Reboot problem - Nexus One Q&A, Help & Troubleshooting

Hey guys, I've got a problem and am hoping the minds at XDA can help.
My brother and I both have a Nexus One and both have unlocked bootloaders. I've never had a problem installing custom roms or restoring back to the shipping rom, or suffered any problems whatsoever.
However his phone, suffers random reboots all the time. I unlocked his bootloader and from the very first Rom we had problems. I double-checked my methods and even tested it again on my phone with no problem whatsoever. So, he got back into town today and I restored his phone to the shipping rom (userdata, boot, system, radio, etc.) It still randomly reboots. I thought it might have been a bad battery and swapped it out with a different one, and I was able to mess around longer with the phone, but it still rebooted on its own accord.
I told him he could call HTC, but more than likely he would have to pay 180 dollars to replace the motherboard on the phone. He says he'll just deal with the random reboots instead of the possibility of paying the money.
Does anyone have any suggestions as to what the problem could be, because after reflashing the shipping rom I'm out of ideas. Another odd thing I noticed with his phone from the get-go was the haptic feedback and vibrations in general, they were barely noticeable, almost non-existent as compared to my and my friend's nexus one.

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

Yeah, North America is all one big happy family. We've got NAFTA and everything now.
OP, I am assuming you've allowed the battery to charge full?

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

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.

reboot loop

I used to have random reboots on Nexus One, but after updating to Froyo 2.2 (before the official release), I had noticed the random reboots to get more (like 2-3 a day), but now the phone is totally useless, it does reboot constantly, and when it's connected to Power, it reboots couple of times, then gets stack at the Nexus logo.
I have put the stock firmware back, EPE54B, and it even detected 2.2 and Google pushed me the official release and still no go (yes, I did clear cache, etc)
I loaded up the log program and checked the logs after a reboot to see if it was some sort of kernel panic or something, but it does not show anything per say.
I even tried w/o SIM or w/o memory card and the results were not conclusive, it worked for some time, then started rebooting on its own. Sometimes I notice the phone is very hot, which makes me think that it might be faulty hardware (ram, etc)
Has anyone seen such an occurence, would HTC repair the device now the bootloader is unlocked or is this just a thin paper weight ? I think I read someplace that they still honor hardware repair...
Thanks,
Houman
Mine reboot when it overheats during charging. There are several overheating threads u should check out.
Sent from my Nexus One
Just be honest

From what I hear, if your honest and tell google that you unlocked your bootloader they will still repair your device, I don't know about replacing it if it can't be repaired. But before you go that route try troubleshooting. Make sure you have the correct radio, not all roms come with the correct radio. Non-compatible kernals can become a issue to, if you flashed a custom kernal. I get the bootloop problem if I flash a rom without wiping, which I never do, except when the instructions say no wipe required, and then I get the bootloop issue. So try a full wipe, data, dalvik & cache, ext, and then reflash your rom.
I had random reboots up the wazoo. My phone was unlocked/rooted/running FRF93. I downgraded to other versions of Froyo and even went back to 2.1/CM and it was still rebooting.
Turns out that HTC actually puts it through a reasonable testing procedure to determine if it was in fact the user that damaged the phone. So even if it is unlocked/rooted and the phone passes the test, you will get your repair free of charge just like me. I'm currently waiting for them to ship my phone back.
Although I have heard horror stories from HTC, so I really think it depends on the moon cycle...
Like a poster above said, BE HONEST. Let them know the truth that it's rooted/unlocked but currently running a standard ROM. If they give you the standard "if it's rooted, you're going to have to pay", tell them that you're heard of their testing procedure to determine if it's the user's fault. Go to a supervisor if you have to.
Hi,
Thank you all for the responses... so I decided to leave the battery out completely for one day, then put the battery in the phone, and I did quickly use the phone to wipe it as well as wiped the storage clean... so the phone should be back to regular day 1 status other than boot loader being unlocked. I guess by putting the PASSIMG.zip which has EPE54B files, I forgot, and it also flashed over the ramon recovery as well.
Then I turned off the phone but connected it to the charger and let it charge completely, this morning I turned on the phone and it has been on w/o reboots.
So this points to either heat, radio (wireless, 3g) -- it does not have a sim in it currently, but the good news is that it's not rebooting. I think I'll play with wireless first, then add 3g then we'll see where it takes me, but if it comes to returning it to HTC/Google, I'll be honest of course.
This has by the way:

Any updates? I have a similar issue
Yeah I basically think it's heat related and unrelated to the firmware, RAM, etc.... I had the phone at a very cool place and it works perfectly, and when I started using it, as it got hot, it started rebooting, and I noticed the back of the phone was very hot.
So I think nxt was right #2 in this thread.
Houman
The above observation would seem to make sense. My phone would reboot while trying to watch youtube videos sometimes, but ALWAYS within a few minutes of using it on the mains...
I have since had it sent back to HTC to have the phone repaired. I had rooted my phone just to get 2.2 however as it was a genuine hardware issue they replaced the main board and now not only does the phone not reboot anymore, the issues I had with no 3G (only Edge) have disappeared too. Happy

Hi
So I got my phone back from htc, they basically fixed it and even locked the bootloader so all is well

[Q] Bought off of eBay and the camera goes black on start up.

Are there any issues with this known, is there any tests that can be performed on the hardware? When I had WM6.5 I could test various hardware pieces such as the speaker, flash or display.

This is a phone that I bought my friend for his birthday. I have a Samsung Vibrant Galaxy S.
I actually plan to sell mine and get a Nexus One. I really like the phone better then my Vibrant.
If you haven't already, do a factory reset (settings>privacy>factory reset). Since your unrooted it's unlikely it's a software fault.
Second resort, call HTC. Warranty's are device based, not owner based, so if the device is still under warranty you can get a new one
As a last resort, if your warranty is expired, I would root it without unlocking the bootloader. Try a couple different ROM's and kernals and see if you get any results.
I actually had this problem a while back. I was getting FC's every time I tried to access the camera (through any app). I figured I dropped it and broke a connection or something inside. I finally called HTC and they sent me a new one.
I had to restore everything back to stock since it was running CM6. After everything was back to stock, the camera magically started working again (and I reverted to some nandroid backups from months before and the camera still didn't work then). I returned it for a new unit anyway and HTC didn't charge me or say anything.

Rooted Nexus 6 inevitably results in bootloop

Hi all,
So iv had 2 nexus 6s so far (the first's screen cracked so I had it changed) and both have several issues, most notably,
- random infinite bootloops on restarts. Phone goes to 'android is starting' pages, and then restarts the whole bolt process again
- I have to restore phone to a backup, whereupon phone works for a bit, before
- infinite bootloops start again.
- also, Google camera refuses to work.
I have absolutely no idea why this is happening, same issue on 2 separate phones, more less. Can someone please help me shed some light on this? This very expensive piece of hardware is nothing but a table ornament at this rate.
Rooted?
You mention in the title that the phone is rooted. To be able to discount hardware errors, have you tried flashing a factory image to set it back to stock? If the same problems continue, then I suggest that you return it to Google. I did this myself when the back of my N6 started to peel and the process was painless, since they send you the new phone before you return the old one, so you lose no airtime.

Yes, as mentioned, flash a factory image to rule out any software issues. However, it is most likely hardware failure. Especially the camera fault. I've noticed this is becoming a rather common issue lately. So, you should probably RMA again.
Thanks guys. I was just concerned as I unlocked the bootloader and rooted the phone almost immediately after I got it. If I try to RMA it, they won't cry foul over a re-locked boot loader,will they?
Also,I have a feeling this might be an OTA that is acting up. It appears that loads of people have had issues after installing an ota (I did this before unlocking and rooting) so I'm going to try to flash a factory image. Thanks guys
Hello everyone,
as an update, I did exactly as dahawthorne and evolution_tech said, and re-flashed a factory image. However, i found it extremely strange that both my nexus 6s were experiencing the same issue so i did a little research.
Turns out, many users from 5.1 have been experiencing issues with changing their dpi in android 5.1 and above. Because I'm not all that familiar with build.prop and using adb shell (tried using it once, it wouldnt work properly so i just gave up), im not going to bother changing my dpi and it works all fine and good now.
To anyone else experiencing the same issue, check this page out: http://forum.xda-developers.com/nexus-6/general/dpi-conflicts-lmy47e-t3061261.
Cheers
Yep, well known issue.
