I haven't had any camera related crashes. I've also seen somewhere else people saying video chat doesn't work. They were talking about skype and facebook i think. I've been using hangouts and open camera without problem.

My primary crash is blue screen external modem, but recently the phone has been taking to blinking it self off randomly, while on external power or not. But it will be off not just frozen, plug it in and I get the power off charge screen.

I'm starting to think about going back to CM11. 12 just keeps getting worse as time goes by. Jan 18 build was great, don't remember any crashes, just missing features, like expandable volume. Tired of trading features for stability.
[AT&T LG Optimus G] topdawg7793:
You're undervolting too much? I usually get similar errors when I over-undervolt.
[AT&T LG Optimus G] RodneyMcKay:
Interesting thought, I haven't changed anything from what I thought was the default. TricksterMod is disabled. Wish I could be more specific with TricksterMod of which settings to auto apply.

Also I can't seem to get the max cpu clock to stay at 1.5ghz. It keeps dropping down to 1ghz + or - 100mhz.

Tried SolidGeeb kernel but switched back to cm stock as it didn't fix btmac or help battery drain and heat problems.

--- update - - -

Checked settings looks like stock kernel doesn't have voltage control. I'll probably try SolidGeeb again with this idea.

I was getting external modem sub system crashes daily for two weeks until I flashed solid kernel , haven't had one since.
[AT&T LG Optimus G] maur1c10:
i have my phone rooted and twrp installed, im using android 4.1.2 can i just install this or do i need anything else?

can i install this and it will work in my country (El Salvador)?

in twrp i dont see an option to install from external card, just internal
[AT&T LG Optimus G] rashp12:
We all appreciate additional features that get dropped in each nightly. But, the stability is the most important aspect which gets better with each nightly. Though, the snapshot build is one in time represents milestone for the stamp of approval for the stable build. Question, are we going to have snapshot in next few weeks or CM12 nighties are very stable and everyone is happy to continue installing ?
[AT&T LG Optimus G] harshmehta29:
Hi everyone Been a Lg optimus G user since a year, now just began flashing the phone as i was too bored with the old android.

I used TWRP 2.8.3 for flashing

Flashed cm12 04032015 but now facing many problems, even tried cm12 08032015 but it keeps on crashing

1) Wifi just wont connect to any network no matter what

2) Gapps LP 20141212 always fails to install in TWRP

Can someone help me out of this the phone has now become useless and I feel i shouldnt have flashed and tried all this but I am sure there is be a solution to this....
[AT&T LG Optimus G] maur1c10:
the phone dont let me activate charge only mode in usb connection, i need to activate it to root the phone
[AT&T LG Optimus G] topdawg7793:
THERE IS ALWAYS A SOLUTION! Welcome to the forums.

Did you come from Android 4.0.4 or did your phone already have 4.1.2? Between 4.0.4 and 4.1.2 there was a change in the modem. If you're coming from 4.0.4, you might not have the new modem and that could be the cause of your Wi-Fi issues.
[AT&T LG Optimus G] harshmehta29:
Thank you for the reply. I came from 4.0.4 and then did all the flashing hence as u said the new modem is not flashed on this phone.

How can this be solved?
[AT&T LG Optimus G] harshmehta29:
Got the wifi problem solved.

Shifted to stable cm 10.2 for now till cm 12 becomes more useable.

Thank you
[AT&T LG Optimus G] rashp12:
Stability is relative term but long as specific ROM build don't crash requiting re-boot and basic functionalities like wifi/cell/Bluetooth connectives, productivity and widely use apps, sleep/wake-up, acceptable battery performance, etc works without issues than that ROM is acceptable and stable to use for daily use. Rightly, we see issues posted here about CM12 nightly but please post experience here or other thread if you are happy with and certain nightly happen to have those functionalities work well because good to hear from happy campers.
[AT&T LG Optimus G] topdawg7793:
Just look in the general forum for jelly bean modem. Go to it, download the jelly bean modem, flash it and reboot. That should fix it.
[AT&T LG Optimus G] 1800yolk:
I seem to have stability issues fairly often too. I thought I had flashed the jb modem but it looks like I haven't? Also, anyone using a kernel that works better than this? thanks
[AT&T LG Optimus G] RodneyMcKay:
I'm pretty sure I did the radio upgrades along the way, as I've been following cm on this device as long as it has been possible. Here is what I am running.

This is on a week or so old cm12 build.
[AT&T LG Optimus G] RodneyMcKay:
That being said, I have been getting green screen ap watchdog bark, crashes periodically since switching to SolidGeeb and resolving my blue screen crashes from earlier in the thread.
[AT&T LG Optimus G] 1800yolk:
thanks for the info! I only occasionally crash, maybe once a week, but I have been having an issue with Google voice not working unless I force 3g, so switching basebands might help
[AT&T LG Optimus G] ericb3800:
Me too, green screen instead of blue. I recently lost deep sleep too.There's a new solid kernel I haven't tried yet. Fingers crossed.
[AT&T LG Optimus G] Rockwig:
Where is this new kernel?
[AT&T LG Optimus G] ericb3800:
Clementinox mentioned a new 1.6 solid kernel update in his liquidsmooth thread, no such update yet in the solid kernels thread. Must have been a typo.
[AT&T LG Optimus G] jmoss1972:
Has anyone tried the latest nightly, and if do can you get past the set up wizard?
[AT&T LG Optimus G] redseablues:
Same issue. I downloaded the latest nightly build, wiped the phone clean & not able to progress beyond the cyanamodgen account login :(
[AT&T LG Optimus G] WESTdad:
What was the date of the nightly? I tried 3-24 and it didn't work but I was going to try 3-27 so I thought I would ask first. Thanks
[AT&T LG Optimus G] redseablues:
Tried 25 & 27. What I did was, I downloaded a stable version from 12'2014 and then upgraded to 3/27 version.
[AT&T LG Optimus G] WESTdad:
Well I guess I'll have to try again later then. Thanks!
[AT&T LG Optimus G] big_dog1968:
It installs and boots, but the initial setup crashes before setup can complete at the same point, every time. I had installed an earlier version, without issue, before. Did a full wipe prior to installing. Tried to reinstall and the same thing happened. What could the problem be?
[AT&T LG Optimus G] jmoss1972:
Going to try there latest nightly to see if I can get past the set up wizard.
[AT&T LG Optimus G] emepher:
Same problems here, with nightlies ranging from 3/10 to 3/31. I was having issues with bluetooth music pausing all the time and yesterday the screen lock started acting stupid, so tonight I tried a clean install and now I can't get through the setup wizard, even with the older builds. Very disappointing. I had been running the 3/17 build, so I don't know what is wrong now - an issue connecting to CM, since the setup wizard needs to be online?

I've mostly stuck with CM ever since I got my HTC Dream/G1, but now I might have to switch because I can not get it to work with the e970 anymore, and I'm really getting tired of having to mess with it. I want to be done experimenting all the time and just want it to work. Maybe I'll just go back to KK and deal with it until I get so sick of this that I get a new phone.
[AT&T LG Optimus G] Shelnutt2:
Looking into he crash on setup issue now. Been working on ls980 and ls990 but its time for some lgog love. I'll fix this and then get the 12.1 branches pushed.
[AT&T LG Optimus G] RodneyMcKay:
While you're at it, could you please take a look at the Bluetooth mac address issue and see if you can find anything obvious?
[AT&T LG Optimus G] boulos:
So, I was originally on CM11. I had the bluetooth mac issue, ran the script and it fixed it. I got tired of CM11 crashing, so I decided to give Artmod a try. When I installed that, I had the bluetooth mac issue again. I tried the script and it did not work. I went to the international forum and someone suggested to install it manually. Did that and now it works for artmod. Maybe you can try it on CM12?

[AT&T LG Optimus G] RodneyMcKay:
I'll give it another go, but I tried manually running the steps as su, and I hit a wall with the dd write to the misc partition. Illegal seek
[AT&T LG Optimus G] Shelnutt2:
Setup bug has been resolved. It'll be in tonight's official builds.
[AT&T LG Optimus G] RodneyMcKay:
I tried the steps manually last night a few times without success. I was hoping for a bit of luck, I noticed that my IMEI number had been wiped null, so I found my correct efs backup(labeled it this time) and restored that. Unfortunately that didn't have any affect on the BT problem.

Which incorrect mac address was artmod giving you? 41:4E:44:52:4F:49 or 00:00:00:00:5A:AD ?

The 41:4E is the address that the script seems to be able to fix. The 00:00 is the problem I'm getting on cm12. It seems to be using a reference other than what the script tries to repair. Besides that the last step in the script the DD injection, doesn't seem to actually write to the partition. If you do a DD read after the write to verify, no changes were made. I might try rebuilding the script with some manual steps so that I can flash the partition from recovery. That way if it is a new android security issue, android is out of the way. This is my only phone however and I don't want to take much risk in breaking it.
[AT&T LG Optimus G] boulos:
It started with 41:4e. That's right , I forgot the lollipop address was different than the kit kit. Sorry about that. As far as messing up your main phone, I completely understand. I thought I bricked my niece's S4. I hope you find a solution. Good luck....

406 Nightly

CM Updater refused to recognize 4/06 nightly. Needed to manually download and install.
[AT&T LG Optimus G] jimi_pooh:
Installer recognized 4/06 for me. Anyone having GPS issues lately

Update: 4/06 fixed GPS for me.
[AT&T LG Optimus G] emepher:
Big thanks, Shellnut! You are the best. The 4/6 nightly installed flawlessly for me. Did a clean install but it was able to grab app data from the backup I made a couple weeks ago, making it super easy to get everything fully set up.

Haven't tested BT yet, which was acting funky with my car. Sometimes it would work perfectly, other times it would pause/stutter periodically and repeatedly when playing music. I assume this was the MAC address issue others have mentioned.

The quick toggle tile to turn the screen lock on or off is still not working - it was until a week or two ago, for me. This is one little tiny thing that is driving me nuts, because I need to turn the screen lock on/off several times a day at work because the phone has to reside in my pocket at times. Everything else is good!
[AT&T LG Optimus G] rashp12:
"Shelnutt2" is unbelievable. I can't thank him enough. To appreciate, please thank him and donate whatever you can.. We need LG e970 stay updated and working well with CM12 nightly and Shelnutt2 involvement makes it easier/painless. Thank you Shelnutt2.
[AT&T LG Optimus G] emepher:
Anyone have any new insight or ideas regarding the BT MAC address issue? I get a MAC address of 00:00:00:00:5a:ad and BT does not play nice with other devices. It will normally pair and connect fine, or so it appears to, but then it pauses/stutters/whatever when streaming music to another device.

Any solution other than to dump CM12? Is this a problem with other AOSP roms? My only work around is to carry a separate device for music, which is unacceptable and defeats the purpose of having such an otherwise nice phone. To make this problem even more confounding, my problem didn't crop up shortly after reboots when I was running earlier builds. Now it happens all the time, even right after a reboot. I want a new phone so bad but the $$$ required just isn't there right now.

CM 12.1 on the horizon?
[AT&T LG Optimus G] RodneyMcKay:
I haven't even bothered repairing my devices yet. I was holding out hope that this would get fixed. I think it's a big issue, especially considering more and more states are going to hands free driving laws. I just this weekend "accidentally" did a full wipe on my phone using the 4/11 build. The BT MAC problem is still there. I had some hope it was an upgrade path issues, but that's not the case. I did manage to fix my app crashes at boot doing this however, at least until i reverted to my old backup to get my tasker profiles. Then on restoring the new backup programs started crashing again.... fortunately it seems uninstall and reinstall from the store cleared that up.

The Mako based CM12 also has the issue, but with a different address. There the BT address came in as 35:32:34:66:34:38. I also had the wrong wifi mac with MAKO also, but that's a whole other problem.
[AT&T LG Optimus G] xike456:
Anyone has problem with wifi connection? My phone keep disconnects wifi AP when it idles or sleeps. I try to set keep wi-fi on during sleep to always but it doesn't work. Sometime it still connect to AP but cant receive data, so I have to turn wifi off - on then it work again.
[AT&T LG Optimus G] Buscador:
Yes, I have the same problem, primarily overnight.
[AT&T LG Optimus G] Chum.zuizui:
Me too
[AT&T LG Optimus G] milindchitale:
Hi,

maybe you should have a look at the advanced settings for your wifi.

Under settings->wifi-> look for the three dots on top right of wifi tab.

there -> advanced-> keep wifi On during Sleep . change to Always from never or only when plugged in.

That should do the trick.

regards and all the best

CM 12.1 Unofficial

Just for grins I googled "cm 12.1 for optimus g" and got this website:

https://www.androidfilehost.com/?fid=95916177934556443

Downloaded the rom and installed "gapps-5.1.x-20150404-minimaL-edition-signed.zip" from here:

http://xdaforums.com/android/software/gapps-google-apps-minimal-edition-t2943330

and it's working. My bt mac address is " 00:A0:C6:f1:98:46". I guess that's OK. Gmail is working also.
[AT&T LG Optimus G] emepher:
Thanks for this! I have no idea where this came from, and it is "Unofficial," but I'm going to look into it more and may try it. Interesting...
[AT&T LG Optimus G] RodneyMcKay:
Do you know if this is your hardware mac or some other incorrect address? It's great that it's different than previous errors, but if it doesn't match the hardware it's not a solution. The first 6 digits of the mac are supposed to be the vendor code my real mac start with "50:c8:00", so if your's is proper our ships are from different batches minimally. I've seen ethernet cards with different vendor codes before but still be the same parts.

if you run "btnvtool -p" from a terminal it will return your hardware address. I don't remember if you need to su to root or not.

I'm interested to try this build, but don't expect I'll have time this weekend.
[AT&T LG Optimus G] alliance1975:
Btvntool -p yields --board-address 14:40:EF:b0:1:0
[AT&T LG Optimus G] emepher:
I have no idea if this helps, but I'm running that CM 12.1 build now. It seems to have cleared up the BT connection issues I was having with my car.

My BT MAC address now also begins with 00:A0:C6, with the rest being different. Btvntool -p yields something completely different, though it also begins with 14.

I have not noticed any issues yet with this rom, but it hasn't even been 24 hours. So far I am very happy with it because BT is working fine and I am no longer having trouble enabling/disabling the screen lock, which was my other main problem with CM 12 nightlies.

Should we be discussing this somewhere else, or is this okay here since this CM 12.1 may be making progress against some unresolved CM 12 Official bugs?

Also as a side note, I tried the Aroma LP GApps for the first time, from the same link, instead of my usual PA GApps. Nice installer/selector, and everything I've tried is working, but haven't had time to do much yet.
[AT&T LG Optimus G] topdawg7793:
"OMG there's a CM12.1 build just for our Geeb!"

-_-

If you check the Android Development forum, you'll see a post that talks about these builds. It should be noted that the kernel for those aren't based on GeeProj. That thread is probably a better place to discuss that build than this thread, which is meant for official CM12 nightlies...
[AT&T LG Optimus G] emepher:
Delete. Edited to remove me coming across like a jerk.
[AT&T LG Optimus G] RodneyMcKay:
I agree with the original version of you post to an extent. We are trying to use the other build as reference and comparison to find a cause and resolution to an issue with this build. So for topdawg7793 to suggest we stop is uncalled for. Sounds like you have been having further BT issues beyond the mac address issue however. I tried my A2DP headset the other day and had no noticeable issues. I haven't yet tried to reconfigure my car.
[AT&T LG Optimus G] ronasimi:
Any issues/questions/comments about my mako base cm-12.1, go here
[AT&T LG Optimus G] emepher:
Thanks, and I am really not sure about the BT issues I was having, except that I only experienced them with official CM12 nightlies, not with CM 11 or with ronasimi's 12.1 builds. That and the screen lock acting a bit wonky were my only real issues I was having.

I'll keep an eye out for new official builds, and check back in this thread. But for now I'm quite happy with where his unofficial CM 12.1 is, so I will not continue to clutter this thread anymore, unless I come up with something of value to add to the discussion.
[AT&T LG Optimus G] RodneyMcKay:
I finally got around to some bluetooth testing in my car today. BT on CM11 was working fine. CM12 with this Mac Address problem completes pairing ok, but afterwards very little works. When trying to call from the car, the phone beeps in error and fails the call. When receiving a call the car displays the number like normal and when answering the phone picks up, and the call seems to be routed via bluetooth, but neither party can hear anything.

I wonder if this is all caused by the address being wrong. Is the car still trying to connect to the correct address? Is the phone still sending packets with the correct address and the car not accepting it? 1 test/answer many more questions.
[AT&T LG Optimus G] rashp12:
Other than Bluetooth MAC pairing issue posted here, is it safe to say that there are no major issues effecting current OFFICIAL CM12 nightly ?
[AT&T LG Optimus G] 1800yolk:
I still get slowdowns/lock ups every day. they're usually brief, and might be caused by an app rather than cm12's behavior, but I certainly didn't have the problem on kitkat.
[AT&T LG Optimus G] RodneyMcKay:
I've got a list of gripes, but they are getting better.

The one "major" thing is the bluetooth pairing and mac address issues.

There is a random/unexplained crash issue, on the stock kernel I was getting a blue external modem, and on SolidGeeb I'm getting a green AP Watchdog. From what I was reading these are probably the same error just reported differently, external modem being generic, and ap watchdog being specific. Haven't been able to track if it is more common after a voice call or not.

Also there is some unidentified wifi issues. I haven't seen any reports with enough details to sort out a possible cause or source...
[AT&T LG Optimus G] RodneyMcKay:
Wifi bug?

This weekend I was out shopping and had little to no cell service, so i was using the store provided wifi. Of course this was 2.4ghz only. Since then I my phone has been disconnecting from wifi and reporting an "authentication problem". When I connect manually with the saved setting all is fine. I'm switching back to 5ghz only mode now. I'll post a follow up after some testing.
[AT&T LG Optimus G] RodneyMcKay:
After a few days on 5ghz I am still getting the authentication problem, and simply manually clicking connect works just fine. I wonder if this is part of the underlying cause for the random wifi dropouts.... maybe it has an issue reading/using the saved key while in sleep?
[AT&T LG Optimus G] Level99:
Not sure if its something in the kernel or the rom config itself, but there's definitely some unoptimized setting somewhere that's reducing a specific application I use down to a crawl. I use Droidsound E for listening to chiptunes (old VGM and the like), and I keep everything of mine in zip files to save space and organize. On unofficial CM12.1 by ronasimi, Stock KK, even Stock JB, scanning runs at normal pace. On the CM12 official nightlies, scanning goes down below molasses levels. What takes about 2 minutes to scan normally takes over an hour for a single file. I'll delve deeper to see if its related to scheduler or something, but figured I'd report it here since that app is make-or-break with me. I really like our old-ass geebs getting official support even now on CM, but I can't code all day without listening to Sega Genesis music :(

What gapps do you guys use, the ones I try always tell me Google play services have stopped add son as the phone boots
[AT&T LG Optimus G] RodneyMcKay:
It's been a long time since I installed. But I still have a file in my roms download folder from https://basketbuild.com/gapps . The older gapps-lp-20141109-signed build. But i've manually updated google play services along the way a few times.

On that topic of play services stopping right way at boot. This started happening to my wife's phone over the weekend. What I noticed was that the installed version 7.3.xx reverted to the "stock" 4.x.x build. Stock isn't quite accurate as her's is a CM11 install with some package installed. This happened a few times as I was trying to fix a battery drain/wakelock issue. Afraid to reboot at this point, but the "google play services" "systemupdateservices" wakelock is missing and the drain is down to 4ish %/hr down from 10% even though it still is not going to deep sleep.

I am running into error while flashing gapps from the links in the main post, I tried several other gapps version, but the result is the same: "Error executing updater binary in the zip"

The only gapps version that successfully installs is the pa version, but then too as soon as I boot in the phone, I run into all sorts of google app crashes.

One of the things I suspect to be causing this problem is the TWRP, on my OnePlus using TWRP 2.8.6 solved this issue, however there does not seem to be a version later than 2.8.3 for Optimus G AT&T.

Any suggestions from the community to get rid of the errors?

Thank You!

Edit: I was able to flash the gapps after changing the recovery to CWM. So, the TWRP indeed was causing the errors.
[AT&T LG Optimus G] RodneyMcKay:
I been looking for a current TWRP build for a long time, and never had any luck. And the versions I have tried, usually end up overheating and crashing. I'm still running Philz. I know it's stopped production now, but it still works fine for me.
