Root Random Reboot causes

[finndo77]

I want to start a thread (so I did, as you can obviously see at this point) so we can log possible and confirmed causes for random reboots. I think there are multiple issues at hand, it happens in all LG stock base Rom builds, and obviously is caused by multiple problems, some of which have "solutions" found. Since a lot of people are having this issue (on this forum at least, by "a lot" I am referring to the percentage of people posting saying they have random reboots vs. the percentage of people not saying they have random reboots).

I'll slap a poll on here so we can try to get a better sense of the issue. I will also reserve the second post in the thread for listing causes and any possible solutions for them.

 

[finndo77]

So far the following issues have been reported as causing random reboots:

1. any issue - fixed by reflashing the Rom
2. any issue - fixed by not using Titanium Backup to restore App Data
3. any issue - fixed by not using Rom Toolbox to restore App Data
4. ADW Launcher - fixed by uninstalling
5. installing more than 7 apps at a time - don't do this, some people have problems, some don't (think of it like drinking and driving, it sounds like a good idea at the time...)
6. over heating - fixed by keeping it cool (yes I have put my LG Spectrum in the Freezer)
7. putting phone on metal desk - fixed by uninstalling (freezing too?) carhome.apk

Restoring data from rom toolbox causes issues too. ADW didn't cause issues at first when I didn't restore data, but did after a week of use.

i cant really vote because none of the options apply to me. But My reboots have gone away. Ever since I started reflashing the rom after I get everything setup my reboots cease. I always use TB pro to restore apps with data and I use RTB pro to restore misc. data. For me the reflash works.

I've been on BO 3 for over a week with 0 reboots. And I'm a heavy user. I even have been doing some gaming lately.

Have not resolved mine. Today it was rebooting with damn near opening any app, then it was working fine, it even did a full freeze and I had to pull battery. I still have to try to re-wipe and flash and set it all up again from scratch to see if that resolved it. Been to lazy to do so though. The thing I have noticed though is maps and nav make it reboot very very frequently, also loading anything too fast after a reboot wants to make it reboot again.

I can't get the car dock app to freeze any more. That messes with me a lot.

dont wipe data yet. Just try flashing the rom again. You'll keep all your apps and settings and it may fix your issue. Always does the trick for me

 

[steamer86]

Tried that a few times, didn't work. Wiped, erased data, dav, ect ect. Gonna start from bare rom and ONLY install and no restores. Will tell ya how it goes.

I got non-stop reboots when I would put my computer on my desk at work. The desk is metal and I am assssssoooooooooming it was because of some magnetism causing the internal magnetic "receptors" to get confused. I got a block of wood (2x4!!!) as a desk cradle. haha, cradle. The bootloop went away.

One day while perusing this forum someone mentioned the carhome.apk. I thought to myself, "self, delete that file."

Oh yeah, I am a dork. Anyway...

I deleted that file and now my phone can be safely placed on my metal desk at work and it no longer bootloops.

Now, I have gotten random reboots also. I have gone for at least 2 weeks now without one until today. The temperature outside is easily 93

I am in the same boat kind of. Since i bought my phone in January i have had 2 reboots i think. Both while using the messaging app.

Something else i was thinking was where everybody got their phone from. If there is any pattern there. I personally got mine from the local verizon store. I know there are a few people who got theirs online from costco and such for next to nothing. Just curious if there is something to it, defect devices or something to that nature.

I have mentioned before, but I get a reboot everytime I shut down Wifi tether. I've changed settings and it doesn't help. I have un installed and reinstalled. I'm on 3.0.

 

[finndo77]

this past weekend I did a reinstall of my EvenLess super bloated 3.0 Rom (EvenLess version of BO 3.0 plus all my apps! comes in at 875MB right now, zipped!) I had my normal "random" reboot (1) about 2 minutes after the first bootup, another random reboot (2) after I added my Google account, another random reboot (3) while the play market was updating 21 apps, another random reboot (4) while amazon was updating 7 apps (I swear I added the newest versions backed up by rom toolbox before flashing...), which started while there were still a couple left in the play market to update. Then I had another random reboot (5) while the play market was finishing, but after amazon finished. I had yet another random reboot (6) a few minutes after all the updates had finished, I was already in bed and had the phone laying next to me. Then I started logging in to things, I got my Google voice account added, opened Titanium backup to trigger the Pro version, same with Fancy Widgets, then I imported my fancy widgets settings (from within the app) and got a random reboot (7). I think I had one more random reboot (8) while I was setting up some other things. Then I went to sleep.

I finished setting things up the next morning and had another random reboot (9) almost as soon as I turned the screen on, this one locked up the screen about 10 seconds before restarting. Then I did not have another one until this afternoon.almost 3 full days good (I did not restore anything with titanium or rom toolbox).

This after noon I had three all within 20 minutes or so, I was on the phone with verizon for 47 minutes dealing with a disappearing account credit on my old verizon account, within 2 seconds of pressing "end" to hang up at the end of the call, the phone rebooted (10), it was at about 39% battery. When it came back up I unlocked it to send a text via google voice to my wife (I don't have messaging on my plan, saves $30, or $10 for 1k), I noticed Lookout mobile started an app scan on my phone, and it rebooted as soon as the google voice inbox screen came up, well almost came up... it looked like a 3D image from a comic book in the 80's, everything was shifted about 3-5 pixels down and to the right and I swear I saw one set was red and the other green...then 10 seconds later, was random reboot (11). After that I just gave up and put my phone on my desk and went back to work for about 5 minutes and I decided I wanted to run aLogcat and take a look. I clicked download on aLogCat in the play market and the phone instantly rebooted (12)... not happy I was... hmmm?

When it came back up I got aLogCat installed and opened it, I exported the file and then cleared it. I took a look and I can see somethings but really have no idea what any of it was, I was very disappointed that there were no time stamps.

anyone that is interested can view it from here: http:joelperryproductions.com/spectrum/logcats/

there is also a 2nd log, but the first was exported, then I cleared the log almost immediately after I installed aLogCat (I don't know if the logs evaporate if some logcat proggy is not installed, so I don't know if there is anything useful in it.) I saw a couple of SQlite disk IO errors, but not much else of use to me.

any ideas on how to edit the poll options? I'd be happy to change the options to first person, and add #5 "I've had random reboots, but not in a long time"

also, I ordered mine (this one anyway) from NewEgg the second week in march.

finndo77, maybe it's your slimmed down versions that are causing your reboots. or you have a defective phone. Run stock for a few days and see if you get all them reboots. If you are then you have a defective phone. Get a replacement. Obviously there are tons of us that are not having these issues so something isnt right.

 

[finndo77]

I tried not modifying with stock, eclipse, broken out 1-1.3, had similar issues with all of them. It seems that the longer I use the phone without reflashing, the less I have reboots. As I said, it is mostly the first 24 hours or less then no reboots for days. On Broken Out 2 I went almost two weeks without any restarts, random or intentional. The v6 stock rooted was far far worse, it rebooted almost twice an hour all day. For the two days before I went back to Broken Out.

It could be the phone, this is my third LG Spectrum...

I uninstalled ADW EX and that reduced my seemingly random reboots by about 95%.

I still get the occasional reboot, but it is usually when my phone is trying to do too many things at once. As an example: this morning I opened Pulse news reader and while I had it reloading all of my feeds I tried opening an old article. After a few seconds of a black screen, the phone rebooted. My fault.

By and large, the reboots are gone now that I'm no longer running ADW EX. I'm disappointed I purchased it. And once I'm using ICS, I'll probably never use it again because I'll most likely end up on Apex or Nova. Bummer.

 

[WaVeS]

How did you go about deleting cardock? I used ROM toolbox earlier today and thought I had killed it, UNTIL I opened tapatalk just now (5 mins ago). The icon piped up again, causing my keyboard to close and eventually tapatalk to fc. Boo. Do I need to get root browser again and delete it that way? If so where is it located?

 

[steamer86]

Fresh clean install, gmaps/nav rebooted it, flashed BO over again and it happened again.

Again, Stock isn't rebooting.

I use Root Explorer. In the settings, you have to check the 'Up to Root' box. This allows you to get to the top level folder (root folder). Inside the /system/app/ folder you will see the CarHome.apk

Delete!

Mmmyep. Deleting adw isn't necessary but keeping it from running will stop reboots.

 

[revdmv]

Well to throw another data point in the mix, I tried a couple of things I've read in the other threads.

First I reflashed BO 3.0, then I moved the CPU to 1.8 and conservative. So far after flogging the phone with maps and games, no reboots, and battery life has improved.

 

[MrB206]

Overclock and conservative... Interesting. I never thought of trying that.

Works great for me. Been running like that for a while

Went to the folder, it's gone. I must have deleted it with ROM toolbox. Strange that it continues to pop up. I've only noticed it when I use a keyboard on dolphin browser, sms, and tapatalk. Probably others as well because I've randomly had the screen flicker and the flash of a keyboard while playing games. I'll just flash it again like everybody else.
