The TWRP flashable 20G file, when being flashed, says "This is the kdz2zip version of us99820f". The TWRP flashable 20F file, when flashed, says "LG-US998 20F Stock OREO". Is there a typo in the 20G ROM code for 20G? I've tried to search the thread but can't find any evidence that's been asked. Thanks again for all your hard work!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Yes, it's possible JohnFawkes had a typo in his flash description for his TWRP flashable zip. I remember telling him about one, perhaps it was even this one.

(WTF...!) LG V30/V30+/V30S Bootloader Unlock & Root Method (With Clear Instructions)​
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] uncklebiggz:
Hello everybody this community is among the best here, twitter and telegram

please inform me of the following if possible

bought a rooted/unlocked us998 with bootloader unlocked and us99820b installed

if I wanted to upgrade, do I flash 20e up to 20h via twrp queue and then flash the respective android 9,10,11, or 12 version ROM?

question comes from a place of clean flashing 30b directly from 20b and experiencing sum issues

apologies for the dumb questions and thanks in advance
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Yes, for the most part. If you want to stay on stock rooted, then stay with 20h (last Oreo). 30b (Pie) doesn't really give more benefits except a newer number and actually takes away some functionality. If you want to flash newer LOS ROMs then yes you do need to go to 30b Pie.

Well it's over 2gig so that's a big security update.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tr4nqui1i7y:
Well it's a full firmware. I meant as far as being different than the last version lol. Not JUST a security update
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] foamerman:
Well I was hoping ChazzMatt would chime in here and maybe let us know what it is or what he thinks about it.

EDIT I don't think we should do anything yet until we find out a little more my 2 cents.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
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".

________

[MENTION=3642089]westwood24[/MENTION], 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!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
I've downloaded it and posted it here in this thread. I have not installed it yet, but just on the surface it seems legit. LG promised security updates at least every 90 days for the V30 to be part of the Google business program. T-mobile is also receiving another Oreo update right now, and H930 received one a couple of weeks ago. So, this seems to be the first wave of further Oreo-based updates.

What is the change log? I don't know. I assume according to the date it was generated it would have May 2018 Android security update. (It's common for the "creation" date in the file name to lag the public "release" date by a month, to allow for internal testing.) Any other improvements? I don't know.

Back when we were on Nougat, I actually skipped 10D on my rooted V30 as it was a pain to install, and stayed on 10C as I knew Oreo 20A was coming very soon. I'm hoping for a flashable zip version of this KDZ.

If you do flash it in LGUP, if you already have TWRP make sure you leave off the recovery partition so you can keep TWRP. That puts you one step ahead in getting back to root.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] foamerman:
Thank you for your input on both of your post's ChazzMatt Yes let's hope westwood24 can make us a flashable zip for this yea-ha.

Just updated.

May security patch. Still 8.0

Will report if I notice anything different.

Default APN read from my sim card is now read only.

Had to manually enter a new one, where previously I just modified the default one.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Thanks for the report.

If Oreo 8.1 is ever released for V30, the Korean carrier variants will get it first. Then everyone else later.

Same with Android "P" or any new features. Like the ThinQ AI camera, which came with Oreo -- Korea carrier variants got that first.

That's not to say this update may not have some tweaking or code improvements... But no one should expect unicorns falling from the sky for a minor "letter" update (20A to 20B). ;)

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
No. You can't change the bands of the H930DS that we know of...

Many people who bought have asked because H930DS doesn't have LTE bands for most North American carriers.

If i used this to flash KDZ ，I was not supposed to restart v30 when it was done but volume- power to reset my phone so i could go back twrp then i flash magisk and no-verity. In the end the v30 is new,no any data and apps,right?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Right. It will wipe data.

You should be able to boot to TWRP via fastboot from computer if you don't want to do the hardware "button dance"

"Upgrade" (instead of selective DL PARTITION) would keep data and apps, but would wipe out TWRP.

Then reinstalling TWRP would still wipe data and apps.

AND you would still have to root and flash the other two files.

At least with selective DL PARTITION you have kept TWRP.

This is the one going to my sister who hasn't found the time to accept her gift yet. She'll be using it on AT&T. I used "upgrade" because this one is not bootloader unlocked nor rooted, as I only see her every 2 or 3 months and don't have time to explain to her why the scary bootloader unlock warning is nothing to be worried about.

Can this be done with the latest vs996 file? Or would I lose root, and fastboot commands???
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
If you tried to flash to Verizon VS996, you would lose root and fastboot flash commands.

You would be Frankenstein converting to a Verizon firmware, instead of the carrier unlocked model which will run on Verizon.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] suzook:
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
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] dvgb173:
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.

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?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
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.

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?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
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 [MENTION=3642089]westwood24[/MENTION] 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!

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. ;)

It doesn't look like you were using uppercut, but just in case you were, it doesn't work with Windows 10 because of how the latter permissions Program Files folders.

So will I get ota updates in the future after flashing this? I don't know why I did not get ota updates? Does that happen to everyone? Is LG just weird?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
1) Full image KDZ is preferable to partial image OTA anytime.

I really don't understand the hangup over OTA updates. In the Motorola Quark forum, we cautioned over and over against OTA updates. They usually messed up something. People were urged to wait for full image and flash that.

(And to be sure to unlock bootloader BEFORE installing and update, as Verizon in particular was always trying to patch bootloader exploit. If you took OTA or flashed full image of the new firmware, before unlocking bootloader, you could not go back.)

2) But yes, an OTA update should be offered by LG when available.

However, just like with India Oreo the full image KDZ was available weeks prior to LG India releasing OTA update. Why wait?

This US998 20B is available via full image KDZ. Since I prefer to flash the full image KDZ anyway, I don't really care if/when the OTA version ever comes.

Also, since I would like to keep custom recovery, I can't flash OTA. Whereas with full image KDZ, you can selectively flash partitions. OR you can even flash the TWRP flashable zipped file.

If you have TWRP and are rooted, flash this KDZ via LGUP with DL Partition method, but leave out "recovery" partitions to keep TWRP. You will then then to boot to TWRP via fastboot, install Magisk and the other two files (just like you did when you first rooted). But you'll have a head start by already having TWRP.

Due to the July 2018 LG security patch blocking the WTF bootloader unlock exploit, I've added instructions in post #1 of this thread to use dev patched LGUP to downgrade to earlier versions of US998 KDZ. You can always update to newer firmware AFTER bootloader unlock.

It's basically a variation of the Frankenstein method, but you are just Frankensteining to earlier Oreo KDZ, before the bootloader unlock exploit was patched.
