[Q] Random Reboots

I'm curious if others are seeing their EVO reboot with random use. It doesn't seem to be related to one specific application although it is hard to say if a background app is the cause. I will be using navigation or an Internet-based app, then the screen goes black and the phone reboots.
I originally thought it was due to rooting, but I'm seeing it on different ROMs. I've wiped the cache and data when flashing the new ROMs and I've tried running with limited apps loaded with my recent move to the OMJ ROM. Everything actually runs great with the exception of the reboots.
I'm posting the issue here since it doesn't seem to be ROM specific and I'm curious if it may be hardware related. Is there a tool that would allow me to easily catch a log of the potential error to seek further help? A point in the right direction would be greatly appreciated.

I'm running stock 2.2 no root, and with gps on my phone reboots in the middle of 911 calls. (Thank God I wasn't calling about an immediate emergency) but it happened twice, once when I called and the other when they called me back. After turning off GPS, it worked fine. I thought this was a bug in 2.1 before update1, I didn't receive the problem until the 2.2 update.
adb logcat might see an error, but I'm not really sure.

Seeing it here. Not Rom or application specific.

try a factory reset.

That's scary news about the reboots during 911 calls. I can't say that I tested that as a trigger for the reboot and I hope I don't have to in the near future. However, it makes me curious if it is related to the phone's interaction with the Sprint network. In your case your 911 call may have been a direct trigger whereas my reboots are seem indirect while I'm using my data plan.
One reason for my reboot was due to me getting the Error Code 67 "Your PCS Vision username and/or password may be incorrect" when trying to tether (USB or hotspot). Rooting allowed me to tether using 3rd party apps, but there may be the underlying problem with my account.
I also should have mentioned that the reboots happen with GPS on as well as off. I typically have it off to save battery life. I've also done factory resets each time I've changed or updated my ROM.
Thanks for the feedback and suggestions so far. I'll try logcat and continue to monitor the forum for advice. I'll also post back any answers I may find elsewhere.
Thanks again.

I had a reboot tonite, phone was just sitting on table off charger about 90% battery, and I heard the Sprint screen come on looked down and noticed phone was booting up....no idea why first time I've noticed this.
Stock froyo no root...unfortunately :'(

Correction... I meant to say that the reason I rooted (not rebooted) was to get tethering without running into the Error Code 67. I tried the various solutions posted for the Error Code 67, but nothing seemed to work. But I'm curious if this may be part of the underlying issue if my device reboots based on a faulty account configuration when using some aspect of the Sprint network.

The exact same thing happened to me last night. I sent a text, switched to my GMail and then boom. Error message about failure to send an SMS then reboot. Stock unrooted FroYo.

I had reboots only when using Undervolted kernels.
Seemed to be triggered by GPS + Phone call.

Yes, I was also having this problem. Definitely GPS related. Usually it would happen only if I was using the GPS for a long amount of time (navigating) - so I imagine it may be conflicting with cellular data if I received a txt while navigating or something. Who knows.
It was driving me crazy because A. I got lost and B. It started rebooting constantly and would randomly get caught in a boot-loop. I even had the problem after wiping EVERYTHING (even my SD) and reinstalling various ROMs (I tried 5 different ones).
The only solution I found in the end was to find the latest radio and wimax updates, wipe, re-install those - and then install the ROM again.

GPS may be a symptom, but not a cause for me since I typically have GPS off. I find that it typically happens when I'm using a networked based app, like the web browser. Following your post I turned on the GPS, started the navigation app and found that my EVO rebooted after the same amount of time I was experiencing with GPS off.
The more I think about it, it does feel like I just assume that it will reboot after a certain amount of time passes (regardless of app). GPS and Internet are two uses where I will have the screen on for more than just checking email and etc.
Your reply gave me hope and I wiped, reset and reinstalled today. All seemed well and then... auto-reboot. This is driving me nuts. I'm seriously considering reverting back to stock to see if that stops it.

Don't go back to stock. I did and it did not fix the rebooting problem. Now I have the rebooting problem and don't have root anymore. Out of the frying can and into the fire.

What's funny is that my phone went through a few days where it would randomly reboot, and this was before I rooted. When it rebooted for the second time in a meeting, I pulled the battery, and didn't put it back in until the meeting was over a few hours later. Don't know if that did anything, but it hasn't rebooted on its own since.

Having same issue and my theory is that its sd card related in my case at least... I think it might have to do with froyo netarchy based kernals found in most of the newer froyo roms combined with a slow sd card. (on hardware rev 2)... try flashing a 2.1 rom like fresh 1 or one of the 2.2 roms with an htc based kernal like the am evolution or cyanogen with snap5 or 7.11 (onyl 7based kernal ive tried so far, was panicking because i thought my evo was wrecked). those have both worked for me and i had that issue with 1.3 baked snack, fresh 3, evio and damage control. got random reboots when phone is totally idle, in use, charging or not. evio runs super smooth but the restarts...)
edit for spelling and update roms that gave me the reboot issue.

+1 for random reboots here... it is CERTAINLY more prevalent during GPS use, but I've gotten it without.
Fresh 3 + King BFS#4 got me in a bootloop requiring wipe reflash, standard baked snack 1.5+whatever kernel it comes with has been doing it.
I dig the battery life I was getting... but if undervolting is causing this... ugh.

I'm also getting the boot loop problem. Stock 2.2, all updates.
I've even done the hard reset.. twice!
I tried to follow it with LogCat, but reboot disconnects adb. I was thinking it was the SprintZone app. The P.O.S. app is doing all sorts of non-sense while booting, but eventually it'll reboot around the 11th time and freeze at the "htc EVO 4G" screen.

I wish we could get some resolve here D;

Random Reboots
Thanks for all the input and I'm sorry to hear that I'm not alone, but it is a bit comforting to know I'm not the only one that is frustrated.
I took gleax's advice and I dropped down to the stock 2.1 release found in the thread number 715915. (Sorry, the forum won't let me paste the link.)
I did the required wipes prior to installing the new ROM and I'm still seeing reboots. I now see the OTA update for Android 2.2 and I'm tempted to accept, then send the phone back to Sprint in the even this is a hardware issue. I'd prefer not to, but there doesn't seem to be a way to identify the issue and work towards a resolution. I've tried logcat, but the log seems to start clean after each reboot. That being the case, I don't know how to capture the log leading up to the reboot that would help identify the issue. Any suggestions on a logging tool and where to post to help several of us that are seeing this issue?
Gleax suggested this is may be SD related, so I bought a class 4 card in addition to dropping down to 2.1. I'll give that a shot and try another clean 2.1 install. I'll post the results here in the event they may help others. I'll likely give it a week before unrooting and seeking help from Sprint. I really need a usable device more than I need root access (although both would be ideal).

I had this problem on a very regular basis when I was running OTA 1.32, 2.1 android.. but since I rooted and went to SteelH's stock 2.2, no issues at all. Updated radios when I did that as well.

Hrm, I may have to try flashing to a stock build for awhile... it'll KILL me, but even fully wiping, new radios, cyanogen, still get crazy reboots.

Help- limited 3g data

I have been modifying my phone since the the beginning of the Inc and have a lot of modifying/ flashing knowledge, however this one stumps me. I have never had any data/ 3g issues with this phone. Just the other day I was pulling 2.4 mbps speed tests and having very fast data. Today at work I noticed that web pages were acting very slow and so was the other data on the phone. I tried all of the usual things (Toggling airplane, restart, *228 option one and two), and I still cannot get my data working properly again. If I toggle the airplane, as soon as the 3g sign comes back in white it is very snappy, however seconds after that once it turns green it is so slow and most of the time doesn't finish loading. I tried calling verizon to see if there is any outages in the area, and they said that everything should be fine.
Since then, I tried a full wipe (reset, cache, and dalvik), and installed the newest version of CM7 nightly 201. This didn't help the problem and I am still having the same issue.
I looked into a RUU reset and Im thinking that might be my last option. Would I loose root doing this and could it easily be retained with unrevoked? Also should I use the froyo RUU or can I just go with the newest GB?
Any other suggestions on what to try?

Do the 2.2 RUU, as you can root again with Unrevoked. If you use the 2.3 RUU, you need to be s-off or you cannot root.
I'd do the 2.2 RUU.

BEFORE the RUU, have you flashed any Sense 3.0 rom? If you have noticed instances where 3G drops or you seem to be stuck in 1X you could follow this thread:
http://forum.xda-developers.com/showthread.php?t=1229732
In regards to the rom mentioned in the thread, you could also use JoelZ9614's OTA rom or Incubus26jc OTA 2.3.4 rom from what I understand.

Verizon's "data slow down for the top 5% of data users" has recently been put into effect (even though we heard about it months ago).
If you use a lot of data you probably fall under that category and it's why you're limited.
No way around it since Verizon caps it through their network.
If you're limited it's likely that it's not even possible for you to get in the top 5% next month and your speed will be returned.
// Just one possibility. May be your ROM, Radio, PRL, high traffic, tower issues.

[Q] Problems after 2.3.6 update

I got the update pushed to my phone yesterday and ever since there has been nothing but problems! First, the battery drains at a ridiculous rate. I unplugged it at 10:30 am and by 3:00 pm I was down to 60% without anything going on except 7 text messages. I can usually go 24 between charges. Second, the overall speed of the phone has slowed to a crawl. Web pages take forever to load, the app marked just hangs on the loading screen, and apps even take minuets just to open. Third, my phone randomly loses data connection. I cannot load any apps that require a data connection even when the wifi and 3G logo are showing with full bars. I get an error massage that says "connection failed" or "retry." it's so bad that when trying to sync notes or email my phone has the scroll wheel of death and freezes on that page. I've had the phone since thanksgiving and haven't done anything to it, its completely stock, I don't even know how to jailbreak it! I haven't had any issues whatsoever before I updated and now my phone is pretty much unusable. Is anyone else experiencing this? I need there to be an update to fix this update or for someone to tell me how to downgrade back to 2.3.4

You should try rooting and running an custom rom or kernel. I've received the ota as well but i immediately rooted afterwards. Im running the stock rom but using a custom, overclockable kernel, and its quick! Rooting is VERY easy on this particular phone & the instructions can be found here in the android development section of this phone model. Or you could simply just take the phone back and ***** to sprint about it and maybe they'll issue you a new unit.

I prefer not going to sprint at all simply because the only store with a repair center here where i live i worked at and it was terrible, but I need help. I want to know the simplest way to root and revert back to 100% out of the box stock if possible... If not i'll suck it up and go to the store

Do I need to root because this just shows him unrooting the phone?

You have been such a blessing! Thanks so much for being patient and dealing with my ignorance...

lol don't know yet.. but you are definitely more of a professional than I am so I am taking your word for it

I appreciate it. If I do encounter any problems I will let you know but so far so good. It's pretty easy to follow

It worked! Thanks again

Thanks! Being that I'm a pro now I will look into the whole rooting and flashing rooms. I even got the lingo down lol

Question though... Do I flash roms the same way as in the video or is there something different I have to do?

[Q] Data and syncing turn off when screen is off.

After running on a stock ROM(but rooted /w TWRP), I decided that I wanted to install a custom ROM so that I could tether if needed. Well, big mistake. I wiped stock and accidentally wiped my stock backup when going to flash a custom ROM and so far I've tried XenonHD, Jedi X19, IllusionROM, and now I'm on a Stock-Tweaked. So far, every single ROM has caused massive delays in receiving SMS messages and syncs from stuff like gmail.
Data is definitely working, and i've tried both the epc.tmobile.com and fast.tmobile.com APNs but my phone keeps hanging when it trys to send some texts and, if I have texts "waiting" to be delivered to my phone, I only receive them once I turn on my phone screen or only if the screen is on. So what the hell is going on here?
I am not installing anything on the ROMs aside from what's coming with them. The issue presents itself immediately after I boot for the first time and set up gmail.
It seems that if I go to 4G/3G/2G mode only the issue doesn't persist. Or at least not as much. But then I can't use LTE! =/
I've tried multiple ROMs that were TW and multiple that were simply AOSP. So 4.1.2, and 4.3 roms. I even accidentally flashed a 4.2.2 AOKP ROM.(for the Note 2, of course). I am not back to the stock Odin recovery with a root injected stock image but i'm still suffering from the same problem =/. This really sucks. Is there a way to completely wipe EVERY trace of an older Android install off of the phone?
I haven't tried the total stock bare bones one yet because the mirror is so slow, it's currently at 641 / 895 MB downloading and has about an hour left. It's the 4.1.2 June release.
I'm attaching a logcat to this post as well, from when I had the screen on, locked it, turned the screen on, and unlocked the phone.
I just realized the logcat is about 58k lines long, so I'd start from the bottom and go up since that was the most recent phone activity of when I actually went through the motion described earlier.

Let me know what happens when you try the stock sw.

I had this problem is well. I had to call at T Mobile I told him I was getting long delays in my text messaging, yes I know you're not getting delays it's only happen to you when your phone is in sleep mode. I told him I already did all the normal stuff to correct the problem. they reset their network connection. That fixed it for me. Hopefully your problem is that simple.

[Q] Mobile Data not working on CM11..

I am kind of new to the Android world (about 3 months) and about 2 days ago, one of my friends told me that getting CyanogenMod11 is the coolest thing ever, so I went over to his house and he rooted my phone, then he installed CyanogenMod11 via the new installer. I have the Galaxy S3 AT&T and everything was going good. When I was walking home, I turned on my Mobile Data in Settings>Data Usage and when I went into the Google Chrome app, it said "You are offline." I went into many other apps that require internet connection for example, I went into Instagram and it says "Couldn't refresh feed." I got home and I logged into my wifi and then Chrome and the other applications needing internet connection worked again, I went back outside far enough to where I get disconnected from my wifi and then I turned my mobile data on just to find that it did not work. [Note : Before I left his house, I went into Tumblr and my phone froze then it rebooted. When it turned back on, I was getting all of these messages appearing on my screen saying, "Unfortunately com.google.gaaps (or something like that) has stopped working." I got a few of these messages all relating to Google applications like on YouTube the app would close when I opened it. I rebooted my phone and that seemed to fix this problem.] I need to know whether I should look for a way to get my phone back to stock or if there is a fix to my problem.

I cannot seem to find a tutorial on how to flash a modem onto my ATT Galaxy S3 and I have pretty much given up on searching for one unless you can supply me with directions on how to do so. I appreciate your help and sorry for being a "noob" at rooting, modding, flashing, and Android overall.
EDIT-- I found out how to flash a modem onto my device and it did not fix my problem, I now have resulted in looking for a way to get back to stock and forget about rooting, modding, flashing, and just sticking to the stock Android and accepting how it is..
