Yes, VS996 worked like a champ. I tried the other because it was brought up in another thread. I was curious if we would be able to flash any fw or if it would just be VS. There is some sort of correlation between the 998 and 996, probably because they're all factory unlocked. Probably the same device with different carrier(or no carrier) stuff.

I see. Sad that your device bricked. Hope you can find a solution, at least your findings are gonna be useful for people down the road.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mikeyinid:
My V30 is definitely fixable. These guys fixed the same issue HERE

I'm not sure where they got those files though. It changes the partition table through QFIL, but they're device specific. I just need to figure it out if they dump them from the device or if they're in the KDZ. If I can just get into DL mode on my phone I can save it.

I unlocked my Sprint LG V30+ through an eBay seller claiming his SIM unlock technique was 100% successful. I was hesitant and grilled him about his methods before caving in and letting him tinker with my phone. I think it's the same method as the Chinese person on Baidu. It's done through LG Octopus and a custom US998 firmware that is modified to work for the Sprint variant. I am using it with a global AT&T SIM (working 100%) and the software appears to be stock Nougat US998 with no bloat.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Very interesting. Thank you for that information! So, this Octopus box can do some magic. Wow.

But you haven't received any notifications for AT&T Oreo? I'm curious if your phone will allow you to update even if you flash AT&T Oreo KDZ with LG Bridge? Or maybe there's only a certain partition the update can be flashed to. I don't know.

"AS998" is from a regional U.S. carrier. (see this

thread back in November

when I was researching them.)

"US998" (as you know) is the model number for both U.S. Cellular and the open market LG US998.

I bet they're both pretty much identical firmware which allows LTE/CDMA/HSPA/GSM.

I'm curious whether any of these problematic LS998 Sprint phones converted to "good" US998 or AS998 firmware can be updated via OTA or even LG Bridge?

ANSWER: apparently during the conversion your Sprint phone is given a corresponding US998 or AS998 IMEI (illegal in many countries and cannot be discussed on XDA), your phone will receive updates:

So, this would be the same for the "US998" Franken-phones. When you get the phone converted it has to be done completely, in order to receive OTA updates or updates via LG Bridge.

I wonder if these people with fake US998/AS998 phones (firmware only) but still bad IMEI (Sprint) can flash it with LG Uppercut?

UPPERCUT: Add Any LG Device to LGUP for TOT/KDZ Flashing

https://xdaforums.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295

That would keep the phones "legal" (original IMEI) but still allow for firmware updates.

I have gone through the thread as advised

I saw two users post that they go their phone unlocked and it is working perfectly fine.

But I need clarifications on what needs to be done(I do not have octopus and I don't know if this is a requirement for the sim-unlock process).

Should I flash the US998 kdz you posted here using the steps specified here.

Or ther are still some things that needs to be done.

I will appreciate you response as I'm about to give it a trial.

Thank you.

LG V30 US998 US99810d_01_0411.KDZ now posted.

Not Oreo, as discussed but still an update.

April 1, 2018 security patch.

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] texas83:
For this latest kdz, the 10d version, will I be able to root afterwards? If yes should I just flash magisk and will it retain twrp or no? Thanks.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Are you already rooted? Yes, no?

If no, is your phone eligible for root? (open market LG US998 V30 bought from authorized retailers like B&H Photo, not U.S.Cellular model)

If yes to either of those questions you can be rooted (or rooted again) with this KDZ. However if rooted now, you will need to temporarily lock your bootloader again, and then after flashing, unlockbootloader/install TWRP/root again.

If already rooted, make sure you have your unlock.bin file that LG sent you -- since you will need it again.

If you've not done any of that yet, this update shouldn't make you ineligible for bootloader unlock. That eligibility is decided by the IMEI range in the LG Developer Bootloader Unlock list website, not what version of firmware you are running.

My open market LG US998 V30+ cannot be rooted right now, and I'm keeping my wife's open market US998 V30 just stock. (I don't have time to mess with two rooted phones.) So those two are now on the latest Nougat 10D.

My other open market LG US998 V30 (my spare) is bootloader unlocked, rooted, has TWRP and is still on earlier 10C. For me, right now it's not worth the hassle of what I just described to you, when I feel Oreo is coming very soon. I'm already on the "Oreo" compatible TWRP on that one. When US998 Oreo comes, I'll decide then whether to relock bootloader, upgrade or leave as-is and just install US998-based Oreo custom ROM. I've resisted installing any ROM (even though some are already Oreo -- based on South Korea/Europe Oreo) because I've been helping out the T-mobile guys.

Yes, I flashed my locked LS998 into VS996 with LGUP developer mode (PARTITION DL, Select All) and Oreo, VS99620a_11_0207_ARB00.kdz so I'm able unlock it, phone call is OK on CDMA network but no data and have not tried a GSM network SIM yet.

NOTE: the phone will likely loop booting and you will have to do the master reset using buttons:

1. Press and hold the Power and Volume down buttons.

2. When the LG logo appears and quickly release the Power button only and press Power button again but keep pressing the Volume down button until you see the screen to select Yes to erase and reset everything.

Chazzmatt, which of the two Patched lgup downloads should I use to Frankenstein my phone from Verizon vs996 to get to nougat, then to Oreo (I am on 8.0, but know that I need to do the process)?

Also, if I do the Frankenstein, but wait to do the actual "wtf" boot loader unlock a few days/weeks, can I still keep the "automatic system updates" off in the developer section? Right now, it is turned off.

I just want to make sure that option is still available in the nougat/Oreo US998 developer options.

I'm not sure why you're posting this Oreo H930DS question in the US998 Nougat KDZ thread... It's not about Nougat, and it's not about US998.

You can't use Uppercut in Oreo. Uninstall Uppercut, reboot PC, install dev patched LGUP. Flash the KDZ you want, in DL PARTITION mode. But it will NOT be this one. ;)

I have a the H930DS.. For the frankenstein method I wanted to confirm if the NOUGAT US998 is mandatory or can it be a NOUGAT INDIA firmware too? Reason I ask is, I'm currently downloading the pre-July v20b firmware from one if the mirros you provided and the download keeps failing. I have to keep manually retrying for the download to continue. I found another link where the IND nougat is available https://lg-firmwares.com/downloads-file/13473/H930DS10f_00_OPEN_ESA_DS_OP_0319.kdz and I was wondering if this would be fine for the Frankenstein method
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You cannot flash any North American variants over H930DS. Do not flash US998 over H930DS. You have read nothing in the Instructions telling to to do that.

Since you mentioned pre July firmware, I assume you really want to unlock your bootloader, install TWRP and root?

Are you confusing Frankenstein with WTF? Most North America variants (except H932) have to use Frankenstein during the WTF instructions, to get fastboot flash commands. But Frankenstein existed already before WTF, to carrier unlock North America phones, like H931 and LS998.

You need to thoroughly read the WTF INSTRUCTIONS.

The H939DS doesn't need Nougat for bootloader unlock and root. Only North American variants TEMPORARILY need US998 Nougat to get to pre-July Oreo.

Frankenstein is used on North America variants to get them fastboot flash commands. H930DS already has fastboot flash commands.

For H930DS, you just need pre-July Oreo firmware to run the WTF exploit. Use either H930DS or H930 pre-July Oreo firmware.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] schizovivek:
From what I've read, I assumed, if anyone is on the post-July firmware (I'm on v20c) we needed to go back to a pre-July firmware (v20b) and for that we would first need to go to Nougat and then back to pre-July for unlocking the bootloader and root.

Apologies for this. I guess I got confused and this I why I wanted to make sure I'm doing the steps right

Based on what you've mentioned does it mean I can load the pre-July firmware directly? Should I be using the "Partition DL" option or "upgrade" will work? (I'm on v20c-IND currently)

I'm very new to flashing on LG phones so please forgive my naivety :angel:
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
This part is correct for everyone, all variants.

This part is not correct for all variants.

The goal stated clearly at the top of the WTF instructions:

1) pre-July Oreo firmware -- for the early Oreo bootloader unlock exploit

2) fastboot flash commands -- to run the exploit and install TWRP.

Of the North American variants, ONLY the US998 has fastboot flash commands. Thus the need to Frankenstein most of them to US998, if they are not that already. (U.S. T-mobile H932 is an island to itself; anything I say in this post do not apply to H932.) And to get most North American variants converted to US998, they have to go through extra stage of US998 Nougat to get to US998 Oreo. LG threw in some code to block most North American non-US998 variants from flashing straight to US998 Oreo. So, the Nougat step is ONLY for North American variants trying to convert to US998, to get fastboot flash commands and pre-July Oreo.

Whereas all the H930 variants -- H930, H930DS, H930D, H930G, etc --- already have fastboot flash commands. ;) It's EASIER for you.

You just need to temporarily downgrade to pre-July Oreo firmware.

But I wrote a

very extensive guide, in in the WTF thread

. You should be following those instructions. They answer all questions. There's even decision tree type stuff -- if you have H930DS you do this, if you have some other variant, then you do that...

You have to read all that thoroughly. I'm only repeating myself here, when it's already typed out THERE.

You would use Partition DL to downgrade to pre-July Oreo firmware for the H930DS.

Is there a TWRP flashable zip of this KDZ somewhere??
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
If you mean US998 Nougat 10c or 10d, no there is not.

We didn't get any TWRP-flashable zips until after a few Oreo updates. [MENTION=3642089]westwood24[/MENTION] graciously provided for Oreo US998 and H930, and [MENTION=3138121]seadersn[/MENTION] and [MENTION=6815443]JohnFawkes[/MENTION] -- and others -- have continued that endeavor.

That's why there's no TWRP zip (and not needed) for US998 20a, b, c. TWRP-flashable zips started with US998 20d.

You CAN flash US998 10c or 10d Nougat with LGUP, install TWRP and root, as long as you already have unlocked bootloader.

But, all Nougat is really good for us just temporary stage for Frankenstein to get to US998 Oreo for bootloader unlock and root. There are so many camera and audio improvements (LG DTS 3D Stereo framework) in stock Oreo.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] teknomedic:
I see, thank you... I saw an app called KDZZ that allowed making TWRP zips from KDZ files and hoped someone had made a US99810C Nougat zip for TWRP.

I'll need to downgrade with LGUP then it seems. Thanks again.

also... do you know if TWRP 3.3.1-0 is available for the V30? I don't see it listed on the TWRP offical page and am too afraid to download another hardware version from the offical app.

Alright I have tried everything in this thread and the others with zero success.

This is what I am trying to do.

I am trying to do a full refurb of my US Cellular US998 LG V30+ so I can relock the bootloader and sell it online. I have recently upgrade my phone due to the whole Verizon CDMA sunset thing and the LG models are going to suck later down the line.

Anyway I can see the phone in LGUP in every mode EXCEPT for download mode.

As soon as it goes into Download Mode, it does not appear in the device manager and subsequently does not proceed to flash because of that.

I have tried manually going into Download Mode (Vol up plus plugging in with cable) Tried different cables, different types of USB ports (USB 2.0, 3.1). Reinstalled the drivers after a full registry clean and device manager hidden devices clean. re-installed all the different versions of LGUP that are posted in this thread and the others...

All do the same thing. Cannot see the phone once its in download mode.

Does ANYONE have any suggestions at all on what to do next?

I mean I CAN just sell it as is, but I would rather it be fully back to factory before I did.

PS. Also not a newbie to this crap either. I was a service Tech at US Cellular for 9 years before they got rid of us all due to them starting to sell Apple devices (They'll tell you its not, but it IS because they didnt want ANYONE repairing those devices and we were all let go mere months after starting to carry it - NOT coincidence). Also still do phone repair on the side from time to time, but this issue has me stumped.
