Hi,
After disabling some app and disabling background data for some else apps, I turn my phone off.
Now, it could not charge and do not respond with the power button.
Z5C on Android 7.1.1 root with TWRP.
Plugged in usb, on the power adapter : nothing on screen. And on USB, the same.
I saw this list of apps :
https://sky11362.pixnet.net/blog/post/35365493
I'm sure I have disabled this one : SemcAutoPowerOff.apk
For others, I don't remind me... I've got a TWRP backup of my phone (outdated but maybe useful, 2017).
Is it possible to restore the apps states and privileges with TWRP or something else ?
I'll retry later, when battery will be really empty. Hope it can rebirth !
try to hold power button + volume up button to force shutdown.
Maybe it just hang during the shutdown phase
So... After waiting all this afternoon, I push the power button during maybe 30 seconds.
It came back ! Battery was below 25%. Everything is ok. :silly:
I'll recheck my disabled apps...

So I used my nook tablet all day yesterday and this morning. I put it down to goto lunch.. came back and noticed my wifi was not on.. I checked settings and it showed "Wifi turning off" and it was grayed out and just stuck.
I've seen this before with other android devices so no biggie. I powered the unit off.
Now it won't turn back on. Holding the power button now for about 20 secs and nothing.
The battery is at like 80% and I even plugged it in to see if it helped but no good.
I did root it at 1.4.0 and used the Block OTA method with titanium backup but nobody else seems to have a problem.
Is there a way to boot in recovery or something ? Perhaps a trip back to B&N will be needed.
Ok.. holding vol down + power for around 8 secs got it back on. Weird
i have noticed this a few times. Not sure why but never lost anything

His happened to me once and I don't know what I did to get it back on. Glad that I now know, thanks.

I had a similar problem. I couldn't get the tablet to turn on. I discovered in a Kindle Fire forum that you could get the Fire to start when stuck in the off position by holding down the power button for 20 seconds. I tried that with my Nook and it started right up.
Thank! That worked! I was having the same issue. Said Wifi was turning off and all went blank and couldn't reboot. You gave me the answer.
Cheers.
I have had the wifi "turning off" issue. Rather than turn off the nook, I used the menu that you get with a long press of the power button when you install either ROM manager or titanium backup, can't remember which. It has rebooted every time without issue.
The Wifi issue is a known problem. You can set the wifi to stay awake when on the charger and this problem wont happen. Add the power widget so that you can turn the wifi off when not connectwd to the charger. This combo fixes the wifi issue. When your Nook experiences a kernel error it will appear as if it is off but if you hold it at angle, you will notice backlight is on. Just hold nook button and power and it will turn off...then power to reboot rom.

Actually, it's happened to me twice while I had WiFi set to never sleep when charging.

I rooted my Nook Tablet and it worked fine yesterday. Now it won't turn on and isn't recognized by my PC. I hear the windows alert when a usb device is connected but when I try to do anything via adb I always get 'error: device not found'.
I tried doing adb get-state and all I got was 'unknown'
I tried booting into recovery via holding the power button + n for various amounts of time, but nothing happened.
Does anyone have any ideas? It was working fine yesterday and I haven't changed anything on it since I used it last.
Hold the power button down for about 10 seconds. let it sit for a minute, then hold the power button for another 5 seconds or so and release. It should boot up. (assuming your battery is charged)

I had to do a reset (power button + Home) twice so far. Each time it happened after I left the tablet to recharge overnight. It did not turn on as it normally does when you unplug the charger.
I must admit that the (power button + Home) reset does not seem to be cut & dry. The routine quoted above worked the first time. The second time, I tried it several times then finally I tried the pwr button by itself and it went on.
Mine just did this Power and vol down got it running again.
Hello guys, I'll try to be as brieff as possible:
My cousin has a SGS3, which suddenly started showing the power options screen (when you long press power button). Now his phone restarts on its own every time. When you insert the battery, it turns on by itself. If you try to access download mode or recovery mode, it does it but restarts again. I read it may be the power button is not working properly, but I dissassembled the phone and the switch is works normally (it's not broken, either stuck). I read several solutions about clearing cache and stuff, but it just keeps restarting! Like if someone were pushing the powerbutton every time. Btw, he discovered he can turn the phone on and actually stop the phone from restarting if he continously presses the power button and menu button alternatively without stopping (which is useless). When he stops doing that, 3 secs later, it restarts again. Any suggestions?
It's a hardware fault, did you test the button with a meter?
If yes then something else is shorted, to power on when the battery is inserted.

Ah, so this is merely hardware. I did not test it, but now it seems clear something is wrong on the inside (which, unfortunately, I cannot help with). Thanks mate!
I have several issues with my gt-p7510, ics 4.04.
The first is, there are some files i just can't delete. Not system files, some created by me and others downloaded. I've tried some file managers without success; there's no error msg, they just remain there.
The second is i have difficulties to turn on the device: i have to press the power button + volume down for like 30 seconds whenever i want to turn it on; besides, the device wont charge battery if i turn it off first. To make it charge i must connect it while is on and after that turn it off, that's the only way to get the battery charging animation while is off.
Is similar to the classic "my tab wont turn on" and "dont charge" but, i have to do the trick every time i turn it off. An i dont have battery issues, isnt rooted, has official firmware and battery has never been replaced.
Like i wrote, i must hold down power + volume down for like 30 seconds every time i have to turn on the device.
Any help?
So I had the OTA update for 5.1.1 the other day and thought "yay, let's update." it worked fine till this evening where it crashed to a power off state and in now showing the Google logo like it's about to load up and then a turned off screen.
This repeats over and over I can't even stop this loop.
Holding the power button and it just continues to loop.
Power + ANY volume button and it will show the HBOOT or fastboot menu then before I can select anything turn to the powered off state and loop through (if I'm still holding the buttons the menu will show again shortly, or go back to the Google logo)
Any ideas for a solution?
try waiting until the battery drains all the way down then hold the volume down button and plug it in. if that doesn't work then all you can do is contact google support and they'll probably replace or fix it.
Hold the power button down for 20 seconds 3 times. It helped me once with a similar situation
So I have found a solution. Instead of deleting the thread I'll leave this here unless anyone else has this problem.
It seems that trying to enter the fastboot menu when plugged into a USB seemed to work.
It was either the fact it was in the computer, the timing I pressed the "power button + power down" combo, or it had just looped enough times and decided to actually stop interrupting me using the fastboot menu.
Either way, I cleared the cache partition using the recovery and it booted up fine.
EDIT: Thanks for the help, I had tried holding the combo for a long period of time (multiple loops of the booting). I also feared letting it drain in case it refused to startup again and I would have no chance of fixing it.
glad you figured that out! android can be mysterious sometimes. especially when it's on the nexus 9.
I have a rooted c8633 and factory reset it yesterday, then battery suddenly dropped from 30% to 0%.
1. After turning it on again, the power button wont work(cant screen on/ off) . But i can still use it to power on or force turn off the phone (power + volume up), so i assume its some software problems but i didnt install any apps i never use before.
2. The battery percentage seems not accurate, sometimes it drops fast but some times its very slow.
Could anyone please help with these problems? Thank you.
Sorry i cant capture any screen because my power button is not working.
