[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
For bootloader unlock purposes, use the US998 KDZ versions with pre-July 2018 security patch: I recommend 20a or 20b.

Look at the names for dates in the title. You can always update to newer firmware later, AFTER bootloader is unlocked. Flashing a newer KDZ will not relock your bootloader. See bottom of post for instructions on how to downgrade to earlier firmware.

ONLY USE MAGISK 18.X ON OREO TWRP-FLASHABLE ZIPS!

If you are installing/updating latest US998 firmware for the first time after bootloader unlock/root, you should flash 20e zip (below), then 20f zip, 20g zip, 20h zip back-to-back in TWRP, then flash Magisk. If you go straight to 20h via TWRP-flashable zip from very early Oreo, you will most likely have problems. There were massive changes starting with US998 20f and you need the prior 20e as foundation before going on to 20h. You should also do this if coming from a custom ROM.

Flash the "ROM" with latest TWRP, after wiping caches. Reflash Magisk immediately afterwards, before rebooting to system. It's just stock KDZ but in TWRP-flashable version. Not debloated nor meant to be updated in the future. It's just a very convenient mechanism to have newer stock firmware instead of using dev patched LGUP to flash partitions, etc. Go to

this thread and thank him.

Screenshots below are for previous firmware and only demonstrate how to upgrade full KDZ using LGUP.

NOTE: This is for all V30/V30+/V30S US998 -- open market US998 V30/V30+/V30S, as well as U.S Cellular US998 V30/V30+.

Here's my own US998 V30+ updating:

__________

HOW TO (temporarily) DOWNGRADE BACK TO OREO FOR BOOTLOADER UNLOCK

(or DOWNGRADE BECAUSE YOU DON'T LIKE PIE)

1) DOWNLOAD FIRMWARE AND DEV PATCHED LGUP

* Download Oreo KDZ you wish to install -- for bootloader unlock would be US998 20a or 20b. You can update to more current firmware AFTER unlocking bootloader on early Oreo.

(If you just don't like Pie, then choose the most recent Oreo KDZ, which is US998 20h at the top.)

* DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by [MENTION=2651082]tecknight[/MENTION]:

https://androidfilehost.com/?fid=11410963190603845019

(Or use attached file from bottom of this post. Thanks to [MENTION=2651082]tecknight[/MENTION]! Please

go here and click the THANK BUTTON

!)

_________________

2) INSTALL DEV PATCHED LGUP

0. Uninstall any prior LGUP you have. Uninstall anything like Uppercut, which no longer works and causes conflicts with this Dev Patched LGUP.

1. Extract LGUP_DualMode.zip to a folder on your PC.

2. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.

Follow the prompts to complete the install.

3. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode

4. Launch LGUP using the desktop shortcut, NOT the Install folder shortcut.

Choose Process : PARTITION DL (all partitions) or REFURBISH

----------------------------

3) DOWNGRADING/UPGRADING ANY LG V30/V30+/V30S TO OREO KDZ FIRMWARE

1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)

2) open patched LGUP and flash OREO KDZ to DL PARTITION mode. In the pop up box "Select All". Use the attached patched LGUP in this post.

You can also use REFURBISH mode, if you wish.

3) Master Reset (

post 101 of Frankenstein thread

)

5) DONE.

It's fairly easy. Most people breeze right through this. But if you have any problems, go through this list:

Make sure you in download mode BEFORE opening the patched LGUP file.

This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,

Try different USB port,

Try different USB cable,

Try different computer.

Reinstall

LG mobile drivers on your PC.

Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).

REBOOT THE COMPUTER.

If you ask for help, that's the list of items we are going to give you anyway. ;)

WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.
