ok phone is back to ls998 !!! but bootloader is still unlocked. how can i lock it without fastboot commands? right now its not showing the bootloader unlock yellow ! its just flashes a black screen when it should (same thing happens when i was running under a vs998 kdz)

EDIT UPDATE

if i put it in download mode. then load up LGUP it still sees it as US998. so im guessing that everything but the bootloader is LS998 and its just booting of the US998 bootloader. :/ the company i bought it from on ebay mass sells used phones. being that there is no fastboot commands for ls998 phones there probably is not a way for them to see that its running a different bootloader and that bootloader is unlocked. i guess its the best i can do. just have to cross my fingers for when they get it that they dont give me a hard time.
[LG V30 Guides, News, & Discussion] CreamyGoodness:
So I'm a bit confused. After following these instructions, I have my LTE bands back and am running LS998, but now apps like Titanium Backup cannot get root access. Can I now do a factory reset, then flash US998 and retain my Sprint LTE bands? Or am i just screwed with either bloatware + my LTE bands, or no bloat but no LTE?
[LG V30 Guides, News, & Discussion] ChazzMatt:
That's silly talk.

Sounds like you need to flash Magisk again or something.

OR

There's a

thread I started about Titanium Backup not getting root and how I fixed it.

When I get home I'll find it if you don't first.

EDIT: LINKED THE THREAD HERE ALSO.
[LG V30 Guides, News, & Discussion] CreamyGoodness:
Thankfully you were correct. I wiped my data, formated, then did the full installation process over again. This time root access was granted. Go figure
[LG V30 Guides, News, & Discussion] manic4droid:
Hi - did you try, And have any success with this? .... thanks; I want to try if good. :)
[LG V30 Guides, News, & Discussion] ChazzMatt:
Glad you fixed the problem. Here's the thread I was talking about. See page 2 for the solution.

Titanium Backup + Magisk?

Hey [MENTION=2732656]JWnSC[/MENTION], any chance you'll be able to make a TWRP-flashable zip of LS99822a?

https://www.androidinfotech.com/2018/08/lg-v30-sprint-usa-ls998-august-2018-ota.html
[LG V30 Guides, News, & Discussion] alphafuzzybunny:
First off, I want to thank everyone who is offering support for this phone. Special thanks to [MENTION=2732656]JWnSC[/MENTION] and [MENTION=3250376]ChazzMatt[/MENTION].

I have not purchased this phone yet, but plan on buying it once I know I can get version and security updates. It looks like Sprint users are relying on [MENTION=2732656]JWnSC[/MENTION] to provide security updates (especially when new US998 KDZ files from [MENTION=3250376]ChazzMatt[/MENTION] are not available). Like [MENTION=4710407]txag2011[/MENTION] and [MENTION=4313202]JesseAaronSafir[/MENTION], I would be very interested in the steps required to extract the security updates and make them TWRP flashable. I can program, but have no experience with Java or Android development, so a moderately detailed guide would be ideal. An update guide would allow the community to continue getting support in the case that [MENTION=2732656]JWnSC[/MENTION] or [MENTION=3250376]ChazzMatt[/MENTION] got new phones or got busy and didn't have the time to create updates.

Like many here, I keep my phones for years and rely heavily on the community for updates. My current phone is an HTC EVO 4G LTE that is working just fine after 6 years, but I am finding that many apps do not support Android 4.3 any longer so it is time to get a new phone.

Also, [MENTION=3250376]ChazzMatt[/MENTION] might be doing too good a job of telling people how great this phone is, the prices for the mint LG V30+ on ebay went up from $310 to $360 the other day.
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
Yeah I got my Sprint LG V30+ LS998 on eBay in 9/10 like new condition for $229, I think. Great price for a great phone! I'm surprised that since we started being able to unlock the bootloaders on most variants in May (right?), we've still seen hardly any development happening for this device. I'm pretty happy with stock rooted LS99821a as I have Xposed and ViPER4Android and TWRP and TitaniumBackup all working and I LOVE the "G7 Black Theme for LG V30 and G6 Oreo" from WSTeams! I'd like to get 3Minit battery on here and maybe 3Minit clock but the clock mods available from GravityBox [O] are pretty close. I'd also LOVE if I could have the Dual Statusbar that [MENTION=4904853]carlosggb[/MENTION] baked into his ROM for Note 4. Actually DtuxRom [MENTION=4904853]carlosggb[/MENTION]) has a ton of options and I'd love to see more of those available for this device as well. Beyond that I'm sure there are plenty of opportunities for development on features specific to the LG V30+ or to LG's implementation of Android. I'm hoping that as more people grab these "like new" V30's from eBay we'll see the development pick up.

If there were a reliable way to flash the Sprint modem and ensure that you're getting all the Sprint LTE bands and I guess "Calling PLUS" and there were a way to restore Settings->General->System updates->Update PRL and Update Profile to other custom ROMs for V30, that would open up a lot more opportunities. I hope we hear from [MENTION=2732656]JWnSC[/MENTION] soon as to how the TWRP-flashable stock rooted zips were created and if we can create them for new updates as well.
[LG V30 Guides, News, & Discussion] issc:
so im on boostmobile and yesterday i got my phone and got to us998 and got stuck for 2 hours resetting different settings and roms.

I don't know what it was that I did but I managed to get on sprint's 3g lte (call quality was excellent, text/voicemail worked and just no LTE and also hdvoice wasn't working, so I wasn't roaming into sprints) and i guess this was the part where i was supposed to drag modem files but I was just out of time to try out new things and decided follow this guide to get lte back and just deal with the rest later when I get time.

but I mean minus the bloats its pretty much the same thing right? and sprint apn settings comes preloaded so it was nice.

"app guardian" said it OK'd 275 apps(combination of lg+sprint preinstalls on top of boostmobile raining down **** using radio frequencies or something), really thank you for this lol

-edit

I guess it's not all the same as u998 since nobody's making flashable updates for ls998 =\ but still this is really good temp. maybe one day i can figure the whole thing out so i can rock h930 custom roms.
[LG V30 Guides, News, & Discussion] :
If you look at JWs profile he is not using this phone anymore. I assume hes out.
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
Well that would suck. Somebody figure out how to contact him!
[LG V30 Guides, News, & Discussion] :
Especially since we have this looming issue now with Magisk 17 screwing things up....Magisk Manager updated and I lost root and then flashd 17 assuming it was something new and beter...NOPE

Bootloop city now
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
Oh no! Really? I was prompted to update Magisk Manager and I did. I haven't flashed Magisk 17 yet though. I shouldn't or I'll boot loop?!?
[LG V30 Guides, News, & Discussion] ChazzMatt:
See last few posts of WTF thread.

See here:
[LG V30 Guides, News, & Discussion] eigerzoom:
I can confirm as another successful implementation of sprint working on us998 WITHOUT USING ls998 zips found in this very thread.

DO NOT FLASH THE lg-rctd-disabler-1.0 OR no-verity-opt-encrypt-6.0 FILES AS ONE OF THEM OR THE COMBINATION OF BOTH BREAKS WIFI

IF YOU DO FLASH THEM AND FIND WIFI IS BROKEN YOU CAN READ MY COMMENTS IN THIS THREAD TO HELP GET WIFI BACK WORKING

Flash magisk for root

You just need to have the modem backed up which can be flashed through twrp using the dd method found in the wtf / frankenstein threads

If you want even less steps (avoid provisioning) also backup your modemst1 and modemst2 files (these are specific to your device/plan don't share them)

You back up these files using lgup from working sprint installation (typically before starting the wtf/frankenstein steps)

Make sure you also write down all your APN's while on working stock sprint before starting any modifications, especially the default 'internet' apn.

add the .bin extension after backing them up (or any extension you desire honestly), just use the same extension in the dd steps naturally.

You flash these also with the dd method while in twrp using cmd window from your platform-tools folder on your pc

adb push modem.bin /tmp

adb push modemst1.bin /tmp

adb push modemst2.bin /tmp

adb shell

dd if=/tmp/modem.bin of=/dev/block/bootdevice/by-name/modem

dd if=/tmp/modemst1.bin of=/dev/block/bootdevice/by-name/modemst1

dd if=/tmp/modemst2.bin of=/dev/block/bootdevice/by-name/modemst2

Reboot system and edit your APN's ('internet' should be the only APN needed to add if you flashed modemst1/2 files)
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
Ugh I'm encouraged by this but confused. I don't have all the files you mentioned and haven't attempted to create them. I would welcome more step by step instructions coming from ls99821a stock rooted. I'm really confused about NOT flashing the two zips to disable opt encryption and the other thing (root checker?). Also what about NOT having Update PRL and Update Data Profile? Isn't that a problem for Sprint users? BTW I can't say if I officially have a problem but I'm having data problems both on WiFi and LTE. Many times I "should" have great network access but mysteriously can't connect to common services like Google and Maps and Facebook.
[LG V30 Guides, News, & Discussion] issc:
so im on originally ls998 device and for the life of me i couldnt get mixer path thing going for dual speakers, regardless of what permission i gave to the file i would instantly lose sound and get constant system ui crashes

okay so I took the time do the following:

get on us998 oreo unlocked

install boombox rom - h930 oreo, dual speaker works, no networking

installed flashable modem on top of boombox rom - shows up as ls998/us998, 4G

installed boombox rom again - reads us998 on hardware, doesn't show elsewhere, still 4G and dual speaker works and service provider reads "roaming indicator off"

long story short, what does 4g mean on notification bar for us998, is that the 4g lte or just the 4g?
[LG V30 Guides, News, & Discussion] eigerzoom:
You shouldn't be worried as the sprint modem is available on these forums, sorry i dont have a direct link for you

but it should be in the wtf / frankenstein threads etc...

you can always provision without the modemst1 and modemst2 files, its what everyone does...

I confirmed the device is using the APN to connect with eHRPD in the *#*#4636#*#* menu on us998 and my phone shows the current PRL as 55069

My first boot had 4g working but seemed to deprecate to 3g only...to fix this, these are the steps I performed.

1) Root with magisk 16.0

2) (THIS STEP CAN BREAK 4G - SKIP OR REVERT THIS SETTING BACK TO USC/NAO)

Use a rooted file manager to edit build.prop in the /system folder (i use ES File Explorer Pro)

change: ro.build.target_operator=USC (or NAO) ::: to ::: ro.build.target_operator=SPR

change: ro.lge.laop.default.operator=USC ::: to ::: ro.lge.laop.default.operator=SPR

REBOOT

3) enable usb debugging

4) open cmd on pc in platform-tools folder and use these commands

adb shell

su

am start -n com.lge.hiddenmenu/com.lge.hiddenmenu.ModemProtocol.ModemProtocolMain

5) click 'PDP Setting' and then 'APN Setting'

6) delete the 3G_APN (notice its set as default and hidden in normal APN settings) ... also you can edit all your APN's here and 'save' them in the 3dot menu (dont hit the back button until completely finished)

7) enjoy 4g LTE on US998 on the Sprint network. Bands 41/26 are working - https://i.imgur.com/4HEonqx.jpg
[LG V30 Guides, News, & Discussion] eigerzoom:
you get different icons in the notification bar depending on your build.prop settings

generally speaking the sprint network does not use any other 4g technology besides LTE, but i assume this could change with the TMO merger eventually down the road.

(this is ignoring sprints previous usage of Clearwire WiMax 4g technology)
[LG V30 Guides, News, & Discussion] ChazzMatt:
In other countries, 4G means 4G: LTE. ONLY in U.S. are people confused, due to blatant misinformation from AT&T, T-Mobile that 3G HSPA was "4G".

Open LTE Discovery app and confirm you're on LTE.

( [MENTION=3475147]SGCMarkus[/MENTION], this is what I was talking about just the other day...)

---------- Post added at 02:22 AM ---------- Previous post was at 02:19 AM ----------

LTE is the only current 4G technology. Wi-Max is long dead. ;) . But, yeah for a brief period it was the other mobile 4G technology.
[LG V30 Guides, News, & Discussion] eigerzoom:
I like to be thorough when possible :D
[LG V30 Guides, News, & Discussion] ChazzMatt:
You're one of the few besides me who even remember Wi-Max. ;). I do mention it on occasion, and since this IS a Sprint thread, yeah it is relevant to the 4G discussion...

But U.S. carrier AT&T and then T-Mobile lies (to negate Verizon's huge LTE network advantage at the time) are why we Americans are forced to say LTE or "4G LTE". That's like saying I drive a "car automobile".

It's either 4G or it isn't -- and HSPA isn't. In other countries, in Europe and South America, it's simply "4G" for LTE.
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
Lol and remember when Sprint tried to charge an extra $10/month per line for Wi-Max "premium data" even on devices that didn't even support that technology?
[LG V30 Guides, News, & Discussion] issc:
yeah i must have been confused with 3.9G craps from before

I still have a list of wimax macs that I would cycle through for free service on wimax devices with cloned 3g credentials to keep the cheaper plan (aka SERO)...good times....$30 unlimited wimax 4g

i should probably delete this post though haha
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
I actually still have an Epic 4G as well. It's WiFi only these days but it still works. I used it as a music player for my babies a few years ago.

---------- Post added at 22:54 ---------- Previous post was at 22:35 ----------

For the record, editing the build.prop to SPR may not be necessary but it does add 4g settings to the Mobile Network settings....and its what i did for success on US998 so I included it
[LG V30 Guides, News, & Discussion] ChazzMatt:
While Sprint announced they were dumping Wi-Max for LTE in 2011, they said they would support it though end of 2012.

http://muniwireless.com/2011/10/09/sprint-dumps-wimax-will-build-own-lte-network/

This is now 2018. So, one more year for any statute of limitations to run out... ;). I'm just joking. No one cares about that.

Edit: Wow, there were Wi-Max sites running until 2016?

[LG V30 Guides, News, & Discussion] txag2011:
I must have lucked out. I saw the update and took it, saw i lost root and downloaded the zip and flashed it directly thru TWRP (then rctd and no-verity) and it booted up without a hitch!
[LG V30 Guides, News, & Discussion] elijah420:
I had a WiMax phone as well... The epic 4g.

The smallish town I lived in was 'lucky' enough to not only get WiMax, but the small cluster of towers with WiMax enabled were all right around my house at the time, so I got to take advantage of it. It was good for it's time. Coincidentally, I think said towers served some things here (I'm in South Texas) that were on WiMax until about mid to late 2015 for sure, maybe as far as the actual shut off date.

I had a couple buddies who had ClearWire service here in town as well. It was prevalent and heavily advertised here.
[LG V30 Guides, News, & Discussion] JesseAaronSafir:
On Friday when I was working out at the gym, I had to reboot my V30 because ViPER4Android was on "Processing: No" and I fairly regularly have to reboot the phone to get it back to "Processing: Yes" and for some reason the phone wouldn't come back. I was unable to get it to power on for about 10 minutes and I know that the battery had about 80% charge. I got really worried about it. I was trying to hold the power button or volume down + power for minutes and couldn't get it to power on. I let it sit and after about 10 minutes, I was finally able to get it to power on. And then I saw this:

I didn't reboot immediately because I wanted to finish my workout and be able to play music but I did reboot when it was done and it rebooted without that error.

Does anybody have a theory about what the hell happened to my phone?
[LG V30 Guides, News, & Discussion] ChazzMatt:
I just found out the Japanese V30+ has Wi-Max, besides LTE. They still use it in Japan.
[LG V30 Guides, News, & Discussion] Ainz_Ooal_Gown:
1. You should exit V4A not reboot the entire phone, that should be the last resort.

2. If your with sprint try ##72786# aka SCRTN reset...

Read the Frankenstein directions.

You're the second person today trying to convert to US998 without following instructions.

That's great news. If we can't get the KDZ files for LS998 as new updates are released, I still would hope that someone can figure out what we need to edit in a US998 KDZ or associated zip to put back the Settings->General->System updates->"Update PRL" and "Update profile" options.

How you kept LS998A on yours because I keep getting the us998 version when I go back to stock
[LG V30 Guides, News, & Discussion] travy:
Us998 or ls998

Model number or android version?

Cause you flash the ls998 back to stock one you will be on ls998 you flash the 21aupdate for modem etc you will still be on us998 but have sprint modems etc.

Anyone had any luck converting the last Sprint OTA to a flashable zip? Or the latest US998 kdz to flashable zip? I extracted the Sprint OTA and flashed the modem but did not want to try anything else to avoid losing root. Any help would be appreciated.
[LG V30 Guides, News, & Discussion] :
Seems Sprint has been abandoned by Dev's....moving onto different phones perhaps.

How did you flash the new modem? is it improved anything? Curious!
[LG V30 Guides, News, & Discussion] boxchevy:
I extracted the OTA and changed the modem file to modem.bin. I flashed via adb with Phone in TWRP. You can also change it to modem.img and flash via TWRP img flash. I dont see a difference yet except I am now on US998 20E and have LTE. Before i had problems getting data working properly when using non-stock Sprint roms. If you want to flash 20E flash the kdz choosing DL Partition and select all.but unchecking the recovery and modem.
