[Q] Nexus1 rebooting loop problem - Nexus One Q&A, Help & Troubleshooting

my n1 having rebooting loop problem when i use it continuosly for 5-6mins or performing some task.in airplane mode i can use it for 30-40mins but then restarts and keeps restarting until i give it 3-4min rest before starting it again.probably this happen after 2.3.3 ota updat.

Wipe data (factory reset) and try again.
If it doesn't work - use "unroot/restore" guide in Wiki, PASSIMG with FRG33 image, test it.
If still reboots - use the warranty, something's wrong with your HW.
You can also look at the logcat to see, what is the problem that causes the reboot. Looks like something's overheating.

i am Having the same problem, i have unlocked bootloader and installed the latest cyanogen rom hoping the rebooting problem would be fixed but no luck ,,the rebooting or the overheating what ever causing it persist.
i don't know what else to try??!!!
i really like the phone and don't feel like buying a new one yet. nothing on the market right now convinced me to ditch my n1.
i am just sad that the hardware life span of of the n1 is 1 year only.

yah thats is overheating causing it.because when it becomes hot it goes into restarting loop until i cool it down.still dont know exact problem though.

Isnt the warranty void after you've unlocked the bootloader?

I had that problem when my CPU speed was over 1000. Maybe this'll help?

I don't think it's the cpu because since 2 days ago the phone started rebooting while charging without me working on it. so now i have to turn it off before plugging the charger, or it will hang on the x for hours.
i guess it's time for me to look for a new phone..too bad, i really like the n1.

yes nothing wrong withcpu its hardware problem.i also cant recharge it while on.
i keep it in fridge then it work fine.after little heat up it goes into loop again.

I've also had the rebooting loop when I had a bad battery fwiw. Changing the battery to a new one solved the problem.

I was having the same problem when it's charging (and I use the N1 a bit) and when I use the 3G data (surfing the web, installing apps from the market, etc.)!
And it's the 3rd time that I've sent my N1 to the Tech Repair!!!
Never repaired the first 2! I hope this time will be ok... I'm waiting for my Nexus 1 to come again with me...

This seems like a big N1 defect.
I called HTC today. Out of warranty repair in the USA is 55$ to 283$ plus shipping.
Could have bought a Nexus S for the 500$ I'm spending on repairs + devices.
*************
Update 5/5/2011
HTC fixed mine even though I unlocked the bootloader. No charge. Free overnight in both directions.

this is making me so much angry.although my n1 is in canada warranty but i am now in pakistan so dont what to do?even we dont know about the exact problem.is it board or something small problem?

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
Jf 1.5
Radio: 26I
No A2SD
31MB free
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?

New Nexus Not Working

Hello,
I bought a Nexus one and as I don't live in a country that sells it my cousin brought it to me.
The device doesn't work and self Reboots giving me 20 seconds of use.
Tryed working with/without a sim,
Did a Factory Reset,
Formated the Sd-Card on my Pc,
and still in the same spot.
any ideas on what else to try before giving up?
anyone had this problem and fixed it?
My phone is not ROOTed and is on Version 1 of 2.1
didn't have enough time to get other info like Baseband and stuff.
I'm not willing to root the phone.
** If i send it back it will make the phone very expensive as i will have to pay costums fee when they mail it back to me
Thanks in advance!
Sounds like a DOA. Really bad luck.
If you send it back you should not pay duty to get it back usually, unless you live in a very tax hungry country! Between US and CAN you would not get duty.
Beside try speaking with cust support, DOA are usually well handled by company and so far HTC seem to be handling repair quite well as per the few post about broken screen I have seen.
Did you try running the phone WITHOUT an SD card ? good luck!

If the boots, has never been rooted (boot unlock), no immediate physical damage, and has no signs of liquid damage or tampering (check void sticker).... it's likely just a software issue. Reload original firmware, or load a new firmware... Don't give up, sounds like the phone is still okay.

So it seems.
Where are you from, Krypton1984 ?
Looks like some rogue app is loading at boot, causing reset. Possibly corrupt ROM image - but not sure. Might be software, might be hardware. But here's one thing to try:
If you're on a T-Mobile-compatible phone (900/1700/2100), do yourself a favor and flash stock Froyo. No need to root for that. The guide is in the sticky thread. In case of corrupted ROM image it'll do the trick.
I think you should factory reset it. Maybe even download the official 2.1 rom and install it. See if it fixes it.
Try a battery trade in first. Believe it or not, my first N1 seemed dead, and support gave me a swap for a new unit. When the new unit came in, it was still "dead" with the battery that originally shipped with the device. A new battery is what caused my N1 to finally come to life. The batteries that ship with N1's have QC issues, because I was one of many to report a DOA battery in the Google support forums.
its brand new,
I didn't pay customs on the way in because my cousin brought it to me, so if i send it back i will and it makes the phone very expensive.
what if when i try to change firmware the phone reboots again without finishing?
i dont want to brick the phone.

Well booting to the bootloader will answer the hardware software question.
1. Turn off the phone.
2. Now press (and hold) the Trackball and turn on the phone.
Once you're in the loader let it sit for a while. If it stays up it's a software problem and a new ROM should sort it out. If it reboots while in the bootloader it sounds like a DOA phone.
Good luck.
You can also try a full factory reset through the bootloader. Search for the instructions as i do not know them off the top of my head

i am having a similar issue. The phone reboots randomly and gets stuck at the static X logo screen. i have to remove the battery and let it be aside for at least 10 minutes before i am able to get the phone up and running again.
i tried updating to froyo. it installed but then froze up again on reboot. i did the battery thing and then started it up, went on fine..froyo had been successfully installed, but my random reboot problem STILL DID NOT GO AWAY..
can this be sorted by installing the original rom image?? or do i have to go in for a swap?!?
i don't want to swap coz they send out refurbished devices,,but its the last option...

You'll probably need to swap based on what you're saying. I, though, actually think Refurbished devices are just as good or even better than new. Think about it, if you keep getting dust under the screen maybe a refurbished phone will already have the fix? For that scenario it works out.

I really think this is a bad RAM issue.
I had this happen to my Nexus (ATT). It was prior to flashing froyo. I tried everything, flashing back to stock (including radio), cyan's latest, Paul's (stock) Froyo (with and without radio). Same result. Seemingly random reboots.
I thought initially that it was a software issue - It would not reboot while in fastboot/Amon's Recovery. But having tried every software combination, I've concluded that it MUST be hardware, unless I'm missing something big.
The phone, for the most part, would be fine as long as I DON'T TOUCH IT. It would stay idle for a long period of time (24hrs+), then I would use it Everything from web browsing to downloading apps to making calls, and it would reboot. It's frustrating because it seems that it's rebooting for no reason except that I'm touching it.
Sent in for a replacement, it arrives today. Hopefully it will not suffer this problem.
After talking with HTC they told me i need to swap the phone.
Because i'm out of america i need to send it to someone in the US amd then they send him the new divice after he sends my old one,
I am not satisfide with google's (first guy I talked with) and HTC because none of whome understand the severity and the hard feeling of getting a BRAND NEW IN BOX paper-weight. nothing about we'll compensate you or nada.
For me it tells me the brand is not strong enough to manage an outer state service and i wouldn't recomend them for countries that they don't cell it for.
If you where born in a HTC GOOGLE compatible country enjoy!
As i'm am probably less lucky and still in 2010 nationality counts

Nexus One boot problem (freezing)

I received a Nexus One yesterday. First it worked for around 5 min, then rebooted by itself. From then on I never got into the system. If i turn it on normally, it freezes (or loops) at X logo. I have no problem reaching FASTBOOT and BOOTLOADER. But when I try to go to recovery, sometimes I can get to it, sometimes not (freezes at X also, or the screen is completely black so I need to pull out the battery).
What is causing the problem? I also tried to flash recovery image, same result. As long I'm a newbie, I know nothing about radio, spl, kernel ... flashing and dependencies between each.
Is it possible that it is a hardware issue? If not, what can I do, wipe, flash, etc...?
In desperate need of help... Tnx
I had exactly the same situation with my first N1. I called HTC and returned it as a defective device. My replacement device has been rock solid.
That being said, can you get into recovery Mode? (hold trackball down while powering on), if you can, try a factory reset and see if you can boot then.
Yea sometimes i can get to recovery mode. Usually when the battery is out for a while. I tried also with the factory reset, no success.
I write this problem here thinking there may be a solution (like flashing everithing...), but the problem is I know very little about all the stuff such as kernel, rom, radio, etc.
Any advice besides returning to HTC? Because I have no warranty.
You describe my problem exactly. It was a hardware problem and I returned my device to HTC.
It sounds like the same problem i have.
Looks something like this ?

This is happening to my N1 quite often, it seems stable now and doesn't happen often. I am guessing it has defective RAM or something.
The important part of this is how long did you take to get your device back as I see you are also in Canada, this is why I am not sending it in also, I know they are pretty good about honouring the warranty after root if it is hardware but I don't want to send it in for nothing if it is not that bad.
I have started using a 950mV kernel, this seems to have helped. Try one out OP.

Random Restart and Boot Loop when Plugged In (STOCK)

So I was hoping that anyone here could shed some light on an issue that one of my friends who just bought a Nexus is having. His N1 is bone stock, and is an AT&T model. Every once in a while, completely out of the blue, the screen will turn black and restart, but then enter an infinite boot loop, where the only solution is to remove the power adapter and battery.
In trying to pinpoint the problem, we have noticed:
-It really only tends to happen when the device is plugged in.
-It's not related to the battery, charger, or microSD (since we tried mine to no avail)
-It's probably not kernel, ROM, or radio related (we let it do the OTA 2.2 update, and the crashes were still present)
I don't understand why it only happens when the phone is plugged in. The phone isn't hot to the touch, so I doubt that the battery is over heating.
Any help will be greatly appreciated. Thanks!
PS. I tried searching, but the only mention of boot loops I could find were on custom ROMs and Kernels...
Exact Same problem and Phone here!!!
Just got it today too! Please any suggestions would be nice! Want to root this phone but to afraid there is a hardware issue!
My friend ended up calling HTC and they asked him to return it, which he did, for a full refund. Ironically, he ended up getting a Samsung Galaxy S (ATT Captivate variety). Nexus one, although less powerful, is more sleek in my book...
I've got almost the exact same problem on an AT&T N1 running Froyo FRF91, the two differences I have are that the phone does feel hot to the touch, and that it never happened on 2.1. If anybody has some info on this it would be greatly appreciated, but I will be calling HTC/Google in the next few days to see if we can resolve this problem.
Hey guys,
I had a very similar problem with my phone rebooting while charging especially on the Car Dock. I ended up doing an exchange with Google/HTC and received another unit. This one now has no problems with rebooting. I suggest calling and getting your units replaced. My guess is there was a bad batch that have hardware issues.

What can I do if it is unlocked? Any chance they still help you out? Or just forget it?
I don't think it would hurt to just give them a call. I have read some forums where people have sent unlocked phones in for repair and then got them back fixed and re-locked. It is worth a shot instead of having a faulty phone. I did the exchange option and it did take me a while to get my replacement phone, but that was due to HTC moving their repair facility according to the tech. The techs that I have talked to have been helpful. If I thought a tech was no good I just hang up and try again with a different person.

I have been having pretty much the exact same issues.
I have an AT&T unlocked/rooted N1.
Random reboots frequently when the phone is charging via plug or USB for seemingly no reason. I thought it may have been an app, or combination of apps, so I tried a combination of different steps to try and find a solution.
Wiped data/cache
Wiped data/cache & fix apk permissions (Amon Ra 1.7.0.1)
Wiped data/cache and flashed the current ROM I was using again
Wiped data/cache and flashed different ROMs (both 2.1 and 2.2 w/proper radio) including MCR r16-21, PhoenRom, LeoFroYo, Cyanogen 5/6 RC1 and even tried intersectRaven's Kernel's
Reformated the SDCard both via gparted from Ubuntu live cd and Amon Ra's recovery 1.7.0.1
Swapped out the SDCard thinking possibly a bad block
And finally re-flashed back to shipping stock 2.1 and stock recovery w/successful OTA 2.2 install
All steps I was able to get my N1 to randomly reboot plugged in or not. I even had it sitting on my desk at work unused for 30-40 min (running CM RC1) and it rebooted with no user input what-so-ever. It happens more often while plugged in but was not limited to charging state.
All that said, I finally called support, took about 30 min total to arrange a replacement. This included a factory reset while on the phone with the tech and I was able to get the phone to reboot within a few minutes of first boot.
Take it for what it is worth, but I am positive that this is a hardware issue in my case. Just hope my replacement goes without penalty (unlocked and all) and that my new N1 doesn't have the same issues.

[Q] automatic random reboot

hey all,
i got my galaxy note now 3 weeks ands it's rebooting random all the time. at a service point i let them do a factory reset but that did not work. does anybody know a solution for this problem? because i dont like to send my note cause i will not have a few days sow if anyone got a solution i like to try it.
Gr Sven
Suffering from the same here
I think its related to one of the apps - I will start removing my installed apps one by one from tonight - Will keep you posted with the updates.
Also, if anyone out there had the same issue; please advice!
I had the same issue on previous android devices..I managed to get around it with numerous hard resets. Also I believe that a certain combination of apps will cause it too..but i don't know which ones. I've got a dell streak right now, and its been stable for a few months..having said that, it still randomly reboots once in a while but no where near the consistency it used to.

I had this problem too and it seems to be an installed app problem, particularly any that change the wireless settings in some way or apps that stall when accessing the external SD card at boot times.
this is exactly what happens to me guys, same problem.
Random reboot and this happens all around the clock, no matter if it is day or night or if the phone is in flight mode...
Frankly I don't want to uninstall my apps one by one to check what app is causing the issue because I have no time to spend on it...
I hope that someone with more software skills than me (I am just an user) will succeed to fix it...
cheers.
Do you have Dolphin browser installed?
If it's the case, don't search further...
What's the problem with dolphin browser? I constantly use it and never had a restart. Is OPs phone overclocked or undervolted?
Which rom and kernel are being used?
mine is also rebooting every once in a while for no apparant reason. Mostly when I unplug it from the USB cable but not always. This happened from the first day on. I never did a factory reset but considering it now since the SMemo app is not working anymore (no strokes are visible) and I am out of options.

Dolphin is a well known app for causing random reboot, since SGS 2.

I think it's the SD card causing these problems.
My reboot problems all disappeared when I removed the 32Gb sandisk card. I replaced it with a 16Gb card and was very careful about which apps I installed on it. Now whether it was the card size/brand or the selective apps that resolved the issue I can't be sure. Having Dolphin's cache on the phone memory instead of the SD card might also be a solution.
But it's worth investigating if you have reboot problems with external card installed.
Hi guys,
As soon as I got my Note, I rooted it and flashed a custom rom. Never had problems with reboots so far.
So, for a change I though setting it beck to stock was a good idea, with the upcomming ICS update.
As soon as I flashed the stock rom with odin, and it was back to factory situation, the reboots start happening. Every 3-6 hours the Note rebooted. Got in contact with Samsung (NL) and suggested to execute a factory reset, so I tried that a couple of times. But no luck, the reboots keep happening. I thought maybe it was an hardware issue. I have no Sdcard, only my SIMcard, which was a bit warn out, so I order a new SIM. But still, the reboots keep happening.
Then I decided to root my device again and flash a custom rom (Rocket-Rom), and guess what? No more reboots!!!
I hope this helped.
To me, I think automatic reboot is somehow still acceptable. I experienced two times auto power off. Both were happened after I charged it over night, unpluged the charger and left it without unlocking the screen, drove to my work place, and found it dead
I'm only having it for 2 weeks and I haven't rooted it.
it maybe a usb charging issue which is causing so much grief to many note owners. Mine has a defective usb port and it makes my note go crazy, including reboots and makes the note think its charging when its not even connected to charger at all.
Using note since dec... Faced such problem 5 or 7 time whn my phn was nt rooted... But nw its working fine... Using rocket rom v 20...
