Nexus 7 (2013) Power button and booting problem - Nexus 7 (2013) Q&A

Long story short, 1 month ago my Nexus 7 (2013) got water damaged, I immediately covered it in rice and left it for a couple of days, and after turning it back on, have a weird issue.
The power button will not work what so ever, I've tried holding it in for over 60 seconds, aswell as holding in the volume buttons along with the power button.
The only way to turn it on is to plug the nexus into the mains. I then get the white LED flashing 5 times, which I assume means it's charging up from a completely dead battery.
After about 20 minutes of charging, the google logo will pop up, stay on for 3-5 seconds, then the unit will reset itself (screen goes off, then back on to the google logo, and repeats like that).
However....If i hold in the volume down button, it'll boot up like normal, everything works fine, but take your finger off the volume button and it'll reset and only boot to the google logo. Holding volume up will take it too the boot loader.
The issue is that at no point, (in the bootloader or once its booted in to the OS) will the power button work whatsoever.
I first assumed that the button was broken, and stuck to the ON position, so ordered a new button cable (which includes the power button, volume up and down, aswell as the microphone) but this hasn't done anything.
Wondering if anyone had any thoughts?

[Q] One X crashed when charging and won't boot past htc screen or power down.

I went to plug in my one x to charge. The second that I plugged it in, the screen went black. The home and back keys were still lit up. I'm not sure if it auto restarted or I powered it down. After that it seemed like it was just going to restart, but it only got to the htc logo screen. The normal little orange bar showed loading. I think it only does that once normally, now it goes twice. When it finishes that animation, it just sits at the white htc screen.
I haven't modified anything recently. It has been running over a year with no changes. If I hold power down at the screen, the home keys flash every few seconds. After seven flashes, the phone powers down and immediately restarts. There is no way to power it down until it dies. I took it apart and removed the battery for a few minutes, that didn't help at all.
If I home power and volume down, the red charge light comes on a few seconds. It then seems to boot to a black screen. I can't see anything, but the home keys are lit up. If I hold power down a while, it goes back to booting to the white logo screen. I tried hooking it to my computer, but it isn't getting to a point where it is being recognized as being plugged in.
I assume the thing is beyond help, but any suggestions would be greatly appreciated.

"home power and volume down"?
If you mean HOLD power and volume down, trying to get to bootloader, and you cannot, you're not going to be able to do anything else with and to your phone I am afraid.
If you ARE holding down the Home key in the process, I am not sure if it makes a difference but don't.
thanks

Sorry, you are correct, it should have said hold. I tried to edit it, but it wouldn't let me edit so soon after posting as a new member. My phone has been through a lot. In the process of opening the case many times, the volume bar got damaged. I have to use something metal against volume down to manually trigger it. I'm fairly certain that it has tried to boot into the loader though. I guess the charger had a short and fried some memory..

[Q] power button automatically pressed

So I have my htc one x for a year now. Rooted and custom rom, all worked fine.
The keypresses of the power button will be simulated very fast with no actual pressure on the power button. So after some minutes off locking and waking my device I pressed volume down and power button. Now sometimes it simulates the volume down and power button.
So sometimes it shuts off the device.
So I opened the device and there appears to be nothing wrong with it. I turned my HOX on and quickly unplug the ribbon cable from the power button off. But the power button is still pressed really fast, like 2 times a second.
I can't even go into recovery to backup, restore or flash anything because it will press the power button really quick and after 10 seconds it turns itself off.
It happened before on Slimbean rom. But the problem went away after some days. Now i got MIUI and the problem is back. So I don't think it is rom related.
My solution:
Is there a way to disable hardware keys in the recovery? Then i can try to restore my official RUU nand..?

Tablet not powering on? Brick?

The device responds to any button presses with the image that says 0% battery. When plugged in long enough it stays on "Needs more power to turn on." It has power, it can continuously respond to button presses with that bright image for hours on end. Attempting to boot into recovery/download mode responds with the same screen no matter how long I press it. Holding the power button for any period of time while unplugged results in it showing the battery 0% and then going to blank screen a few times then staying on a blank screen while immediately responding to any other button presses with 0% battery. Holding it while plugged in results in an infinite flashing 0% battery logo that flashes on for a split second every few seconds. Help?
Something similar has happened to me.
I installed TWRP and CM11 on it a few weeks ago. It had been running fine. A couple days ago I accidentally let the battery run completely out. Now it won't charge or power on.
It doesn't appear to be charging at all, doesn't get warm like it normally would when charging. Pressing the power button does nothing now, first time I tried to power it on I saw the plug image indicating no charge, but now I get nothing at all.
I've tried holding the power button for 30 seconds (and longer). I've tried holding the power and volume down buttons together. I've left it plugged in all night. It seems to be completely dead now.

Weird problem with screen/power button

Background -
I bought this OnePlus 5T with a smashed screen to fix.
Paid 70 bucks for it plus the screen is just shy of 150 in total.
I was able to replace the screen and frame which was a little more complicated than I anticipated, but it ended well and the phone seems fine, although the screen quality isn't as good as stock.
***Problem - it seems that for unknown reasons, after turning off the screen pressing using the power button, screen becomes black and won't turn on, not until i hold the power button for ten seconds and restart the phone the hard way. Then the phone turns on and starts working again, but if I turn the phone off with the power button then it won't turn on again. I can tell the phone is working behind the black screen, vibration working, notification light working. But Everytime I turn the phone off with the power button I have to hard reboot the phone to get it back on again. Once this starts happening I have to factory reset to get the power button functioning normally again. It will work normally for a day or two and then out of no where the issue comes back again after pressing the power button - screen won't turn on.
Could it be software? I know it might be natural to suspect the screen is faulty, but the screen works normally until I use the power button to turn it off, and then works normally again for a couple of days after a factory reset ...
Thoughts ?

Question Black screen but still working. How to shutdown phone

Hi,
My Pixel 6 Pro screen went black, but I can still hear and feel that the phone is working. I used the volume up + power button to reboot it and now I touch the phone and I feel it vibrate as it's registering the touches. I also see at the bottom of the screen some white stripes flashing. It seems that the screen is damaged and I need a replacement screen.
Now my issue is that I can't seem to turn it off. As the screen is black, the only way to shut it down would be with hardware keys. But up until now, I haven't been able to figure out a way to turn the phone off.
Does anyone know how I can turn of the phone?
To replace the screen, obviously I need to turn it off first...
Usually long pressing the power button, but it may be different. As long as it gets fixed within a month or so it you can let it discharge until it auto shuts down. If more than a year old replacing the battery when repaired is a good idea anyway...
I tried long pressing the power button with no luck.
I tried volume down + power button for 20 seconds, didn't work either.
I tried volume up + power button for 20 seconds, this I think reboots the phone.

Power button only might take 20 or so seconds.
Otherwise just like it sit until repaired.
Power button + vol up + vol down. Keep holding down once you feel the phone vibrate. Takes you to the bootloader screen
The battery died.. so that's good!
Thanks anyways
