Random Shutdown

There has been a lot of talk about the random reboots since ICS, but i have a slightly different problem. Since updating to ICS i've had a few random shutdowns....i think, it might be that it freezes with the screen off, i'm not sure which. ive never seen it happen when i was using it, the battery is never dead, i just try to turn the screen on and it won't. I have to hold the power button down for it to do either a reboot or a boot from scratch not sure what it is.
here is what i have
- stock transformer (rooted in HC to fix left speaker volume)
- upgraded via ota to ICS (seemed to work correctly)
- not overclocked
- no other hacks
- haven't done factory reset (don't want to, but might if it keeps happening)
Has anyone else seen this since ICS ??

I haven't had that problem but I've had a lot of others from bootlooped, to the whole tablet freeze... I'm on stock ics and factory reset didn't help what so ever........

I started to read through that thread (lots of pages there), i didn't notice anyone with the random shutdown on there that's why i started this thread, just in case it started happening to other people too.
I will try some of the suggestions on there to see if it goes away.

Same issue here - it is either freezing while the screen is off or shutting down. Only way to get it to respond afterwards is to press and hold the power for 10+ seconds, release, and then again for 5+ to turn it back on.
I've reset to defaults with no success. Running stock rooted ICS.

Same issue!
I've noticed this happening on my tablet too.
Mines completely stock in every way, never rooted or modified in any way from stock.
After the ICS update I've noticed that... probably once a week or so I'll go to turn on my tablet only to find that it's essentially turned off.
There was plenty of battery, and no obvious rhyme or reason for the shut down ?!?!

Same here. Stock TF101, after ICS upgrade device doesn't respond to wake button. Plenty of battery. You have to hold the button for a way longer than just a power on press.

I've started having the same issue after updating to ICS. Sometimes it's random reboots and other times I'm getting this shutdown issue.

I have this problem too.
I try to fix this by changing the ROM but all still get this problem.
Stock ---> RevolutionHD ---> EOS with cornerstone 4

I have had same problem with the random reboot/boot loop problem with ICS and I have tried stock unrooted / stock rooted / Revolver / RevolutionHD. All do the same thing. If I have the screen off for extended periods of time, it reboots and gets caught in a boot loop. The 10+ then 5+ button hold works to get it restarted. I am trying different apps to see if one is the cause. Most of the time I seem to remember that I was browsing just before shutting the screen off.
Will let you know if I narrow this down as I have multiple browsers installed. Note: I mainly use Chrome and FireFox Beta the most, will try removing those and testing.

Same here, having random shutdowns and sometimes when I lock my screen it restarts and get stuck at the bootanimation.
Also it often reboots when I use Splashtop remote. It works well, then I touch the screen and it restarts...
I hope Asus will fix this as soon as possible, but i think it will take a while.

I believe this has to do with the power management issue. I've noticed that after being unplugged from the power supply. The tablet will stay on. Once when the power level dips below a certain percent, the tablet automatically shuts down. When it reboots, sometimes the wheel will stay stuck. The only way to keep the tablet powered on is to have the cable plugged in. That defeats the purpose of a portable tablet, might as well get a EP121 then.

[Q] Booted and crashed. Re-booted, crashed and dead

Received my Nexus 5 today after much waiting due to Google/courier making a mess of my delivery details over the last 9 days...another story altogether.
Straight out of the box, and after putting in my SIM, I stuck the phone on charge for a bit and booted her up, though it seemed like there was a bit of charge in it (40-50%) so felt happy unplugging it during some of the set-up...syncing accounts, connecting to wifi, sending a couple of test SMS and inputting my carriers voicemail number.
Then it crashed as I was reading a text, and wouldn't turn on again.
I put it down to teething problems and left it alone and on charge for a bit, and after 10 mins tried again and everything was fine. Booted up (and super fast at that). Spent another 20 mins or so messing around with wallpapers and adding a couple of apps that I use daily.
Stick it in my pocket to run a quick 10 minute errand (including trying to pair it with the Bluetooth in my car, unsuccessfully), and when I get back to the office I find the phone had shut down in my pocket, and it has now been unresponsive for the last 2+ hours.
I've tried leaving it on charge. Tried every combination of holding down buttons to elicit any kid of response, but absolutely nothing. Not so much as a screen flicker.
Would anyone have any advice on things I could try before I contact Google and pack it back off to them? I'm out of ideas. I can't get it to respond in any way to anything!

Try pressing and holding the Power and both Volume Buttons for about 15 seconds. Then try to boot.

Tried this (which I'd tried to no avail previously), and no joy. Wouldn't boot afterwards.
Left it on charge (which it had been for the 20mins previous to trying this) for another 10 mins. Came back to it, pressed power and it just came on. No boot. It was just already on.
Veeery confused now after trying intermittently to get it to boot for what is hours now.
Should I do a factory reset?
I'll log with Google that this has happened so there's less come-back if it dies again and I need to return it. Haven't tried it with a SIM in yet (need a working phone!), but will report back after that.

I'd fully charge it before doing anything else.

Have done now. It's charged and I'm about to retry the SIM.
Possibly of note, after I checked it and saw that it had restarted, I checked the battery log and it showed that it had been running for 29m 25s on battery...yet was on charge. I'd attach the screenshot but I haven't posted here enough times for the forum to let me
It was unresponsive no more than 10 mins previously. 10 minutes would be generous.
Anything I can learn from that?

So the phone lasted all night with some light use. Left my Nexus 4 on with no SIM for alarms so I knew I could wake up this morning, but instead, to my joy, I had two phones alarming at me together!
So it was to my dismay that after I'd read some mails, checked some sites, and left the phone to go and get ready for work for 10mins...I came back to it dead again.
I heard some notifications come through (and I was in the middle of a conversation on WhatsApp, so that was normal). I saw the notification light flashing too, so the messages coming through, or at least the first one, didn't crash it.
It did however start up again, with no SIM, after some cajoling.
Is there some way I can see an error log, or a crash log? Or anything I can install to log this for the next inevitable time? Or is this sounding like a permanent hardware issue and I'll need to return the unit?

There's a thread somewhere you can find it, it will show you how to install stock firmware again.
Do that and if it occurs again, call Google to get a RMA

Re-installing the firmware won't jeopardise my position in sending it back to Google, no?
Just went back to it to put the SIM back in it and it's unresponsive again. FFS.

No, but you have to unlock the bootloader first before you can flash a factory image and install adb (platform-tools) on your pc, and afterwards relock the bootloader again before sending it to Google.

Huge Irritating Problem with Note

Okay, so, I know I am not the only one with this issue. At the same time I know not ALOT of people have this issue. Lets get right down to it, I bought a Note I717 from someone who claimed that it was stuck in a bootloop. Well, I turned it one when I got home after doing a factory restore and it came on and stayed on. I thought I had fixed it until the battery died.
Symptoms:
Boots up fine
Stays on for around 2 minutes
Freeze then Reboot
Happens every time. I have tried to restore stock firmware, have tried custom roms. Have rooted it, unrooted it. Battery holds a charge and is perfectly fine. Power button is NOT stuck.
There have been 2 times I have got it to come on and stay on for like 12 hrs then it will freeze and cut off, then start the rebooting sequence all over again. Anybody think they can help me out?

whn i had a similar issue, the answer turned out to be that i was overclocking. if you are overclocking/undervolting it can cause random reboots.

My N5 randomly turns off after taking a picture

Hiya,
I've got this issue for about two or three days now. Quite often, when I take a picture with stock Google camera app, my Nexus turns off instantly. Then, when I try to turn it on again, it often turns off again in about one minute and usually it shows almost empty battery (even though before shutdown it was nearly full).
First it has appeared on stock rooted 4.4.4, the phone tried to boot like 10 times, so I erased cache and dalvik via TWRP, but then it didn't detect SIM card and showed unknown baseband. I solved it by flashing bootloader and radio.
Then, I installed a stock 5.1.1, rooted it again (I thought it would solve the issue), but the same problem with camera occurred.
So, could it be hardware issue? How to debug it?
Thanks for any response.

Hi,
Probably not an answer you'll like, but I've experienced similar symptoms on my HTC Sensation with HTC "stock" android on it (phone turning off and then having much less - and sometimes MORE - battery-time left after booting again). I never had an answer as to how to troubleshoot it, nor did I get help (from HTC) to solve the issue until at some point I found that the battery itself wasn't seated properly, and after putting some paper between battery and case to put more pressure on it (which doesn't seem possible with the N5) the issue magically disappeared...

Very recent N5 topic: http://forum.xda-developers.com/google-nexus-5/help/nexus-5-random-shut-off-battery-drops-t3162481
A tip in that topic: "it doesn't happen when connected to power cord". Possibly you can try that to add it to the elimination-process?
Hope you can get it sorted!

Stuck in a bootloop, but I didn't do anything to my phone

Hello, Nexus 5 forums. This is my first post on here, because I never even tried to root or install a custom ROM on my Nexus 5, having bought it for the official updates from Google and all that stuff (I had a Galaxy SII before this phone, and I frequently visited the XdaDev GSII forums because I installed CyanoGenMod on it).
I'll go straight to the point. My phone suddenly started rebooting randomly today, and by the end of the day it was stuck in a weird kind of bootloop. The Google logo would pop up, and right as the MM boot animation started the phone would reboot and the Google logo would show up. Right now, the phone's battery is probably dry, so that's why the phone isn't bootlooping, but it has done so for 3-4 hours before shutting down. I tried opening the phone, removing the battery and putting it back in, but the phone just kept bootlooping. I tried both getting into the stock recovery and into download mode, but the phone keeps on rebooting as soon as I get into download mode.
Can I do anything to fix this or is my phone doomed to the eternal bootloop?
Thanks in advance for any and all replies.

Sounds like there may be a problem with the power button.

Same thing happened to me like 5 times now. It is the power button. What I do is knock it on the side of a table below the power button. I just need it to last until the new nexus is released, so I never investigated the proper fix.

I understand, so my problem is more a hardware than a software issue. I tried knocking the phone on the side of a table like @NicksSpleen said, but maybe my problem is more serious. What can I do to fix this? I need it to last until Christmas, as I'm going to get a new phone then (maybe the Nexus Sailfish, if the price is acceptable).

EDIT: Double post.

I disassembled my phone and fixed the problem by cleaning the power button. Works like a charm. Thanks for all your suggestions!

Anything other than the power button?
