[LG V30 Guides, News, & Discussion] ChazzMatt:
I've been reading reports from other LG models (like LG G6), where LG has LG Bridge downgrade the phone back to Nougat first before then updating to Pie. LG Bridge uses full image KDZ, temporarily downloaded to PC.

So for installing the KDZ, I suggest FIRST downgrading to US998 Nougat 10d via Partition DL mode, Master Reset, then Refurbish to US998 Pie KDZ. Here are the steps...

If you have problems flashing this US998 Pie 30b KDZ, see

post #6

for FOUR more workaround methods proven to work for some people.

You should probably use this method (DOWNGRADE to NOUGAT first) even if you have TWRP installed. Then reinstall TWRP again after successfully updating to Pie.

KDZ INSTALLATION INSTRUCTIONS

0) Turn off phone, manually go into Download mode before opening Dev Patched LGUP.

1) Using Dev Patched LGUP from THIS thread, flash

US998 10d Nougat KDZ

via Dev Patched LGUP using Partition DL mode. Select ALL partitions.

2)

Master Reset

. This is NOT Factory Reset.

3) Boot up to Welcome screen. Turn off phone, manually go back into Download mode.

4) Flash

US998 30b Pie KDZ

via Dev Patched LGUP using Refurbish mode.

5)

Master Reset

. This is NOT Factory Reset.

If you did not unlock your bootloader before doing this, then you bootloader is still locked -- because that's what you want. Finished. Set up your phone.

If you had unlocked bootloader before doing all this, you will still have it. Boot to ADB, and

PLEASE follow these instructions for re-install TWRP and root!

See Installation instructions for KDZ. That is your best chance of success. Then re-install TWRP after successfully updating to Pie KDZ. Your bootloader will still be unlocked. These instructions below are if you are stubborn and don't want to do that...

Flash the "ROM" with latest TWRP. Flash Magisk + [MENTION=6815443]JohnFawkes[/MENTION]

AnyKernel 3 RCTD Remover

(root checker disabler) 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.

This TWRP flashable zip has the new Pie encryption disabled. No encryption enforced, but you can encrypt in TWRP if you want afterwards.

The dev recommends formatting data before installing this TWRP-flashable zip: "format data before flashing, not wipe but format". That's your decision. Others

have not.

*

Stable TWRP 3.3.1 is recommended

by our TWRP dev for Pie.

TWRP-FLASHABLE NOTES:

If those instructions above do not work for you for some reason, then go through these full blown steps (adapted from Section 6 of WTF Instructions):

a. Wipe Data – Factory Reset

b. Install – set storage to the External SD (if you have a microSD card) OR drag necessary files over from PC once in TWRP.

c. Install the TWRP-flashable zip

d. Install the

latest stable Magisk zip

.

e. Install [MENTION=6815443]JohnFawkes[/MENTION]

AnyKernel 3 RCTD Remover

(root checker disabler); this disables LG's firmware root checks, which may impede performance.

f. FORMAT DATA (Select WIPE, then FORMAT DATA, then select yes.)

Do NOT delete your OS, but you do need to FORMAT your data , not just "wipe" it this time. Otherwise you may get an encryption error when you boot up the first time. If you get any red mount errors, go back to the TWRP reboot menu and select reboot to recovery and try to FORMAT DATA again. Then, after successfully formatting...

g. Reboot – "Reboot Recovery" from TWRP reboot menu (choose to reboot back to Recovery). Now that the data partition has been formatted, TWRP needs to reload the recovery partition for usage. If you skip this step, when Magisk is installed again below, it may think that /data is still encrypted and set "preserve force encryption". This is also a good sanity check that LG encryption has been removed from /data.

h. Re-flash the

Magisk zip again

. (This is to make sure, due to Pie changes.)

i. Reboot – to System (NOW you are finally rebooting your phone! Until now this whole section has been done within TWRP.)

STRONG SUGGESTION: After successfully doing all this, when you finally boot back to LG Pie, install an app like this to easily facilitate rebooting to TWRP recovery in the future:

Recovery Reboot

. Allow it root privileges when asked by Magisk and put icon shortcut on your desktop.

Also, please make another TWRP backup. ;)

Here's how to flash with LGUP:

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

UPGRADING LG V30/V30+/V30S TO PIE KDZ FIRMWARE WITH LGUP

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

2) open patched LGUP and flash PIE KDZ either via UPGRADE (to keep your data, but see Note about TWRP) or via REFURBISH or PARTITION DL. If the latter, then in the pop up box "Select All". Use the attached patched LGUP in this post.

* NOTE: YOU CAN NOT USE LGUP "UPGRADE" IF YOU HAVE TWRP CUSTOM RECOVERY. LGUP "Upgrade" is like a manual OTA and is only for pure stock (but you can have unlocked bootloader). If you have TWRP custom recovery and want to use LGUP, then use PARTITION DL OR REFURBISH which will NOT keep your data and will wipe out TWRP. Or use the TWRP-flashable zip (ROM) instead of LGUP, which will keep your data and will keep TWRP.

3) IF your bootloader is unlocked, it will remain unlocked. If it's not unlocked, then you will just be updating to Pie -- but will have to temporarily downgrade to early Oreo if you ever want to unlock bootloader for root.

HOW TO INSTALL DEV PATCHED LGUP

0. UNINSTALL any prior LGUP version. Seriously. Go to Programs folder and delete the LGUP folder if you must.

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

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

Follow the prompts to complete the install.

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

5. Launch LGUP using the desktop shortcut. NOT from folder icon!

As mentioned before, use UPGRADE, REFURBISH or PARTITION DL modes. REFURBISH and Partition DL are probably best.

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

I don't care what anyone else tells you. If you listen to them, let them help you recover from messing up your phone.

https://9to5lg.com/lgup-1-15-manual-how-to-unbrick-restore-your-lg-devices-with-lgup/

It's all 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.

Reboot the computer.

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