Nexus One Restarting Randomly! Help! - Nexus One Q&A, Help & Troubleshooting

Hey guys,
I was hoping someone here could help me out. I just got my Nexus one Today, and I am charging it as we speak. But anyways I was playing around with it while it charges and it randomly crashes and restarts on me. I already did the auto update over the air to FROYO, but it is still doing the same thing. Also it seems to do it mainly in apps that use the gps, for example the compass app will do it every time.
It took me a month to get this phone to me in Costa Rica, and it would be way outside my available time and budget to get it replaced. So I hope it is a software problem, maybe some way to do a swipe or something.
PS: I already tried wiping it from the settings options, but it didn't help. Also I would like to root this phone, but I am to afraid now as I don't know if there is a hardware problem with it.
Thanks for you help, it is much appreciated!

I think random reboots are standard on the nexus. Mines stock and I've had the problem since I got it. But it only happens every couple days or so so im not too worried. How often is yours rebooting?

No this is every 5min.
But I think I figured it out. First off I realized it only happened with sim card in. Then I realized it only happened when I forced the WCDMA, which I need for 3g in Costa Rica. Then I realized that if I enabled roaming, even though I am not, and Left WCDMA on forced, it also stoped. So that is what I did, and it has been going for 30min now. Fingers crossed.
I am still going to get the official Froyo and place it on the sd card then wipe in recovery and update. Just for safety.
So yeah Looks like software issue. Which is really good for me! If it keeps working I am going to root it soon, can't stand that white notification bar

Way, Way Too Many Reboots

Hola,
Dont know if Im over (ab)using my phone or if anyone else has the same issues.
My phone loves to reboot
-When I answer a call once in a while.
-When I turn off StreamFurious once in a while.
-When I disconnect the usb every once in a while.
-For no apparent reason every once in a while (ex. Ill find it turned off in my pocket or on my desk, but I never turned it off)
This happens about 3-5 times per day.
Also, on some of the StreamFurious reboots, it turns off and I have to pull the battery or it gets stuck on the G1 screen and never finishes.
Do you think I need a replacement or is this just a version 1 hardware thing?
Thanks in advance for your input!
We are going to need some more information to better assist you.
1) What Build are you using
2) Are you running Apps2SD
3) How much space do you have left on your internal storage?
Sure, thanks

Nothing crazy.
I wipe every time I flash.
I've tried factory resetting too.
I try to keep the system clean.

Something like this happened to me about a month or more ago. It was everytime I try and use my phone when I was charging it, it would reboot. After a few days it would just do it at random. I just called tmobile and they just sent me a new one out.
the same thing is happening to me. my phone randomly crashes/reboots and i was starting to think it is the Haykuro build im using. is there any way to test the hardware? is there something like that in an app?
help
Are you using ahome or someting like that cause those programs cause problem with 1.5 uninstall all your theme apps if you have any
No, no themes.
Called t-mob, since I've had the device (sans insurance) less than a year, they are sending new hardware without a battery to replace mine. I decided to add insurance to the new hardware just incase. Thanks for the input! Glad I called!
Now to virginize the phone... heh
I have the same problem. There's a lot of this going around. It sure seems like a coincidence that it started with Cupcake for most all of us.
This has been something that has been happening since the RC33 load it...
Now I got the stupid random reboot problem. This is a warranty replacement and my first one never did this. I guess I gotta get another warranty replacement. Anyone find a definitive cause for this yet?
almost 100% sure you have a hardware problem

I used to have the same issues WAAAY back after I recieved an OTA update from tmobile for rc33 or whichever one it was in march... back when I had still no idea what "cupcake" was...
always seemed to happen when I was:
answering a call, recieving a text while in a call that I started, etc.
but after I found out about the linux bit of my phone, I immediately cracked it... and... cupcake... and then? there weren't any reboots.... I wonder whats up with that? maybe something to do with OTA spls? I don't remember lol

RC33 was the OTA was in March I believe maybe Feb. This didn't happen as much on RC30 and then RC33 came out and this started to happened more often. Obviously it is not the ROM doing it as not everyone has the problem but something seemed to trigger it on some devices.

Going to have to agree. This is starting to seem like a Hardware problem, considering all the feedback we are being given.
I have the same exact problem.
It's definitely a hardware issue.
I was thinking it was because my extended battery pack is a little loose or some loose wiring. It happens when the phone is bumped a little. Like putting it on a table too roughly or flipping the screen up too quickly or it shaking in my pocket. Probably going to replace it.
I have this same problem...i had it originally with RC33 then it went away with the cupcake update and I recently root and install cynogen's build and its back to screw up my day
i don't think its a hardware thing ...at least in my case doesn't make sense to be gone for a month and then come right back after rooting
I also experience random reboot issue. Usually when the phone hang first then next thing you know, it is rebooting. Sometimes the phone will be just sitting there and it will reboot by itself. I always thought it is the ROM issue, never suspect hardware. I am running an old version of Dudes v1.3a build.
For me too
I am getting too many reboots too, just got a replacement phones(previous one did this too), same with this phone, first i thought it was Hardware but now it think its the roms. On hero it rebooted 3 times while booting the first time, on cyanogen it rebooted in a couple of hours, just dont know what the problem is, maybe abusing the phone
I got a replacement phone and still have reboots issue on it when booting, playing music etc.

Makes me wonder on the apps your using in the background or settings you have up, or even the ROM. Do you have any extra info whats up before it reboots? Does it choke out due to low memory maybe?

HELP XDA! Phone Reboot's if using 3g Data

Hey,
My AT&T rooted nexus one is still randomly rebooting if I use 3g data. I am in Costa Rica and the 3g is on the 850 band. I also have to add the apn "kolbi3g".
So basically I can use the phone for anything and it works great, but if I add the apn and start using the 3g heavily I will get a reboot, sometimes it will reboot vibrate 7 times and I have to pull the battery. I have tried 2.1 and 2.2 rooted and not also cyanogen 6 all the same problem.
If I do *#*#4636#*#* and select the wcdma only it runs the 3g better but reboots way more, sometimes the instant I place load on the connection. However if I select wcdma "unkown" the 3g works much better I can use it sometimes 30min at a time without a problem.
So any ideas what I could try? Is there a kernel that will up the volt's a bit just help stability? Or anything else I could try? Data roaming is off, I have tried both off and on, no difference that I can tell.
Thanks a lot this is driving me crazy! Just got this phone Sunday too sick to my stomach of the thought I spend $600 on this phone if I can't get 3g to work
How about radio image???
It is currently on baseband 4.06.00.12_7. Is there a more current radio?
I came across this multiple reboot issue on a (locked) Vodafone UK Nexus.
It booted into the OS (lockscreen) and as soon as data connected it looped back to the last couple seconds of the animated Nexus logo.... and again.... and again.
I powered down the unit (battery pull), booted into bootloader (voldown+power) and selected clear storage (voldown,voldown,power) then (volup) to confirm.
This deletes the user data and you have to sign in and set up the phone again but it certainly fixed the issue. My only guess is some user data became corrupt and the kernel panicked and forced a partial reboot.
Give it a try and lemme know.

Just did that (had the phone plugged into wall charger), and the second I got to the home screen it rebooted then vibrated like 6 or seven times. Seems to do it worse when it is plugged in. And now it won't even boot up even after pulling the battery, it vibrates 6-7 times.
I am really worried about this, any other ideas??? I will try anything! Thanks for the help
Update! Now the phone just reboot when I do anything period with it plugged in. Just like posted in another thread on this section!
Please any ideas I am very desperate and very sick to my stomach!
Hmmm very strange.
I'm aware from what you were saying on the other thread that you've got an unlocked bootloader and you're wondering what to do on the warranty front.
If you've really tried different combinations of stock and custom firmware and having the same issue I'm tempted to say its a hardware issue.
Many people have returned their unlocked phones with no comeback from HTC some have reported that they have noticed the unlocked bootloader and have issued a motherboard repair as part of the fix because of this.
Although im unsure of the additional cost (if any) i would definitely recommend going through the warranty repair route with HTC. They won't say no and send you back the same broken phone. And who knows, if its a confirmed hardware issue they may just replace it as a goodwill gesture.
Other than that I don't have any more ideas.
A nexus support thread has a popular answer referring to the clear storage fix.
http://www.google.de/support/forum/p/android/thread?tid=40f52d29e9c4177e&hl=en
Just make sure you are definitely clearing the storage FROM THE BOOTLOADER before calling HTC. It is the first thing they will make you do before accepting a return anyway.

Ok thank you so much sir. I am so glad to hear that I may still have a chance at getting it replaced! It was very fullish of me to unlock it, I know, it is just that I figured it was software and could be fixed by unlocking. It is going to cost me $$$ to get this to the States, but that is life. If I still can't get it to work I will call htc and let you know what they say
Little update here. I cleared storage again and just simply disabled data, I have been using the phone for a couple of hours on work without any problems. Next thong I am going yo yty is another friends 3g similar card and see if it still reboots on that sim, if it does then I am calling HTC.
Also still open to any other ideas you guys may have.

[Q] Why my Galaxy S locks up?! (Comatose Syndrome on going investigation)

Hi Guys,
Could someone tell me why my 2 weeks old Galaxy S (Service Provider: Bell) turns it self off out of the blue?
It happend twice already, the phone was on my pocket, I pushed the on/off side botton and nothing happens, the screen is pitch black!!
This is an irritating issue as I'm forced to physically take out the phone from the case and remove the battery and put it back on to turn on the phone.
Does anybody whats causing this issue? and how to fix it ?
Your help is much appreciated!
Cheers
Also, I was wondering if I do a factory reset to try solving the random shutting down problem, will I have to re-purchase all the apps I bought from the Market?
Send for warranty is needed I think

No, the info that you purchased the apps is stored in your Google account. So if you use the same Google account as you're using now as your primary account after reset, you can download all those apps for free. (Primary account is the Google account you first associated with the device.)
i had the same problem with 3 different bell vibrants. About 6 days ago, i bought a new sim card from bell for $5, and it has not happened since. I bought my phone from Bestbuy, but bought my new sim card from Bell store because perhaps the bestbuy sim cards are outdated. Hopefully it stays ok.
One thing i did notice was that when my phone would turn off by itself, it was always in an area where there was bad reception. Maybe a link.
I found that it happened when I installed a different launcher other than Touchwiz. I was using LauncherPro, uninstalled it and everything worked fine. I installed ADW and everything is fine so far.
I saw this thread yesterday and was thankful mine hadn't developed this issue. And then last night after about two hours idle time, my SGS switched itself off and the power button wouldn't respond at all. The only way to revive my beloved phone was to do a hard reset (i.e. removing the battery).
For what it's worth, the only "mods" I've made are installing a handful of apps. No new launcher, no custom ROMs etc.
I'm tempted to give Voda a ring and ask for a new SIM. But this really smells more like a hardware fault to me. A faulty SIM shouldn't result in a handset switching itself off, I'd think...
i'v encountered smailar problem , first i thought my phone turned itself off, later i suspected some apps i'v installed ( setCPU, autokiller etc), after while and digging, i found that i'v installed "Android Tweak" , it has an option to disable screen dim, and i'v used that option, so i changed it back and the problem is gone.
in Spain we have the same problem and no solution by now

Mine just died again ten minutes ago. I guess it's a possibility, but considering the number of bugs that we're all discovering with the hardware and software, I'm suspecting it's yet another dodgy batch of phones from Samsung.
I just bought two Galaxy S and I am having same problems with both. I called Belll and they said they never had this kind of problem before. I had installed few apps and thought may be those apps were causing the problem, but even after deleting the apps..phones are powering off itself...
Did any one find the solution yet??
Same problem here, and from what i am hearing is becoming frecuent among galaxy owners. Im amazed something this important hasnt made the news , i mean, its a huge malfunction issue .
I had the same issue.
I called up Samsung support and they asked me to do a phone reset. I didn't try that, but I upgraded the firmware and it's gone now. I suspect resetting the phone will also solve the issue.
This happened to me for the first time today as I woke up and it wasn't dark outside. When I looked to see what time it was my phone (that I use as an alarm) was off!!
This is the first blemish on an otherwise outstanding experience. But it is a major one. I will assume that it is somehow related to something I've installed. But I'm not looking forward to figuring it out, since I've got a lot of apps

Good luck. I did a factory restore the other day to see if that would help. It didn't. Like you I use my SGS as an alarm... I woke up two hours late this morning because my phone had switched itself off in the middle of the night.
I'm currently waiting for a replacement handset. I'm not holding my breath that the new hardware won't have exactly the same bug though...
Mine started doing this yesterday...same with a bunch of coworkers that have the same phone. We think it may be related to bad reception.
Sigh
My phone just started doing this in the last couple of days.
I've also noticed sometimes it gets into a state of continuously saying "usb debugging connected" and then "usb connected" and just continuously keeps displaying those even though it has no usb cable anywhere near it..
Havent flashed the phone for about a week now and it was fine for 3-4 days after the flash so no idea what is going on..
Anyone else seen those usb messages? They come and go.. but it seems when they come its usually when my phone turns off..

Thats funny...because the only time it has happened to me is at work, where the phone is struggling for reception. It has turned off a total of about 8 times over 1 month. It has never turned off anywhere else (except one other time i was getting bad reception in the forest, and a few minutes later it was off)...strange

[Q] Can't connect to internet, sync, etc. What's going on?

This is REALLY frustrating. I've been completely in love with my new Captivate for the past two weeks. It's worked extremely well, and been very stable. Not one problem at all, until now.
Just this evening, it decided to disconnect itself from the AT&T server (the popular 'connection failed' message. It has full bars, and can still make calls just fine. But it won't connect to the internet, sync my accounts, etc. It will also not connect over wifi, which I thought would work fine. I was wrong. It also isn't being recognized by my computer, no matter which mode I select. Even debugging mode isn't registering. I've rebooted the phone half a dozen times. Nothing. I've checked all network settings. Everything looks good. I've tried booting into the secret flash menu mode and resetting from that menu. Nothing.
Anyone else had this issue? What can I do to get this fixed? I need my phone back online for work asap.
If you are inside you 30 day window, return it and try another one. Sounds like a haardware failure, if you haven't been messing with flashing roms.
OMG I am having the EXACT same issue. My started this past Saturday. It will not for the life of me connect to the network. Its so frustrating...of course ATT has no solution to the problem exact sending me a warranty exchange....which I would rather not do, because it takes days to get the phone set up! ugggh~!!!!! if someone has any input in regards to a possible solution I would be forever grateful

I am by no means an expert, as I have only been a cappy owner for all of 3 days, but I have been doing a lot of reading and have been customizing my phones since the beginning of time, what exactly is taking days to set up? surely someone here knows a way to speed up that process for you.

I'm referring to getting it "setup" to my preferences..you know downloading apps, getting the widgets placed just so etc. Its all time consuming (for me at least).
I talked to a ATT rep who is "an android specialist" and she did a factory reset....which still sucks b/c I still have to redo everything on my phone.
Maybe it will help, fingers crossed. ..

how to fix turning off issue for samsung i9000 ?

I just have updated my mobile from 2.2.1 to 2.3.4, i used this forum tutorial - http://forum.xda-developers.com/showthread.php?t=1139050
I have issue - my phone is turning off for no reason, you know i don't have lots of apps only fb,twitter,skype and 'advanced task killer'
actually when I am doing Skype video calls, writing SMS or anything else my phone just changed to 'black screen' every couple hours and afterwards my Samsung turning off with sound. To turn on I need take battery off and then into back then he allow to turn on...
before I updated I had little bit similar situation, my phone had 2.2.1 version and i didn't have black screen, but my phone just had 'freezing' for 10 sec or more...
what's problem for? what's your suggestions ? thank you a lot.
Ed
I have this issue as well, although it doesn't happen as much since I upgraded to gingerbread. I did have it happen once the other day. I was listening to music and I needed to make a call and when exiting the music app, it froze. It then went black and I had to take battery out and put it back in. It's annoying if you got a otterbox case on it with two layers. I had heard updating to gingerbread stops this but so far I don't think it's 100%. I use my phone as my alarm and one time it went dead with a full charge and I was almost late for work.
Let me know if you figure something out.
what can say experts about our issue ?
I will take some day my mobile to repair centre.. it's sad if couple of people have same issue and nobody can tell us the problem reason.
Try to flash a custom kernel and see if it the problem is still there
can you tell me or give information what's is 'flash custom kernel' ?
I have also encountered this problem, very frequently if i may add.
the problem actually first occured a few months ago, after i updated my firmware to gingerbread.
In my case the phone does not freeze, the screen wont turn on or respond to any gestures (hardware/capacitive button won't too), however any running process still runs, in specific i can still recieve phone calls, or at least hear the ringer.
I know of many other people that encountered this problem, all came from different ROMs (MIUI, SH 3.5 and up, Stock, PilotX etc..) and i, for one, can say that in the past two-three weeks it atarted appearing a few times a day.
So - does anyone have any ideas for the nature of this BUG??
BTW I use the i9000t which i own for over 7 months now.
Same problem
Hi, I have the same problem here.
and have seen this myself on stock roms too.
It doesn't happen very often (only once on my phone for now) but it is getting me pissed off as no one knows the nature of this BUG.
could it be a problem with the latest 2.3.4 version ? or an update of one of the applications?
I don't have too many apps on my phone only skype and 2-3 games.
the only thing I can think of right now is that all people who had this bug had skype on the phone but I don't really think it's from that.
Hi, And-roid if u ll update to 2.3.4 your mobile will working deffo better, i suggest you update your mobile to 2.3.4
Hey eddys, i have 2.3.4 for over two months now, and the problem just go worst...
Hi eddys,
I have the 2.3.4 (and my brother and sister in law have it too with a stock rom).
this is happening on all roms and all kernels...maybe a problem with the 2.3.4?
I don't know but it is very weird, no one has an answer for this....
edit:
just checked this with my phone supplier and of course they have no idea what so ever about this bug.
come to think of it they didn't even know how to fix my brother in laws "problem" when the 3G internet didn't work (settings-->wireless and network-->mobile network--> check the V on Use packet data ) so no surprise there.
Anyone???
Maybe theres another forum that this problem should be posted at??
I have this bug too, but only while tethering. I've found a solution to the tethering related crashes - after you start tethering, go to the SuperUser settings, and disable root permissions for android wifi tether. Your phone shouldn't crash anymore.
hey zyczu,
unfortunately, I do not use tethering at all, do you suggest i should disable ALL root permissions?
This bug is really getting on my nerves!!!
Everything else, but this, is working great...
Since upgrading my i9000m to 2.3.3 through Kies, my phone has exhibited similar symptoms 3 times: freezing, not responding to touch etc.
The first time I had pulled the battery when it did this, but the 2nd time I had just put the phone down a minute or 2 earlier so display was off so didn't notice it(about 2 weeks ago). And the 3rd time(today), I was using it at the time, and so started taking off my rubberized case, only to have it restart before I got the chance to pull the phone back off.
Startup took much much longer than normal, which I recall the startup was similar during the 2nd "freeze & reboot". For some reason today, I randomly though maybe its an OTA update so I checked "Settings..About Phone" and found my kernel version listed as:
Code:
2.6.35.7-I9000UGKG3
[email protected]#2
I have no idea what it was before, but September 8th was 2 days ago... It is possible it said that before today's restart but no idea. I have a PIN on my SIM so when starting up have to enter PIN for it to work, but on these auto restarts I never got asked for my PIN so it could have restarted other times too without me noticing(ie. middle of night).
Hmm, mine used to something similar when I would leave Bluetooth on but would move out of range of a paired device. After a few minutes it would just shut down or stop responding. Haven't had that issue since moving to Milkys rom.
hi guys, i just used this tutorial http://androidadvices.com/how-to-up...0-to-stable-gingerbread-xwjvh-2-3-3-firmware/
first I installed 2.3.3 XWJVB then 2.3.3 XWJVH
just doing step by step...
my phone was working fine 2days then i had same issue and then I changed to original SAMSUNG battery and it's working perfect.
try this..
p.s. what kind of batteries you have 'original' or 'non-original' ? thank you
madmigs:
I did not notice the kernel version ive had before, however i took my phone to a service center today, and for what i can see i have the same version as you do, take aside the i9000t instead of i9000m...
eddys:
Ive been using different batteries orig/non-orig on and off, although since ive noticed it hurts performance i stopped doing that, do you suggest that this might be the cause of the problem?
If so, the factory wipe i just did (formatted the internal SD card) should do the trick.
try reading this it helped me since i turn the wi fi off when i go out
http://androidforums.com/samsung-galaxy-ace/312084-randomly-turning-off.html
Are you guys experiencing turn-off issue while phone is in the locked state. I mean you locked the screen and then after a while when you picked it up for unlocking it was powered off. If anyone has this issue, then I found a solution. Just let me know
my turning off issue went back and it's getting every time more annoying, I don't know what to do...
