Hi, I installed a new battery on my Mipad 2 tablet running MIUI. It didn't start, No led light, No fastboot, no recovery mode. Out of desperation i searched online and found a solution relating to short circuit on a mi pad 1. Many have reported to have succeeded in re flashing their mi pad 1 after the successful short circuit by placing a copper wire between the sd card slot. It eventually got detected on windows after disabling driver signature verification turned off.
However i tried it on Mipad 2 but got no response whether through USB or MIFlash tool of Xiaomi. Sometimes leaving the tablet just like that for days and then just pressing the power button for 3-5 seconds, a blinking red light appears on led. Thats it. Nothing more.
Can anyone help me to do the short circuit thing properly. I feel im close to finding a solution.
Can u share photo of tab with back panel opened? With exposed motherboard?
You can try this if u want...
Disconnect the battery.
Connect the pins or short them, I mean.
Connect the tab while pins are in shorted connection.
Then connect the battery.
This had worked with my mi pad for which flashing wasn't going through. Mi flash used to give error while flashing I guess.
Try it if nothing else is working. At your own risk.

I have this phne for 2-3 weeks and it never run out of battery completely. Yesterday it did and when i plugged the charger it opened and it got stuck in the clock screen. No buttons are responding only the hard reset (power button and the middle one). The screen turns on and off every one minute. It is a mess...any help is appreciated!
Solved: Thank you guys for helping. I found that the solution was to download the Update Service from SE and follow EXACTLY the steps it mentions.
Steps:
1 Deactivate the phone for 30 secs. (in this case unplug the battery once it could not close normally)
2 plug the micro USB in the phone and then the USB to the PC
3 Before plugging the USB to the pc press the back button and hold it for as it takes. it takes a while. the the update service will start formating your software and it will be as new...notice that what the sd card contrains isn't deleted
realy ther is noone with the same problem? i start to worry. please could anyone say any opinion?
Hello,
try to start your phone in save mode and then deinstall your 3. party apps.
I think the failture comes from an app.
an app could also be the reason for a verly long boot time.
her some info's about the save mode: androinica.com/2010/08/06/how-to-activate-android%E2%80%99s-safe-mode-to-get-out-of-a-force-close-loop/
hope this can help you with your problem.
My suggestion to you would be to take it back to the place where you bought it and tell them to fix it... if it's only 2-3 weeks old they shouldn't argue.
Best XDA-Devs,
I think I may have done something REALLY stupid.
Today I possibly hard bricked my phone.
How? You may ask.
Well, I was looking into installing a custom recovery and found out I had to unlock the bootloader first. So I googled how to unlock the bootloader and found a XDA thread about it.
I followed the steps and tried to install the aboot.img file attached to the thread.
I opened up CMD and began replacing the stock aboot file with my aboot4.img file (I renamed the attached aboot.img to aboot4.img because I thought this was necessary).
I then rebooted my phone and BOOM nothing works now.
I can't turn on the phone, I can't get the phone into recovery and I can't even get the phone into download mode.
If someone knows how to fix this (if it's possible at all), please post it.
If you need any more information just ask.
Regards,
Thomas.

Thank you very much for your reply!
I'm going to try this and will report if it has worked.
Regards,
Thomas.
It isn't working for me yet.
I'm now draining my battery until it's at 0% and retrying this instruction.
Again I'll report if it has worked.
Regards,
Thomas.
I've been trying to get this to work for a couple of hours now. However there's no success yet.
I'm not giving up yet!
Any ideas?
Regards,
Thomas.
I did it!!!
I finally got into download mode!!!
After a lot of just tinkering around with this guide here, I was finally able to boot into download mode.
This is how I did it (this may not work for everyone):
1. Completely drain your battery. First I placed my battery in a LG L90. I ran as much tasks and services as possible on this device. When the battery was down to about 2% the phone automatically turned off. It was at 2% and 0% so I had to come up with something else. I got my battery and an LED. I held the LED to the + end - poles and waited until the LED turned off (the battery was now completely drained).
2. Place the battery back in your phone.
3. Press the on/off button. If you see the 0% battery icon go to step 4. If you don't see anything keep trying until you see the screen. If you still can't see the screen just give it some time and try it again later (if you want you can check if your battery is empty with the LED method).
4. Press the on/off button again and at the moment you see the 0% battery screen hold down the volume up button and plug your usb cable into your phone (the usb cable should already be connected to your computer) while holding the volume up button.
5. If nothing happens, try again. If you see the screen that tells you to keep holding that volume up button, you should be holding that button.
6. If you've reached the download mode screen you may sing your happy song now (I did).
7. Now flash your kdz (if you want me to post a how-to link, just ask).
8. Post your happy comment in this thread because you finally unbricked your phone!
I did this on my LG D620 and successfully unbricked my phone.
Regards,
Thomas.

Thanks for your helpfull messages. This method is worked for my LG G2 mini D620r. It is a simple way to unbrick/unHARDbrick to your phone, if you can find a way to finish your battery. This is the same subject here. I want to add somethings.
I tried to unlock my bootloader too. But my phone is bricked so my phone
* cant open; only black screen.
* cant connect to pc; pc cant see my phone so doesnt work adb/fastboot mode.
* cant reboot recovery or download mode.
! but my phone shows an empty battery icon warning, if I remove the battery and connect my phone to charger.
When I read this i didnt believe this will works for me. But when i found the same method in this thread, i give it a try, and it WORKED for me too
1.a find a cable; short and thin, find something which works 1 AA/AAA or 2 AA/AAA; it may be a flashlight/torch or a toy or something like that.
1b. find a good condition usb data cable.
2. a led like that.. You can find it easy in your home. I used my old battery charger led or you can buy it.
3. uninstall all LG programs; LG USB driver, LG pc suite, LG *.* (reboot).
4. download and reinstall only LG-Mobile-Usb Driver(reboot). (maybe 3 and 4 are not necessary but i did)
5. remove your battery from phone, and connect it to your torch(flashlight, toy) with a cable. Yo can see +, - symbol on your battery and torch. Wait until your torch doesnt give light.
6. connect your battery to led and wait until led turn off. It maybe take long time, be patient.
7. put your battery on phone and push power button; if you cant see anything it is normal because your battery is completly drain or if you see an empty battery icon it is normal again because your battery is about %0, so 2 possible things but both of them are normal and enough/good.
8. connect your usb cable to your pc.
9. while pressing volume + plug your phone to usb cable and hold on(~10second).
10. If nothing happened dont worry, unplug your phone and go 9. (read 11)
11. If you tried more than five go 6 and keep try. (because your battery now ~%1, you should drain it again)
12. If you see the screen that tells you to keep holding that volume up button, you should be holding that button.
13. If you've reached the download mode screen you may sing your happy song now (I did too).
14. Now flash your kdz (if you want me to post a how-to link, just ask).
dont worry it will works. try again and again and agian... I tried more than 5. Good luck.
Thanks again, Thomas and panagiotisden2.

D618 Solution new procedure.
Hello. This procedure solved my problem with D618: youtube.com/watch?v=FXs7NAaTz4M&t=0s
Hi guys,
My screen recently died. Before fixing it at a specialized shop, I want to retrieve the data from the phone. Sadly the phone is pattern-locked and until I unlock it I can't access the data when I connect it to my PC. The screen is essentially dead. The image is almost totally black except for small layer in left top corner and the touch sensor is unresponsive, but other than that the phone works and receives notifications and so on.
USB Debugging mode isn't active on the phone and thus I can't replicate the screen of the phone on my PC through software alone, when I connect it via micro-USB. I also didn't think of this problem in advance and I'm not registered on Sony's FindMyMobile or any similar apps.
I tried using a HDMI-MHL adapter and I confirmed that the phone is indeed working because I'm able to get the phone screen's image on my TV. The problem is I can't actually interact with the phone because as I said earlier the touch sensor is not working.
The HDMI-MHL adapter I've used also seems to have a micro-USB port but that seems to work for power only. If I connect a USB-OTG cable on it and connect a USB mouse to it I get image but no mouse. If I connect the USB-OTG and the mouse, alone, I get a mouse cursor but I can't see what I'm doing (phone vibrates as I 'try' and draw the unlock-pattern blindly).
So, Sony Xperia Z3 Compact screen is dead, I wanna connect my Xperia to my TV via HDMI AND use a mouse at the same time to control my phone. Is this possible_
I also thought of another option... go to recovery mode and flash a zip that removes lock. I thought of trying step by step (switch keyboard and TV al the time just to get at point where I can find zip file and flash it). Unfortunately in recovery mode the phone does not allow to stream to TV. It only works when phone is after SIM lock.
Two additions: by removing and re-installing ADB on my laptop my phone is unauthorized. Only a matter of clicking on yes/allow on phone but that's not possible and TWRP 3.1.1-0 is installed.
Anyone any clue? I know I ask a lot but I'm searching the internetz for 2 days now and I'm devistated.
THNX a great bunch!!!
ciao
Valentijm
PS Copy/paste a part of the text from a guy from the internet who had exactly the same problem as I did but his thread ended a few months ago without result.
Just 30 minutes after my post I magically had all the dots correct and that blind!!! So turned on USB debugging and got rid of lock pattern. It was a nice three days of my life Guess there was no solution than getting lucky like I did or screen replacement and getting all your data removed.
ciao
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.
I've been stalking this forum for a few years now, from back before all the pop ups, but for the first time i'm stumped. Here's the rundown: i broke my pixel 6. not terribly heartbroken, the phone is ****, everything it does "well" is only moderate on any other phone i've owned.... sorry, digression. Anyway, screen is completely black and unresponsive to touch. screen is locked with 6 digit pin. I know the pin. but i cant enter it because the unresponsive screen. Phone gives haptic feedback when a wireless mouse is plugged into a multi port adapter, which i bought intending to plug the phone into an hdmi port... but back to the pixel 6 being a ****ty phone, i have to install an app to do so, since the phone doesn't do it natively.....which i cant do, because it seems that while usb debugging may be on (adb detects the phone) i cant authorize the computer.... even though ive done it a hundred times, always clicking "always allow from device" sorry, digression again. i just want to get my **** off of this phone. guys at cell phone store are either incapable or incompetent, because they say they need touchscreen access. i have otg adapter, multiport adapter, wireless keyboard/mouse....can anyone help me?
EDIT broken phone has to go back to the insurance company in....6 days

sure would, hell, it does. except that im still signed in on the old phone. and since that is the case, google keeps asking me to verify my identity via broken phone. and trying to do account recovery results in an email explaining that im signed in on another device, and if i want to change my password, i can do so on that device

you see my dilemma?
You may be able to project your screen with a wired dock (see https://support.google.com/pixelphone/answer/2865484?hl=en). By following the directions and begging for or borrowing a USB-C dock from someone, you should be able to get your stuff off your device, especially as you can connect a mouse to the dock if touch doesn't work.
The other alternative that may work for you is to go into fastboot (long press power to shut off the device, then press and hold volume down while pressing and holding power) and use ADB to backup your device, including the storage. See https://www.technipages.com/how-to-backup-your-entire-android-device for details, and pay attention to the -shared flag.
