[Q] SGS4 with black screen not connecting using adb - Android Q&A, Help & Troubleshooting

My screen on my unrooted SGS4 is totally black after a glasschange that an idiot was supposed to make for me.
He failed. But the phone isnt dead !
The buttons is lit when I press Home or Power button, and the lightdiode is blinking blue as if I gave a message waiting.
If I connect it to a PC I can see the phone in Explorer, but when I click on it its emty...nothing to see.
I purchased a mhl-adapter that they said could show the screen on a TV using HDMI, but I get NO picture ...
I tried ADB 1.031 myself but seems it cant connect.
This is all I get...

[Q] Exclamation Mark When Powering On - Matrix One

I've recently searched high and low for a working solution to an issue I'm having with my Matrix One tablet. I'm getting an exclamation mark inside of a triangle, inside of a battery icon. The issue started after I let the battery completely die out. I can't get past that screen. When pressing power the battery icon shows up and the tablet shuts down a second later. I tried all button combinations to get into recovery, nothing worked. I've also tried charging the tablet, I've left it overnight a few times, and that hasn't helped.
There was one thing I managed to do, that was get the tablet to show up on my computer. I held down the update button with a needle and then held the power button until a blue light indicating the tablet was on showed up. The screen was black but my computer detected a new device. My computer didn't find any drivers for the tablet, so I went in search of them myself and couldn't find any. My tablet is A10 compatible, but none of the A10 drivers I found seem to work on my tablet when I go to manually update it through device manager, neither does the PDAnet method I found online.
I was able to find a recovery that works on my device, one that will allow me to reset my tablet, if I'm able to boot into recovery after I get it on my tablet. Now in order to even test the other recovery I need drivers for my device so ADB can detect it and I can push the recovery. My device is already rooted with Superuser updated to the latest build.
I'll add that I've even taken the liberty of opening up the tablet to see if I can disconnect the battery from the board to cut all power, as I've read that has helped other people, but I'm unable to do that because the batteries are connected by soldered red and black cables.
If anyone can be of assistance I'd really appreciate it, thanks in advance for any replies.
Still need some help with this... If you have any A10 drivers you can point me to I'll try them if I haven't already.

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 ,

Samsung Galaxy S6 Edge does not turn on or charge

Dear All,
all of a sudden, my Samsung Galaxy S6 Edge (SM-G925F) turned off yesterday and I haven't managed to turn it on since that. I've tried all of the button combinations (safe mode, recovery mode etc.) that most websites advise as solutions but my phone is still nothing more than an expensive brick.
I downloaded Odin, installed the Samsung drivers but when I connected my phone via USB there was not even a sound notification of my Windows PC which would notify me about a connected device. (Though I had never connected it to my PC before it turned off yesterday.)
The only visible effect I achieved (after pressing and holding a button combination I can't remember) is the blue notification LED which has been constantly shining since that.
What shall I do?
I'm begging you for any help.
Thanks,
Dave

Black screen issue, i can't restart the phone

Hi! I'd like some help.
I have a Samsung Galaxy S10e (SM-G970F).
The power button is faulty, I got it back from service yesterday, unfortunately it was not repaired because the device is rooted.
Before I handed it in for service, I was able to turn it on without the power button (download mode -> restart), but now the download mode is not available either.
And it doesn't indicate charging either, the display is completely black at all times.
Yesterday the computer recognized it as a drive, but it showed only one TWRP folder. Today, unfortunately, the computer does not even recognize it, nothing happens when the usb cable is connected.
Is it possible that the device has remained in some service mode?
Somehow I would have to reboot or get into download mode, I just don’t know how..
So now:
The display is completely dark.
It does not respond to buttons.
The power button is broken.
It does not indicate charging.
The download mode does not start. (volmune down + bixby button & connect usb data cable -> nothing happens.)
The computer does not indicate a usb connection.
The adb doesn't see either: error '(null)' not found.
What can I do?
To me it seems phone's boot-loader is broken: a working boot-loader would start Android's "init" process what automatically starts ADB on phone, if USB-debugging got enabled on phone, what in turn would make the phone accessable via USB.

Thanks for the reply.
However, I have new news about the device.
I realized that the device itself works, only the display is always dark.
I disassembled, unplugged the battery from the motherboard, and switched back to download mode and Odin recognized it.
I managed to update the software on it, the device restarted fine, only the display is completely dark.
The computer already recognizes it, I can give a command via adb, and I can hear the volume button when pressed.
The only problem is that there is no picture on the display.
I reconnected the display connector to the motherboard, but that wasn't the problem.
When the power is off, the display does not indicate that the charger is connected.
Does anyone have any idea what else I can do?

Your hardware is faulty, replace the screen.

Unbrick Ulefone S10 Pro

Evening all!
I managed to brick an Ulefone S10 Pro by trying to flash a rom onto it which ended in a brief error message and then the screen went black.
Since then, it wont boot up. There is just a black screen and it vibrates briefly as if it's starting up but then nothing, before repeating ad infinitum.
When I connect it to a computer, the computer makes the connection sound, then a few seconds later, the disconnection sound. Nothing is shown on the phone nor the PC at this time.
I have no clue what to do as it doesnt stay connected to the computer long enough to be recognised before disconnecting and nothing appears on the phone screen. Ive tried disconnecting the battery and connecting to the computer without it but the same thing happens
Haylp! :laugh:
Thanks
