[Q] My phone won't turn *off* - G2 and Desire Z Q&A, Help & Troubleshooting

Hi everyone,
It's been a while since I've been active here, but I've recently discovered a weird problem with my phone - I can't get it to turn *off*.
I rarely try to turn it off, so I have no idea how long it's been doing this, but I was on a plane recently and discovered that whenever I try to power it off, it'll pop right back on as soon as it shuts down.
I'm on CM7.1.0, but it's the same when I go back to my nandroid backups of 7.0.3, 7.0.2, and even stock 2.2! I have then eng-hboot (0.76.2000), radio is 26.08.04.16_M, recovery is CWM 5.0.2.0, but the same thing happened on 3.0.2.4. I can provide more info if needed.
Can anyone help?

Just... take the battery out?

But I mean how long is he going to keep his phone off for? If you're keeping the phone off for a long time, you shouldn't store it with the battery inside anyways.

Does this only happen when the device is plugged into the charger/connected via USB?

1) Yes, pulling the battery works of course, but there should be a way to turn it off without doing that. And it comes on instantly when the battery is reinserted.
2) It happens regardless of whether it's plugged in or not.
Maybe I should try re-installing the engineering fastboot? Or try a different radio?

This was happening to a lot of CM Nightly users a few months ago (myself included), and it fixed itself a few days after it started. I still have no idea what caused it.

This happened to me just the other night. I needed to power off for a short while - I pulled the battery. I don't think it happens every time, but I was able to pull the battery and then reinsert it without the phone rebooting immediately.

It happens to me form times to times but i think its nothing serious so i just take the battery out

An update - I tried turning it off while plugged into my computer and watching the log in DDMS; it *CAN* turn off when it's plugged in! Still nothing when it's unplugged, though.
Anyone have any ideas how to fix this? Like others have said, it's not like this is a major problem - I can always just pull the battery if I need the power to be off for some reason. And it's not like phones really need to be off for air travel, so I can't even think of a reason I would need it off, but still - this is obviously a flaw in something, and I can't stand knowing that it's not working exactly right. I think I'm going to flash a different radio, see if it makes a difference, but if anyone has any ideas how/why this is happening, I'd really appreciate you sharing them.
ETA: updating the radio didn't change anything.

same problem--- keeps turning back on
IOn my Desire Z running MIUI, i turn it off and it shuts down to turn itself back on! Very annoying, particulary when on a plane. Taking the battery off, OBVIOULSY fixes it. But not a very practical solution.
Similar to post above, it stays off when connected to USB. Go figure!

I think I read somewhere that this was a clwm issue with the most recent recovery, have you tried flashing a different one? Older or maybe try 4ext?
PS just reread your first post sorry, it seems you already tried a different recovery.

For the OP, since you tried reflashing, and I'm sure you wiped, then I would imagine it isn't a issue with the ROM, the radio didn't help so maybe bootloader or recovery.

OP here, sorry I hadn't checked in for a while. For unknown reasons, the problem's gone. No big changes to my phone, so the issue vanished as mysteriously as it appeared.

[Q] Q: Anyone elses HOX powers up on its own while turned off and charging?

Since the first ROM I have a strange problem, everytime I turn my One X off, plugin the charger it keeps not only charging but will power up the device to normal mode eventually - i.e. no special charging mode etc. It sometimes takes several hours but in the end it will always be on which is really frustrating.
I've tried different ROMs with different Kernels, I'm now on CM10 nightly - still it powers up magically if I have turned if off before and plug in the charger.
Does anyone else have this problem??? Any suggestions?
Same here
I've got the same issue. Exactly as you described.
I don't have any idea why is it happening - is it a hardware or software issue.
:silly:
It's part of CWM. Flash stock recovery if you don't want this to happen then you'll lose root.

What is your cwm version? Try upgrading to 5.8.4.0.
Is this on One X only because I never had that on any other device?

Mine is 5.8.4.0.
Can you try reflaehing it? Earlier versions had that problem.
Also, you can try it with twrp to see if that helps.
EDIT. I may have misunderstood guys. Earlier cwms wouldnt let you stay powered down after shutting the phone down. It would turn on even without plugging in.
EDIT2 Turned mine off. Plugged it in. Remains off so far. Will see in the morning. It certainly sounds like cwm problem. Try twrp and see if that helps.
I do already have 5.8.4.0 :-\

You are not alone, all of us are facing this one, and i think it's pretty normal.
If you drain your battery to zero, and if you start to charge it, one hour after (that's what i've noticed) it'll boot up and it'll show up your lock screen.
This is normal for the HOX?
Im completely stock, un-rooted etc etc.
And when my HOX is off, when I plug the charger in it boots the phone. But then if you switch it off whilst the charger is on, it will not re-boot up.
It still happens, I have reflashed recovery and stuff and it still turns on itself.
I just tried it over night, started with a 41% charge left, turned it off, plugged in the charger and this morning it was turned on. :'(

[Q] Rooted phone and now wont turn on

I recently Rooted my sealed samsung galaxy s3 without having a clue what i'm doing i downloaded this program called snapdragon to root it along with ODIN. The phone rooted fine everything was working okay, I even downloaded an app to see if the root was successful and indeed it was. I shut the phone down wake up in the morning to turn it back on and I get zero response. Any help/direction would be greatly appreciated.
Thanks!
Might seem obvious, but have you tried leaving it plugged in for ten-fifteen minutes?

Yes of course I've tried leaving it plugged in for several hours and the night before the phone was at 100% charge so I doubt battery is the issue.
Tks though
Did you try booting into recovery?

Ummm seems like u can fix it.... go bak to stock using odin as well and go back to stock and i believe cwm is going to be gone so as your root access so re-do it but this time guide yourself through a turorial(a.k.a google) and since you have to clue i think the best choice for you is to find a video tutorial in case your doubting or getting confused with the steps or sometimes to see what you did wrong that caused the phone to misbehave...

This is why I hate one-click-root kits, you get people doing things to their phones they don't understand, wreck it and come here saying "help, I don't know what do do!" Something like this you really should at least understand the basics. I hope this gets you more involved in researching what's actually happening. It's important to know what's happening to your device as well as why, that way if something goes badly you'll have an idea of how to get out of it.
Sorry, enough lecturing, let's see if we can get something going here. Give a bit more detail about what happens. You're phone is shut down, right? You hit the power button and no response, like the battery is actually out of the phone, or does it turn on and give you a blank screen? If it was a brick, I'd think you'd at least see the boot screen before everything goes wrong.
Ok, I'm going to go ahead and assume you've removed the battery. If you haven't, do so now.
If it still won't turn on, try actually holding the power button down for 30-60 seconds. I had a scary moment with my phone yesterday, rebooted it running Wicked v5 on Trinity and the screen just died. I've been running that rom for a week with just a couple of issues here and there, nothing out of the ordinary. Pulled the battery and tried again, nothing. After holding the power button down for a bit I felt a quick vibrate, then the boot logo came up. No idea why, I'm going to have to look into it.
Beyond that, I'm brand new to this phone and Sammy's Android devices so I'm still learning myself. HTC phones I could help out more with, but I'm still a bit clueless with this thing.

Yes I have taken out the battery replaced it several times. I hit the volume home and power button several times. When I do that I get a zero response nothing shows up I hear no sound its as if the phone is just completely dead. One thing I did realise is when I plug it into the computer and press the power button what would happen is it would connect and automatically disconnect
Can you get into Download mode? Volume down + Home + Power button?
Sent from my SGH-T999
Don't forget to let go of the power button when going into recovery.
Have you done what the other post said?
Hold power for about 10-30 seconds. Does it do anything? Do you feel a verrrry slight vibration?
When you plug it in without doing anything else does the computer see it in device manager? How about if you press power once? Or holding power down?
Does it register that its charging?
This may sound dumb but did you try powering up without the phone plugged into anything?

Ummm. Sorry but maybe im missing something? Your first sentence in your op says you didnt have a clue what you were doing....
And where is it supposed to infer that you've done everything already?
Imo you have been getting 'real' advice but from what I see you haven't 'really' answered anyones suggestions.
No one can help you if you dont tell us what exactly you have tried and what what happened when you did.
For example in your only response you mentioned hitting the volume and home keys a bunch of times....what exactly do you mean by this? Did you hold them while trying to power up? Volume up or down? Did you release any of them during that process, and if so which and when?
Its kinda hard to help someone who doesn't have a clue what they are doing and only responds that hes done everything common sense dictates.
I seriously mean no offence but to me common sense would dictate that you not try rooting or anything if you know you dont know what you're doing.
It would also dictate that if you want further help with this you should go back and respond to what everyone suggested.
Like I said, im not trying to offend, just help.

I am having the same issue
I just tried flashing Android Revolution to my phone. I went through the whole set up process. Went to reboot then it went blank. Nothing. I get nothing when I plug it in. The computer doesn't recognize any device attached to it. I've tried all the ideas listed here and I get nothing. It's as if the phone is completely dead. When I flashed the rom my battery was at 90%. I've used various roms on different phones and this was the first time I did it to my Galaxy s3 and this is the first time it's ever happened. Talk about frustrating.

[Q] KF2 battery problem after CM10 install

Hi, new here but I've been lurking for a while.
I followed Powerpoint's guide to instal CM10 on my KF2
http://forum.xda-developers.com/showthread.php?t=2105077
Everything was running great and has been since I first loaded version 3 a few weeks ago, and last week i went to version 4 of powerpoint's rom with no problems. Then a couple days ago after i had been browsing the internet on it for maybe 30 minutes, I set it down and when i came back the screen was off and wouldn't turn back on. so i figured the battery was just dead, so i plugged it in to the wall charger. At first the charge/power light wouldn't come on at all. Then after several plugs and unplugs the orange light started to come on but would only stay illuminated for 30 seconds-ish. So I tried it on my phone charger and the orange light came on and stayed on, so i decided to let it charge overnight. The next morning the light was still glowing orange so I unplugged it and tried turning it on, but still nothing happens. But when I plugged it back in afterwards the light came on green. now it has been plugged in for almost a day with the green light on but it still wont turn on.
Anyone else have this problem? Any ideas what i can try? for obvious reasons i can't exactly ship it back to amazon lol
p.s. I have a final on friday and the text book for that class is on the kindle. So urgent responses will be greatly appreciated.

It just happened to me again, seems to be a recurring problem. Anyone have a clue what's causing this?
on a side note, perhaps this problem could be dealt with simply by installing a battery management app like juicedeffender. any thoughts?

Wow, for once I can completely and knowledgeably help with almost no guess work!
The issue is Sleep of Death.
The cause is unknown, and due to the nature of how to reset it, it's been difficult to get logs. It happened to FMK not too long ago and last I heard he was going to get the logs (to find what causes this) and get those to Hashcode to look at potential fixes.
It's not battery related....well in the sense that, if it happened, you reset the device, and looked at the battery, it should be at a similar level to what it was before.
TO FIX
You guys were right on fixing it mostly.
If you ever press power a few times and it won't turn it, don't bother fretting about it. Just do the hard reset, which is holding the button down for 10 seconds. After you do that the device will reset to the point where if you just press the power button once, it will boot up like normal.
I would hold it down for about 15 seconds just in case, or if you have headphones it, you can here when it does the reset and can get used to the timing.
I would say....in a few weeks with the device, I've had the issue around 5-6 times.
I've also NEVER had it happen while I'm doing things, so it hasn't caused issues besides making me a wait a bit before using the device, which is good. If it happened during doing things I would want this fixed ASAP, but so far, no major issues.
agreed, if it was happening while i was trying to do stuff it would be problem. As it is though, I just consider it a minor inconvenience. Glad to know I'm not the only one experiencing this though.

I wouldn't call it a fix. I would call that a workaround. We need a fix, and I think if anyone could get an effing log to hashcode of it happening, we could fix the problem. I think it is a kernel problem, what with the recent merges and such. I think something is incorrectly copying from kf1 to kf2... if anyone understands what I'm trying to say, it makes sense..

I wonder if pulling the log cat via adb would work, I.e. wait till it goes wrong' then connect it to a PC to pull the log. The issue is its very random and being at a PC to do it when it goes wrong could be tricky.

the hard reset (power button for 20s) clears memory

[Q] Anyone experiencing powering off and troubles switching it back on (charged)?

Hello guys,
I tried to search for a similar issues but I couldn't find anything similar so please bear with me.
My KF sometimes shuts down overnight. In the morning then I have troubles to switching it on again (clicking the power button, holding it for longer periods of time...). It usually helps for the tablet being connected to the charger, but it takes a few tries to turn it on. After I managed to turn it on again, for example yesterday, it had 80% of battery left.
I am using CM nighties and this is happening already for some time.
I am also using juice defender, I am not sure if that is relevant.
Do you have any suggestion, what could be the cause of this? Maybe a suggested alternative rom? Or some logs I can check? I think the powering on troubles bother me more than the shutting off overnight since I always think it won't come back on anymore.
Also, not sure if relevant. If I try to turn it on and it doesn't, sometimes the button flashes orange. After a few tries it turns green and powers on. Not sure if I am now not only confusing times, when it was simply out of juice.
P.S. On a different note, just curious, does anyone know how if there is a rom with working mic already?
Thanks in advance.

Yes, I sometimes have the same issue with the power button - in fact it happened to me this morning where I went from about 60% charge to 16% with a sudden power drop.
Not sure why this happens. I thought it was a bad battery so I changed it but am still getting the problem every now and then.

the only thing that i can think of is that during the middle of the night a soft-reboot happens and it cant boot back up into the system. this would cause it to sit there and continually try to boot up. this would use a lot of cpu and a lot of power. as for why that drains battery while being plugged in, well i cant help you on that.
Thanks for the input. I've wiped dalvik, cache and the system and installed hashcodes AOSP Jelly Bean (http://forum.xda-developers.com/showthread.php?t=2041694) and at least it survived this night without shutting down so maybe this helped. If I come across the same issue, I will update this thread with new info.
Thanks again,

Sounds like a hardware issue, and Amazon has been replacing those of customers who buy new from them.
Mine has this issue too. I KNOW it has battery power, and is still on, but the screen won't turn on. Only solution is to plug in power, then hold down the power button until it shuts down hard. Then turn back on.
I'm returning mine because of it.
Thanks for the info. I am still hoping this is a software issue.Regrettably I am outside o the US and thus replacing it is nearly impossible. I will see, if the issue returns with the new rom and will update the thread if it happens again, just for your information.

Try going to the WiFi settings and selecting 'never' for keeping WiFi on during sleep. This seemed to work for me.... So far it hasn't happened again.

I think this is the bug I am experiencing:
Shutdown bug stalls out the shutdown. Looks like the device is off, but it's still powered draining battery. Currently requires long power button press to fully shutdown after the screen is black (about 15-20 seconds).
from the 3.4 kernel thread (http://forum.xda-developers.com/showthread.php?t=2264563). I am not sure if cm 10.1 nighties contain this kernel, but the description is pretty much spot on.I couldn't test the fix (holding the button for 15-20 seconds), since I already changed roms, but if someone experiences the issue again, he can post if this works and which rom and kernel they are using.
This happens to my Kindle Fire device as well. It just randomly shuts off and it won't come back on until I do a hard shutdown then turn it back on. I currently have AOSP Jelly Bean 4.2.2_r1 on it.

Yes, it happened again to me with the same ROM, but it happens less often. I will try the updated kernel once it is finished.
On May 27, 2013, Hashcode listed the known issues of the current kernel on his website:
Sound / MIC debugging
Deep sleep issues with “omapdss_dpi” device
SmartReflex shutdown loop fix.
Charging driver / OTG improvrments

Looks like they've been identified and are being resolved. :good:

Random and untimely reboots

Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case
It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?
OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
