Hey guys, I haven't been able to make this work, but reportedly it can be done. How can I get CyanogenMod on the LS980ZVA radio?
Part 2: after I do that can I use a TWRP backup to go back to stock? I ultimately want to be able to switch back and forth. Thanks in advance.
Only kernel that supported ZVA radio on cm11 was Furnace but it was a few versions ago. I think v2.0.
Okay. If I flash Furnace can I then switch back and forth via Nandroid backup?

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.
I'm on CM11. I'd like to return to a stock-like JB rom for the time being until there's some reasonable functionality available in the AOSP-based KK roms. I've seen the warnings on the int'l forum that once you go to the Sammy 4.4 roms, you can't go back to JB due to the bootloader update. I've not installed a KK rom other than CM.
Does this no-going-back issue apply if I've only done the following?
1) Rooted stock MI7 using RDLV, installed TWRP Manager
2) Flashed TWRP recovery
3) Wiped device, flashed CM11 nightly build
I looked through the forums but I've not found this question or answer, so I apologize if I'm reposting... I guess I just didn't find the magic keyword combo to search for.
You can still go back to 4.3. Did you happen to make a nandroid backup before installing CM11?
Cm 11 isn't the same 4.4 as the official tw 4.4 which is the one with the updated bootloader. So going back to a 4.3 rom is not a problem. Either find and flash the stock rom located in Dev section or you can Odin the stock tar file (which will revert you back completely to stock.

I'm stuck in a similar spot.
On TMO 4.3 stock/deoxed, I did a nandroid backup with CWM 6.0.4.6, flashed CM11 to play with a for a few days, and after restoring the backup, the phone boots, but after putting in my pin, all i get is black screen and lots of force closes. I tried the Brick_Loop_fixer zip with no luck. I've different combo of wiping cache/davik cache and formatting system BEFORE the restore with no luck. I also tried ODIN back to full stock, flashing the stock/deoxed ROM i was using, then doing the restore, same outcome.
Any help would be great!

I want to try out Grola rom but i really dont want to go through the process of having to .tot just to go from that rom to another. Is there a way to flash another rom without having to .tot back to factory.? I have the ls980 variant

Read the directions very carefully. If it is aosp or cm variant. You need to flash the zv8 radio after the ROM.
Primary thing, make a backup first. If you have newest TWRP, it will backup radio. So when you recover you can have no issues.
If it is stock based no problem. You only have to tot if you really needed something up or going back to zvd or zve radio.
Ok so i just boot into recovery, flash correct radio and flash the new rom i want. Unless its a zvd or zve stock based rom then i would have to .tot right.?
Right now I'm on resurrection remix. Which is cm based. So I have already downgraded boot loader by getting TWRP installed. I flashed zv8 radio for the ROM. If I wanted to go back to stock based because I didn't backup my radio. I would tot.
This way my radio is back to what it needs to be.
Or if I screw something up on flashing I can tot.
I flashed a 20b ROM but now want to go back to kitkat so I can use my unlimited wifi tethering.
The ROM thread says to flash the 10r bootstrap before restoring to my saved kitkat nandroid, but when I do and then reboot it, I have no Data.
Im pretty sure I am still using the 20b modem. What do I need to flash to restore back to kitkat?

If you didn't backup your efs then you're stuck on lollipop ?
Any update or changes to this? I use an app at work that does not work on Lollipop at all.
I NEED Kitkat...
Give this method a try...

Other than having your phone replaced, this is the only method I know of that actually works for restoring LTE after a downgrade. Here's a link to the original thread...

Fellas,
I just rooted my phone and learned from a youtube video about creating nandroid backup. I am really excited by this custom ROMs. I want to install lollipop on my Galaxy s3. I see that all the builds on the download section are nightlies for 12.1, so I am not sure whether I can go ahead and install one. I am concerned about any potential issues as I use my phone to get work emails. Can I grab the latest nightly and go ahead with flashing? Also, can you list any issues that I need to be aware of?
Have you updated your phone to the latest stock ROM? If not, I suggest you update to the latest stock ROM, then use Odin to install a custom recovery, use the custom recovery to create a nandroid backip, and finally use custom recovery to flash a custom ROM.
