[US998][STOCK][OREO]LG V30 US998 US99820h_00_0318.KDZ

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.

JohnFawkes said:

Also flashing magisk in between each and rebooting in between each is not needed. You can add all (zips) to the queue and flash at once then flash magisk and then reboot. Tested this method with the us998 zips and works just fine

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 @tecknight:
https://androidfilehost.com/?fid=11410963190603845019
(Or use attached file from bottom of this post. Thanks to @tecknight! 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.

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

3) ChipErase: Dangerous, This will erase IMEI/efs, Do not try this if you do not have a NV backup.

I know everyone has their own settings, but for new owners who want a reference point for all the various submenus and customization, I'll share screenshots of my settings. You can always change to what you like.

We now have two working download links -- Android File Hosts and Codefire. I'll add the LG Bridge server link when it becomes available. Now I have to actually flash it myself!

DONE. See screenshots.

jeston said:

Thanks for this. So what all do we need to do in order to root again after upgrading? I assume this wipes everything, correct? So do we need to re-flash the new TWRP after we upgrade, then format data and flash the no verity script again, then install magisk? Or is the format data and flash no verity not needed if we've already done that on Nougat? I'm pretty new to using KDZs.

EDIT: changing this answer based on people's experiences.

Yes, you will lose root and custom TWRP recovery. You'll have flash/reinstall those. Be sure to use the Oreo compatible TWRP 3.2.1:

Yes, I updated my still-bootloader locked US998 V30+ immediately. I'll do my bootloader unlocked, rooted US998 V30 later...

agamemnonn said:

I just relock bootloader before flashing. But now i have warning "your device has failed a routine safety check and will not boot" and does not even get into bootloader mode. Do you have any idea?

See this thread for the V20 but you need KDZ for the V30.

https://xdaforums.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903

You should still be able to use Oreo KDZ and LGUP, I would think.
_______
EDIT:
After further discussion, I've removed instructions to re-lock the bootloader as people have successfully upgraded without doing that.

Deleting this post as information has changed. Do NOT re-lock the bootloader.

i didn't relock the bootloader and haven't had any issues

Really? I was just going by what happened in another thread.Fantastic if we don't have to, for those who have unlocked BOOTLOADER. I'll change instructions when I get home.

You just had unlocked bootloader and root, no custom ROM?

I'm updating my other phone with unlocked bootloader tomorrow.

jeston said:

All I know is I updated a couple times with the kdz so far and never relocked, but that was just nougat to nougat. Wasn't sure if it was different for nougat to Oreo.

Tomorrow I'll test with my bootloader unlocked V30.
