Random reboots - Samsung Epic 4G Touch

Not good right my evo did this but when a custom rom was used.
It would reboot at random times and gets annoying. Is this cause for a sprint store visit?
Samsung Galaxy S Dos indeed

i love the community here

It's a known issue, regardless of stock or rooted. The more people that report it to sprint/samsung, the faster it gets fixed.

random reboots are a common thing?
I will have it checked out by sprint tomorrow but it will be a lottery if I get one with LOS

Random Reboots...

Hey everyone, I looked around and didn't find anyone having my particular problem, but If I put this in the wrong place, or someone has already solved it, just let me know. Don't want to waste your time!
I got my DINC the day they came out in stores...the first one my local store sold in fact. It was working great, but I hated the bloatware and the fact that the Bluetooth stack was not up to date...couldn't connect with a new hands free speaker phone I just bought (Parrot mini-kit slim). I had occasional random reboots, but not too many. Once or twice a week maybe.
So when the unrevoked one-click came out I tried it. Worked great.
Then I started trying ROMs. With everything I've tried I get random reboots...a lot of them. Sometimes it reboots once and works fine for a couple hours. Other times, it will loop until I do a battery pull. When it loops it will sometimes make it all the way to the lock screen, sometimes it will only make it to the boot animation, and sometimes it won't get past the white HTC screen.
I've used a couple different nightly builds of CM6, with and without google apps. I've used Skyraider 1.8 and 1.9 with and without sense. I've tried "touch of photons". Same results and activity on all of them.
Last night I gave up and downgraded to unrooted 2.1 with sense...factory fresh. I reformatted my SD card with the phone, reformatted the phone storage, and I've done factory resets. It still isn't working right.
At this point, I'd be happy to get it back to pre-Unrevoked and just wait for the official OTA Froyo which is supposed to come out soon. Rooting and using a stable rom is fine with me too. I just need a phone that works consistently.
Any ideas? I'm pretty desperate.
sounds like you needed to return it and get a new one since it was doing random reboots from the day you bought it.
have you used any of the hydra kernels to try and OC it, the 1.15 OC would cause mine to reboot. a good stable rom that i tried was JagerRom, 1.7.4 is without sense, and chocolate is with sense. don't try the OTA one because that is for people who updated to the OTA leak and im going to assume you aren't one of thoes people. haha

hope this helps
Thanks Stroupified...
The weird thing is that the reboot issue wasn't that big of a deal before I rooted and started flashing roms. It happened, but not enough to be a problem.
Does the camera and camcorder work on Jager?
Does anyone know if there is something that could have gotten messed up with unrevoked or the roms I tried?
Is there another downgrade method I can use? I just installed the PB31IMG.zip you can find in a few places out there...is there a known reliable source for the downgrade zip?
If I can avoid fighting with Verizon on this I'd like to. I'm obviously outside my 30 days, and I don't want to wait a week or 2 or three or more for a new incredible (if I can convince them to get me one). I'm not even sure warranty or Asurion will do anything with this kind of a problem either...I fear I'm stuck with a $500 reboot roulette machine.
re
i have gone through 4 incredibles.
they all exhibited the same rebooting issues... completely stock with NO installed apps.
I have also tested the phones with 2 different batteries and with different sd cards and no sd cards installed.
I had done factory resets.
I get a ****ty cell connection where i live, -100 to -96 db.
Its looking more like a tower issue..
I also have had a reboot issue. I rooted the phone the day I got it and installed a senseless rom. It worked perfect the 1st day then started into a downward spiral of reboots till it went into a full boot loop. I did a nandroid back up of the original rom. No real issues since. Im still rooted and have only had one random reboot in about a week that I know of. I know the first issue was because of the rom but what causes the random reboots. Is it aloss of signal? Im a noob so Im just trying to get some insight.
Im on #2
I got my 2nd Incredible on Friday. Prior one would just get hotter and hotter (possibly due to signal issues) until it would enter a reboot loop. Hoping # 2 fares better.

ya everything works in jager. but from what everyone else is saying it seems like it could be the signal (or lack there of) that's causing the reboots. have you tried the hybrid prl? it uses the verizon and altell towers instead of just the verizon ones. i haven't tried it because im in cali and there aren't any altell towers near me, but if your stuck with the phone you might as well give it a shot if you live in the supported areas. good luck man.
Link to PRL thread:
http://forum.xda-developers.com/showthread.php?t=723829
If you don't have problems with signal don't bother with the hybrid prl... it kills your data speeds because it switches you from Verizon data network to Sprints data in most areas. I know in the Carolinas phones randomly reboot a lot because thats Alltel country and phones don't work properly without the hybrid. But down south its mostly Verizon. Out west Texas/Ok is mostly Alltel.
But man honestly - I have the same issue on custom roms. My stock Sense rom does fine though. Sometimes I'll be on a custom rom typing a text and the keyboard just freezes and its over. lol nandroid time to me - I can't take the reboots but hate not having the features of newer software.
re
i have tried the hybrid prl and it did not help my rebooting issues.
i have also tried switching to the the cdma codec to -b the higher quality compression... with no luck in fixing the reboots.
I have also made sure there was not an issue with an app causing it, i have tested mine with a clean / factory reset with absolutely no apps installed.
I have had 100% good luck with the leaked ota update, the one upped the camera to 720p recording as well as a hand full of other fixes, and not once did my incredible reboot or crash.
I'm pretty confident that htc has fixed this issue for me, once they drop the 2.2 update that everybody seems to be speculating will be released in a handful of weeks.
Thanks for the input everyone, and I'm sorry others are having the same problem.
I went by my local Verizon store (actual Verizon store, not a 3rd part dealer) and told them my phone was rebooting repeatedly. They didn't even touch my phone...I was out of there in 5 minutes with a FedEx 2nd Day Air confirmation number for a new handset. And my wallet is intact also. I'm rarely impressed by Verizon's customer service, but this time...man... Between the new handset and the impending 2.2 update, I hope to be in good shape.

Same EXACT thing happened with me and telesales. No scripts, no hard reset, no task killer; NOTHING. Said "my phone gets hot and reboots" and they said (last Thurs), let's get you a replacement overnight so you can try the new one out of the weekend. No muss, no fuss. Got here 10:30AM the next day, and my evil super-heating 4-to-13-reboot-try prone phone is going back.

I don't believe towers/signal would have any effect on shutting down or booting. Basically once you're on a current PRL, you really shouldn't even have to update it. Unless you're having that poor service deal where an Alltell/Vzw hybrid would benefit you.

POLL: Have you ever had reboot problems?

Have you ever had intermittent reboot problems on your Incredible?
Did you do a warranty exchange or were you able to fix the problem?
This is regardless of what ROM you use, it could even happen when completely stock. If it is happening when completely stock and/or you were never able to fix the issue, it is most likely a hardware defect (failing/overheating 3G radio?). I'd like to see the prevalence of this problem and if it pertains to one version of the Incredible in particular.
I hesitate to vote "never", because CM was initially pretty shaky, but you asked regardless of ROM. The stock ROM was fine for me, and CM has been great since the RIL update.
Yes
Random reboots on multiple ROMs. Haven't been back to stock because from what I've read, the problem won't go away.
Unlike many others I've read about, my reboots are completely random and are just as likely to happen while idle as while doing heavy processing.

Yeah if yours was fixed after the RIL update and if the stock ROM was fine, you're definitely not having the hardware problem. In your case, it is just from CM.
Yes and No
My first DINC went back due to reboots which were based on overheating which was, in turn, based on a bad hardware radio (present in many first batch DINC's).
My current DINC has rebooted only a small handful of times, and always when the signal is super poor.
So my 2 cents is ... check you temperature ... if its high and you reboot RMA; if its low and you reboot, check your signal.
That must be what happened to me too. I pre-ordered the DINC and had an early AMOLED version obviously. I do agree that it was because of an overheating/faulty 3G radio, that's the best explanation I've come to so far.
My first Incredible was great for the first 6 months but then it got a spot on the screen that wouldn't register touch inputs anymore so I got a replacement. The replacement from the day one has had rebooting issues. It's happens when I use 3G. I think the phone is overheating and reboots. It doesn't happen very often when I'm on wifi though. The replacement was stock ROM.

I would get a replacement for that one as well. It is most likely the 3G overheating issue.
Here's my story:
I had an original AMOLED version back when they first came out, it was rock solid until whenever I made this thread. This was after rooting, custom ROMs, etc. The phone would reboot whenever it wanted to.
I asked for a replacement, and they gave me a refurbished AMOLED. This one was even worse, as soon as I took it out of the box (completely stock) it would start rebooting when I tried to turn it on.
Finally, I got another replacement, and so far I have been happy with it.
Of course, all 3 were AMOLED versions, they always give you a replacement of the version that you already own.
I had this problem for two months ... I tried everything. I changed ROMs, I changed kernels, i changed batteries, i *228, I performed a ruu... nothing worked.
I went from a 1 to 4 reboots a day to now none! I have no idea why. It actually stopped when I started using Athena but I think its just coincidence.
I've been reboot free a month.

The reboots seem to be pretty random even when using completely stock incredibles. Without even a history of rooting it is possible to have a reboot issue. The problem is the phone/hardware itself and not user error.

Anyone Still Have Their Phone Unrooted / LOS Bug?

So I would like to know if anyone out there besides me has not rooted their phone yet and if not, have you gotten the LOS bug?
I had purchased an E4GT when it came out and ran it stock for about a week. Did not have on LOS. Then decided to root it and within 12 hours I had an LOS. Within another 12 hours I got another one. Nothing in my use had changed and it happened in my house both times so it was not like I was in another situation that I have not been in.
I exhanged the phone for another one and obviously did not root it this time around. It has been over a month now and I have yet to get an LOS. I have traveled in areas where there is no Sprint service, through farmlands, etc. My phone roams fine. I have been on 3G, 4G, wifi, and an airave and there is nothing that will give my phone an LOS.
I also have a friend who owns the phone and I refuse to root his because he also never got an LOS since release day and I would be willing to bet if I rooted it one would show up not long after.
This is not to bring out the haters but I want to hear from people who have never rooted their phone. Not the ones who rooted then re-installed stock. I am sure we will also get some liars in here but I usually can pick out the trolls.
This is for true LOS, not that your internet connection wasn't working or your calls went straight to VM. I have had things like that happen for years already on all of my past phones.
Never rooted, never had LOS. Damn do I miss wifi tether.
You have been Epicly Touched by Jesse Buck
Yes I'm not rooted and I have gotten LOS. Not as of late (for over the last week) but I've had 4 total the 4th one I really can't blame the phone or Sprint since everyone at the time that was/is on sprint was having the issue (20+ people I go to school with)
Outside of that I've not had an issue as of late but yes I've never been rooted and I've had LOS as have other people in this forum as well.
I do not have LOS with Chris41g's kernel.
My brother who is completely stock/never rooted gets LOS from time to time.
Never rooted, and no LoS for me.

Couple of weeks. I find the newer versions are better than the old.
I haven't rooted yet and I haven't had a single LOS since I got the phone on release day. That's the only reason why I haven't rooted, I'm afraid that if I do then I will start getting LOS. I wish there was a root method that didn't involve flashing anything, then I would pull the trigger on it. But for now, tethering and adfree are not a compelling enough reason for me to root and deal with the risk of LOS. I see no reason to flash a custom ROM or kernel on this phone seeing as though it is fast as hell and butter smooth the way it is. I would like to delete some crap from it though.

Totolly Agree and feel exaclty the same way. Although, even with the crap on it their really is no negative effect on the phone at all.
I am willing to say that almost everyone that has rooted their phone has seen an LOS where the ones that never did will most likely never see one.
Everyone is *****ing about Samsung that really is more of a rooting issue and not a manufacturing issue. I hope this gets sorted out and whatever Samsung updates will fix the issue with root. I can hold off for now but once an ICS Rom hits, it is going to be much harder!
Had this phone since launch and haven't rooted yet. No LOS at all. Phone goes on roaming and out just fine. First phone I have had stock but this phone is a beast. Will root once the LOS is solved or there is a rom that I can't wait for.

I got the phone on launch day, LOS (stock) started on day 3. Rooting didnt help. Took it back for a replacement and havent had LOS at all... I rooted/added CWM yesterday, no issues. BUT, I havent flashed a rom yet, and I wont until this "update" is out...
I was stock until 2 weeks ago, and I've had the phone since one week after it came out. On stock, I had LOS 1 time. After I rooted just two weeks ago, I've had it 2 or 3 times.

If it were a rooting issue and not a manufacturing issue, then why is the manufacturer admitting that it's a manufacturing issue and releasing an update to fix the manufacturing issue? If it were a rooting issue, they'd have said "don't root and you won't have the problem".
I didn't root at first for fear of LOS, then I got it twice on the 4th day after release so I rooted anyway. Got it 1-2 times a day for a few weeks. Started running chris41g's lostkernel and now I get it once every two days to once a day tops.
Can't wait for Samsung to fix their stock problem at least they're on it this time and not screwing us like the epic 4g...which just got gingerbread i heard.
Not rooted, have had the phone since the week it launched - experienced LOS ONCE while in my house on the couch where I use the phone a lot. Haven't seen it since. I really, really miss being rooted mainly due to wifi tether and hiding annoying ads but I think the biggest thing right now is the effing camera click sounds.
I really wish there was a simple, straightforward root process that just "unlocked" the phone without really changing anything. Is such a thing even in process? Until then, I'm likely not going to do jack because LOS problems would be a ***** compared to the annoying camera clicks.

Flashing may trigger LOS, but it is not the root cause (no pun intended). My phone is bone stock and had LOS bug pretty bad. Even happened in a Sprint store while I was showing them.
CS had me do a data profile clear/re-update and all has been good since.
If you think rooting is the cause of LOS you're wrong, plain and simple. Some kernels may cause it to happen more often however. I had it 4 or 5 times when stock. I'm rooted now with chris41g's stock pulled w/cwm5 kernel and haven't had LOS since. I won't be surprised if I get LOS again, but it's definitely not because I rooted my phone. It's a problem right out of the box
Once again, root (su binaries and busy box, typically) DOES NOT CAUSE LOS.
The phones can get LOS bone stock. Mine did.
Custom kernels seem to exacerbate the problem...though new kernels seem to have figured it out. (current kernel is over a week in use with no LOS...as good as stock)
You can have root with a stock kernel.
You can debate LOS occurrence frequency differences between stock and custom kernels but please get your terminology straightened out. All of this is causing the conversation to always turn into a debate into an argument, every time and scaring people who want to root...and them the conversation comes back, the cycle persists and just gets louder every time.
Get your terminology straight...
...root has nothing to do with this. Period.

Thank you - that is what I was wondering. I understand what you're saying about rooting not being the cause of LOS but, as you said yourself, some of the kernels used to root these phones seem to exacerbate the problem. There are a few different camps of thinking here and one of them is the group that almost never or never experienced LOS out of the box. To them, the link between rooting and seemingly more frequent occurrences of LOS is enough to make them hesitate to root. Another group are those that experienced LOS already and maybe have nothing to lose to rooting and seeing what happens. I can tell you that, having experienced only one LOS since launch on a stock GS2, if I were to root today and experience LOS tomorrow I'd just have to link the two.
I'm not very knowledgeable on the rooting process but I have rooted almost every android phone I've ever had: Hero, EVO, Photon. ... I'll have to read up on which of the latest root methods for this phone seem to be the best as far as not experiencing LOS and maybe I'll just give it a whirl and see. If nothing else, it'll add to the body of knowledge and experience for this phone.
I'm a month into ownership and still no LOS. Been rooted on and off for 3 weeks and have run both types of LoStKernel and the Stock Pulled Kernel. I've flashed back to completely stock unrooted twice to have a clean slate to work with. No issues yet.

Menu key menu pops up during low signal

I have an extremely annoying issue. I've seen some posts reporting this on various boards, but it seems most people throw a default answer out there that it's a hardware issue. I'll explain why I don't think that's the case.
The menu that comes up with you press the "menu" capacitive key has been popping up and down rapidly and repeatedly when I'm in a low signal area. This didn't start happening until after Samsung/Sprint fixed the LOS issue. I'm thinking it has something to do with the way they fixed it, which I don't have any technical or general knowledge of. Most of the time, the screen and keys will not be responsive unless I hit the power key to turn the screen off and turn it back on. It's even more annoying since it vibrates everytime the key is "pressed". I don't think this is simply a hardware issue as the only time this presents itself is the same times the LOS issue used to. I'm sure it's tied to that fix somehow.
Is anybody else having this issue? This may be a long shot, but I installed the LOS Checker zip, (I forgot which dev created it), and never uninstalled it, but I've upgraded many roms since then and don't think it would still be installed.
If any of you do have this issue, did you ever install that LOS Checker zip?
Rom= Blazer Rom EL29 v3.8
Kernel = rogue 1.4.1
Started happening to me recently as well. Im running Calks still on GB with ICS theme. I haven't paid attention to my signal when it happens but you are right, turning off the screen does stop it momentarily. I agree this may not be a hardware issue as well. I've just been bearing it because I plan on changing phones soon anyway.
Edit: It just started happening after this post. Signal was at 1 bar...

I have this same issue. I never realized it correlated with low signal. The issue cropped up 3 times today and each occurrence was with low signal. Good eye sir.
Do any of you undervolt or use a kernel that runs less than standard voltages?
My device is undervolted quite a bit and was wondering if it may be part of issue as i don't remember having this problem prior to that.
I am removing my undervolts and will report back if i still have this issue.

I think its a hardware issue. Im running the same setup on my replacement phone and haven't had the issue since.
I experienced this ever since I got the phone back in september but I didn't wise up until the 14 day period ended. there are two threads in the Q&A section concerning this, one that i started and another that i contributed to.
I would be trying to text and the menu button would pop up and i would accidently hit something on the menu that came up bc the button spazzes out randomly and consecutively and sometimes for a solid 5 seconds, but like the rest of you im sure, it wasnt confined to any single app so it was impossible to find one thing to blame. it would have to be something system-related or hardware-related (btw i did flash the LOS checker some time ago)
I believed the low signal theory for a while, as well as having a corrupted flash. but I experienced the spasms with full bars of service AND after a complete Odin restore to stock everything without restoring any of my past data whatsoever. thus I deferred to the "default" that it is hardware-related.
that was months ago.
I got so fed up with it, i decided to do anything to make it stop. So, I recently opened up my device and took everything apart and found that the water indicator just above the capacitive buttons had been activated. keep in mind I DID NOT EVER have any encounter with water. in fact, the other water indicators were perfectly undisturbed. this pissed me off because that means there might have been an accident or something while they were being manufactured that would have damaged the button - idk just another theory.
This is my main piece of evidence supporting my claim that it is hardware-related:
I ended up breaking the screen trying to separate the glass from the digitizer (stupid, I know bc theyre fused together) so I ended up buying a new screen/digitizer. put it in myself. i haven't had it since. I'm running the EXACT same set up as before I replaced my screen and its been about a week and no instances. I would be experiencing the sporadic menu button randomly, several times a day but it has completely disappeared.
i suggest to you all: bring it in to Sprint if you bought it from them or invest in a new screen off ebay if you bought it from a 3rd party seller (Amazon, wirefly, letstalk), i got my new screen for $65 shipped and it was in pristine condition. now im living a happily-ever-after ending
i'll keep a close eye on this thread to help you all with your endeavors/theories though
if any of you plan on opening up ur device, i suggest you do some homework so as not to destory your phone - its still an amazing device. or you can just ask in this thread and i can give tips to everyone
good luck!!
Thanks for all the updates.. I've noticed I'll sometimes get this error, but my phone will be showing full bars where I KNOW I have a poor signal.. for instance, my elevator at work..
Is there any sort of logging app I could run and go into an area I know this will happen to find out what's going on?

sometimes the signal bars are inaccurate (like you described). your true signal is found in settings>about phone>status>signal strength. 0-1 bars is really about -90 to -100 dBm
devs use logcats to analyze issues with the internals
http://forum.samdroid.net/f38/tutorial-how-get-logcat-example-check-battery-drain-2543/
I just checked a few other boards and it seems a number of people have confirmed it correlates wih low signal. There are a few people that keep popping up on multiple threads stating it's a hardware issue, only because a new screen fixed it. I would be fine with that logic if there weren't so many people stating it correlates with low signal. Also, it seems most people haven't really experienced this issue until after the LOS fix. Now, at the same times I used to have LOS issues, I now have this. I'm guessing it has something to do with internals and whatever they did to update it may be separate from modems or roms, since people have gone back to stock and still experienced this issue.
I haven't done a search, but is there an information source that states exactly what Samsung did to address the LOS issue?
I'm going to ODIN back to the original shipped EG30 package and test it out.. I never did OTA updates.. always through ODIN, etc. I'm going to see if I update through OTAs if anything is different. I'll report back.
I had experienced it since around the 1st week of october. i didnt have los fixed until i flashed chris41g's experimental kernels, not sure when all that was though. i was convinced it was related to signal too, but i would still happen on the highway/in public with 3 bars of 4g and ~50-60 dBm
would be interesting if you figure it out though
Yea I ODIN'd back to EG30 and now OTA'd to EL29.. no issues yet but we'll see tomorrow when I'm in elevators. After doing all this, I realized I probably need to do a full EEPROM reset and then go through this... don't really feel like doing that tonight though.
Im pretty sure this is in fact a samsung phone issue in general. I came over to sprint and the e4gt from verizon and the fascinate. I loved that phone, but it had this exact same issue. I have not in fact had it happen to me so far with the e4gt yet. I have a sneaking suspiscion that this issue goes hand in hand with undervolting, but thats just my own personaly theory.

Happens to me on the rare occasion as well. Might be an issue with the phone?
I called this one during the LOS era. It definitely occurs in low signal areas. I could never get LOS so I went into known dead spots and sure enough those random pop ups happened

I noticed there were a few other threads on Samsung devices with issues.... hmmm. Did you ever try limiting your underclocking to a higher clock speed? This may be a noob question but for the EG4T, is anything less than 800mhz considered underclocking?

I believe I remember seeing your post haha... I'll see what I can do if I mess around with clock speed.

[Q] Occasional complete signal loss

My wife and I each bought our Nexus phones a couple of months ago from the Play store and signed up for Straight Talk. Overall everything has been great (except of course my wife cracking her screen, but that is another issue). A strange signal issue has happened to each of us a few times. Most of the time everything is fine. However we've both had the situation where the phone completely loses signal and it won't come back on its own. For me, it seems to happen when I am in an area with very poor to no signal. It's like the phone stops trying to get a signal completely. The signal meter shows the empty triangle and the lock screen says "Emergency Calls Only". Even when I get back to a strong signal area it doesn't pick anything up. My wife had no signal for a couple of days since she was on Wifi and didn't notice the lack of calls/texts. Rebooting the phone fixes it and switching the phone to airplane mode and back also fixes it. I am almost always in area with decent to good signal coverage so this doesn't happen too often.
Does anyone else experience this? I'm wondering if this is a Nexus or a Straight Talk issue?
EDIT: I didn't mention before, but I am running both phones stock and never been rooted. So this is definitely not a custom rom issue.
I have had the exact same issue with my nexus, same solutions as soon as I leave the poor signal areas(airplane cycle, reboot) . I am, however with at&t (just using my old s2's sim) and my wife has experienced the same issues with her s3. Leads me to believe that it is a signal issue. My two cents for the same experience, carrier or not.
I777 gets it done, gnex just for fun
I've been getting this issue for the past few days. I'm on T-Mobile. This never happened before and I don't think it's a rom/kernel issue as I've tried a few roms and was experiencing the same issue on all of them.

Actually, I probably should have mentioned it, but neither of the phones are rooted. Just stock all around.
I got a similar issue from not flashing JB radios along with CM10, but........

Both my nexus, and the wife's s3 are also unrooted, as well. Jb simply hasn't given me a reason to root, I'm not displeased with anything. My issue with signal stopped yesterday, and I confirmed it wasn't a phone issue for myself by popping my sim back in my rooted s2. Still had zero service. Hopefully your issues will also resolve themselves, if they haven't already

My little brother had this same problem on all roms, though he had a cdma version, i don't believe this is a mere coincidence, we were able to replace his since it was within the thirty days. But i think this is a "needle in a haystack" hardware issue, and you're just the unlucky ones. Though I could be wrong, many people have had this issue before as I've searched on Google to try to fix my brother's phone.

I have same problem with both Galaxy Nexus and my previous phone, the Nexus S, only thing I have to do is reboot, after reboot, problem is gone, but it could come back in time, but I recently update radio, and haven't seen this problem quite while.
One other problem is, sometimes when i enable the airplane mode, was unable to disable it unless I reboot it...
