Ok, Thanks!

Sorry, one more question. I pick up a ls998, convert to us998, then could i completely convert to vs996? My wife needs a phone, and wants a "stock" VS996
You could do that.
You could probably skip the US998 part and just flash VS99620b_03_0312_ARB00.kdz directly with Developer LGUP and the Partition DL option.
Then you just have to get Verizon to activate it. If you do the Bring Your Own Device, Verizon will offer you a new sim.


I do not think the Verizon Software update will work on the phone though. You will have to manually apply updates. It never worked when I had my
US998 flashed to VS996. But I also have the V30+, which Verizon doesn't carry. I think it was more because my IMEI is not from the Verizon device list.


Let us know how you make out.

Looking for assistance here. I'm unlocked and rooted and after foolishly fooling around with some 930 roms I'm back on this install but alas I have no data connectivity (on t-mobile). My first thought is to restore the US998 unlocked radio firmware and if so can someone provide the link to make that happen. If another solution is warranted will appreciate any info.....

You've double checked T-Mobile APN settings?

Unfortunately I missed your post and I went ahead and re-flashed giving up TWRP and root in the process. I goofed again by flashing the wrong kdz ending up with 7.1.2 on my device. Oh well - at least I have data....

You can always root your phone again.

Also, next time if you have TWRP, do DL PARTITION method, but remove "recovery" partition and that way you'll keep TWRP.

That's what I did before the original problem came up. It's interesting to note that the ID on my device before my recent flash came up in the LGUP as a 930. Only a full upgrade returned my device to the correct 998 identifier... question LGUP doesn't seem to work for 7.1.2 to upgrade to 8.0. How best to get it back to 8.0 before I root again?

The dev patched LGUP does work. Just read through the Frankenstein post again to see how to go from Nougat to Oreo. You have to do a master reset between US998 Nougat and Oreo KDZ.

Also, go into download mode BEFORE opening the patched LGUP.

Are you on the latest version? Wondering if I should upgrade. Anything you notice better?

Ok I'm back on 8.0 but now during the TWRP installation I managed to wipe my system. I'm in TWRP right now with no system to boot into - is there a way i can sideload this kdz to give myself a working rooted 8.0 device?

Hmmmm...

Two ways.

1) you can drag a ROM of your choice over from your PC and flash it in TWRP, just to give you something to boot to temporarily (if needed). Make a TWRP backup.

With that safety blanket, turn off the phone, go back into download mode, and do the rest of #2.

Or

2) just turn off the phone, go into download mode BEFORE opening the patched LGUP, flash the Oreo KDZ via DL PARTITION method.

But do not select recovery partition. Flash all partitions, EXCEPT for recovery. That will leave you with TWRP still installed.

Then fastboot boot into TWRP, flash Magisk, no encryption file, don't check root file, etc.

Depends on how brave you are, if you want to go into download mode with no OS backup. I would do #1 first, just in case, and make a TWRP backup.

You're still doing the same thing (#2), either way.

______

When @westwood24 gives us the TWRP flashable zip 20R update, you could just drag that over and flash it like a ROM. We don't have that yet... We thank him for doing that for us!

Dev patched would probably recognize it if you reinstalled LG mobile drivers... I have to do that at least twice a week.

For non-dev, I guess go with upgrade or refurbish. But you'll have to reinstall TWRP.

i tried the usb driver update - didn't work then i went ahead with with non-dev and was unsuccessful with two different kdz's (compatibility issues). You wouldn't happen to be privy to a t-mobile friendly us998 compatible 8.0 ROM would you ? ;)

Maybe.

WETA_US998_20a_beta.zip
https://androidfilehost.com/?fid=674106145207485360

That's an Oreo beta version of the US998-based WETA ROM for V30 by @Mentalmuso.

His stock-based US998 Nougat ROM was well-respected, and he was working on Oreo update but has not released it yet.

His Nougat ROM will NOT boot on any phone that has Oreo installed, but this Oreo beta will. However it is beta, and based on 20A -- not as polished as his Nougat ROM. Someone said it doesn't have all his usual mods and stuff. But hey, any port in a storm. ;)

Here's a discussion @MetaMaverick had with the dev @Mentalmuso about 2 weeks ago:

@Whiskeyomega Boombox ROM works if you use T-mobile APN.

From the BoomBox thread:

I just flashed this ROM last night and am having exact same issue. I'm on T-Mobile and the data is gone.

Edit: had to add an T-Mobile APN entry as per here:
https://support.t-mobile.com/docs/DOC-34124

Just go to the the APN settings under network and modify the tmobile apn.. With this=
https://support.t-mobile.com/docs/DOC-28474

LTE SHOULD START WORKING. i have us998 on tmobile also :good:

    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.

    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.

    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.

    No, not worth it. It's just September security update. We'll have November in a few days (probably), and TWRP flashable.

    Sent via open market LG US998 V30/V30+

    Yep im working on the us998 20E flashable now. Ive have it uploaded later tonight when i get off work. Ill also be taking over the kdz flashable zips for us and verizon from now
    9
    Added US99820b_03_0524 KDZ (2.76Gb)

    Right now with this full KDZ, if you are already bootloader unlocked and rooted, to update you need to flash via dev patched LGUP with DL Partition method -- but leave off "recovery" partition to keep TWRP custom recovery. Then in TWRP, reflash Magisk, the "no encryption" file and the "don't check root" file.

    If you don't do that, and flash the full KDZ, you will also have to reinstall TWRP.

    If we do get a TWRP flashable zip, I'll post the link here in this thread. Then you can just flash THAT in TWRP like a ROM... Until then you can NOT flash this with TWRP. Do NOT post messages that you cannot flash in TWRP. I'm telling you that already. ;)

    If you are not bootloader unlocked and rooted, then just flash via LGUP with "upgrade".

    ________
    @westwood24, can please make us a flashable zip of this KDZ please? You can make your own thread like you did with the H930 update and I'll link to it. Thank you!

    Tommorrow i will upload the rom
