Yeah also seems those who didn't flash pie kdz and used your zip have rct disabled.
Yesterday I flashed kdz, then installed twrp again and flashed zip to have DTS and weather animations. RCT is enabled here. So I guess if I downgrade to oreo kdz and install twrp, rct disabler and root, then I install Pie zip, rct will stay disabled (hopefully).

that's because he didn't flash KDZ first

:good: which would've rewritten op partition with new data, including version numbering :)

Interesting.

What happens if they flash the TWRP flashable zip and follow all the directions to reformat data. Also maybe re-flash the RCT file AFTER reformat data with the 2nd Magisk flash?

You mean they do this after pie kdz? Or do it without flashing pie kdz:confused:
I think the result of not flashing pie kdz would mean rct disabler will work, no matter what you do.

rctd stuff is a bit tricky: everyone who flashed kdz first and then the zip, has rctd disabled in any case. the screen you see in lg dialers hidden menu, telling you that rctd is active, is the content of a simple text config file present in /persist-lg/rct, which gets written via a startup .rc file when first booting up the kdz. the daemon itself is removed when flashing the zip afterwards, but the config file stays. hidden menus rct screen is reading and displaying it, nothing more.
so, if you delete this persist-lg rct folder in twrp (mount partition and navigate to it with twrp file explorer), the message in hidden menu is gone and showing rct disabled. coming zips will have the removal of this folder included, just to be sure :good:

i'll update the zip thread on weekend, i've got no time earlier than that, sry :( a new zip (v3 xD) with op partition included, we took this partition from a phone which has pie kdz flashed and put it into the zip then. op partition extracting somehow isn't working anymore, no matter which tools version we use. sth changed in pie kdz / dz, which makes it impossible to get it atm.

OP includes all the configuration required for VoLTE to work. So VoLTE won't work for anyone
Yeah there are problems trying to extract OP partition. But most previous twrp zips came without OP image. So something in pie is messing up.

That's why I don't understand about the no VoLTE thing. Most previous TWRP zips didn't have op image and VoLTE works just fine.
@seadersn?

Good!
op contains all the config stuff for different providers and volte / vowifi / apn's etc pp. also some apps which are loaded on first boot-up. if no op img is flashed, the old one is used.

Any way to add CDMA support to H930_30B? Rom works fine on us998 except GSM only
This is the H930 Oreo KDZ thread. There's no H930 30b (Pie) posted here. ;)

H930 variants' radios are not compatible with any North American variants.

Maybe "GSM" (as in 2G) but you don't have LTE, right? If you do, I'm very surprised.

Hi @ChazzMatt

Me again! This time I am working on the H930DS I bought for my wife
I downgraded to H93020r_00_OPEN_EU_OP_0518.kdz with LGUP (I followed this guide) so I could unlock the bootloader; All went fine.

My wife is not so much into rooting the phone as she won't be going onto a specific rom (e.g. Lineage as I did); she intents to remain on stock rom but I thought I would at least unlock the bootloader now (for future evolutions...) and then upgrade the phones' firmware to the latest version: H93022j_00_OPEN_EU_OP_0403.kdz.
I'm following the same guide with LGUP but this time around LGUP displays a "There is no handset connected. Please connect a handset(s)." and won't detect the phone once connected; "LGE Mobile USB Serial Port (COM...)" does not display anymore in the device manager, so, while investigating the issue, I stumbled on this part:
If you are installing/updating EU H930 firmware for the first time after bootloader unlock/root, you should flash 21o zip AND 21w zip (below) then new 22j zip back-to-back in TWRP, then flash Magisk. If you go straight to 22j via TWRP-flashable zip, you will most likely have problems. There were massive changes starting with 21w and you need the prior 21o as foundation before going on to 21w and 22j. You should also do this if coming from a custom ROM.
Is this still true?
Does it mean I MUST root the phone, install TWRP then flash 21o, 21w and finally 22j back to back to upgrade the phone / I cannot flash 22j with LGUP?
Thanks for your help.

No, you misunderstood. If you look you will see in that note I'm talking about TWRP flashable zips. For people who have bootloader unlocked, installed TWRP and rooted -- now to update via TWRP flashable zip, you have to go through those stages.

For those who are using LGUP, you can flash to most recent KDZ.

You can still install TWRP and root at your convenience on most recent KDZ, as long as you have unlocked bootloader. So, you are doing it right to go ahead and unlock the bootloader now.

I'm following the same guide with LGUP but this time around LGUP displays a "There is no handset connected. Please connect a handset(s)." and won't detect the phone once connected; "LGE Mobile USB Serial Port (COM...)" does not display anymore in the device manager.

Have you tried going into Download mode manually first, before opening LGUP? Sometimes also helps to reboot the PC between flashes, so it's seeing things fresh.

Thanks @ChazzMatt
As I said bootloader is unlockes already.
So I shall try LGUP again as per your recommendations (it makes sense then to root and flash twrp now to avoid any future hassle!)
Thanks

er, how do i go in download mode manually please?
(i use adb / fastboot on my linux to do so (to unlock bootloader) but switch to my son's windows PC to use LGUP (as there is no debian alternative)

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 or PARTITION DL. If the latter, then in the pop up box "Select All".

Your bootloader should remain unlocked. At that point on most recent Oreo KDZ, you can then install TWRP, flash the three root files (decryption disabler, root check disabler, Magisk) and root. You will then have rooted stock firmware.

Thanks @ChazzMatt - will try this tomorrow.
Will keep you updated.

    For bootloader unlock purposes, use the H930 KDZ versions with no later than July 2018 security patch: 20d or 20r.
    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 this post for instructions on how to downgrade to earlier firmware.

    If you are installing/updating EU H930 firmware for the first time after bootloader unlock/root, you should flash 21o zip AND 21w zip (below) then new 22j zip back-to-back in TWRP, then flash Magisk.

There were massive changes starting with 21w and you need the prior 21o as foundation before going on to 21w and 22j. You should also do this if coming from a custom ROM.

    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. 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.

    Thanks to @suunnittelija!

    Here's how to flash:

    ----------------------------
    DOWNGRADING ANY LG V30/V30+/V30S TO EARLIER 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 pre-July 2018 security patch OREO KDZ to DL PARTITION. In the pop up box "Select All". Use the attached patched LGUP in this post.
    3) Master Reset (post 101 of Frankenstein thread)

    (For bootloader unlock purposes, use the KDZ versions with pre-July 2018 security patch: 20d or 20r. You can always update to newer firmware later, AFTER bootloader is unlocked.)
    5) DONE.


    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 EU H930 20d or 20r. 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 22j 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 EARLY 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.

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

    SETTINGS

    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 TWRP-flashable version of H930 21H KDZ, thanks to @seadersn. See below and also linked in post #1.

    LG-H930 EU OPEN 21H ROM

    If you are already on H930 stock firmware, dirty flash like a ROM to upgrade. Reflash Magisk afterwards. 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 latest stock firmware instead of using dev patched LGUP to flash partitions, etc.
