My phone's power button is busted and my phone is off. Is there a way to get adb authorization?
Note that my phone's USB debugging is already on. I have also allowed USB debugging once but I didn't check the box to always allow.
I know this post is almost 3 years old lol, but i want to try to help, Hopefully you still have the phone!
To power the phone on, try to take apart the phone and use a wire to connect power from the battery or USB to the power button output terminal (i am not sure if this can cause any damage!)

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.
Hi, I'm not sure how to start this, sorry..
My LG G5 has a problem where every time I plug in a OTG cable, a notification comes up that says power supply.. When I tap on the notification it give the options like charging only, power supply, MTP etc..
If I tap on MTP, the notification will go away, then will pop up again POWER SUPPLY. It is very annoying.
Not sure how to fix it. Any help is appreciated! Thank you!
Maybe the otg is lose thaty why its fluctuating try again by placing the phone on any surface like bed or table plug the cable and try not to move the phone and cable, this is what i do when i connect my phone to my computer if the phone is in my hands then i face the same problem so i follow this method i mentioned
Hey.
Short description: My Oneplus 3's LCD was destroyed to atoms. I'm trying to use Vysor to control the phone through my computer. I actually have USB debugging already enabled from developer options, but that is not enough, as the computer's MAC address needs to be "allowed" for debugging through a prompt that appears on my phone's notifications. Any idea how to do this?
A bit longer description of how I know that the MAC needs to be allowed through a prompt: The LCD broke during two days. First I saw partially what's on the screen, so I was able to enable USB debugging and install Vysor. It worked for these two days, but once a day I needed to allow my computer's MAC for USB debugging through the notifications of my Oneplus 3. Now I cannot do it anymore, as the screen has gone pitch black. Also, ADB says that the phone is offline / it cannot be debugged at the moment. I wish I knew the exact location of the prompt so I could just allow it, since the touch screen still works... There must be another way.
If the touchscreen still works you could just try to hit the button blindly, it's not like missing would be an issue, right?
I tried hitting the prompt blindly, but it's either not there or I already opened it and pressed "decline" which made it go away. :/
Has anyone ever tried to set-up the Tab S6 to auto power on when connected to USB charger, without rooting device?
I'm thinking of adding this to my car. I can have the device power down with MacroDroid, but still need to figure how to turn it on when I don't have access to the Power Button.
I did find a video that someone was able to do this back in 2016

But when I boot into recover mode, it can't get the fastboot reboot to detect my Samsung S10+. So I'm afraid it might happen with this too.
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.
