    Custom launchers seem to be the theme for me. Removing them has made a difference, but there are still occasional reboots occurring.

    Also, I notice custom keyboards may be a culprit as well. Swype with the error tolerance increased and split keyboard with some customizations seem to bog the phone down occasionally and I'll get a reboot. I noticed it with the stock ROM, Broken Out, and Nitro's version 0.2.

    Nitro did mention something vague about removing GoLauncher from 0.2 due to some reboot issue. Has anyone seen more detail on that?

    its not the apps or rom thats making it reboot its the kernel. cus i was on stock with root with stock kernel, i didnt get any reboots what so ever. then i flash blitz kernel, then couple days later it started to reboot, so i flash the popcorn kernel, same thing it reboots

    I did use the stock kernel and ROM for quite some time before, still experienced some, but there were far less. You have a good point.

    Try FTL or Zeam. I use SwiftKey on all my phones, so that's not going to change, but since I stopped using ADW and went to FTL, I had zero random reboots. I had reboots from apps throwing errors, but not the random ones. FTL tossed a random the other night, so I switched to Zeam and haven't had one since. It's not as customizable (using icons/themse from ADW packs), but it's a small RAM footprint.


    Sorry, that's just not true. Some of us have been using this phone and modded roms since day 1, used the 2 kernels other than stock and still encountered reboots. The root-cause analysis so far points to apps not working well will the phone's version of Android and/or the data the app saves when backed up. Restoring app data through Titanium or Rom Toolbox will almost certainly cause reboots, for whatever reason.

    Just a thought, could it be caused by the system files having different names than every other phone?

    And this causing app issues on developers who have hard coded system file names and or locations of the files. Which may be something that a root required app would do (explaining the issues with rtb and titanium)

    Good for you. That hardly is a definite affirmation that the kernel is to blame, since you haven't even tried other roms/configurations.

    Yes I have not tried the other rooms but when I flashed the blitz kernel and popcorn kernel I started to get the reboots. This never happened to me with stock kernel

    I actually found less issues and reboots with the Blitzkrieg kernel. I think it's more about the configuration... Popcorn didn't work well with BrokenOut for me, but did with eclipse.

    Most of the random reboots I have experienced are caused when carrying my phone in my hand along with my iPad. I finally thought about it and assumed that the magnets in the smart cover where somehow causing the issue. I tested this and confirmed the cause. When the phone is asleep, putting it next to the iPad magnets will cause a reboot. If it's awake the car mode will activate. After reading this thread I have frozen carhome.apk with TB Pro. I will do some testing over the next few days and report back if my issue has been resolved. I also believe WiFi Tether is occasionally causing some of the reboots.

    Upload it to Pastebin and post the link here. We can get an idea of what caused the reboot from that file.

    Sim sync error. So it should save those logs in the folder on your sd card... Check to see if it's there. That screenshot doesn't quite say what triggered the call for the sim card.

    Wow, I went over that logcat you sent me. Your phone is CONSTANTLY working/running, which is weird and there are a ton of database errors.

    You have a reoccurring database error "android.database.sqlite.SQLiteException" and the LG MLT app seems to be throwing some errors. What's concerning is NO ONE on the interwebs seems to know what this damn app does. It appears to be a system monitor app, so it *could* be frozen. But please note, I don't know if freezing that app will lead to other issues (like when you freeze 'messaging', you can't send mms); if you start to see adverse reactions, unfreeze it.

    Yeah I was thinking there was something screwy going on. Thanks for the help. The sqlite data error seem to be the biggest one sending errors. Not sure how to deal with that...ill try to freeze that app though. To fix ALL of this I'm thinking I may need to go back to v4 update to v6 and then try BO. I think one of the problems is all that working is causing my phone to overheat and then reboot. Im sitting over here wih a bag of ice kn thia thing to bea able to write this without a reboot. Lol. Quite the mess.

    When v6 first came out I wasn't getting thy download so I called Verizon and they pushed a sim card update to my phone but I still couldn't update. I finally had to go through lgs download onmy computer to update my phone to v6. A lot of work on this little Guy.

    Started I from a re flash and fresh BO and still getting the same errors as before. I guess it's off to flashing back to v4 to v6 and trying again. Otherwise I can think it must be the Sim card.

    Same errors I get, also suffer from constant reboots. Flashing back and forth has fixed nothing for me, only using stock has stopped it.

    Have either of you tried to go to stock v4,wipe data, cache and dalvik and then flash BO3?

    I'm on BO3 and haven't encountered those issues, but I came from v4. Actually, I think I came from Eclipse, but that doesn't matter since I wipe data and cache before flashing.

    Haven't Mr B.That was my next steps though. No other options left. Reflashed BO so many times I can't count. I'll need to pit aside some time to so that though. Limping by on this for now. I'll let I know what I find out. If that doesn't work it's the Sim or the phone hardware.

    Ditto on the SQlite errors, and the log cat goes bonkers non stop never pausing.

    Several of my log cats can be found here:

    Joelperryproductions.com/spectrum/logcats

    If I catch the reboot, I save a logcat as soon as the phone is back up, so the cause should be near the end of each file, with the build up to the issue coming before it.

    I would not be surprised if my messaging with the Rom caused most of the reboots.
