Phone Rebooted on its own - how can I find root cause? - EVO 4G General

My phone just rebooted for no apparent reason;
I am rooted with the original stocked rom.
Is there a way that I can find out what happened (without having to connect to the pc)... is there some sort of logfile that is being stored? special application to help troubleshoot?
thank you for your time

How old is your Evo?
Sent from my PC36100 using Tapatalk

Purchased 1 month after release from sprint
hardware version 003
android v 2.2
baseband 2.15.00.09.01
kernel 2.6.32.15-ge2fb08e
build number 3.29.651.5
software 3.29.651.5
PRI 1.77_003
PRL 01115

Best thing to do is wipe clean and start over. Don't download anything and use the phone as is for a day. If it still does random rebooting then its the phone.
If not then add apps once a day until it happens...

My phone only reboots randomly when I have no data service at all. Once I'm back in an area with data service it works great. I can turn off mobile data when I'm in one of those areas and it won't reboot for days. Turn it on and pretty quickly it starts rebooting again, sometimes every couple of minutes.
My girlfriends EVO does the same thing at the same time/locations, hers is a couple months old and unrooted/stock. Mine was bought on launch day and rooted/custom ROM.

Incredible doesn't detect 3G

Hey all,
I got the July 27 leaked Froyo and went ahead and rooted to 2.2.
I have noticed a pretty serious buggy issue regarding the phone not detecting a 3G network so when I'm away from my wireless router, it only shows bars, no 1X or 3G.
I have two options at this point, one of which has done me no good. Perhaps someone can help me.
Option 1: Downgrade back to Android 2.1. (More on this later)
Option 2: Try and find a way to keep this version and get back on 3G.
Lemme explain: I tried placing the PB31IMG.zip on the SD card and going through recovery to return the phone to stock. Each time I attempted this, it told me the version was old and it failed. Is there a workaround on this or do I need to find a different stock ROM?
I used unrEVOked to root the phone and have not been trying to do any frivolous additions or subtractions. I just wanna be back on my 3G. Any and all help would be HIGHLY appreciated.
Thanks!
Did you try *228 and update your PRL?
Yes. It did not help.
Always have 3G coverage where I'm at too. So more than likely phone is issue unless a tower around here is down (which I highly doubt).
Toggle Airplane Mode on, then off.
JC
Sadly, toggling airplane mode has done nothing to help either.
Upgrade to the 8/1 version...see if that helps.
JC
Try shutting the phone off, then powering back on. Or possibly that combined with an airplane mode toggle. Also make sure your mobile network is on in the settings for wireless networks. This problem was common with the first leak. I have not had it happen since switching to the second leak of 2.2.
Considering the missing apps and media in the 8/1 Leak would it be ok to do Sky Raider or should I just try the 8/1 Leak done by aiccucs?

I believe mrozzeh also gave a link to the full version of the 8/1 leak, if you are concerned about missing apps/media...
Doing that update has not helped me.
I guess I'll have to go down to 2.1 again. However, as I said, it won't load the PB31IMG.zip. It says the file is old. Any ideas?
Stupid question....you did upgrade the radio right?
Yes. Radio is the 2.x baseband.
I would be VERY finicky to update that again as I do NOT want to brick my phone.
Ok, it seems I have found a bit of the issue that is causing it. My phone number and IMSI are not detected as my current phone number. Is there a way to program this or is it an issue where I'll have to have it reprogrammed by the local Verizon rep?

try a *228 and option 1 so the phone is reprogrammed. then do a test call to your vm(*86) and make sure it connects, you should not see the 3G symbol, when you end the call, the 3G should be displayed...give it a whirl
This did not work. There has to be a way to program the phone number into the phone. Any ideas?
i've been having this same issue... messing with airplane mode and rebooting a few times got it to fix... *228 and option 2 worked sometimes. just loaded up Adryns new evo hybrid rom, working fine so far (the problem was rare, maybe twice a day tops) and did *228 1, we shall see!
To no avail on these. I think I'm going to have to see a rep tomorrow and see if we can get the phone number (my actual phone number) programmed back into the phone. I think that's a VZW thing as I'm sure they won't run me through the methods to program a phone number.
I hate that I have to go back to Big Red over this, but it is important for me to have this phone up and running. Besides internet, I have NO other form of contact.
3g issue
I had the same problem and so have many others, I flashed Skyraider Rom and problem is gone so we know its not a buggy radio, I don't think there is a fix right now, but I've never seen a Rom so stable as the new Skyraider, so you might wanna think about flashing that Rom.
Coincidence. I've heard the same with my roms, from both ends of the spectrum. Its for sure a buggy radio, and how it interacts with Froyo. Once we get a 100% Froyo ready radio, I doubt we will ever hear about the issue again.
This is the first I've heard of someone not being able to get the 3G connection back at all. Is that what you are describing? I had it not turn on, then come back after a *228/2 or power cycle - but it always came back on. Just curious but are you on an Alltel plan by chance?
Can you make calls Contra? Did you pay your phone bill?? Are you wiping all data before flashing? Try the full second leak that they added to that post. I've been using it and haven't had the 3G drop in two days now. I just took that rom and removed a handful of apps I would never use. It's working quite well.

Error Code 67 - No 3G Data - Out of the blue!

Just happened out of the blue. Had wifi on, but wasn't at home, so went to turn it of, did some facebook checking and then checked for a prl update...now no 3g data and EC67.
Looks like it forgot our sprint user name and password.
Tried doing a ##3282#, which did nothing and ##775# doesn't work.
Running Fresh 3.2 and the new htc kernel.

Tried that but of course sense 3G doesn't work, it gave me the same error faster than I could press dismiss.
I'll try again via wifi and 4g.
EDIT: Looks like that fixed it - Thanks! Haha. I can't believe that I didn't think to try it over wifi/4g, but I remember trying to update my PRL over wifi/4g and it wouldn't work, awhile back.
EDIT 2: It didn't work. Haha. The Firmware updated without giving me the error, but now the profile update is giving me a 1020 error.
EDIT 3: I think I fixed it. I remembered that I had that startup cleaner app running and that it might be killing off the handsfree updater. Looks like I'm golden now.
I had the same issue yesterday, I updated profile a few times, didn't work. Updated PRL twice, it worked. I think it was a coincidence that it worked, probably an issue at Sprint's end.
I was having this issue last night and couldnt figure out why.. my wifi tether kept stalling out and my 3g kept going in and out.
Same here, they must have done something yesterday
Welcome to hell, dude. My wife and I have been experiencing these errors for weeks now. I have tried everything in the book and nothing seems to be a permanent fix. Updating PRL and Profile is temporary at best. PRI Update to 1.40, then to 1.77 did nothing either. This bites.
Wow. When it first happened I was taking my Grandma to the store and half expected to find everybody on XDA freaking out and it had been some national/regional bug that screwed everybody's evo up - Must not have been big, but something to hit a few of us.
It's working just fine this morning after I did a ##3282# and turned up startup cleaner.
I had this same issue the last couple days. Fine today so far. Nyc area btw.

I just called them and they told me that they are having network issues in my area and there is an "open ticket." I'm sitting here thinking something is wrong with my phone until 3 other people on sprint told me they couldnt make calls.
same here nyc also did 1.7 pri update i figure thats was the problem now i am stuck with 1.34 (hours and hours took me to go back ) now i dont know what to do should i go back to 1.7 since is every one?

I updated to the 1.7 PRI last night after I got the error codes figured out. Haven't had a problem, yet, but it's been off this morning anyhow.
Never had a problem with 1.34 PRI, but last night, after installing 1.7, I did a few speedtests in bed and I constantly got 150/190 up and 550/600 down, and before I was getting either better than those, by 50% or worse than those by 50%.
This is a frequent occurrence (at least in New York City). It's annoying but don't worry about it. Anything you try to correct it will only be a temporary fix until it eventually goes away at random.
I've had Error Code 67 come up once in a while since I got my phone. Sometimes it comes in bursts, maybe 4 or 5 in a row. Super annoying. I called Sprint today and they had me update the profile a couple of times which did nothing as I kept getting the error while on the phone with them. They are sending me out a replacement Evo in the mail which I should get tomorrow. I'll report if it fixes the problem. Tech Support mentioned they do have them in stock if anyone else feels like they might be in the same boat.

I'm in NYC as well and I can't stand this error. If there was a way to supress I would be a lot more happy since if the error pops up while you are typing a number into the dialer it will clear out all the numbers after you press dismiss.
The error code is a result of Sprint working on upgrading the network to increase 3G capacity. I was getting the error messages when my PRI was 1.37, and I have gotten them a few times after updating to 1.77. At first I used to try updating my profile, but I would get the error message again. What worked for me was turning off my 4G (I'm in NYC, and there is a few test towers up), then turning on airplane mode for a minute or so, then turning it off again. For me, the 3G would kick in, and I won't have the error.
I am getting the error on 3G with 4g off or 4g since I got the phone. Sprint rep said it's not normal so Lets see what my replacement does.
looks like it hard us in NYC hard.
anyone else have horrendous battery life today after fixing this? I barely used it, I only got about 8 hours. I fully charged it when i got home, and literally watched it go down from 100% to 80% in 15 minutes..

regaining data connection

Hi guys,
I tried to do a search but didn't find anything that worked...
I've been recently losing my 3g/1x data connection a lot for long periods of time (30 min or more). It's annoying since I can't check my e-mail, or listen to Pandora, basically all the things I got this phone for since I'm limited to what I can do on my computer at work.
Anyway, is there a bizarro fix for this? I've tried rebooting the phone, airplane mode on/off, and updating my profile. I remember with my old medium intelligence phone I could tell it to check my e-mail or something and trick it into waking up the data but no such luck as the phone complacently accepts there's a connection error.
Thanks in advance!
You may want to try letting folks know if you are running stock or a custom rom, which one it is and what modem version. Whenever I run into strange issues with my phone that isn't attributed to the rom I'm running, I just ODiN back and reflash through the process and that usually takes care of most problems. G'luck.
I have noticed mine does that too occasionally. Turning 4g on and then back off usually makes 3g start working again for me.
In my case my phone sometimes has trouble finding 3g after using wifi for a while, toggling 4g almost always makes 3g work again.

Oh right! I'm just on the stock rom.
Toggling 4g and wifi doesn't work for me. Thanks for the suggestion though.
It happens more at work so it probably has something to do with that. I generally always end up roaming but I haven't had trouble in the past with using roaming data. It still says unlimited on the Sprint account website and will come back every once and a while. (I know because it'll notify me of new mail or something random.)
are you in an area of low reception? that could cause it but not sure if there is a work around for it...
this same thing happens to my wife's epic.but not regularly..
I updated the prl and seems to stopped doing it,,
I was having the same issue coming out of Airplane mode. The 3G was coming back sporadically and then not at all. I called Sprint support and they had me do a phone Restore through the service menu ##3282# (you need your MSL) and it reset the phone like it was going through the activation process. It wasn't a factory reset so I didn't have to reinstall any apps. It did work the first time but after that it started happening again.
I finally went into the Sprint store and they did a hard reset, which is the same as a factory reset (I think) Settings>Privacy>Factory Data Reset. That was a couple of days ago and I haven't had the problem since.
Unfortunately, this requires completely wiping out your installed apps. I was on the stock rom and unrooted so I hadn't backed up with Titanium Backup (needs root). But I did use AppBak to backup my list of apps so that it was easier to restore them from the Market. If anyone knows a way to backup and restore similar to Titanium, that doesn't require root, let me know.
I was having the same problem with mine and nothing worked so they gave me another one. If it's that bad call sprint tech or take it they will probably give you another one

Nexus S total network loss.

So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.
I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?
This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.
Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!
Anyone had any breakthroughs? *hopeful*
I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.
Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing
So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.
I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway
I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.

Signal drops randomly (and frequently). Verizon.

I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

Im on the newest one. Do I just extract it out of the 6.0 image file and just flash it over the top of the existing one?
I forgot to also mention that I tried getting a new SIM card from Verizon but that did not fix it either.

Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.
I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.

Damn man...I have no idea - possibly radio like the guy above my post mentioned. Wish I were of better assistance.

I've managed to get a logcat at almost the exact time the signal drop happens, I had to put it in a Zip since the Txt document was too big for the thread. The drop happened in the last couple minutes. I'm hoping someone here with more experience than me can help me solve this issue. Thanks in advance.
Having the same issue on T-Mobile smh... it gets annoying at times!

Same problem here. On Verizon
Anyone find a fix? I'm on the latest Android N Beta on Tmobile and still have the issue.
