Thnx. Chazzmatt.
That is so obvious. How in the world did I miss that?

For whatever reason, attempting to download latest firmware of Nougat for Frankenstein method results in an error. I've failed to download it multiple times. There any other mirrors? This is the only download doing this. Others seem to work. Does it matter which one I use anyway, if I'm just flashing to Oreo anyway?

No, doesn't matter which Nougat, 10C or 10D.

However, if you really want to experiment, try a different browser? It shouldn't matter whether Chrome, Firefox or Internet Explorer, but sometines things are quirky.

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.

Does the patched lg up have all the necessary software upgrades?

 

[ChazzMatt]

Does the patched lg up have all the necessary software upgrades?

Everyone uses it. Yes. It works on both Nougat and Oreo. You want the one that says patched LGUP. This is the Nougat US998 thread but it's the same dev patched LGUP I posted over in Oreo US998.

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

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.

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:

This part is correct for everyone, all variants.

and for that we would first need to go to Nougat and then back to pre-July for unlocking the bootloader and root.

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.

I'm very new to flashing on LG phones so please forgive my naivety

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.

Thank you! Appreciate your help and apologies for making you repeat. was an honest mistake/miss at my end

Is there a TWRP flashable zip of this KDZ somewhere??

 

[ChazzMatt]

Is there a TWRP flashable zip of this KDZ somewhere??

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. @westwood24 graciously provided for Oreo US998 and H930, and @seadersn and @JohnFawkes -- 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.

 

[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.

After going to Beta Pie in US998, you'll need to KDZ to nougat 10d and then KDZ 20H before installing TWRP to allow flashing of custom roms.

 

[ChazzMatt]

No, do not use the TWRP app.

We have UNofficial TWRP, which doesn't mean anything except our dev doesn't have time to jump through all the official hoops.

He tried creating 3.3 for use, and there's a buggy beta for it, but he says to please continue using 3.2.3.7 STABLE -- same version linked in the WTF instructions.

It works fine with Pie.

hi, i followed the instructions but it doesnt works on my H931... I got the error message :

ERROR: 0x4, Not support cross model download H931 to US998

. any idea guys...?

EDIT: its ok it worked !

 

[Cythrawl]

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.
