The only time it would ever reboot when it was stock was when opening the camera app. Happened before and after 4.0.2. It would lock up and reboot about 25% of the time when launching from the homescreen and about 33% of the time launching from the lockscreen. Now that I'm running GummyNex it never locks up with the camera app, but occasionally locks up if I hit the settings button on the notification pulldown before it's all the way open. I assume that has to do with Gummy's notification toggles, but don't know for sure. I know if I wait for it to open completely, I never have reboots anymore.

I haven't had a reboot in over a week. I haven't installed or uninstalled any apps so nothing has changed. :sly:

Galaxy Nexus in reboot loop

My Galaxy Nexus phone from WIND went into a reboot loop yesterday. It had been charged to 98%, used to make a call and then put away. Wireless was enabled. Noticed vibration periodically and say it was rebooting every 6 - 7 seconds. Pulled battery to stop reboot. Saw references to fully charged battery via USB stops reboot loop so tried that. Battery voltage was 4.17V and still went into reboot loop.

Tried to boot into safe mode but still goes into a loop

I went into recovery mode and tried all options but factory reset because I am hoping to recover some pictures

reboot system now

apply update from cache (but did not have an update to install as only options were ../ lost+found/ recovery and when I selected these was in a loop as well)

wipe cache partition

Can't tell what version of Andorid I have as the phone never finishes booting.

Boot console gives the following information

Product Name – tuna

Variant – maguro

HW version – 9

Bootloader version – PRIMEKK14

Baseband version – I9250UGKL1

Have installed SMS backup because I was planning to do a backup after a trip. Also have two GPS tracker apps installed.

Update #1

I saw references on the web to a new battery helping or the extended life battery solving the problem. Last night I went to a mobile shop and they let me use a new battery to see if the loop would start. It did not help and still went into the reboot loop. This is the original ROM, I have not unlocked the bootloader.
[Samsung Galaxy Nexus] cmstlist:
Had you ever unlocked your bootloader to flash ROMs, or were you running completely stock unrooted? My phone did exactly the same thing (constant reboot without ever getting past the Google logo) but I believe it was because of a bad custom ROM.
[Samsung Galaxy Nexus] Ryancoke:
If you can solve this problem WITHOUT having to hard reset the phone I would be indebted to you. Mine just did this last night for the 3rd time and I refuse to do a factory reset. i have way to much valuable info on it. If I can find a cure this phone is going back. It obviously has a probem because there are many people who jave been having it. My phone is stock too.
[Samsung Galaxy Nexus] cmstlist:
I got your private message - it's probably best to keep your replies to the public forum.

If you haven't already unlocked the bootloader - I'm so sorry but there is probably no way to pull the files from your phone's internal storage if it can't be booted. I don't know if the wipe in stock recovery will erase the internal storage too, but I do know for certain that unlocking the bootloader will erase it.

I wonder why it gets corrupted like that on the stock ROM? That's very worrisome.
[Samsung Galaxy Nexus] GNMO15:
Boot loop

I believe it is most likely I will have to do a factory reset. I will hunt around in case I can find something more - it gives me the opportunity to learn and I was planning to unlock the phone at some point as a test platform for an app I am thinking of doing. I have Eclipse installed on my PC and was going to add the Android plugin but not expecting I will be able to do anything as the phone won't boot.

Cheers

[Samsung Galaxy Nexus] cmstlist:
I'd suggest trying the reset from recovery mode, just on the off-off-off-chance that it doesn't also wipe your internal storage.
[Samsung Galaxy Nexus] GNMO15:
Boot Loop

I am guessing there was an update that was being downloaded and installed. I recall seeing something about improved battery life in an update message but unfortunately I did not make any notes. I let it run through a number of reboots last night in case it was needed as part of the update process. Stopped by pulling the battery after about 8-10 loops.

[Samsung Galaxy Nexus] Wolfy666:
Exact same problem, continuous boot loop:

Google screen (4 seconds), black screen (2 seconds), vibrate, Google screen (4 seconds), black screen (2 seconds), vibrate...

GNex: factory image 4.0.2 (code.google,com/android/nexus/images,html#yakju)

boot loader unlocked but neither root, nor customer rom.

Only Google Apps installed - no other!

Thanks
[Samsung Galaxy Nexus] Sleuth255:
From your valuable info's perspective, isn't returning the phone worse than doing a factory reset? I'd try the reset first, load no apps and run a day or two to see if there's any change. Pita for sure but could provide some valuable info on this issue...
[Samsung Galaxy Nexus] cmstlist:
Since your bootloader is unlocked, you do have a chance of saving your internal storage. If you haven't already flashed Clockwork Recovery, you can do that from fastboot. Then in Clockwork you can mount data under mounts and storage. Connect by USB to your computer, get everything set up to make ADB work, and you can backup the internal storage to your computer:

adb pull /sdcard ./sdcard

As for apps and their data, that's less certain. You can try taking a nandroid backup from Clockwork. If it completes successfully, you're golden. Then you can use adb pull to yank those backup files safely off the phone. If backup fails on the data partition, then it's corrupted. You still have some hope of saving individual files but it may require some poking around with the command line and adb pull.

When I was having this issue, a nandroid backup failed at the data stage. I was able to backup apk files by pulling the /data/app directory, but an attempt to pull all of /data/data failed. I don't recall exactly why. But I was able to individually pull the directories containing SMS and call log storage.
[Samsung Galaxy Nexus] cmstlist:
Ever since the failures I had a few weeks back, I'm not taking any chances. I do a new nandroid backup almost every night before bed, and keep the last two available. But I still wish I knew why the spontaneous self corruption.
[Samsung Galaxy Nexus] davidstech11:
Other than an occasional freeze/lag typing on the keyboard the GN has been great. That lag while typing is rare too. This has been one of my favorite Android devices for sure. Hopefully those problems you guys have don't happen to me. Maybe its something you all are downloading.
[Samsung Galaxy Nexus] knome:
Here's a pretty consistent way to trigger this issue, at least for me.

Pull up the official twitter app. Press "discover" and try searching for something in the search field. Most of the time when you're typing, the phone just shuts off...

Curious if this happens to people running 4.0.3 and higher. Since I'm on 4.0.2
[Samsung Galaxy Nexus] GNMO15:
Wifi on?

Do you have Wifi turned on?
[Samsung Galaxy Nexus] Wolfy666:
Well, after:

- updating recovery CWM Touch

- formatting cache/dalvik

- factory reset

Nothing worked... still continuous reboot.

So I used the factory restore from the google code website and it's back working as before.

How weird is that? 4 months without any issue until this incident.

Good luck all.
[Samsung Galaxy Nexus] cosimoss:
Had it since day one and no.
[Samsung Galaxy Nexus] cmstlist:
The key to solving the "Google boot loop", when it results from data partition corruption, is reflashing userdata.img from the stock ROM. This wipes data and internal storage. Which is why I was suggesting how to backup everything else first.
[Samsung Galaxy Nexus] curious_yellow_eyes:
That could well be it. My nandroid failed when backing up /data, but when I wiped the phone with fastboot it worked (as I said I failed to flash Google s files. ) and has now 14 days uptime. that does point to /data being corrupted, no?

Although that doesn't explain why I had the exact same issues when I tried flashing a custom rom, thinking about it, as I wiped /data to do that...
[Samsung Galaxy Nexus] cmstlist:
I think that once /data is corrupted, Clockwork Recovery doesn't know what to do to fix it. Trying to wipe or restore from CWM results in an error because it's not actually fixing the partition. The low-level formatting that's required to fix it is only accessible from fastboot.
[Samsung Galaxy Nexus] dddnexus:
3G SIM ?

Hi all,

Gnexus GSM 4.0.2 from google yakju + bootloader unlocked + root

Observations:

My device just halts itself twice a day and I need to power on it. I don't have any App installed.

Reset/Reflash just don't work.

Then I removed my 3G SIM card and no halts after 3 days and counting...
[Samsung Galaxy Nexus] vulpy:
Hey mate, a lot of us are in the same situation with \data partition corruption problems. Do you still have it? Have you found a trick to fixing it or just swapped phones? Thanks, Vulpy

---------- Post added at 06:00 PM ---------- Previous post was at 05:59 PM ----------

Was thinking if there is any way to isolate the bad NAND sectors and avoid writing them? This would fix the issue. Any ideas how to do it? Thanks!
[Samsung Galaxy Nexus] cmstlist:
All I've been able to do is pull retrievable files over adb in recovery, and then reflash userdata.img which wipes data and internal storage.

For me I've only experienced this error running the Modaco 4.0.2 ROM. Once I switched back to stock rooted, I still had random reboots but no more corruption.

Until someone gets to the root of this - my advice is to take daily nandroid backups. If you get corrupted, pull your entire /sdcard over adb in recovery including the backup files, reflash userdata.img in fastboot, boot into the reset OS, copy all your files back, restore the backup. Takes a hell of a long time.

EDIT: And just to add a bit more insight, part of the trouble here is that an unbootable OS means all investigations and restoration efforts need to come over ADB in recovery mode. I'm no programmer, just a power end-user. What we'd really need is for a dev to be able to reproducibly create this corruption condition, investigate it, and come up with the least destructive solution.
[Samsung Galaxy Nexus] VladTepes77:
Hi there,

I must say, I am a bit disappointed, buying an official Google device and even though the OTAs are quite OK, there are errors (reboots) which are simply annoying.

My intention to use only OTA updates is nearly "broken" since I want to have a stable device with "up-to-date" fixes/functions.

I hope that Google manages to fix the existing erros, for me the reboots...

Just my 2 cents ;)

br
[Samsung Galaxy Nexus] biffsmash:
Mine seems to be less and less stable as time goes on. Stock 4.0.2, it reboots every now and again, and apps crash, mostly the messaging app and the keyboard, and the launcher restarts every now and again and I have to wait for all my widgets to refresh again.
[Samsung Galaxy Nexus] dddnexus:
GSM users can you remove the SIM card for a while to check if the reboots still happens ?
[Samsung Galaxy Nexus] b4cksl4sh:
I made some other observations but they seem also to be related to the SIM card.

I used my GN for about 2-3 months without any problems then one day i decided to take my old N1 with me because i was going to party big time (carneval in cologne/germany) and i don't wanted to take my rather new GN with me. Everything gets lost, broken and/or stolen during carneval! ;-)

So i removed the SIM card from the GN for about 48 hours and when i put it back the problems (random freezes in my case) started occuring.
[Samsung Galaxy Nexus] GNMO15:
SIM clue

I had my new GN for a 12 days went to another Nicaragua so bought a local SIM card, used it locally, came back to Canada put my original SIM card back in and boot loop started happening 8 days later. I have pulled my SIM card out 4 days and using it in my backup phone.

The GN still goes into the boot loop with the SIM card removed
[Samsung Galaxy Nexus] dddnexus:
My GN is about 4 days stable without the SIM.

Several Apps installed and all OK
[Samsung Galaxy Nexus] cmstlist:
Looks like there's at least three different issues being talked about in this thread:

1) Random reboots

2) Random freezes

3) Corruption of /data partition resulting in a boot loop that never gets past the Google screen.

Note that in my experience there is some connection between 1 and 3: I believe some ROMs, or some yet-unidentified things you can try doing while booted into the stock ROM, result in corruption of the /data partition when a random reboot occurs. In my experience, the very first random reboot I had running MoDaCo 4.0.2 GSM resulted in corruption. Whereas on stock rooted I get random reboots but no corruption yet (fingers crossed).
[Samsung Galaxy Nexus] yakalid:
Rebooted by itself once.

Rarely freezes because of some applications.
[Samsung Galaxy Nexus] THS1989:
Yup mine has done this a few times.

Google Navigation - Rebooted

Google maps - crashed needing battery pull

Also crashed or froze a few other times.

Hopefully updates get rid of the bugs.
[Samsung Galaxy Nexus] curious_yellow_eyes:
Ahh now there is a thing. My loop was getting past the Google screen, all the way to the unlock screen... but when I unlocked it froze, with the pattern still on screen, and the softkeys were not there except the application one. Pressing did nothing. Eventually it rebooted but it could take a long time to get there.

And the disappearing Market thing when and if it eventually did get to operational -ness.
[Samsung Galaxy Nexus] btoledob:
Hey guys.

I'm from Brazil and my Galaxy Nexus is the GSM one.

I suffered with unexpected shutdowns and restarts, especially when the device was in my pocket. This occurred several times a day, for weeks.

What solved my problem, finally, was this:

I put a piece of paper under the battery, holding her from the bottom, forcing the contact at the top.

After that, never had any problems. I did not know many people were going through this. It's been over two months that my phone works fulltime.
[Samsung Galaxy Nexus] fnord:
I wouldn't say regularly, but I have had a couple random reboots.
[Samsung Galaxy Nexus] zok-star:
random reboots for me!! stock non root :(
[Samsung Galaxy Nexus] matteventu:
I have the Galaxy Nexus (first batch production) with both 4.0.2 stock and 4.0.3 BigXie4 (now i returned to 4.0.2 stock) since 12 December, and it rebooted itself in total two or three times.

Accettable.
[Samsung Galaxy Nexus] deezid:
Since I've upgraded to 4.0.3 in December (now I'm using 4.0.4) no reboots. Before with 4.0.2 I've had at least 3 reboots in one week...

[Samsung Galaxy Nexus] curious_yellow_eyes:
I'm now at 19 days 2 hours 5 mins uptime (since I wiped with fastboot lock unlock ). I have all the same apps installed as before, except a different version of busybox. Maybe that is the problem? I used the stericson installer version previously.

Everything still stock but root.

[Samsung Galaxy Nexus] cmstlist:
20 days stable running stock rooted deodexed. Every time I had a random reboot I would cross my fingers and say "Boot! Boot! Boot" and it would boot into the OS. However today it gave in - I was just in the middle of reading a text message and BAM!

Fortunately I have gotten into the habit of taking nightly nandroid backups. So back to the usual routine... pull the entire /sdcard over ADB in recovery, use fastboot oem lock/unlock to reformat data, boot into the blank OS, push all my files back... and will nandroid restore data when all is done.

I wonder why it does this... power users can figure this stuff out but for this to happen to stock unrooted users too (which apparently it does) is just unacceptable.
[Samsung Galaxy Nexus] cmstlist:
You know, the last thing I did before the boot brick was plug it into my computer, delete one video, copy another video, and delete my oldest nandroid backup. Then I unplugged it from the computer, opened an app, received an SMS and... bam! Boot loop brick.

I wonder if some of our Nexii have a particular corrupted sector, that gets tripped once we've filled up a certain threshold of the internal storage... then it hits that sector and suddenly it won't boot.

Still that's a bizarrely vulnerable way to design a phone. I hope this can be investigated deeper so that a less time-consuming solution is found. Took me almost two hours to recover.
[Samsung Galaxy Nexus] EnIXmA:
In the past 3 months, my Gnex has rebooted by itself only twice. No freezing issues yet
[Samsung Galaxy Nexus] chlehqls:
As a potential new buyer of the Nexus, I am very surprised at the poll results showing a good percent of users having experienced a random reboot. I've never had anything like that with my previous phones.

Hopefully when I pull the trigger, I'll get a good one without the apparent problems that pop up in this forum.
[Samsung Galaxy Nexus] cmstlist:
I honestly suggest - based on the reports of NON rooted users having this problem - I now highly suggest anyone with a new GNex unlock their bootloader ASAP even if they don't plan on hacking. It provides an escape hatch to recover from the boot loop brick with less data loss. If your bootloader is locked and you're running stock recovery, please back up your internal storage frequently as the only way you'll be able to recover from the boot loop brick is to wipe.

[Samsung Galaxy Nexus] pdecat:
Last week, I have re-flashed the 4.0.2 (ICL53F) factory image and this time have wiped all data (I did a complete adb backup / restore).

Since then, my Galaxy Nexus has never rebooted by itself.

Looks like this problem was somehow caused by the upgrade from 4.0.1 to 4.0.2 without wiping.

Only had the one since getting my Nexus a week ago but I believe Green power premium was the cause, much as it was on my previous SGS 2.
[Samsung Galaxy Nexus] kalinf:
I would love to believe that fixed it but I did this 2 weeks ago and I had a random reboot yesterday.

Also I am currently only running the stock apps. This time it rebooted when I was using google+ other times it has been when making a phone call and writing an sms.

It happens so randomly that going a week without incident doesn't mean anything. I can go 3 or 4 weeks without it happening
[Samsung Galaxy Nexus] bryant_16:
I'm a stock user and I'm facing this random reboots. It happens out of nowhere, eg. listening to music and whatsapp and it just reboots. So far, I do not need to do a battery pull which is a good thing.

Just want to know whether does upgrading to 4.0.4 rom help in these random reboots?

Any 4.0.4 rom users facing random reboots too?
[Samsung Galaxy Nexus] chlehqls:
Are there more users who experience reboots stock users or custom ROM users? I plan on running AOKP right away as I'm a fan of Team Kang. Hopefully like I said earlier, I don't experience any random anomalies.
[Samsung Galaxy Nexus] cmstlist:
I've had random reboots on stock. I think the whole code base just isn't stable enough yet.

But because I've also had the boot loop brick issue in the past, every time I get a random reboot, I think "Boot! Boot! Boot!" and I'm basically cheerleading my phone to properly boot instead of bricking and going into a boot loop that'll require two hours of recovery work :-P
[Samsung Galaxy Nexus] Flukester69:
Only craps on me when I am trying new boot animations. I think I've pulled the battery twice as a result. In just regular use of the phone it's never crapped on me yet.

Pretty much this. I've had some great uptime runs of hundreds of hours. Sometimes I'll get a random reboot multiple times a day. Sometimes once a week. There seems to be no repeatable action.

I read that some people had this problem fixed after updating to 4.0.4, I will try it if it happends again.

Hard reset doesn't "solve " the problem, at least it didn't here... after a couple of months it's now starting to get a little flaky again.
