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.

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:
Android Version: 2.2
Baseband: 32.36.00.28U_4.06.00.12_7
Kernel 2.6.32.9-27227-g3c98b0d
Build FRF91

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
Just FYI

[Q] I9000M 2.3.3 stock constant reboot and screen turned off

Hi I have a strange problem with my Samsung Galaxy S Vibrant (I9000M) running 2.3.3 stock.
Description:
a) Booting the phone would show the big S animation and bong sound however after that the animation repeats in a loop with no more sound. The phone never reaches the home screen. I notice this mostly in the morning when I wake up.
b) Usually during the morning when I wake up to check the time the screen doesn't turn on but it seems as if the phone is still working; the chime for plugging in the charger sounds. (I thought the battery was dead but it was actually at 60%)
What I've done so far:
a) I brought it back to the vendor and got a new phone.
b) Holding the power button would turn off the phone, then I would turn it back on. Sometimes it requires that I pull out the battery which results in losing all my data on the internal memory like a factory reset.
Question:
I'm highly concerned. I've gone through two of these phones and problem "b" is always a prelude to problem "a". I'd like to know if there is a possible solution and/or what the problem might be?
Note:
a) The problem started happening a day or so after I started using Samsung IM. (Skype was installed but never used)
b) The problem started the morning right after I installed Skype. (I have since uninstalled Skype, it's still happening )

You should not be losing data on your SD card by pulling the battery.
Did they give you a new phone or a refurb?
What's the build number of your phone? Should be a number under the battery in YY.MM format.

Hi Black Rose
I was talking about the internal memory not the sd card.
It's a new phone.
The build is 11.11.

If you are running stock 2.3.3 and having those issues, I think the phone is faulty.
My wife is running 2.3.3 on an 11.03 build and has no problems.
The fact that you are losing data when you pull the battery sounds like the internal memory is failing.

Alright, thanks. Do you have an idea what causes the screen to not turn on for the second phone? (This new one doesn't loose internal memory on battery pull)

I had that happen to my own phone (also an 11.03) once with Froyo 2.2 and once with 2.3.3.
With Froyo I was able to plug in the charger and the phone "woke up".
The only time it happened on 2.3.3 I received a couple of notifications at the same time and had to power it off to get the phone to work again. It never happened again in the several months I was running 2.3.3.

Okay!
Thank you Black Rose for giving me some useful information. I was just worried that this would lead to something a lot worse.
Much appreciated!

This is my 3rd phone had the exact same problem as you I heard it was something with the mother board there is a board in here dedicated to the problems with the gt-i9000m

Thanks for letting me know bambam1978; I hadn't realized there was a whole topic for all the problems. I've been searching for the specific problem where most have customs roms which is why I started this one.

Power button; touch screen unresponsive; live wallpaper still animated

Very screwy behavior on my Captivate. Hoping someone out there can help me diagnose this..
Captivate is running stock KK4; rooted via kernel swap method; some AT&T bloatware frozen in TiBu - no other image changes
The Captivate is struck on the swipe to unlock screen. I sync this phone to my company's Exchange server and have a PIN-lock policy enforced. I believe that it goes to the PIN at 15 minutes. The clock and swipe screen are showing a time less than 15 minutes after the last time I had used the phone; the screen was dark until I pressed power once, but now I can not make the screen go back to sleep. Plugging the phone into the computer does show the phone connected, and the Live Wallpaper is still running (i.e., it is not frozen in place, which I also see some times).
EDIT: After rebooting (vol-up and power does respond); it looks like something may have been up the same time as I was frozen with my phone signal - yellow instead of green; don't know if that was a coincidence or not
Any one have any ideas as to what may be going on here, and how I would remedy this?

Probably asking the obvious, but can you get into recovery or D/L mode to possibly reflash the rom?

I can, and I can reboot, and have the phone work again for the next 24-36 hours before it freezes again.
I am hoping that someone has an idea of the root cause of this issue, bad flash or otherwise, to try to solve this once and for all. To be honest, I have had horrible experiences with GB on the Captivate, but since this is my work phone, paid for, and technically owned by my employer, I have been hesitant to stray too far from stock (heck, if AT&T's tethering manager could figure out that a corporate phone plan with tethering should be allowed to tether, I would have stayed fully stock).
I'm betting that it's bad behaved software, rather than a bad flash due to the unpredictable nature of this problem, but I am not sure of a way to capture logs in a consistent basis that would allow me to trap what actually goes wrong to solve this. GB seems to get progressively less stable the more apps are installed, but I don't know if that is the root cause, or just the increasing likelihood of installing something with an insidious bug. But short of stripping everything off and losing the advantage of having a phone with apps, I don't know how to solve this and the soft reboot issue that also came with the first GB leaks and never went away.
Sigh.

There could be just one rogue app causing it

[Q] New sort of N7000 brick

At least I think this is. I have recently moved from stock to Asylum's CM10.1 but did flash a known safe kernel before any wifing occurred so I do not think this is the standard EMMC bricking.
The onset of this was gradual - phone reboobed itself a couple of times (that I noticed) but this was no huge deal for me, then a few days later the screen digitizer stopped working and I had to take the battery out - from there it degenerated fairly rapidly with more reboobs, more often returning with the digitizer not functioning and finally it is at the point where it will not boot - stuck at the loading logo.
I can reboot into recovery (CWM 6.0.3.2) but can't do a lot there - fleshing a new ROM errors out saying the package is invalid or crashes (often with a brief flickering of the screen in either case).
I can run through hg42s partition scanner - if it completes it does so without report a problem otherwise it crashes, it's about 50/50 which although it seems more reliable if mains power is connected.
If I leave the phone in CWM it will eventually reboob itself after a few minutes.
I haven't seen any magic smoke escape.
I never experienced the EMMC brick so I don't know if it was progressive as this seems to be but I get the impression it was not - and I can't rule out the same sort of problem even if the original cause is different but at the moment I am unsure about the best way to progess - I will at some point pop over to Samsung's store but ideally I'd want to get to the bottom of this with the help of the community.
So any ideas? Does this sound like a corrupt partition somewhere? Thermal sensors triggering shutdowns when they shouldn't?

interesting, try to catch the evnts in the logs, use elixer/logcat/android tuner for that.

Check the battery dude.
I had similar problesm due to bad battery.
Phone was closing itslef. And before it closesi thescreen was turning crazy
Then no boot at all....

Thanks. Did your problems occur even if the phone was on mains power? Does the battery have enough 'smart' features to affect the phone even if it is not required for powering the device?

I was outside when faced such a big problem. It was happening before like reboobs and stucks on logo. But after i took out the battery for 15 min I was able to boot the phone.
However, eventually, one day phone got stuck with a flickering screen and then it never booted. Tired nandroid restore. Did not help. Changed kernels etc. It was no good either. Then I changed battery. Did not work again Then made a factory reset. It worked. Using it without any problem now. But even at that time I was able to see my files in the phone via Qadb. This could be your case as well.
Try changing battery if it is older than 9 months. Make a full pit fresh Stock install.
Then Reboot. I hope t will work

Yup. This was indeed the problem - new battery in and after a few repeats of the same behaviour it kicked into life and has been fine since.
Thank heavens for replaceable batteries.

[Q] Power-On Lag/Freezeing

So i've been experiencing this issue for months now. I've had the issue since i've gotten the phone but its the past few months that its really gotten bad. So before anyone jumps the gun, i've done quite a bit of research on this and cannot find anything worthwhile, more on that soon.
So as usual, i'll pickup my phone and press the power button or the home button to turn on the screen, but at completely random times the screen will not come on at all. Sometimes the capacitive buttons will light up (maybe 15-20% of the time), but not always.
In my searches I found the following solutions to this problem:
Get a new sim card
Dont use an SD card
Get a new battery
Check the leads on the battery and phone for cleanliness
Factory reset
Remove 1 app at a time and test until it stops happening
Dont freeze any apps
Restore stock firmware
Dont use SetCPU
Turn off animations
Get rid of the lock screen
Remove custom message from lock screen
Clear cache through Recovery
Dont restore data with Titanium Backup when restoring apps
Turn off WiFi and/or Bluetooth and/or GPS
Dont use GreenPower or Greenify
Avoid stock launcher
I have tried all of the above except for removing 1 app at a time (and those that dont apply). I'm deep into that one and only have a few apps left to try. This is something that happens at least once a day, but typically 3-5 times in a day. I used to think i could make it happen by pressing the power button to turn on the screen and immediately hit it again to turn it off. It would sometimes work but that doesnt trigger it anymore.
My phone used to be rooted, but being on AT&T there was no "normal" way to flash a good recovery like CWM or TWRP and install roms, you have to use some other thing which i dont use. So i've always had stock recovery, im fully updated to the newest stock rom that is out, update came OTA which was after i removed root and used odin to flash an older stock rom back. My wife's Note 3 also has the same issue and it has never been rooted, we have gone through all of the above and still it continues to happen.
Also on a side note, my phone was swapped out because of an issue it had 3 months after i purchased the phone. I was able to get a brand new one, not refurbished. The issue had occured once or twice before the swap and an incredibly frustrating amount of times since then.
Reading through most of the other threads, everyone seems to have to remove their battery and re-insert it to get back into their phone. The ones that dont have to do that have found that removing their SD Card, getting a new one, sending the phone in, or one of the other options have worked. However for me, nothing has worked.
Does anyone have any other ideas? Is this common on the Note 3 (I've had it since release)? 70% of the time i can hold the power button for a few seconds to try and bring up the power menu and it works, but not always.. I usually just have to wait up to a minute or two (never actually counted, i use my phone for that stuff...which.. isnt..working...)

I've had wake lock lag on a few android phones. Even iPhones.
I would highly recommend rooting it on att and flash a mod that reduces it on the note 3. I talked about it here.

Unfortunately I cannot root my phone. I have to have my company email on my phone, and for Android devices they use Air Watch. I tried for weeks to get it working while rooted, and even used Root Cloak or something like that (with Wanam Xposed) to hide root from specific apps. Air Watch was specifically tested to work with that app but it still for some reason didn't work (new version of Air Watch perhaps with no update to Root Cloak? Just my guess). I had to remove root, factory reset and re-flash stock from Odin (that was a dual purpose flash) to remove all traces of Root so I could use Air Watch for my company email/calendar/contacts/etc again, even after unrooting and using all the cleanup tools, triangle away, and everything, it still detected my phone as rooted...
However, I don't think that's really a viable solution to the problem, that's more of a band aid. Looking at that thread and looking around, it seems to work well but I still haven't found anyone with my same issue where they used it and it worked. I would like to narrow this down to what the issue is exactly, the root cause. I think its a problem with KitKat, or at least all of 4.4.x (not sure about 4.4.4 yet).
