I'm having issues with my data connection after unrooting my phone for the LP update. I used the the TOT file method to unroot my phone, and didn't have any issues with the process. This method takes me back to the 10c version and everything works flawlessly. When I take the updates though, everything looks normal, boots up fine, but won't connect to anything but WiFi. The data signal bars have a tiny refresh circle rotating above for a few seconds then goes to a red x. Ten in a few more seconds it starts over searching for a signal. This happens on every stock ROM I flash now too. Only the 10c ROM, CM11, CM12, and AOSP based ROMs work. I'm not a complete noob at rooting. I've been doing it since my og evo 4g, but this is the first major problem I've had. Currently I'm staying with the unrooted 10c ROM until I can find a fix. Everything is working, but I constantly have the update notification which is annoying. Anyone have any other suggestions? I've tried using the TOT file method and the KDZ file with the 10R method. Thanks in advanced

Have you tried my fix? It might work for you. Try it and let me know. Before trying it though make sure your APN is correct setting for Tmobile. If so try the fix on my thread:
http://forum.xda-developers.com/tmobile-lg-g3/help/lte-lollipop-issue-fix-t3075637
Not sure how I missed your thread. I'm trying it now and I'll report back in a few.
That did the trick!!!

Hi guys,
My f400l has been experiencing issues for a while now. One morning, I woke up to find an unresponsive device. Took out battery and turned it on again to find that the device had partially reset itself (ie. going back to stock launcher and layout, missing apps). Device was still rooted so I tried to restore apps and settings via titanium backup. However, phone kept freezing throughout restore process.
Next, I decided to flash back to stock. This is when i noticed that wifi would remain at 'wifi turning on' but never actually turn on. Additionally, bluetooth could not be turned on. I then upgraded to lollipop via normal firmware update from lg software on my pc. Phone then would freeze after every 2 mins.
After trialing many rooms, I am now on cloudyg3 2.1 but wifi/bluetooth are still not working and phone still freezes occasionally (usually at the beginning of the day).
Really at a loss here, can anyone suggest what seems to be happening and what I can do about it?
Thanks everyone!

If flashing the modem, wouldn't I need to first revert back to stock kitkat?

Argh! So i tried flashing and upon reboot, phone came up with a security error. Currently reverting back to stock via download mode. I couldn't get back into recovery. Did I do something wrong? Thanks for the help so far tho!
EDIT: ahhh just realized i flashed a kitkat kernel, woops! Will see how things pan out for now
So i went back to stock and flashed a kernel but that didn't seem to help. Can't seem to find a zip file for kitkat baseband so I'm a bit lost as to how to flash a modem.
One thing I also noticed is that fact that i cannot access recovery via hardware buttons? I use power and volume down but the combo doesn't work. It just boots normally?
Well, I followed an XDA thread to SIM unlock the M919. It involved downgrading from 4.4.4 to 4.2. and I successfully unlocked my device! But now I have no Wifi... I tried flashing every single modem, every firmware (Official TW ones via Odin, every custom rom using TWRP). They flashed well and everything worked besides the Wifi. I've found some threads from people with the exact same problem (they tried to unlock it using the same method) but those are old threads with no solution.
I've spent 24hrs reading and flashing and wiping and reading again. Any ideas?
Many thanks!
Anyone? If you find me a solution I will Paypal you 20 bucks!

I am having the same issue. My phone was already unlocked though, so no downgrading on my part, but I think we're having the same issue. Is yours showing connected, but usually getting time outs or disconnecting?
My issue happened when I flashed from stock 4.2 to the GPE rom for 5.1. Wi-fi issues. Connected, but exclamation point saying that my connection wasn't working. So I flashed a different rom (candy) and still, I have issues. So I went back to 4.2, stock everything. Stock bootloader, stock rom, stock radio. Still had issues. So I decided maybe flashing a new radio would work, so I flashed NH7 and NK2 (broke my audio). Still didn't work. Realized my bootloader doesn't match the modem, so I flashed 4.4.4 stock bootloader and stock NK2 modem. Tried it with the candy rom. No go. I tried the 4.4.4 stock ROM, wifi still has that stupid exclamation point. I've even gone so far as flashing both the bootloader and the radio over 5 times in one go (with battery pull each time) to see if that will work (starting to go nuts, I guess), but still, no fix.
I've had a temporary fix with Tasker (Connect2wifi), but it doesn't work when my phone is on idle, so I don't get any notifications until I actually wake up my phone.
I'm starting to wonder if it's the physical wifi radio (antenna) inside my phone that's broken. But then I wouldn't be able to connect at all if that's the case, right?

No, unfortunately my issue is very different. I know it isn't hardware related. I've never had any issues with it until the second I downgraded. Wifi just doesn't turn on. When I click on the button it just tries to turn on and after a couple seconds it turns back off, without even detecting any networks. This happens no matter what rom, version of android or modem I use. Downgraded, upgraded, tested every single modem and rom via TWRP and Odin.

I have the d851 T-mobile variant with 3gb, and while I have no issues flashing whatever rom I want, none of them happen to be stable. Originally my phone would just turn off and I would have to perform a battery pull to bring it back. It could happen at anytime, while it's sitting on my desk without being touched, or just browsing facebook. I bit the bullet and installed the official OTA and rerooted the phone and tried a number of other roms. They still crash, however I have been presented with a crash manager that allows me to reboot with the volume key instead of having to do a battery pull. Even the touted Cloudy G3 rom crashes on me. Quite literally, the only rom that works is stock. I have been searching everywhere for an answer and my eyes are about to bleed. I have never seen anything like this...does anyone have any insight?

Well I recommend a clean TOT or KDZ flash. Hope this will fix your problem. Please do follow this post to flash TOT or KDZ http://forum.xda-developers.com/showthread.php?t=2785089 then flash any other rom. Thanks!
Someone showed me the thread with the 12.1 cm rom and the .img for the recovery is it okay if I use flashify to put the recovery on my phone instead of using odin after rooting? Or does someone have a .tar recovery for the L520 in a drop box somewhere? also do I need to update my firmware before flashing a rom? I think I'm on firmware na7 on 4.2.2
it's fine, trust me use flashify. Odin doesn't flash .img files. No, you don't need to update your firmware, it's going to be flashed over anyways.
Seemed to work fine. That cm 12.1 rom still working okay for you?
There's a few little annoyances but it's working okay otherwise. I get an exclamation point by my bars sometimes and have to reset the apn to fix it. GPS has some issues so it's become more a roadmap than actual guidance and I can't send mms but that's not really an issue as I have unlimited data and can just facebook messenger as a workaround. I hope that these issues get fixed but I understand that alot of 5.1 roms have issues with the exclamation point thing and even some unrooted 5.1 phones have the problem. It would be nice to see a fix for these issues but I don't see anyone making any more roms for this phone and the guy that made this rom seems to have landed a job with cyanogenmod and is too busy to update this rom. What a shame but at least I have 5.1 now.
Hmm I suppose I'll stay at 4.2.2 till I feel like flashing 12.1 thanks for all the info. You don't have any overheating issues or random restarts right? Also how does the GPS not work well?
No overheating or random restarts. All things considered its a pretty smooth rom if just a little incomplete. I only tried using the GPS once and it came up with my location and the route for where I needed to go but when i was driving along the GLS was not updating my location. It may have been just a one time thing, idk, I havent needed to use GPS since.
Cool do you know a way to go back to stock if I don't like the cm 12.1 rom?
Hey there,
I was wondering if anyone could maybe figure out this issue which has been troubling me for about a month or so.
I have ran marshmellow before absolutely fine however decided to flash lollipop back on my phone as I felt the battery life was better.
Anyway, whenever I come back to any version of the Marshmallow roms, i'm greeted with not being able to set a lockscreen (lockscreen has crashed), I cannot uninstall apps without a force reboot and I cannot access the security settings on the phone without it crashing.
I've tried wiping pretty much everything and it seems to be on all roms. I've tried multiple from fresh.
Any ideas?
Much Appreciated
Issue fixed, flashed a new KDZ and seems to be working

DO you know if flashing back works on verizon? I loved this phone until MM...
Also any insight on the steps, did you just use LGUP and get the KDZ off Sotragecow?

@zwalk - sorry for the late response. I did exactly that. Seemed to fix everything. I recommend trying 20f or 20g if it works with your phone as it seems to fix battery issues.
