Hi. I noticed bilong9's korean zip ver is not that working perfectly...
In some area, voice call won't work well if mobile network setting is set as LTE/GSM/WCDMA Auto.
So, I made a flashable zip version of Korean ROM.
It works well and no data/call problem, and also have DTS:X 3D

Original ver : V300S/K/L21_p/r for LGM-V300S/K/L

Changelog:
2019.04.07 : Updated to 21p version.
2019.04.11 : Added K/L version
2019.04.19 : Updated to 21r version.
- Google security patch
- In montly widget, fix don't automatically go to next month problem.
2019.06.24 : 21s ver patch. Thanks to @PjLyTam, who made it. Go to #46 Thread.

How to flash
1. You need to have custom recovery. If not, root and get it from here for root Korean V30.

Also get
1Magisk-v16.0.zip
2no-verity-opt-encrypt-6.0.zip
3lg-rctd-disabler-1.0.zip
From here. (Thanks to @bilong9 @darkidz555 @ChazzMatt)

2. If you already have custom recovery, backup all your data/system for safety

3. In recovery, go to wipe, then format Data, then Factory reset, then advanced wipe , select Dalvik/ART cache, data, system, cache (if you want to make sure, select internal data too)

4. Get Zip you wanted.
1) 21p version (Released at 2019.02.14)
For SKT : LGMV300S21p
For KT : LGMV300K21p
For LGU : LGMV300L21p
2) 21r version (Released at 2019.04.18)(NEW!)
For SKT : LGMV300S21r
For KT : LGMV300K21r
For LGU : LGMV300L21r
3) 21s version made by @PjLyTam, here.

If above files are not working or get error, try this.

5. Flash LGMV300S/K/L21_p/r then flash
magisk if you need root permission,
no verify opt for internel storage access in recovery,
rctc disabler for bypass LG rctc check.
+ I found don't install magisk can cause bootloop. Try install all 3 zips (At first, install magisk can return error. At that case, reboot to TWRP again and install all 3 zips. It will not return error at that times).

6. Done!


Its pure stock version, so it has Korean bloatware... I will remove it when I have some time.



It will work with no additional steps cause this rom contains all things (system, modem, boot, also other crucial components...).
If I have some time, I will remove some bloatware in /system.
+ This zip don't remove TWRP, cause it didn't flash recovery partition.

Thanks for this! You'll get 10 posts soon enough. When that happens, one of us can ask it be moved to the ROMs thread.

Can Korean model users flash this immediately after WTF bootloader unlock/TWRP installation or do they still have to do the extra steps previously for Korean models (flash US998 zip to get modem back, etc)?

The Korean models had an extra degree of difficulty, it seemed...

What I do is :
1. Get TWRP by using Korean root method
https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505/amp/
2. Flash H930 rom zip made by bilong
Link : https://forum.xda-developers.com/lg-v30/development/rom-h930-21h-lg-v30-mv300v300-korea-t3871188
3. Wipe data...etc using TWRP
4. Flash 21oV

But flash this after get TWRP would be no problem (if using Korean root method)
(Because this rom has same install method as bilong's zip, only files are different)
If I have time, I will try install after get TWRP.

You're on your own with that. :p

Lols. :cyclops:

Yeah, I know. I'm one of the more unique ones. It's the only way so far I can get the required modem files that will work with carriers here. EU ones work as well but signal reception is atrocious. Running stock US fw, I get no signal even in global mode. On the plus side, running KR fw gets every single feature LG releases for the V30 with the small caveat that some of them are in korean. Haha

That said, I've only ever tried the US fw using KDZs. Haven't actually tried a twrp flashable one with build.prop edits.. Hmmmm....

If it's alright with you, I'm going to ask the mods to move this ROM down to the ROM section. I know you couldn't post it there initially as you didn't have enough XDA posts under your belt. But you are close, and you have maintained this for a month now, with updates.
