[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Team DevDigitel:
be ready to fix a error code 16 or the no calling issue.

i think i may have pissed some other devs off by pointing out the ptn/msid failure was related to aosp builds

I tried both Aokp and lineage. I didnt have issues with AOKP casuing my ptn or msid to get cleared or the error code 16, but the build i tried was semi-wonky still for ls997. I may have made a install error but it wasn't showing service, but the phone was def. active. When making a call it would show service and work, but once off the bars went away but service was sill there. Just a visual error. The rest was fine. No 2nd screen of course and dont ask the devs to fix as its being worked on but isnt just adding the app back so it will be some time before it works. Of course no wifi calling, and no prl or profile updates on aosp roms.

There was issues with my sd card showing up currupt after a flash, so maybe use a clean card to be safe? I just used windows to fix the secotors and deleted a folder that was placed on card by system i guess. it was named found000 in the root of my sd. When i restored my backup it was giving me fork error etc saying backup was bad. I just restored it anyways and then dirty flashed rom overtop and it worked fine.

The lineage rom caused more issues, but the rom itself was better as far as bugs, and the service stuff. When i tested lineage and tried to restore back, once back on stock i had the dreaded no service for calls or text but had lte. When i did the trick to fix the "unknown" ptn and msid my 1st call instantly got me kicked off the network and the error code 16 came up. I had to speak to sprint by just waiting for the prompt after the error code 16 and giving them my account info and they refreshed my device and unblocked my account. It required a reboot and a prl&profile update to fully return my service, get me 100% back on sprint and 0 calling or texting errors.

I dont think its the devs fault on lineage, i think its issue with sprint and tower security and the rom being able to use any service etc. The bug more then likely was from me playing with the network settings while on lineage that changed my NV items to something else. The NV files are where your activation stuff gets saved and the info for the PRL and the ESN are saved. Typically this never gets adjusted after you activate and I believe adjusting it while on the network is whats causing the error code 16/no service for calls text.

I tried to explain the information i had gotten from my experience to the dev thats running the roms. Both seemed to take offense by me posting the information and not being more specific and adding photos and logs. I was just testing for this reason exactly, so i knew what to expect for users when they go from another rom back to mine etc. And tracking down some of the bugs you guys have posted here and created other threads for.

In a nut shell, test it when you have some extra free time and using your phone isnt critical "not during the middle of your work day" lol

I'll probably fully test them more this weekend once im off work, as well as i left my info for the other devs if they wished to have me test and help manage

the issues with LS997 users atleast. We will see where it goes. I'm just trying to make sure atleast the sprint users with the LS997 have atleast 1 solid person willing to help and troubbleshoot. The other 50 models should be trying to do the same thing.

hence the reason my thread supplies a section for other mods ive tested and things that will work for us. A LS997 one stop page. At some point ill add the aosp builds into the list so we have a easy place to locate the threads as the forum grows more and more with newer posts and other fluff that push the important stuff down further into the abyss, another good reason to make sure to post here often to keep the rom page near the top of things =)

hope this helps get you started, and by all means id def try ALL the roms out that are compatible with out variant, this is half the fun and each time we test things we can clear up issues and help get our devices 100%, as well these other devs are doing the custom work and the extremely time consuming stuff, the deserve attention as well as thanks alike. I wish the dev communication was better as they have all seemed to fix the driver issues on our variant but haven't really supported a "HOW TO" on building the kernel and what part was the root cause of the static in the 1st place. Without someone else on my team helping me my work is going to be a ton slower and take a LOT more time testing and fixing things.

I've started posting all my work on GitHub especially for the build from source and my recovery project and the kernel project as well. In hopes that the ls997 devs out there will be willing to start working on putting together a complete stock-ish boot.img from source that has the missing debug stuff that resolves static.

We will get there eventually..
