Since it doesn't involve unlocking the bootloader, it has nothing to do with warranty. It's a method to install the official versions of LG firmware you wish, not the latest they may want to force on you. But it has to be firmware signed to be compatible with your LG V30 variant.

By the way, I'm voiding the warranty on three of my US998 phones as soon as I can.;) One down, two to go.

Hi Everyone

does anyone have the stock firmware for ATT H931?

i desperately need it

thanks
[LG V30 Guides, News, & Discussion] ChazzMatt:
[MENTION=5012130]padmanek[/MENTION], the thread creator can answer better than me, but it seems this should not inhibit OTA updates in any way.

The only official firmware you can flash on our V30 is firmware that is signed by LG for your model. So, all this thread explains how to do would be either downgrading to older official firmware or upgrading to newer official firmware meant for your model.

Even if you unlocked your bootloader, rooted, installed some custom ROM -- this thread explains how you "restore" back to official firmware. It's full, official firmware -- including the OTA update framework.

[MENTION=5012130]padmanek[/MENTION], if any of that is not correct, please clarify.

So, the only time OTA updates would come into play is if you had downgraded back to older firmware for some reason. The OTA notification should still work for the current, newer firmware -- but would be annoying, because you purposefully went back to OLDER firmware. ;) You would have to ignore it as long as you could.

Hi guys.

I can use my LG V30+ 128Gb with V10e-AME-XX, firmware "H930DS11m_00_OPEN_HK_DS_OP_1229.kdz" to have a VoLTE?

Thank you.

Have I made a mistake?

Hey everyone - first time here and new to this (as we all were once).

I have a H930DS and I've flashed it with H930DS10e_00_OPEN_AU_DS_OP_1230.kdz as I'm from Australia. I'm not sure what difference there is between that one and the one released 6 days prior which is H930DS10d_00_OPEN_AU_DS_OP_1124.kdz. I'm assuming the H930DS10e is the better choice based on the increment in letter values? Originally it had a HKG version.

From what I've been reading Oreo is supported for other versions of the V30+ but not yet for this one? Is this correct and if so any ideas why or when Oreo will be made available to me?

Did I make a mistake getting the DS variant even though I'm utilizing both sim slots.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You've read misinformation from somewhere then. If there was Oreo for "other versions" of V30+, the firmware would be posted here in these forums.

No V30/V30+ has Oreo except

LG V30 South Korean carrier models

. That's the

only V30+ that has Oreo.

(That thread was started when it was still beta, but South Korea V30/V30+ got stable Oreo starting end of December. Some people were still getting it in late January.)

Nobody else is going to get Oreo until March, after the South Korean Winter Olympics are over. LG is headquartered in South Korea. Apparently the whole country has taken the month off. :p

A

US998 V30 user is participating in the Oreo beta testing program, so he has a beta version.

When Oreo is actually released for other models, there will be lots of news about it and the KDZ will be posted in this forum.

Here's a screenshot from that US998 Oreo tester.

Can this method be used to change the firmware to stock from ATT's firmware?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Tell me what you mean by "stock" firmware? Do you mean the open market US998 model?

If so, no, you can't flash AT&T H931 V30 to open market US998 V30. You can't change your AT&T H931 to anything else. You CAN flash older AT&T H931 firmware if you wish. (There may be reasons for that, like if someone finds an exploit that works on older firmware.) OR if for some reason your updates are not working, you can flash to newer AT&T H931 firmware you have downloaded.

Hi,

i´m new here ;) ... and sorry about my english ;)

I´m interested in buying a V30+ the version H930G because of the 128 GB and the ability to root it. The only model i found is an italian brandet by TIM. But I would like to have an unbranded V30+. So this thread could be the solution or I mussunderstood something. I checked the firmware on (not allowed to post, because its my first post... i mean the link from lg in the first post of this thread) but I don´t know which one should I use. I need an unbranded firmware that I could use in germany.

Has someone an advise?

And whats after flashing this firmware, does everything work fine, the OTA for example?

Thanks for help.

I've bought an LG V30 H930 (Open EU) model, but it's carrier branded by TIM.

The latest update I've got OTA is 10g, so I want to be able to flash the 11m.

Which firmware should I use (that's compatible ofc), that will get rid of the carrier bull****, including the boot animation?
[LG V30 Guides, News, & Discussion] Sean473:
Use the Open EU H930 11m kdz.. That should sort you out.
[LG V30 Guides, News, & Discussion] Arcide:
Does it matter which one? Cause on the LG website there are different kdz files for the same version and with the same name (open EU), the difference being the localization.

Some of them are Northern EU, Poland, Italy, France etc, and some of them just say IBR, ITC or similar.

Is there like a one-for-all firmware I should use?

Would this affect my network in any way (I'm from none of these given locations btw)?

Sorry for the stupid question, but even though I'm experienced in flashing a ton of roms, this is a bit sketchy for me.

[LG V30 Guides, News, & Discussion] ChazzMatt:
The firmware I posted is for LG H930, which is also compatible with H930G and has also worked for many people on H930DS.

But for H930DS, it does depend if you use your dual SIM slots or how you use them. Many in India for instance, just have that model because it's what's available. They don't actually use dual SIMs. Or they have one for data and another for phone calls.

IF you are actively using the slots for data and phone calls on both, see this thread and ask there if that situation fits yours.

which kdz to get?

on this site https://lg-firmwares.com/lg-us998-firmwares/

the region says UCL for the file i believe i need. according the the region description documen, that means "US Cellular" but my device is not US Cellular, it's the carrier-unlocked version

also.... the OP says the bootloader doesn't have to be unlocked...but does that mean it is ok if it IS unlocked?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You have the open market LG US998?

10D is the latest right now, but it's not Oreo.

All US998 can flash all US998 KDZ, whether U.S.Cellular model or the open market LG US998. The only difference is IMEI range on the LG Developer Bootloader Unlock list website.

The U.S.Cellular model is the "unofficial" carrier unlocked model. ;)

I own three open market LG US998 V30 and V30+.

Here's the latest KDZ.

https://xdaforums.com/showthread.php?t=3736910

The problem is you have to temporarily lock your bootloader again to flash this... You sure you want to do all that just for a Nougat security update?

[LG V30 Guides, News, & Discussion] glhelinski:
thanks for the informative post! yes, i have the open market us998 (i used a different term cuz i couldn't think of open market)

not interested in security update. what i was attempting to do was a factory reset (was wanting to do the built in stock way but I put twrp on it so i didn't think it would work).

was wanting to do a factory reset because the device has a screen defect (vertical line thru the entire screen...visible on lighter colored screens). i just got the phone 2 days ago. i ended up just cleaning up as best i could and doing an RMA. Yep, the bootloader was unlocked. I have eye troubles so at first i blamed it on that but not the case. We'll see if I have any troubles with the RMA with the unlocked bootloader....hope not. I could probably live with the vertical line but was afraid it would get worse.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Good luck on that. Maybe you'll beat LG's paperwork on the bootloader unlock.

thanks. I just left it unlocked when i returned it. maybe B&H won't notice or care. i had read something about going into settings and switching off "oem unlock" or whatever the setting was....but decided to take my chances...figuring the boot screen would still say it's unlocked. at worst i get it back with a line running up the middle

I have a strange question

Got LS998 (Sprint v30+) from ebay and bought unlock service to unlock for international usage.

Now phone says model number is LG-US998 (US cellular I guess?). It's on 7.0

Once I tried to unlock bootloader from LG, phone was still identified as LS998 on their site. (by IMEI I guess)

So can I use this method to update phone to Oreo?

And if yes, should I use LS998 kdz or US998?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You would use US998 KDZ, for two reasons.

1) If you used LS998 Oreo, you would be back to carrier-locked Sprint LS998.

2) There's no Oreo KDZ available publicly (at this point in time) for Sprint LS998. Only the OTA is available. Same with AT&T V30 H931.

But really, it's #1. With US998 you now have a carrier unlocked phone.

I just converted an LS998 Oreo V30+ to US998 V30+ Oreo. See the F

rankenstein phone thread.

I had to flash a middle stage of US998 Nougat for it to work, but then I used LGUP "upgrade to get it back to Oreo. Sounds like they just left you at Nougat, or you got your phone before Oreo US998 was released.

The only difference from the instructions in the op in this thread to upgrade from Nougat US998 to Oreo US998 on the LS998 V30+ was I had to manually go into download mode (power off, volume down plus power button). Then LGUP saw my former LS998 phone, which is now US998. In Download mode it still said LS998 with Nougat USS998(10D) upgrading to Oreo US998(20a). Final result is US998 Oreo.

[LG V30 Guides, News, & Discussion] ChazzMatt:
Yeah, Sprint may be like AT&T -- only OTA updates? No actual firmware released? That link was for people converting from LS998 to AS998 (U.S. regional CDMA/LTE carriers) to get Oreo. The firmware is very similar to US998 but no fastboot commands.

Well [MENTION=2732656]JWnSC[/MENTION] has a lot of the files. He may have a complete dump, not sure.

But why would you want to go back to stock locked down LS998? And lose unlocked bootloader TWRP and root? Ability to add/edit APN?

Carrier unlocked US998 is more versatile with better resale value than LS998 -- and with [MENTION=2732656]JWnSC[/MENTION] files you can add back LTE bands 26 and 41.

Even with the Verizon VS996, those users are adding back Verizon Wi-Fi calling and VoLTE, but they're not re-flashing full VS996 firmware.

But again [MENTION=2732656]JWnSC[/MENTION] has a lot or maybe all the Sprint files. I've suggested he start his own Sprint dedicated thread so everything is not scattered throughout different threads.

I have an LG V30 H933, basically device has been downgraded from Oreo to Nougat, bootloader was unlocked, TWRP was flashed. I'm able to get the device to launch to TWRP, but not to OS, custom or otherwise. As soon as I turn it on it shows 'Your device software cannot be checked for corruption. Lock the bootloader'. I'm not able to get it to boot into download mode, or anything other than TWRP. The fact that it's in TWRP seems good to be, but how would I go about restoring the stock software? I'm assuming I can't simply flash the kdz from TWRP itself, I need LG's software to use their kdz files, and I need download mode to do that. How do I get download mode back? If I'm able to just lock the bootloader would that fix the issue?

Read the instructions CAREDULLY in

post #193 of the WTF thread

. Especially the link for the

Frankenstein thread, the instructions there are VERY IMPORTANT for your H933 model.

You need to be on Oreo US998 and Canadian H933 has to flash that via DL partition in LGUP, just like when you went to Nougat. That's different from the other variants.

And no you won't restore stock firmware if you want to keep custom recovery and root.

You can't use Uppercut on Oreo. You need dev patched LGUP.

Go to the Frankenstein thread and read that. You can go back to VS996. Many people have done it once bootloader unlocked and rooted. They go back to VS996 via dev patched LGUP with DL PARTITION method, but don't flash recovery partition so they keep TWRP and root.

Go into Download mode manually first before connecting phone to dev patched LGUP.

If you don't care about TWRP recovery and root (assuming you unlocked your bootloader and have those), then use dev patched DL Partition Method and flash all partitions from US998 to VS998 Oreo KDZ.

In the longer form of the instructions I clearly explain flashing US998 Nougat, while very necessary, is also very unstable and you need to do this Master Reset.
