To answer your question no I have not installed the full OTA update just the modem. How did you do it? Did you make a flashable zip?

I did have a problem receiving SMS but only after I had flashed the US998 20E kdz. Since then though I have been trying to recreate the issue so I have been going back and forth between my backups of the stock Sprint and almost stock 20E. Only thing changed is the modem. I am actually about to start the entire process over by going back to Nougat and trying to get the 20E with latest Sprint modem to work properly for me.

On another note though I tried dirty flashing a backup of 20E over the Sprint 21A and data came up with no issues. This is probably not a good way to go about it though.....
[LG V30 Guides, News, & Discussion] alecthenice:
I installed the whole update. I will go back into twrp and flash just the modem with my rom, magisk no root check and no encrypt and see what happens!

[MENTION=1488317]boxchevy[/MENTION] , I am using LS99820a I think (even though I use the 20b patch in OP< it still says US99820a in about phone)....What is step to just update the modem?

Everytime I tried to use 21a I could not debloat, as the apps just came back
[LG V30 Guides, News, & Discussion] boxchevy:
The modem zip that was uploaded a few posts back you will need to extract and change to modem.bin and use the dd commands at the beginning of this thread OR change to modem.img and flash via TWRP using the install image option and placing it in the modem section.

To debloat I use Titanium Backup Pro.
[LG V30 Guides, News, & Discussion] Ainz_Ooal_Gown:
You have to let all the Sprint/Partners bloat install completely then uninstall all of them...
[LG V30 Guides, News, & Discussion] amicold:
In regards to your texting issue. I am not confident but it sounds to me like a network issue. Issues with voice reception due to travel or a message queueing issue. I believe CDMA has a distinct way of queueing SMS but I haven't refreshed myself on the technology in awhile.
[LG V30 Guides, News, & Discussion] :
Where is the "Modem Section"?

I use TIBU as well, but when using 21a most I deleted just came back.

---------- Post added at 09:27 AM ---------- Previous post was at 09:25 AM ----------

Are you saying that I just tried to delete stuff too soon? For example, I couldnt even get the stock Clock app to delete in 21a, but all good in 20b
[LG V30 Guides, News, & Discussion] boxchevy:
Where is the "Modem Section"?

When you go to TWRP and choose install you need to change it from install from zip to install from img. You will see the partitions where one is the modem.
[LG V30 Guides, News, & Discussion] :
Did you have to reflash Magisk, verity etc after?
[LG V30 Guides, News, & Discussion] boxchevy:
No, if you are just flashing the modem.
[LG V30 Guides, News, & Discussion] :
I did this, but the baseband is the same as before? How do we know this is a different modem?
[LG V30 Guides, News, & Discussion] boxchevy:
It should change AFAIK. I cant check right now as I'm on the road. I switched back to my backup for the trip. I do know though if you compare the file sizes of the modems from the 21A and the recent OTA the sizes are different.
[LG V30 Guides, News, & Discussion] :
modem is baseband right?
[LG V30 Guides, News, & Discussion] boxchevy:
Yes
[LG V30 Guides, News, & Discussion] :
its def the exact same.....maybe they didnt change it
[LG V30 Guides, News, & Discussion] Ainz_Ooal_Gown:
Wait your trying to delete system apps not the Sprint bloat?
[LG V30 Guides, News, & Discussion] boxchevy:
How did you verify that? I was thinking you could flash the 20E modem, verify it changed, and then reflash 21A to confirm. I believe that is what I did. I took some screenshots but I transferred to my PC to see it as I was making changes. This is what I have right now but it is not how I was trying to have it so I'm not sure if I reflashed the modem in the OTA.
[LG V30 Guides, News, & Discussion] :
Yes, system apps......21a is odd, many were having issues....not just Sprint bloat

---------- Post added at 12:12 PM ---------- Previous post was at 12:12 PM ----------

I took a screenshot of baseband before and after. Flashed 21a again...then your modem you uploaded above
[LG V30 Guides, News, & Discussion] boxchevy:
And your baseband shows the same as mine in the screenshot?
[LG V30 Guides, News, & Discussion] boxchevy:
I believe what I posted in the screenshot is 21A. I redid my phone yesterday as I was troubleshooting. I know I changed it because I flashed 10D Nougat to start over, then 20D Oreo, then 20E Oreo.

I took screenshots of each baseband to verify it was changing. I ran into an issue where 20E would not boot after flashing the extra files to remove encryption and all that.

So I then restored my Sprint 21A backup and then flashed 21A. Why? Because I lose the Update PRL option in settings whenever I restore this backup. Not sure why. But dirty flashing allows me to keep the data and get the option back.

That is why I said I'm not sure if I reflashed the modem from the OTA as I was finishing my vacation and needed phone.

If yours does not change at all then something is weird there as it should say something different whether it is one number difference or a few.

---------- Post added at 06:39 PM ---------- Previous post was at 06:22 PM ----------

If yours looks like the screenshot posted by travy towards the beginning of this thread then I may have flashed the OTA modem after I restored and all that.
[LG V30 Guides, News, & Discussion] :
Perhaps that modem you uploaded above to this thread wasn't the new one?
[LG V30 Guides, News, & Discussion] boxchevy:
I actually didnt upload it but it is the same size as the one I got. I actually just got home so in a bit I'll be checking it and posting back.

[MENTION=2358282]islandfever[/MENTION] My mistake. You are correct. The modem/baseband stays the same as far as the version. The file sizes are different. On my screenshot it is actually the US998 Oreo modem/baseband. As I stated before I have been troubleshooting the device and backing up and restoring roms.
[LG V30 Guides, News, & Discussion] :
Thats what I thought.

Have you tried any ROMs that actually play well with Sprint?
[LG V30 Guides, News, & Discussion] boxchevy:
The only ones I have had success with is of course stock Sprint, stock US998, AOSP, and AOSiP. The others I would have some kind of issue ex: no LTE or won't boot. I got LTE on one of the others but it was very slow like 2 Mbps download where I easily would get at least 15 Mbps.
[LG V30 Guides, News, & Discussion] :
What rom was AOSP, AOSiP......what are you thinking is best?

[LG V30 Guides, News, & Discussion] boxchevy:
20E is the latest US998 kdz. It has September's security patch.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, for you who converted H931 to US998. That's what Frankenstein was created for -- to carrier unlock H931 and LS998 by flashing to carrier unlocked variants, like US998, AS998, Canadian H933. Later we incorporated Frankenstein into the WTF for bootloader unlock and root, because US998 has the necessary fastboot flash commands NONE of the other North America variants have.

But doesn't apply to people in this thread. This is a Sprint thread where many convert BACK to Sprint LS998 after bootloader unlock and root with US998. Some are carrier locking back, while keeping TWRP and root

Any more questions about converting to

US998 let's carry back over to Frankenstein thread

. ;) I was merely using your post as most recent example H931 can be rooted with WTF. He posted in wrong thread to begin with, and I don't want to keep doing that. ;)

What steps would I do to move from 21a to this KDZ?

---------- Post added at 10:35 AM ---------- Previous post was at 10:32 AM ----------

Is it smart to remove these ATT posts, so as to not confuse Sprint users, as it is not a simple process as we have all seen! =)
[LG V30 Guides, News, & Discussion] ChazzMatt:
Where are you seeing 21a? Yes, A 21a for the SAME variant would be newer than 20e. But make sure you are talking about the same variant.

Europe H930 has 21A, but do you see 21a for Sprint LS998 somewhere? I KNOW US9998 is still on 20E; 20E is the newest for US998 with September patch. Canadian H933 is on 20G. So, I want to make sure you are not comparing European firmware number with North American firmware numbers.

Different variants have different firmware numbers, but are still the same "stage" of development. 21A for Europe H930 is NOT more advanced than 20E for US998.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You did good by booting to TWRP first before booting to OS. At this point (in TWRP) is where you could have also flashed Sprint modem, before rebooting to OS.

You would still have to edit/change APNs after rebooting, but would already have Sprint modem.

At least that's my opinion, unless someone had real life experience different...

So I recently flashed my Sprint V30+ to 20e through using the KDZ file. I got LTE and everything working, but I have a question. Would I have lower data speeds and less service on a US998 Rom than a Stock LS998 rom? I tried testing both speeds but I can't flash back to stock Sprint ROM, as it corrupts my system partition.
[LG V30 Guides, News, & Discussion] boxchevy:
I had previously been getting slower data speeds using a non-stock Sprint rom. Currently though it seems to be about the same as stock. I am using the 20E with the Sprint modem.
[LG V30 Guides, News, & Discussion] djpabz23:
Did you update PRL on the Sprint ROM before flashing 20e?
[LG V30 Guides, News, & Discussion] djpabz23:
One last question. Do you sometimes not get any SMS? I have this problem where I sometimes do not get any text messages. After I send one, I get bombarded with all the messages that I had not received. I added the Sprint APN correctly, I believe. Now, I am unable to add or edit any APN's as it is all grayed out.
[LG V30 Guides, News, & Discussion] boxchevy:
I did see that problem at one point but I was traveling at the time. I haven't seen since I have been back. I started using DotOS yesterday to see how it is. It is working so far.
[LG V30 Guides, News, & Discussion] lilila:
Had this exact SMS problem too. Has to go to Sprint ROM to fix it. Anything else I tried was useless.

Just find out after flashing Sprint modem, followed by editing APN to get 4G LTE and SMS working on US998 or VS996 ROM, the phone is carrier locked again. To use a sim card of a different carrier, I have to go through the KDZ to 10d, 20a process again.
[LG V30 Guides, News, & Discussion] djpabz23:
Thanks for the clarification. I switched back to Stock and all is working perfectly fine.

[LG V30 Guides, News, & Discussion] Ainz_Ooal_Gown:
So where are we on getting that OTA as flashable?
[LG V30 Guides, News, & Discussion] lilila:
It seems in order to sim-unlock again, you only need to flash a compatible VS996 or US998 modem.

[LG V30 Guides, News, & Discussion] jdgesmlls:
Can anyone provide any insight as to how you can re-lock the bootloader after flashing the FACTORYSPRINT.zip? I realize it removes the bootloader unlock warning but OEM unlocking still remains in developer options.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Your best bet is probably just to convert to US998, relock bootloader and sell on eBay as US998. Trying to flash back to full stock LS998 with locked bootloader is probably not possible for the tools we have on hand. (May need an Octopus box or something.) Lots of Frankensteined LS998 > US998 are being sold on eBay. With all due respect for you (you're mentioned in my WTF instructions as a contributor) your problem is trying to use Swappa to sell it, not the phone itself. ;) Which, if I remember correctly, you bought it on eBay, right? :D

Former AT&T H931 would have the same "problem", which is not really a problem. They can also sell the phone as US998 on eBay.
[LG V30 Guides, News, & Discussion] jDally987:
Bump for interest, I'm also wondering this, I'm in the exact same situation. I've already flashed my H931 to US998, and at ChazzMatt's indication actually, I think I'm going to go ahead and flash LS998 and just stick the already-activated SIM from my Essential phone in, and see what happens. Would appreciate if anyone has any tips before I set it on fire or something though.

EDIT: for anyone trying to do this, don't bother. DID NOT work. Updating the PRL/Profile results in an "authentication error" and it refused to register on Sprint's network. I got in their live chat to see if I could schmooze them, but as soon as I gave them my IMEI they said the phone was incompatible for BYOD.

I think I'll just buy an LS998 and sell the current one as a US998, but at this point, I'm seriously thinking about switching off Sprint entirely, even with the FREE (!!) year of service. It's honestly giving me such a headache that I'd rather just pay a few extra bucks a month for a quality MVNO on another carrier.
[LG V30 Guides, News, & Discussion] Ainz_Ooal_Gown:
Well yeah...you must activate the LS998 before attempting to turn it to a US998 or else no activating on Sprint...but you started with a non Sprint model...
[LG V30 Guides, News, & Discussion] jDally987:

[LG V30 Guides, News, & Discussion] ChazzMatt:
Sprint does not release stock KDZ.

Some people have flashed raw_ resources, raw_resources_bak partitions from another model like Verizon vs996 via dev patche LGUP to get rid of the bootloader unlocked warning. If you did that successfully, your bootloader would still be unlocked, but not show the warning.

That is totally up to you and you take all risk. One person bricked their phone trying to do that, while others did it fine.

If you did brick your phone, would Sprint take it back then? ;)

Oh and to clarify I'm not knocking your setup, I'm legit curious.

**Edit: Ok so after checking out my own PDNs I noticed some differences besides the additional APN types. I am curious if you or anyone else can shed some light on why we would have different settings in some areas that seem like they would have to be set to the same thing if both of our phones were working fully.

[LG V30 Guides, News, & Discussion] ChazzMatt:
If you used this method from the op (post #1), I'm pretty sure you are SIM card locked again to Sprint. However, you are still bootloader unlocked and you still have TWRP custom recovery. So, you can simply flash the

JohnFawkes made to convert to US998.

It's like Frankenstein but without all the hassle. ;) After flashing, just flash Magisk for root again. It's like flashing a ROM, but you are converting your phone to another model. JohnFawkes also made the Sprint TWRP-flashable file, mentioned just above your post. (Not officially "mentioning" him with the @ sign because he asked me not to do it so often.)
