Help, blank screen and unable to boot - Xiaomi Mi Pad 4 Questions & Answers

I was searching for a solution for my contact sync issue and I needed to reboot. After pressing reboot, the screen goes blank and I cannot boot again. Volume up + power doesn't work. Plug in power and the light didn't turn on. Even try to hit the tiny hole that looks like reset and that didn't work with. Help!
I am on official miui 9 with Google installer

Did you hold the power button for a longer time?

Yes, try holding the power button for some time. One time, after fastboot, it took around 90 seconds to power up.

there's a tiny hole that looks like a reset ????
did you poke the mic hole?

Hi Rioru, did you ever find a solution to your issue. After charging last night, suddenly I had exactly the same error. Which means I cannot boot the tablet, Power+Volume UP does not respond, charging LED not responding and after connecting to a PC I cannot not establish an ADB connection.
Thanks!

Hi, I think you're quoting the wrong person here. It's not me, it's spx2000 had this problem.

I have two...1st mi pad 4 flashed many ROMs looking....2nd mi pad 4 on first flash device will no longer boot. PC with miflash starts flash but errors on com port. I have tried cables and different ports. Need help . Black screen
Tablet is seen in win as Qualcomm....miflash sees device as I try different USB ....flash always errors unable to read comm port xxx. Not sure what to try next.

Same issue here, MiPad4LTE. Mine just died while playing mobile legends. Power wont turn on. Even when charger is plugged, LED won't light.

Tablet won't power on anymore.

I was using my tablet while finishing charging. I was about 95%. Suddenly it just went black and won't turn back on. Any ideas? I've tried holding the power button with no results. Is there a special reset or something?
Anyone else have this issue or things I can try to fix it?

Have you tried PC Companion? Download it for Windows then try to locate for emergency repair. It will show you instructions of how to put your tablet in flash mode.

I haven't tried that specifically, but would it not fail if the light didn't even go on when plugged in, and my pc doesn't even read it as connected?

Not really, for example in some samsung devices even if the device wont turn on the a JIG plug was able to put the phone on download mode, something very similar to flash mode on the xperia mobiles.
So i guess the last thing you can try is to put the tablet in flash mode, you can download a FTF file with the firmware compatible with your device, and download flashtool from: Click here to download and then put your tablet on flash mode. I guess you will need first the drivers Click here to see drivers and after you install the drivers, just open flash tool press the vol down key and connect the usb cable to the tablet, and if you see that flashtool or maybe windows recognizes your tablet you may have luck to restore it.
So if you get it into flash mode, then just flash the FTF and let's see what happens.
Let me know.
I will give it a test this evening or tomorrow - thanks! I will post back if it works.
PC Companion doesn't detect the tablet, nor does my PC at all in device manager. It doesn't respond like anything is plugged in, but it did before.
Flashtool comes up with nothing either - once again doesn't even acknowledge anything is plugged in.
Thanks for the suggestions, though.

I read your issue. Read my first post again - yours is simply a crash. Mine does not charge, has no power LED, and is completely unresponsive. No recovery button combination or anything works - yours turns on and responds to things.
so when you try vol up and power button do you not see the white led flash once then a couple seconds later three times? if it does it means your tablet can still be put into flash mode with some perseverance.
Edit: you could try sony mobiles flash tool called Emma which has its own way of entering flash mode (think you hold vol down and plug the usb cable in the computer) and see if that program can detect your tablet but you can use the instructions provided on their website if your unsure what to do.
same sitation
I have the same problem with my tablet. I watched stock photos in album and then display switched off. And that's the end.
Nothing happens when I try to power on, reboot or restore with Companion. Computer doesn' detect device. The same situation with Emma and flashtool.
I used my new-bought tablet only for 15 minutes)))
Mine ended up needing replacing due to a fried mainboard. Did you leave yours plugged in overnight?
Ok something strange happen to the tab I never had problem before I left the headphone plugged in a press the power button to close the screen (I always do that) when I try to use the tab there was nothing on screen double tab the screen nothing, hold the power button nothing put the tab in the cradle nothing the led was not turning on but the usb cable direct to the pc and than the charger nothing. I press the volume up and power button the tab led blink and was able to restart the tab. ??????????
Same thing just happened to me. Power button would not turn on the Z. LED would not turn on when charged. Did a hard reset and it came back on. Model: SGP312.

Pc companion will not work in thta situation cause it needs the device to be powered on...
In that case have you try the SUS http:/sonymobile.com/gb/tools/update-service/
Just follow the instructions and you will be fine
It will erase the entire internal memory though, sd is fine..

Chinese Tablet won't start

I have problems with my Allwiner A13B tablet. It wont start at all. I had a bootloop problem, so i flashed the tablet wiht LiveSuit. After the flash everything was ok, only the touch was working opposit but i've found a fix for that. I was cheking the options to see if all of the others features are fine, but i didnt had much of a battery and the battery died and tablet turned off. I've tried to turned on ever since but with no luck. The combination of the buttons (VOL + & PWR) won't work. I've tried to hold for 30 sec the PWR buton and plugged in then press the power button for 3 sec to try to start the tablet but nothing happends, not even with the reset button in the little hole. The blue LED light was working when i plugged but 4 hours later it stopped. I just leaved my tablet not plugged in for 2 hours then i plugged in and the light start to work again but 2 hours later it stopped. When i plug in the device in my pc and try to launch LiveSuit the update process starts but after few second fails and the PC says that the device i've connected has a malfunction. Please help me if you can.
come on guys help me please

[Q] Phone will not tuen back on

In sum, earlier today I was using my phone with no problems-- calls, texts, using apps etc. I went to 'close my screen' when I was done using it and I realized the side power/lock screen button was not working and my screen was not responding when I wanted to lock it. I removed the battery hoping it would reset the phone and fix what was wrong but now my phone will not turn back on. I plugged the phone into the wall for at least 30 minutes as well as plugging it in the computer for quite some time. No response from the phone at all. (no charging icon, computer is not detecting the usb cable when plugged into computer, etc.)I also held the buttons down to try to power on as well.
I was wondering if there was a way to fix this problem, or somehow retrieve files (mainly pictures) from the phone,
Thank you for your help. Any feedback will be greatly appreciated.

I attempted to hold volume down, power and home buttons but the phone did not respond. The computer is also not recognizing it while plugged in via usb. The button does not seem to be 'stuck' as i can still hear a slight clicking sound when I press it.
Try removing the battery and hold power down for 30 seconds and then try installing the battery again.
Try that ^
maybe a jig might help

Mi Pad 1 not starting how so ever. Please help!

Hi there,
I bought this MiPad about 4 months ago and it was all working properly till yesterday. And all of a sudden, I saw the fast boot screen showing up on the screen. I was clueless as why that screen was showing up without me doing anything. I didn't know what to do and pressed power button (maybe that was the mistake I did). Now the device is turned off and not turning on at all. I tried many ways to turn it on, but failed till now. I have tried -
- Holding the Power button for quite a while.
- Holding a combination of Volume buttons and Power button.
- Charging it overnight and trying the above two steps. (though connected to the charger, no notification lights showed up)
- When searching for solutions, came across this thread in some forum. Tried this as well, but no results. (http://forum.xda-developers.com/ ... ve-totally-t3417604)
When I connect and disconnect the device to my laptop through USB cable, I can hear the Windows beep sound, but does not detect it (I mean, it won't be displayed in either MiFlash, MiPCSuite tools or in the Windows file explorer).
If anybody has a solution for this, please help. Thanks.

HELPP! BRICKED XPERIA Z ULTRA, Wont turn on!

Hello everyone,
i got a problem with my z ultra and have tried looking similar problem on this forum but none of the solution seems working.
Please note that i have a stock phone, never did anything to it including unlocking rooting etc as i have no idea what it is, just casual usage.
So the problem occured when i tried to move an apps from sd card to my internal storage, and then my phone freezed midways,
the phone went unresponsive just showing the freezing screen.
Then i pushed the red button near the sim tray hoping the phone will reboot as i had similar problem before, and thought that it was just another minor problem and it worked.
But this time after pushing the red button the phone wont reboot again after i try to turn it on again using the power button, only a vibration but the screen showed no display whatsoever.
Ive been looking a solution on this forum with similar problem and there was a suggestion to connect the phone to power source and push the power and + vol together but there was only vibration thrice without indication of my problem has been solved.
Ive also tried a solution on youtube to disconnect the power cable, charge it to power source, wait for the Red LED to blink and reconnect the power cable again but it wasnt working.
Long story short after trying several method now my phone only blinking Red LED 3 times when i tried to turn it on, i tried to charge it to full but the Red LED keeps showing on even after i discharged it, so i had to push the power and + vol button to turn it off.
I suspect that my phone is hardbricked looking at the symptomps
Please anybody here could help me to fix it?
It's probably not hard-bricked.
Try this,
1, connect your USB cable to PC (without phone connected to it )
2, press volume up button and then plug in the usb cable to your phone
3, if light goes blue colour then you are back in business and you can still revive your phone
step 3 if successfull means your phone is up with fastboot mode and you can upload a recovery via flashtool
let me know your results ,
