[Q] No Wifi or 3G on LG Optimus G LS970 (Sprint) with Kitkat, stock works

Hi,
My LS970 works fine with the stock ROM (4.0.4) but as soon as I install a custom ROM with Kitkat neither 3G, 4G or Wifi work. I have tried CM11, JellyBam and SlimBeans but all show the same behavior. Does anybody have this working or an idea what could be wrong?
Cheers!

If your on Stock 4.0.4 that should be ZV9 and that radio won't work for JB and any CM Rom's. You need to upgrade your radio.
There are a few options:
Let your phone upgrade to ZVC. It should be trying to do that already.
Or, if you are rooted and unlocked already and have TWRP, then you can flash the radio/modem. I would also recommend using a Stock based Rom to start.
The flashable radio/modems are here. http://forum.xda-developers.com/showthread.php?p=40169203
The Stock Rom I would use is here. http://www.androidfilehost.com/?fid=23212708291680187
So in recovery, flash the radio, then the ROM. It might not hurt to flash the radio a second time before you reboot.

I couldn't go back to stock and use the OTA because I have been told that using the OTA stock update will brick the phone if the bootloader is unlocked. So I have downloaded the file LS970ZVC-M9615A-CEFWMAZM-3.0.10646 from your link and flashed it.
WIFI works now. Thanks! But I still don't have 3G or LTE. Any ideas what else could be missing?
Thanks again! I was already ready to throw out the phone and get a Nexus 5.

Try flashing a stock rom, the one linked above. Then go to Settings>System Updates and update profile and prl. You can also go to Settings>Activate this device after those 2. This is the only way we can update those. CM/AOSP can't do that. That should get you going.

That did it. I have Wifi and 3G (no LTE but I can live without that) now. Thanks a lot!

Sometimes I have to dirty flash "flash rom zip again over top of original flash" without wiping dalvik or anything to get signals to pick up and I'm current on Zvc , prl , ect. Never hurts anything and always seems to work if the traditional way doesn't, if you see this problem again might try.

[Q] Root + Custom Recovery for ZVC

I received the OTA ZVC update last week and was currently rooted and had TWRP installed at the time. I reflashed the stock rom using the LG Flash tool and went through three updates to eventually wind up at Kitkat, when I was using the stock ZVA rom I was able to use IORoot 25 to root my phone and then use FreeGee to install TWRP later on. Now that I'm on ZVC Official I can still use IORoot25 to root my phone but can not seem to get a custom recovery to stick, anybody else figure this out?

You need a downgraded aboot and kernel.

There's a new method to install twrp without breaking download mode , once you're on ZVC rooted with ioroot25, download the new app by @Cloudyfa http://forum.xda-developers.com/showthread.php?p=51857807 which would install twrp and you will still be able to use download mode if you have to!

Also, you can just flash the ZVC TOT. You don't need to flash an old TOT and work your way to current. I was on ZV7 rooted and went straight to ZVC TOT.

I just did what IORoot25 and the AutoRec. I'm with sprint and just got the phone. What can I do with this KK release? Can I install camera update or try out kernels? There seems to be no roms for this ZVC update.
So, I do I determine which kernel is patched to work with ZVC? since AutoRec is patched, there must be other patched Kernels out there. Just a noob right now.

KitKat just came out, developers are hard at work breaking things down so it is safe to flash. Lg did some things making it tougher and a lot of internal changes.
Kernel, only other available is furnace 2.0.

Does anyone know what to do once download mode is broken? I have progressed between the "stuck in recovery mode" problem, then the fastboot only problem, and now while getting download mode to actually show on screen instead of fastboot i have broken my download mode with fastboot-ing zvc files to the phone. Any ideas on getting this back in a programmable state? I'm on a windows 8.1 x64 machine.

Try the auto-rec for your model here on post 1,
http://forum.xda-developers.com/showthread.php?t=2715496
I'm on Sprint ls980, and no issues. This will fix boot, kernel, recovery, and download mode.
If you get white lines, us the fix @Cloudyfa has posted to get back. This puts you back to how it was before the program. No recovery and locked boot and stock kernel.

Flash Lollipop OTA file on stock LG G3

So my gf has a G3 d851 white version.
Was gonna do the lp update for her, but of course lg screwed up the mobile tool and it only works on the black version. Unbelievable...
The OTA file is out, but this is the first phone I've used that doesn't seem to have a normal stock recovery?
I can't just flash the update.zip 100% stock can I?
Do I have to have a custom recovery? And is root needed to install twrp?
So let's say I do have to root it, and install twrp... After I flash the update.zip in twrp will root be lost? And will the stock recovery be put back or would it still be twrp?
Reason I'm asking is, have to keep phone 100% stock. I've always done otas manually, just weird on this phone...
I have a G3 d851 too but I rooted mine and go crazy with roms.
So yeah how the hell do I go about flashing update.zip on stock?

1) you definitely need recovery
2) I don't know if you need root, but I'm sure you can find out if you read the stickies.
The OTA is gonna be out in a few days. Just way till then. ☺

my concern is the r update ota bricked me last time and i had to unbrick. hate to say it but ill wait till someone on here makes a flashable zip of it.

I skipped that whole.method and flashed via the kdz. Finished in under 10 minutes. Super easy and didn't have to root or use custom recovery.

I also did the lollipop kdz install and then rooted the phone with the new one click mod. Very fast and easy. Now running very smooth and without any problems

Help getting from ZVD to ZVG

First off.....I deal with Samsung devices and not very familiar with LG. Would like to get my wife's Sprint LG from ZVD to latest (assuming it is ZVG). I've spent some time reading forum posts and see plenty of "return G2 to stock" but it doesn't list what version of stock they are taking the device back too.
Assuming I have to get the bootloader and modem updated to lollipop, and use LG Flash Tool, what files do I need for this? Is there a stock 5.0.2 rom image somewhere?
Thanks.

If she is on zvd, and it is a Sprint phone on sprint network. It should automatically update. If it is not on sprint network, do not tot out go back to stock.
Use something like cloudy kit kat rom 2.2, or cm build. As you can set it up to work on the other network.(gsm)
Lollipop 5.0.2 there is no stock base on it. You would have to go to zve stock, then let it upgraded to zvg. Or sideload it.
There are too many changes to just flash a different ROM, and get to the latest.

Yes... It is a Sprint device on the Sprint network. The update has not been pushed yet and Sprint cannot help with getting it done. That is the issue. If there is no 5.0 base then there is no way to upgrade it manually then? Seems odd to me but guess it is what it is. Would think someone could pull the OTA from the device and upload so a base could be made.

Agimax made a stock based rom called ultra pop. But just going straight to it bricks. Firmware and partitions change, radio, and software.
Even going from his slimmed down version to stock messes up. I tried that going to cloudy 3.3.
You can stock to zve, and push the upgrade to zvg. There are the zvg upgrade zips sitting out here. But you can't just go to it I hear.
You also have to remember lollipop is on a different cache. The older versions were davlik and lollipop runs on art.
2 completely different things.

Need help getting V410 LTE on stock 5.1.1 with OTA updates

Hi. I have an AT&T LG Gpad 7 that I downgraded to 4.4 to root using a thread from XDA and then tried out Candyrom and CM12 and CM13.
I need to return this device to stock condition.
I followed another thread contained within XDA but no matter what I do, I cannot use OTA to get back to stock lollipop.
Here is what I did:
Installed stock test KDZ using LG Flash Tool2014
Rooted via one click
Fixed partition size
Installed flashily
Installed TWRP via flashily
Installed stock 4.4 rooted rom from XDA
Flashed stock recovery from XDA
When I did this. I still have the white line distortion and OTA updates do not work. Any ideas? I wish I could just get the real KDZ for the AT&T V410 LTE 16gb!

I'd like to be able to get to Stock 5.1.1 as well. I'm at the same spot you are. Except I didn't do the stock test, I'm on 4.4 rooted.

，I also was told I could not return to a 5.1. But I just want to try or cm12 cm13. Can you give me some help?
