[LG V30 Questions & Answers] ChazzMatt:
LG Bridge will look for the KDZ intended for your IMEI, not the firmware you have on the phone right now. Was your phone imported from Hong Kong (China)? Or did you buy from Australian carrier or Australia LG authorized retailer? Did you buy the phone new or used? Have you updated it before using LG Bridge?

Any H930DS can be flashed to run any other H930DS firmware. Best guess is somehow the phone was originally Hong Kong variant and someone flashed it to Australian firmware. When you went to look for update via LG Bridge, then it updated to that region Pie meant for that IMEI.

Unless you have used LG Bridge successfully before and you are sure it is Australian IMEI H930DS?

We haven't always had TWRP-flashable zips. Only thanks to generous, talented devs do we have the collection of TWRP flashable zips for US998, H931, H933, VS996, LS998, T-mobile H932, H930, India H930DS. That's only 8 of at least 20 variants and I'm not even counting all the different regional variants of H930DS...

So you will have to do what we all did before TWRP-flashable zips, and what we will have to do again when some of our TWRP flashable zip devs move onto other phones.

Method #1 -- Works some of the time on Oreo, not yet tried on Pie

This worked for many people in Oreo -- but some still had to reinstall TWRP, reformat data, reinstall the root files. Never could figure out the difference between success and not. Then we got TWRP-flashable zips and the issue became moot.

1) Make backup in TWRP AND make backup of all apps in Titanium Backup.

2) Flash new KDZ via Pie-compatible Dev Patched LGUP in Partition DL mode, but omit the Recovery partitions. Do NOT select "all partitions". This will let you keep TWRP.

3) Boot into TWRP via fastboot commands from your computer, just like when you first installed TWRP using the WTF instructions. (Best not to use the stupid hardware button dance.) Once in TWRP, then choose Reboot to Recovery (from within TWRP) to get the actual internal phone TWRP, instead of the PC TWRP.

4) Flash the Pie-compatible three root files (Magisk, encryption disabler, root check disabler, Magisk again). See

attachments on this post to download those files

.

5) Restore all Data from within TWRP. Do not choose any other categories.

6) Wipe all Caches.

7) Reboot

Restoring all TWRP data may or may not overcome the fact that you have re-flashed encrypted stock Pie on your phone. IF it does work, then after rebooting the phone if anything is still wonky, use Titanium Backup to restore all apps and data (this is in addition to the TWRP data restore you did).

Good luck.

Method #2 -- Works all the time, but yeah you have set up your phone again

1) Flash new KDZ via Pie-compatible Dev Patched LGUP in REFURBISH mode.

2) Your phone is now on the region KDZ you desire and you still have unlocked bootloader. You will need to reinstall TWRP, and then flash the three root files (Magisk, encryption disabler, root check disabler, Magisk again). This includes the step where you reformat all data with a "YES".

See instructions here:

REINSTALL TWRP on PIE stock KDZ with ALREADY-UNLOCKED BOOTLOADER

THAT POST ASSUMES YOU HAVE PREVIOUSLY UNLOCKED BOOTLOADER, AND THAT YOU HAVE NOW UPGRADED TO STOCK PIE KDZ. YOU HAVE UNLOCKED BOOTLOADER and are STILL on firmware which has FASTBOOT FLASH COMMANDS.

Dev Patched LGUP

Dev Patched LGUP vs regular LGUP is necessary when cross flashing across regions or other variants. You will need this for either of the two methods above.

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 Dev Patched LGUP and flash PIE KDZ either via PARTITION DL MODE (but omit Recovery Partitions for your purpose in this thread) for Method #1 or via REFURBISH for Method #2.

Use the attached patched LGUP in this post. If you get a ".dll error" you either didn't install correctly or are using the wrong version of Dev Patched LGUP. Read the installation instructions carefully. Some people have used OTHER versions of LGUP before and ignore the installation instructions -- they think they know how to install and they do NOT --- then complain about .dll error, which is their fault.

* NOTE: YOU CAN NOT USE LGUP "UPGRADE" MODE 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).

3) IF your bootloader is unlocked, it will remain unlocked after flashing KDZ.

!)

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.

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.

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. ;)
