Unexplained Random Reboots On Froyo

I honestly cannot find the cause of this. I Have tried everything in my power to try to fix this problem but absolutely nothing seems to work. When using my phone regularly (only on froyo) my phone will get very very hot and then start a reboot loop where it keeps rebooting and rebooting and rebooting. I have the official 2.2 update. Currently not rooted but S-OFF. I wanted to see if the root was causing any problems but im still getting the reboots. I Love my Inc. and i love the AMOLED screen. I want to be able to fix this problem so i dont get stuck with a ****ty replacement. PLEEZ HELP MEEZ

first thing would be to tell everyone what ROM you're on and if you're running setCPU.

nope im running completely stock no rooting apps

I get them everyone in awhile when I recieve a text message in the background. Like if I'm in foursquare, or the internet browser for example. And recieve a text, it'll lock up and restart, sometimes it doesn't clear my uptime which is weird...

Sooooo no one can help?

I get this problem all of the time and I will tell you it has nothing to do with root. In fact, I'm not sure it is even a software issue. I have done multiple factory resets to try to troubleshoot the problem.
There is a thread at AndroidForums about it that I am currently running, but I can't link to it evidently. Look in the Support section for the Incredible.

How did you update? You're running a 2.xx radio, right?
If your problems are surviving a full wipe + RUU, the most likely culprit is that your hardware is failing.

It's a full wipe stock 2.2 and yes I have the newest radio

I was having the same issue with my phone on Stock 2.1, Stock 2.2, custom ROMs, etc. No software updates/configurations would make the random reboots stop. Anything that taxed the CPU seemed to cause my reboots. The easiest way to reproduce was to just start GPS'ing somewhere. Within minutes, the phone would go into a reboot loop that would usually only stop after a battery pull.
I took the phone into VZW while it was doing a reboot loop, showed it to them, and they put in a replacement order for me. The replacement (yes, it's a refurb) has been rock solid over a few days of heavy use. I read that if you had an AMOLED screen, then you're replacement will also be AMOLED.
tl;dr; - random reboots on stock ROM with no mods is probably a hardware failure. Go with a refurb.

Decided to go to VZW and order a replacement. They told me it would be a new phone and not a refurb but I don't trust them. Anyways it comes Thursday. I shall report back my friends. I still find this problem to be so odd

I don't got problems with listening to music, maybe some app is messing your phone. if you can't find the problem do a "Factory data reset", if this doesn't help you can bring the phone back and get a new one. It can always be a faulty phone.

My Arc sometimes reboots on me too but not randomly. It's always when it's doing something that maxes the CPU and I switch between apps simultaneously. It's quite annoying, no doubt. My old Desire never did this.
Hoping for a future fw update!

I'm on my third week with my arc and it never randomly rebooted.

It's being reported in the SE forum as well. You don't notice the reboot unless u put your phone within your view the whole day. Thats when you will notice the random reboots.

I'm pretty confident its caused by buggy software and not broken hardware.
Looking forward to flashing some custom roms and kernels to get around this and up the perfomance

15 times
my arc have randomly rebooted at least 15 times in the past 3 days. it's so annoying. what's that thing with stuffing tissue paper on the back does it work?

i've reflashed mines twice now, and done reset to factory default on top of that after the second flash for good measure, and it's still rebooting when it feels like it. i uninstalled a weather widget, and i got almost 5 hours of constant uptime. i'm about to reflash it again and not install anything, maybe just battery monitor so i can tell how many hours/minutes i can get before it reboots again.
i read about the battery fit, and i have tried various things to try and see if that was the issue, but nothing physical seems to make it reboot, and like some others, i have seen it reboot when the lcd is off and the phone isn't doing anything.
i'd really like to be able to use this arc!

mine just had the first random reboot...first I thought that the battery was all drained out but then realised after switching it back on that it was at 20%...
the phone was on idle, locked...weird!!!

Just had my first random reboot after a months use, was using google nav while charging from the cigarette lighter. Quite annoying as i was trying to find my way somewhere and suddenly realised i hadnt had any instructions for a while. The phone had gotten quite hot - i think google nav must work it pretty hard.

If you use the home button to switch between recent apps a lot (i do) then it's pretty obvious if your phone's been rebooted as the recently used apps list is empty, so i'm fairly sure this is the first time my phone's rebooted on its own.

Random reboot here, too. ^^
I was typing an email with Google Mail app (with wifi and mobile data connection turned off, actually), when the screen became all coarse and broken (does anyone remember old DOS games crashes? ^^) and then it rebootet. Everything fine afterwards except for my email, which was gone.

Screen turning on and off by itself

My daughters att gs3 screen keeps turning on and off all the time all by itself. its all pure stock, NO root, stock rom still.
Data block on her line.
She doesnt have much installed in it and i dont want to reset it. is there anything i can install that will tell me what is causing it?
I know there is a better battery stats app. Not sure if it needs root? Imunsure it will help as its a bit confusing to read thru all the readings

Strangely mines did this for a day and it killed my battery. Hasn't happened since then though. Glad I wasn't going crazy. Mines is also stock no root or anything.

This is happening on my phone too, and when the screen turns on by itself it won't time out, have to manually lock it. Thought it was something to do with smart stay but mine is disabled. I flashed a custom rom yesterday and noticed it still happening. Carriers hardware support thinks it is a hardware issue and want me to rma my phone.

I think your only option is reseting the phone to make sure the phone doesnt have hardware issues. Try a fresh stock install from odin.

Am I the only one whose GN2 locks up every once in a while?

I've been having gn2 from at&t for about 2 months. It's awesome in most respects but it sometimes locks up cold. By cold, I mean that the only way to fix it is to pull out battery for some extended time - 5-10 min. Usually it happens when I use some software, typically accessing network. Just now it happened when I used Chrome beta.
Also it happens sometimes after graceful shutdown that it locks up immediatelly on boot.
Seems to happen with any rom that I tried.
Does anyone else have similar problems? I wonder if it's hardware defect.

I was experiencing lock ups on earlier 7105 ROMs I was using. I thought power cycling was the only way then I discovered if you take out the S-pen (and then put it back) it would unfreeze the device. Maybe give that a shot next time, in case its similar.
Mine would freeze randomly...

I have never had a problem with mine, but it is still stone stock. That will be changing shortly tho...

I haven't had any lockups per se, but I've had 2 random reboots. I've had the device a week. Rooted, on stock.

I've had this phone for 5 months roughly. It has never locked on stock, Clean ROM, CM 10.1
It really shouldn't be locking up ever

Mine used to do that. Turns out the problem was Superuser. If you have Superuser, and not SuperSU, installed, try switching them and see if it clears up the lock ups.
I would also get weird notifications about "shell" and "radio" trying to get root access.

I had this problem on my SII.

My girl had this problem as well. To remedy it first I wiped the external sd card. Wiped everything off of it incase of some bs data.
Then I wiped and re flashed the rom and only restored mms and the call log with tibu. The rest of the apps she had I manually installed them one by one from the market.
Now doing the above two cleaned up a lot of lockups but it was still happening. Final thing that actually stopped the freezes was getting rid of Chrome. Why was Chrome causing issues, I have no idea but after removal the phone never randomly rebooted and after getting use to the stock browser it's been smooth sailing.

Edit: sorry just for reference both my phone and hers are running SkyNote 6 with the 6.7 update and the saber 13.4 release.

Chrome definitely may be a culprit. It happened to me often when using it. What is interesting is that it wouldn't reboot unless battery is out for few minutes. It feels like some memory state , perhaps in modem, gets corrupted and isn't cleared during boot.
And it was happening at times with freshly flashed rom with full wipe.

I have this issue too. I know for sure it is ROM or Kernel related as it never does it if I revert back to stock ROM and Kernel. Mine seems to be in a really deep sleep when it happens. I hold the power button for about 15 seconds and the phone reboots and everything is fine for a few days again.

[Q] Random Reboot

Hi,
History:
I have a problem with my Nexus. It randomly reboots. Nothing seems to help.
It started after a few months after I was rooted on CyanogenMod 10.0. In 3 days, it quickly escalated to a reboot every 10 minutes on average.
A factory reset (without user apps installed on it) on CynogenMod reduced the frequency (every hour?), but didn't eliminate it.
Unrooting to stock Jellybean 4.1.2 seemed fine only in the first week. The problem came back afterwards, and updating to JB 4.2.1 didn't help.
Now, 2 months on stock ROM, I get even more random times. Sometimes it is 2 times a day, sometimes once a week.
Just before it:
I get a metallic screeching noise for 1-2 seconds, and immediately following that, device turns off with a "pang". Although these days I HAVE had situations that the sound came for up to 3 seconds (and the screen freezes), but the phone worked normally afterwards.
What happens:
It randomly reboots. The rebooting is at irregular intervals, whatever i was doing on it (even when not using it).
What happens after:
It takes much, much longer to startup again. It can get stuck at the "Google" logo screen for up to 5min. It doesn't take this long to reboot if I shut it down myself.
Any ideas? What causes this? Is it software or hardware?
Can I even send it for warranty if I cannot reproduce the problem?
I don't want to send it to warranty if I don't have to. I don't want to loose my phone for I don't know how long.

Hi, what's your eMMC version? Maybe buggy memory, try looking at other threads.

Have you tried different batteries?

I'm new to this eMMC thing, but according to an app my eMMC Type is V3U00M. To check whether it is buggy or not it needs root, which I don't currently have. If it IS buggy, I don't have a choice but to bring it for warranty right?
No, I have not tried to changed batteries. I don't have other batteries. But can the problem really lie with the battery? Btw, my phone is less than 8 months old.

Well, I am planning to root again. I want to switch back to CyanogenMod 10.1. Lagfix app isn't needed if you can use -discard mount option right? How to use either, if let's say I'm on CyanogenMod. This is also the first time I hear of lagfix and discard mount... :/
Btw, the app i used to check my eMMC Type said that my chip is ok. No brickbug. Are you sure it's buggy?

I might be wrong here, but from what I've read at the link and other xda posts (http://forum.xda-developers.com/showthread.php?t=2029246), the V3U00M chip is not buggy (in the sense that it's stable for rooting and using the -discard command), but it does give slowdowns. I do have horrible slowdowns, so thanks for that solution I didn't know existed. However, this doesn't solve my random reboot problem at all...

No one else got any solid way to find out the source of the problem?

Same as you man...
I'm seriously considering throwing my phone to the garbage. I don't like iPhones, but google is really pushing me into it with this crappy piece of phone. Is so frustrating to have these rebooting issues, I've tried everything, from wipe to factory reset, back to stock, flash custom ROMS and KERNELS, turning location access off, uninstalling all apps/widgets that might interfere, and every single "solution" it's out there, and STILL I'M HAVING THESE DAMN REBOOTS!
Now it's even worse, I can't even transfer files to my phone anymore because, guess what... IT REBOOTS! everytime I transfer ANY KIND of file.
The only thing that seems to work for a while is reformatting and start from scratch. I've done that like 3 times already. But still after a few weeks the issue reapears... i'm really mad about this, and no one seems to care. Not Google and not even Samsung.
The only interesting thing that i found around the internet is this guy's findings
plus.google.com/113601948978986762347/posts/2ALASEC1dG2
I read the log on my phone and matches to his... but now the thing is, what do i do with this information? I'm not a programmer o something like that.
Any ideas?

I think your board is faulty. Even so, have you tried disabling SR and raising voltages across the board? Trimming eMMC? Omapflash?

He is saying that you have root you need to install trickster mod from the play store. Open the app and go to specific. Then disable the smart reflex toggles and click the oké button in the upper right corner see if that works. If it doesnt re enable smart reflex and go tot MPU voltages. Next to the words MPU voltages there is a blue plus/minus button. Click that and click the plus one time. Accept it and push again the oke button. The other two things I dont exactly know..

Honestly, if you are getting reboots on a clean stock (including stock kernel) , it's probably a hardware issue.

The thing is that after a clean stock install everything works fine for a week or two, that means no random reboots, and i can transfer any kind of file of any size with no problem. Then for some estrange reason (even with no crazy apps installed) starts with a random reboot, after that first reboot i know is time and that i wont be able to transfer files anymore, because it WILL reboot while i'm transfering files. Other thing i have noticed is that around where the camera lens is, get really hot. So I think that the reason it reboots is kernel panic caused by overheating, or the other thing is that my sdcard have some issues when writing files.
Right now i'm using CyanogenMod 10.0.0-maguro with jelly bean 4.1.2 and franco.kernel 3.0.51-nightly-512GPU and i have already tried going back to stock.
how can a I check if my hardware is fine? Is there any app out there?

512GPU? You mean your GPU is overclocked? Maybe try to set your GPU to stock. And if it gets really hot and you have random reboots you can try to over volt with trickster mod.

No, I don't think my GPU is overclocked, that's the full name of the kernel, you say that the kernel automatically puts my GPU to 512?. Anyways i just installed that kernel two days ago just because i thought it might make the reboots go away. I'm having rebooting problems since february (just after upgrading to 4.2.1), so i don't think that the GPU is causing the reboots.
