[Q] Nexus One Random Reboot Crash (logcat)

Hey all.
Been having problems with a Nexus One that crashes at seemingly random times.
I have been unable to pin it on anything, and am asking your help.
It appears to be independent of the Rom installed, whether there is an SD card present, or whether its connected to a USB cable or phone charger.
Any help would be greatly appreciated.
Phone Info:
Nexus One (AT&T model)
Radio: 4.06.00.12_7
Current Rom: Enomther's TheOfficial Nexus1 - v2.12.2
Provider: Rogers (BC, Canada)
Logcat output attached as screen capture image.

This has been reported by a few users. I sent mine in for repair and got it back not repaired - they couldn't replicate the problem.
My case has been escalated which means a HTC guy called and asked me a few questions and then told me to wait for an email (a few days ago).
I believe my problem started when I seriously overheated it ... driving with navigation on, 3g downloading maps and traffic data, car charger plugged in all on a very hot day on a very hot dashboard. This was the first reboot and they got more and more often after that. Now I can't run anything for more than 5 minutes if 3G or wireless is on (in 'Airplane' mode I can run for quite a while without a reboot).

mine was doing the same thing.
getting progressively worse until the phone was basically unusable earlier this week.
I was running CM6 at first when it started happening.
installed the newest nightly and it worked better for a bit then got even worse.
uninstalled the stand alone version of gmail from the market and it worked for a couple hours and then kept rebooting on me.
finally i did a factory data/cache wipe and installed a rooted stock rom and things have been working PERFECT for over half a week.

I had the same issue. first reboot happen when i had nav running plunged in then after a few months utube , browser etc would restart my phone. it didn't matter which rom i used or stock. I sent it in and they fixed it. i had issues with htc but it got fixed.

Yup, same here, strange thing is it isn't a complete reboot. Hard to explain but what happens is i'll touch the phone and then it will immediatly go to the CM6 boot logo, then immediatly to the lock screen, (which I have disabled) then to my normal desktop. Total time elapsed maybe 5/6 seconds, wierd.
A normal reboot usually takes about say a minute or so. just started happening 3/4 days ago, and happens maybe twice a day at most, some days not at all. Probably wait until Cyanogen includes 2.2.1 into 6.0.0 stable then reflash.

Ive been having the same problem for about a week now, but I'm still using stock, not rooted. Its weird, because its a really fast reboot. It goes to the Booting X, for about 6 seconds, then it boot up just fine. I cant understand it.

this really sucks
I am keeping my ATT nexus one around for gingerbread but these random reboots are really killing me....I use the phone for five minutes and it just reboots by itself....The phone runs really well for those five minutes...Ive done five factory resets but it is still just doing these phantom reboots.... Anybody find out anything more about this...or know a fix....the phone is not rooted and it is clean stock froyo...so please help or keep talking about it so htc will address this issue lol which i doubt since this phone is starting to become ancient....(cant wait till nexus S) =P

With regards to the original problem posted, I believe I've managed to diagnose it correctly.
The problem lies with faulty heat distribution. The phone would crash and reboot more often in times of great stress:
charging the phone (heats up the battery)
running many applications at once (heavy system load)
navigation (heavy dataand gps traffic, image processing)
This coupled with the fact that changing the OS did nothing to remedy the problem solidified the notion that the problem was hardware based.
Given this, I contacted HTC Nexus One support and had the phone repaired.
Note: HTC will honor the warranty and fix hardware issues for an unlocked Nexus One. With software issues, you're on your own (for obvious reasons).

This is exactly what my phone is off to warranty for. I experienced this with every rom tried. I wipe my phone completely and put stock froyo on only to see the exact same behaviour...so at least I'm not crazy
The tech told me it was a hardware problem so that is a bit of a mind ease.

It seems Nexus One and Desire are really similar: HTC Desire rebooting on its own.
P.S. It's a problem with faulty motherboard, if you're within warranty, it should be replaced.

I also have been pleasantly experiencing this issue with the nexus one, so i sent it for repair at HTC and they have said it is an issue with the motherboard and it has been replaced, it is now in the post so I will update this post when I receive it to whether the problem is resolved. Hope so was driving me crazy!

The log did not capture the error. In most cases its a software issue, not hardware. (has happened to me too, not recently though)

Well an update as promised.
I received my N1 back after UPS had finished not dispatching it due to "Adverse weather conditions" and the issue is GONE!!! I know a week isn't really a long time to trial the device but this was happening several times a day.
HTC replaced the motherboard.
My advice to anyone having this problem, is to send it to HTC for repair (dont be worried about it being rooted/custom ROM etc mine was and because its a known hardware issue they really aren't bothered about it.)

It took two trips to HTC for them to finally address the issue. They did fix something (they didn't say what) and the problem is gone.
I believe it was the motherboard because Swype Beta decided that it was a new phone and not the one I registered (so it would not install).

Just found what app was causing random reboots, may help you too

Making long story short, I have the phone about month now, unlocked,rooted, heavily modified, upgraded to .57 using it overseas.
My phone was just fine until it started rebooting itself, sometimes twice a day,
two weeks ago.
After spending a few hours finding the cause (It's not easy when having 170+ apps), I realized "more locale 2" with custom locale was causing the troubles - changing it back to defaults and removing the software helped me and I didn't experience reboots ever since for the last few days.
May not help you if you had reboots from day 1, may help others with non faulty hardware, just my 2 cents.

We heard that hard reset have occurred on Droid X.
We'll be researching this problem. And don't use this app to Droid X now.

Maybe thats the reason .. Motorola devices .. send email to the developer, tell him that.

i use this app every day and haven't had a single reboot on my phone ever

constant system crashes

Hi there,
I bought my Galaxy Note one month ago and in the first weeks I never had any problems with it, but recently it crashes more and more often. A week ago, while I was still on stock rom (unrooted), it crashed 5 times at one day. I did nothing that could be a problem for it, I was sketching (Autodesk SketchbookMobile), browsing, playing games etc.
I thought it may be the best to try a custom Rom, so I rooted my Note and flashed RocketRom v20. But soon after that the same problem appeared, and besides that, I needed after every crash more than 10 trys to successfully start the phone, somestimes it stuck at the "Samsung Galaxy Note" logo, sometimes it even accomplished it to get to the PIN-input, but crashed at it.
Yesterday I flashed RocketRom v21, but nothing changed.
The only thread about crashes I found in this forum says it may be because of S-Memo, but I barely use it, and never had problems while using it.
Right now I'm holding my Note in my Hand and try to start it, it's attempt 30 or so. I really love the Galaxy Note, but this makes it hard to use for me.
I appreciate every attempt to help me.

seems like manufacturing defect. If you are able to enter download mode, then flash Stock ROM which is latest for your region. then go for a replacement.

A few minutes ago I wasn't even able to get to downloadmode or to charge the phone, but after I plugged it in and out a few times I somehow managed it to get to download mode. I flashed the stock Rom, but the phone again stucked at the "Galaxy Note"-Logo the first two attempts to start it, now, again, it shows no reaction.
It seems like I have no other choice then to send it back

Sounds like a hardware defect with the internal NAND that might be accounting for the random freeze/reboots. Bad RAM can also do this.
Bad/ Corrupted sectors can do that. Lawl.
Also, list all apps that you've installde from the market. There might be some conflicting processes that's causing the phone to hang.

And first to be sur take your sdcard out, and test sometime bad/defective sdcard can also have dramatic effect.

It's already on it's way to Amazon.
I tried starting it without the sd-card, but that didn't help.
I hope it doesn't take too long, because i can't handle the tiny screen of my Samsung Wave anymore.

You are not the only one with this problem. Mine also started crashing/turning off randomly after approx 1 month of buying. Again on stock rom unrooted and very few apps installed.
Starting to think that just maybe samsung have tried to push the boat out too far by releasing this device. Don't get me wrong I love it (when it works) but it just seems too buggy atm. And I don't think ICS will cure all these problems we are all having. I know every device has a small percentage of faulty products but it seems that the note has a high percentage of those.
Sorry to be so negative but when you spend 600 euros on a phone you expect it to work for more than a month.

Working solution for random boot issues

So this morning I got a call from a friend who told me that his TF is running like crap after doing OTA upgrade to ICS.
We met up at school and I got to take a look at it. Yes, it was indeed running like crap and it even randomly rebooted while we were eating breakfast. He told me the random reboots were happening every 3-5 hours(that he could notice).
Here's what I did to fix it.
Removed his MicroSD card(not sure if necessary)
Shut down TF.
Hold [volume down] and [power] button together until you get into reset mode with 2 icons in the center of screen. Left icon is Wipe Data. Right icon is Cold boot. Right icon is selected by default.
Press [volume down] to highlight the LEFT ICON, which is Wipe Data.
Press [volume up] to confirm your selection
Go through the process.
Let your TF reboot.
Shut down TF again.
Hold [volume down] and [power] button together until you get into reset mode with 2 icons in the center of screen.
You need to do cold boot. It's already selected by default so just wait like 10 seconds and it will happen automatically. Press [volume up] if you don't want to wait.
Go through the process. Your TF will reboot afterwards.
Done.
It has been over 24 hours and his TF has been running smooth without any glitches or any random reboot. I told him to let me know immediately if a random reboot happens again.
This is simple to do. Worth trying unless you can't read English.
Edit: I didn't include this at first because I thought it would be common sense for everyone but it apparently isn't....
DO NOT JUST RESTORE ALL YOUR PREVIOUS APPS AND WIDGETS YOU HAD FROM HONEYCOMB. THAT DEFEATS THE ENTIRE PURPOSE OF DOING A RESET AND PREVENTING APP INCOMPATIBILITY.

thnx man for sharing . I actually tried every thing to solve this issue but no luck , I'll try your as sson as i go home .

This did indeed work for me as well. I tried this a couple days ago and I have yet to have any freezes or random reboots. I think that not restoring any backed up data, apps or settings is key to fixing the problem. I'm now very happy with ICS- burn in hell Honeycomb.

Shameful bump

When you switch from a version like HC. This is what you exactly should do!
I did this and never experienced random reboots.
My Transformer is running since three days and everything works fine!
Edit:
Another quick hint:
If you want to work with Google Docs, you have to disable Forced Hardware Rendering!

I see on forum the problem is google+
So I removed google+... Wait and see...

.....lol, why post in this thread that you are not going to follow the advice of the Op?.......

Sorry to say but this is not working, already done this since the minute it was out and still have so now and then a hang boot
(random reboots that hangs on the boot)

Giving it a try
I am experiencing random reboots after ICS
Wiped transformer, cold booted, and installed the following.
Adobe Reader
Dog Catcher
updated G+ and GMail but have not run it.
Charging now, I will let you know.
Previously I had wiped it and reinstalled all, disabled syncing, disabled location info, adjusted wi-fi settings, and added CPU throttle control obviously none worked.

It might have helped some people, but it did not help me. Unless it was dogcatcher.
5 or so minutes after unhooking it from the charger, I tried to wake it. And it was unresponsive. Was only able to wake it by holding down the vol down and power button at the same time.
I will kill off Dogcatcher and try again but it is not looking so good.

why are you installing dogcatcher? And this does work.. do it again. Don't install your apps.enusre it dos not lock up before you install anything.... If it locks up before you install any apps then call Asus. If not start installing one app at a time. Wait after each install. Ensure that its not doing it, once you are sure install Another ....rinse/repeat....

I installed dogcatcher because I needed something to listen to on the way in to work. I have uninstalled it. But I doubt that is the issue.
I have had these sorts of reboots on my Transformer until the third or fourth Honeycomb update. But eventually they fixed it. I suspected this would happen again.
Considering that dogcatcher one of the most popular podcast apps on the market I suspect that there are many people with no problems using it just fine.
But since I need a podcast listener to be able to use the device as I want to, does anyone without issues have a podcast listener that they use?

2 hours into the last experiment and it died again while sleeping.
So that about sums it up. This procedure might help with some issues Transformer's are having but not all.
Recap. Wiped, cold booted, gmail setup, G+ updated still equals failure.

I love how horndroid 'solved' this issue and then goes on the belittle people who are still having it as 'stupid', and probably their own fault. Horndroid, I appreciate your attempt to contribute, but your attitude and stabbing-in-the-dark protocol is not becoming nor helpful to anyone. Definitive statements pertaining to ONE TF101 device that you own are quite naive, there are several different models, and until you have personal access to each model version you should advertise your 'solutions' as "worked for ME", and understand if it doesn't work with others it isn't THEIR fault..this is not a blanket solution for every device's reboot problems. In fact, I am willing to bet the reboots being resolved by this method are of an entirely different genesis than the reboots that I and others are experiencing (hang-boots).

I hear what you are saying I have the reboot issue as well.
I did a reset before and after and only installed xda HD and ran it for 2 days and got 3 reboots so I did the cold boot and then it did it 2 more times that day. Earlier today I almost couldn't get out of the boot loop, so I wouldn't say its a app problem its something wrong with the firmware somewhere

Some aren't too lazy we just don't want to wipe data after every update. I think i have gotten 4? OTA updates and 2 of them screwed up deep sleep while docked. Guess what the first trouble shooting step was...wipe data. Guess what worked...the next OTA. I don't have time to read through all the different threads on the same subject but are people that flashed through cmw instead of ota having the same issue? My buddy went this route and has no issues.

Can't read horndroid's "advice", because I have him on ignore for trolling, and have done for ages. From the tone of other posts here, it seems the "solution" is to wipe; if that's actually the case, it's total BS.
I wiped immediately before upgrading to ICS, wiped again afterwards, and have put almost no programs back on. I am and always have been on stock firmware and unrooted. I had no problems with boot loops, no problems with lockups, and only extremely rare problems with spontaneous reboots using Honeycomb. With ICS, I have had all three problems in a matter of days, and the lockups / spontaneous reboots are fairly regular (1-2 times per day.)
This is a problem with the stock rom, not a user app problem.

I reported him for verbal abuse and foul language. His attitude is not helpful, and if I were a mod he'd be gone already to think long and hard about his conduct. Anyways, taken your advice and blocked him. It is obviously an issue with the ROM, I'm beginning to think it has something to do with deep sleep, others posited that it may be media scanner, maybe combination of both? Maybe these two events are trying to happen at once and it doesn't like it.. a stab in the dark at least..

It's hilarious how you think YOUR problem is the only problem that everyone is experiencing.
For a lot of people, it was the app incompatibility that was causing them issues.
Obviously you think your problems are caused by something different, but that doesn't mean there are different problems caused by other reasons.
While all of you are speculating, at least I've posted a solution(even though it's merely doing a data wipe and cold boot, pretty much common sense) that has been proven to work for a lot of people. I've never claimed it will work for everyone; just those having problems due to app incompatibility.

I'm pretty sure this is an issue with the update itself and all these "fixes" are going to be pointless in a little while when an actual fix is released by Asus.

[Q] GT7510 32gb keeps switching off

Hi
Has anyone experienced that the tablet switches off constantly with out any any specific reason?
I could easily surf or read an email without switching off.. but then i would watch a movie and it switch off instantly or the other way around and its not even shutting down.. it just goes from powered on, to completely switched off.. It does not get hot and it does charge perfectly and the battery level does not drop/discharge radically.. it has never been dropped or manhandled. and it started doing last week
I'm on stock 3.2 PDA:KMP CSC:KMP (XAB), not rooted..
Any ideas, suggestions?
Thanks in advance

I suggest you to discuss your matter from where have you bought the notebook as there might be some problem in hardware

Thanks

I used to own a Galaxy Tab plus 7.0, which experienced this known problem of random reboot and/or sleep of death. You could google that to find out more.
I've since returned it for a refund. Then I picked up this used P7500 a month ago. It has not experienced not even one reboot. Sure, apps do crash from time to time, but the OS never completely froze.
How long have you owned your unit? If relatively new, I would returned it. If for a while, and only recently you experienced the problem, then I would do a factory wipe, or at least re-trace your steps and uninstall the last few apps. Also, ask yourself whether the problem is already related to certain apps. If so, get rid of those apps.

hi
Did a complete wipe.. so now its close as possible to factory default..
Could it be a battery calibration error? it works plugged in to either pc or wall socket.. works 10min after but then switches of randomly
Thanks for all the help/suggestions so far really appreciate it!
I know some mentioned the option of returning it.. But its bought in the US and im located in Denmark!
