[G2 Q&A, Help & Troubleshooting] 2strokenut:
I figured with the amount of bricked LS980s with Justins rom I've been seeing at my shop I might as well make some sort of tutorial to help some people out. Searching doesn't bring up too many threads but there are a couple and hopefully a few of the guys in those chime in. My goal is to make this visible and save many of you hours of trouble. Many thanks to Justinswidebody for building the rom. I won't post the link as most can use the search to find it just fine.

Why does the LS980 brick with Justins rom?

It updates.

I think the majority of people flash the rom and forget to take the necessary steps to prevent an update and when it does it will try to reboot into recovery and wipe the system resulting in a soft brick. Most of the time TWRP will remain, which is good, but reflashing the rom will do no good.

Right after this happens what do I do?

Imeadiately plug in you usb and adb push the stock ZVA rom onto the sdcard

use this command:

adb push nameoffile.zip /sdcard

It will take a while.

Once it finishes you need to wipe everything but internal and flash. Once done, power off and boot into download mode.

Prepare LG Flasher and correct TOT file with DLL. I may post a link later.

In my personal experience with installing justins rom it's best to start fresh with ZV7, trust me you will have less headaches. Once it finishes you're ready to redo the whole thing.

I dicked around with the phone and now I can't get into recovery?!

You have to have recovery on there.

If you can't get into download mode then your journey ends here, not sure there is a fix for that, however, you probably already have it in DL mode and getting a fail "wrong DLL" or some ****. Your phone now thinks it's a T-mobile D801. Forget the sprint files, you're gonna flash the tmobile files just to get it to boot. I actually had a customer bring me the phone and managed to flash the right combo to get it to boot but he didn't know what he did, I'll have to find them.

Now, once booted up you'll notice wifi and data will not work along with keyboard and other things thus making it impossible to download flashify and reflash recovery. The phone, in some cases, will only stay booted for 20 seconds and then reboot over and over. It's like this phone is actively tying to make your life difficult. Relax, and let the adb drivers install. Test it by opening a command prompt and write: cd/

/adb

/adb devices

Allow the rsa key. You won't have time to transfer the stock sprint ota file so we need to transfer it in recovery.

Download the simpletool flasher by OptimusRS, this will flash recovery to your phone and remember to choose d801 not ls980. Reboot into recovery. Once the adb drivers have installed you're going to adb push the stock zip back onto the sdcard like you did before. Wipe everything and flash, then power off. Once you boot into download mode it should recognize the phone as an LS980 once again and you are free to flash the correct tot and dll files.

Congrats! You did it!

How do I prevent this from happening in the future?

I've been fighting with this for a while and I think finally know how to be 100% successful in turning off the OTA, if anyone has something to add please do

Go into the app manager and find google services framework and uncheck or disable or both

Use a file manager to go up to CACHE and delete the update that will most likely be hiding in there

Go up to system/app and rename any service that looks like it would provide an update- LDdownload provider is one. I wish I had a list of all of them but I really don't know what the exact app is.

Special thanks to all the guys contributing in these threads:
