Hi,
I use Uhappy UP920, chinese phone, 6 months old,
my power button is sometimes hard to press, it is not working so good, so, I used IDE terminal in my android kitkat to shutdown my phone. I used next commands:
su # to become root
shutdown -k
I saw it is switching off, but during shutdown, phone is not totally shutdown than there is still the name of the phone on the screen and it is frozen. I can press power button how much I want, no result, I tried to press it in the same time with volume button, no result. it is not possibly to remove batter and to put it back.
so, this is not about locked pattern, about working phone so I could install app for changing power button to volume button, this is about frozen android software, I can't start it, when I use USB cable, computer doesn't recognize the phone, so, battery is not charging. I don't have ac adapter, I use USB to charge it. but battery is not totally empty, battery was 34% full when I tried to shutdown the phone.
any help?
is there any software I can start from computer and push the phone to start?
in this moment I use windows 7 but I can try Linux too, as I said, when I put USB cable in PC and my phone, nothing happens, PC doesn't recognize the phone, phone is not recognizing USB cable, batter is not charging as it does usually when I plugin the cable.
hi, I don't see option to delete thread/topic, i solved problem with pressing power button very strng on the table, it was finally shutdown and system booted again. problem solved.
I tried to unlock the bootloader of my LG L Bello 2 phone, and after rebooting in recovery mode it would start. I tried holding down volume down and power button but nothing happened! So I plugged it in my computer, and it keeps getting connected and disconnected, even after I unplugged the battery and put it in again so it should've been turned off. It seems like the phone turns on without me pressing the power button.
1. I take out battery and put it back in
2. I connect it to the computer
3. Computer makes noises as it's getting connected and disconnected all the time, but it still never gets recognized by the computer. I tried LGs tools but it won't work as it isn't connected for long enough.
4. Volume down + power button trick doesn't work. Nothing happens. That's the first thing I tried.
(I hear no sounds, and it doesn't vibrate or anything, I only know it has some life because the computer made noises when I have it plugged in)
Any ideas? I've tried everything

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 ,

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.
