The phone responds to nothing. Screen does't turn on, nothing.
Device manager keeps refreshing, I assume it understands the device is connected?
What can I do?

i had this error says application has stopped working (something like that), so i clicked OK. but few seconds later the error pop up again and again, and the phone is getting very hot. so i shutdown the phone, and it wont turn it back on. No sign of life. cant get into recovery or bootloader. when i plug into my PC,the LED turn red for 2-3 minutes then off, it doesnt even show QHSUSB. anyone know whats wrong?
hi! i have found similar threads, but they did not help me solve the problem, so here i am, writing a new one sorry guys. also sorry for my bad english, it is not my primary language..
i have an htc desire X which has a damage only on the outside display, the touch screen worked perfectly. then, all of the sudden the phone kept restarting, freezing for few seconds on the HTC welcome screen, then turning off again. it did that for about few hours then died completely, battery wouldn't charge either. on charge, red light on, no sign of life.
i have bought a new battery, and the phone turned on and did the same again, restarting every few seconds. i have pushed the low volume button + start combination, to have it go to the bootloader menu. since then it is frozen on that menu, stuck there. no buttons would work. they do work to get to the menu, but on bootloader not anymore.
i am a newbie, i dont know what to do, except for the fact that i have all contacts still in the internal storage and i was hoping to save them to an external disk/pc/microsd.
when i restarted the phone, the sim and the microsd were already out.
connecting the usb cable to the pc doesnt bring me anywhere either, my pc says "device not recognized" then it doesnt see any device.
please help me to get my data out somehow:crying:
little update:
this morning the "smart"-phone is not stuck anymore, i was able to get to the bootloader and select recovery, BUT unfortunately any attempt to push the on button to confirm it went wrong, phone keeps just restarting or freezes again on HTC welcome screen. any idea?
Hello.
I have the most weird problem.
I do not know if it's an hardware fault.
My phone starts and gets into a bootloop on battery insertion.
If I connect the USB cable, it restarts and turns on. Even Odin mode gets interrupted, so I cannot flash a ROM.
Also, the power button isn't working for some reason.
Could it be that the power button is malfunctioning and it's continually pressed?
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.

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
