Tab A 10.1 Hard Resets

Here's a quick reference for how to reboot and reset your 2019 Galaxy Tab A 10.1 (SM-T510/T515) using the hardware buttons:
Force restart:
- If your device is frozen and unresponsive, press and hold the Volume Down + Power keys simultaneously for more than 7 seconds to restart it.
Boot to Recovery Mode:
- Power off the device
- Press and hold the Volume Up + Power keys at the same time.
- Release both keys when you see Recovery Mode.
Boot to Download Mode:
- Disconnect the USB cable
- Power off the device
- Press and hold the Volume Down + Volume Up keys
- Insert the USB cable
Boot to Safe Mode:
- Power off the device
- Press and hold the Power key.
- When the boot logo appears, release the Power key and then press and hold the Volume Down key.
- Continue to hold the Volume Down key until the device finishes restarting.
- Safe Mode will display in the bottom left corner of the screen.
Since there is no Bixby button, these combinations are different than the Galaxy S10. If you know of additional combinations, please contribute to the discussion below and I'll consolidate here.

If there’s no response on your device or you're stuck in a boot loop, then you might need to wait for the battery to drain. The 2019 Galaxy Tab A 10.1 has a non-removable battery pack, so disconnecting that isn't an option. Hopefully, the system reverts to its normal function with a cold boot. This can take time if the battery has high charge left at time of failure. Depending on how fast your battery drains, this can mean waiting for a few hours to several days.
UPDATE: With the right timing, you can break out of a boot loop into Download Mode...but it's tricky:
Insert USB Type C cable connected to your PC
Press and hold the Power and Volume Down keys for exactly 7 seconds (hard reset)
Release the Power key and press and hold both Volume Up & Down keys (enter Download Mode)
If you don't see the blue bootloader unlock warning screen, keep repeating the above two steps
The trick here is that you're trying to time your switch to the Download Mode keys for the exact moment the hard reset takes effect. If you see the boot logo while still holding the first key combination, it's too late. If you switch too early, you won't trigger the hard reset.

I've had to hold down both volume up and volume down while plugging in usb to get the unlock screen to populate. Canadian Wifi variant.

Thanks, that was an error in my initial post. I was figuring these out by trial and error, but it turns out that our hard resets are basically the same as for the Galaxy M30, which also uses the Exynos 7904 SoC and has no Bixby key.

UPDATE: Also the same as for the Galaxy A30 and some others.

Yes, I did the same way
US version
1. Enable OEM Unlock
2. Turn the tablet off and unplug the cable
3. Press and hold both volume up and volume down buttons and plug USB cable to host computer
4. You will get wipe screen. Long press volume up to unlock the bootloader.
Now I have to find matching ROM and patch the boot.img and flash.
I believe you have to disable Vault Keeper to keep root intact.

Brand new out the box 11am this morning.
Opened the parcel cool no damage. Powered up fine, had a mess with it, no problems check the speakers were fine and no issues plugged it on charge to 100% took it off and left it for an hour or so, went back to it and physically used it to use Facebook and play candy crush cool no problems. Took a few photos and no problems again. Put it on the side still on near 90% and went back to it 30 minutes later completely off and won’t turn back on, tried charging it nothing no sign of life, tried rebooting it and still nothing. Please tell me that this is not the end and I need to get a replacement... ?*

Have you tried getting into download mode? Or recovery for that matter.

I’ve not even been able to get it back on, I’ve attemp a reboot countless of times and still nothing rectifys it. I spoke with Samsung they feel it’s a major fault with the tablet and have told me to request a replacement from my provider or even a refund.

Forgot pattern password, unable to power 510 Tab A off since pattern password is required. How to wipe tab or reset to factory without powering off?

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...
