Ah, I overlooked the part that you were already bootloader unlocked. Sorry I really glossed over that part. :( I read "I want to convert an LS998_30a...Frankenstein and WTF to US998 20h."

So, you have already done the hard part and do not need to go back to Nougat. You are already bootloader unlocked and on JohnFawkes Sprint TWRP-flashable zip (ROM). To "convert" to US998 all you need to do is TWRP flash to JohnFawke's US998 20h TWRP-flashable zip as if it's a custom ROM and then reflash Magisk.

You will have the US998 modem and frequencies.

The Sprint questions I do not know about since they are now T-Mobile. I know with the older T-Mobile SIMs everything was fantastic with US998. And towards the END of Sprint -- before they became T-Mobile -- they started accepting the US998 phones. So, the answer is possibly yes -- if you still have the Sprint SIM card? But honestly I don't know.

RCS is Google's answer to iMessage, kinda. It's the eventual replacement for SMS/MMS. It let's you send photos and videos up to 105 megabytes and see typing indicator and read receipt right in the message app.

I'm using Google messages, I think that's the only app that supports it right now. Go into settings of Google messages then under advanced, you should get a blue screen asking to activate it (if your service supports it, Sprint does)

HELP!!! Failed to mount "/data" (device or resource busy"

Long story short: Was currently on the Stock (Joan) Spring LS998 26A firmware. Everything was working beautifully for several days until I decided to "test" another Rom out , the Havoc-OS 2.1 rom. Since attempting to flash it I am stuck in TWRP 3.2.3.7 and can't restore backups, wipe anything, etc. The internal system is showing 0 MB. Clearly I did something wrong (possibly on the wrong recovery to flash a AOSP?). I attempted to power off from TWRP but it booted right back into TWRP.

How do I get out of this jam? Embarrassingly, I have been rooting and flashing roms for years now without any MAJOR issues.

Any help would be GREATLY appreciated.

Thanks in advance
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] fitwright:
Fixed my problem...phew!!!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Lurien:
Has anyone else dirty flashed this coming from 21A?? Any issues? Thanks..
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
No issues here
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] whYME953:
Is the original KDZ for this available anywhere? I'd really like to be able to do this with LGUP and avoid the whole rooting/unlocking etc...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
No. Sprint doesn't release KDZ, nor does AT&T. They only do OTA updates.

Are you a Sprint customer? If you're a Sprint customer, that's the only reason you need Sprint updates and you'll get it with OTA. You don't need this ROM.

If you're NOT a Sprint customer, then convert it to US998 and use LGUP to get updates. Why are you keeping it LS998, if you're not a Sprint customer?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] whYME953:
Thank you for responding.

Basically I am a Sprint customer, and I bought an unlocked LS998 (I'm too new here to post outside links, it's this phone: bhphotovideo-DOT-com/c/product/1445075-REG/lg_lg_ls998blk_v30_ls998_128gb_cdma_gsm.html) which I just cannot seem to be able to activate on Sprint. When I tried it worked for a few minutes then I got an error, something along the lines of "could not connect to carrier. Sim card has been locked."

Everyone I speak to at Sprint tells me the same thing, that I need to go to settings > general > system update and update the profile. the problem is my phone does not have this "system update" menu option. (originally I tried with a US998 but had the same issue, I thought maybe if I returned that and tried with the LS998 that's supposed to be a Sprint variant it might work) So that's what brought me here, I thought maybe if I could force the update I might be able to get it to work...

I upgraded to US99820f but that doesn't seem to have made any difference.

So I guess the real question is if there's anything I can do here to get this phone working or do I just need to forget it and return it?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
When you bought it, did the firmware say LS998 (not the box, but the phone itself) or was it flashed to US998 firmware? Some dealers claim it's an "unlocked" LS998 but it's really an LS998 carrier unlocked because it's been flashed to US998 firmware. THAT is how it is carrier unlocked. I'm just asking. I know that's how they sell it at Wal-mart.

But you need it to be LS998 to activate it on Sprint.

You can always bootloader unlock, install TWRP and flash to this Sprint "ROM". Then activate it? Maybe [MENTION=6815443]JohnFawkes[/MENTION] can give you more information.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] whYME953:
That's a good question. The box definitely says LS, but I think the firmware may have been US. Does the fact that I was able to upgrade to US99820f with LGUP (following this: https://xdaforums.com/lg-v30/how-to/guide-how-to-upgrade-downgrade-restore-t3738917) mean that it was already a US998?

FWIW when I went to "check for updates" it said no updates available. Should it have shown the available US998 updates?

My problem with this was that I didn't want any issues in case it doesn't work and I want to return it.

Because [MENTION=6815443]JohnFawkes[/MENTION] said that this was made from the original KDZ I figured there may be copies of if it floating around, even if it hasn't been officially released by sprint.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Lurien:
Dirty flash?? Thanks..
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
the ls998 zips arent made from the kdz. that was my fault. i shouldnt of copy and pasted my OP from us998. sprint does not allow access to the kdzs. they dont release them. what i did to make it was take the 26a ota update then pull the needed partitions with dd and create the zip. took forever. if i get time ill create a factory zip and release. basically one that will un root and go back to fully stock
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] sclarktay4:
First off, thank you for this. I have been running this for about a week now. i have noticed that my data (LTE) disconnects randomly. I did the dialer code in the instructions and updated the prl as well. Is there something you can suggest I do to fix the random data disconnect? I have a sprint tablet as well and it does not have this issue so I would assume it is what I did to the phone.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
no clue. i havent had this issue

Incoming Call Mic Issue

When answering an incoming call from a verizon caller, my mic does not work when Volte is enabled. I can hear them perfectly, but they cannot hear me. I have to hang up and call them back and it works (with volte enabled still). If i turn of Volte, everything works fine, but the earpiece volume is too low.

Anyone else experiencing the same?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JONBOY345:
Might be a dumb question, but this ROM is for the Sprint variant, not the VZW one, maybe that's the issue?

Woo! I could not get my US998 to connect to Sprint. Flashed with this and now I'm back in business.

Successfully dirty flashed 27A over 21A.

My process was to follow the OP

1) Fastboot to recovery (used 1 revision back, i think 3.2.6 instead of 7)

2) Backed up

3) installed 27a zip

4) rebooted

5) fastboot back to recovery

6) Installed Magisk 18.1

7) Ran Magisk

8) Successfully used titanium backup to remove apps I hate

Thanks for the quick reply. Actually I tried that first. At that point it was just the message and I had very good service. Should have left well enough alone. Instead, I let the sprint chat service reset the network. Now I lost service. It seems the phone isn't activated. Can I go through the normal activation process from US998 27a or do I need to be on an LS build? This is the first time I've been on an unlocked phone so I'm still processing all the logic involved.

The step I always forget is ##SCRTN#. This will reprovision your network to Sprint and should get you back to full network access. I'm sure there are other steps you could take, but this has worked for me every time.

I keep trying out other ROMs, and I keep needing to go back to stock. You would think I would have figured this out by now.

I'm currently using the LS998 converted to US998.

I'm going to test out a Sprint MVNO (they offer ATT as well) temporarily and if they do a great job I'll switch from ATT since I'd be getting basically the same service for less and only be losing free unlimited international texting which I don't ever use because people in other countries say it's too expensive to text me and they always want to use some kind of app. ATT support is outsourced and/or garbage like the rest of the big guys and I may have found a company that actually stands out from the MVNO competition enough to swap from ATT.

Anyways, I want to get back my Sprint bands. Would I just need to put the phone into bootloader mode and fastboot flash the radio image?

If this is fine, is there any other step (outside of things like APN/provisioning codes/other things to do once the phone boots) that I need to do?

Not yet. Seems lg has done something to kdzs. Not sure if it's the format/headers or not yet. Anyway I made a us998 zip and accidentally included the persdata.img from us998 and I couldn't get back to ls998 because of it. But the system.img keeps getting corrupted when I flash the new us99820h zip i made and users are having the same experience with vs99620j i made as well. Ls998 won't have this issue though because im not making the zip from the kdz. I'm factory reseting my device with a back to factory stock zip i made and I'm losing twrp and root. Then I have to take the Ota and then pull the partitions off my device and make a zip then convert to us998 to get fastboot and flash twrp then I can flash the zip i made and then I can root. It's a pain but worth it
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
Yea i was working on a Magisk module that would replace sprint files in us998 rom but it got way too big in file size and it was way too complicated. Basically my goal was to turn the us998 rom into a sprint rom. Have wifi calling, lte and VoLTE and visual voicemail. I was able to get lte but I really wanted VoWifi and VoLTE and I just gave up. Maybe I'll return to the project one day
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
All those things are important to me too. The exception is Sprint visual voice mail. When I was going back and forth between AOSP and stock on the V20 I decided to start using Google voice as my main voice mail. It's easy enough to do. Sprint offers free unlimited conditional call forwarding. This way I only lose the voicemails I delete rather than all of them every time I flash a new ROM. And it's practically the same thing in the end.
