Please read the Frankenstein instructions thoroughly. ;) You have to flash from H931 to US998 Nougat first, do a Master Reset, THEN flash from US998 Nougat to US998 Oreo.

Put the KDZs (plural), wherever you want. Use the 3 dot menu in LGUP to locate the one you want to flash for each stage. See the screenshots and especially the instructions in this post:

FRANKENSTEIN - CONVERTING ANY NORTH AMERICA V30/V30+ (except T-mobile H932) TO US998 OREO

Sorry about this being off topic. Does anyone know a way to get weather on the lockscreen? Haven't been able to do it with this or US998. I use a pin lock with all notifications visible. I have a weather widget.

I live in mexico here the lg h931 does not allow to update someone can give me any download link of the h93120c.kdz original please or h93120f.kdz
[LG V30 Guides, News, & Discussion] ChazzMatt:
There is no KDZ. THAT'S the entire point. AT&T does not release KDZ and does not give updates to non-customers.

You need to convert your H931 to carrier unlocked variant like US998, then you can use US998 KDZ for update. See the Frankenstein instructions.

____

This thread is for people who have done that, unlocked their bootloader, installed TWRP, and now want to convert back to H931 because they are AT&T customers.. The thread maintainer created this ROM from raw dump on his phone.

You do not need to do all that just for updates. Just convert to US998 and you can update at will, using US998 KDZ -- even with bootloader locked phone.
[LG V30 Guides, News, & Discussion] mrsubway:
If you use this, updates are already nuked because you'd be using a custom recovery. Plus, I can tell you that AT&T is sloooow to drop updates. I'm ONLY using this because it can be debloated, and I like Wi-Fi calling. I'm sure that, if AT&T updates, someone will make a zip of it at some point. Unless it's 8.1 or Pie, all the updates are pretty minor anyhow. If someone figures out a way to get US998 to use Wi-Fi calling on AT&T, I'll drop this ROM. AT&T are d**ks.
[LG V30 Guides, News, & Discussion] LOBOMANS:
i have the lg h931 but i have tried to enter the page of attt usa and i have not been able to download the updates you have the original h93120c.kdz to update my cel with upercut please here in mexico it is impossible for that i rest to you
[LG V30 Guides, News, & Discussion] ChazzMatt:
1) Uppercut does not work with Oreo. Uninstall it. Install Dev Patched LGUP found in post #1 of US998 KDZ thread.

https://xdaforums.com/lg-v30/development/us998-lg-v30-us998-us99820a040330-kdz-t3786337

2) I've already told you the answer about updates for your phone. You need to convert your H931 to US998, THEN you can install US998 KDZ. You do not need AT&T firmware if you're not an AT&T customer.. Especially if you're living in another country.
[LG V30 Guides, News, & Discussion] N4cr2k:
FYI,

I have a US998 that I flashed with this H931 ROM. WiFi calling didn't work out of the box. I get an error ESD0008 when I try to enable it and a message to call the AT&T customer service number. I tried to call AT&T and see if they could help. After I got past the first line help desk the technician was very helpful and did everything she could to try to enable the necessary features to my plan to allow WiFi calling. But for whatever reason the system wasn't allowing her to save the changes. She gave up, but said she'll ask around. Anyone else have success in getting WiFi calling to work with AT&T on a non branded phone. She even said that it usually isn't a problem to enable the feature on unlocked phones.
[LG V30 Guides, News, & Discussion] mrsubway:
Worked for me. Try getting your SIM card replaced.
[LG V30 Guides, News, & Discussion] N4cr2k:
The SIM is brand new. I had to get a new micro sim when I got the phone. But I may try and go to the AT&T store and see if that works.
[LG V30 Guides, News, & Discussion] Malnilion:
Your V30 IMEI isn't in their database, so probably the only way to get this to work would be to have it working with your SIM on an actual AT&T phone and then transfer your SIM to your cross flashed V30. No guarantee that'll work, though. I ran into the same thing when I cross flashed my unlocked, unbranded Galaxy S9 and never got it working. AT&T are pricks.
[LG V30 Guides, News, & Discussion] mrsubway:
How dare you say that about at&t! ?????
[LG V30 Guides, News, & Discussion] N4cr2k:
So I got it working. To close the loop if anyone else runs into this I had to put my SIM in a branded AT&T phone and toggle on the HD Voice/Enhanced LTE Services. I put the SIM back in my V30 and turned on WiFi calling and it registered and set it up flawlessly. We'll see if it sticks, but it survived a reboot and worked when I tested it. The phone I used was just a cheapo pre-paid samsung galaxy J3 phone that didn't even have wifi calling. But it seemed to be enough to provision my account on the back-end with the necessary features to let it register.
[LG V30 Guides, News, & Discussion] Malnilion:
Wonderful! Glad you got it working! This almost makes me want to cross flash my H931 on US998 20F back over to the H931 firmware, provision my SIM and then get my S9 on the AT&T firmware and see if it works lol. Maybe I'll do it when the AT&T S9 Pie drops ?
[LG V30 Guides, News, & Discussion] N4cr2k:
Spoke too soon. It lasted a few minutes then disabled itself. AT&T goes to great lengths to make sure BYOD phones have a second class citizen experience.

Can i flash this rom in h930ds

---------- Post added at 11:28 AM ---------- Previous post was at 11:27 AM ----------

Can i flash this rom in h930 ds indian
[LG V30 Guides, News, & Discussion] ChazzMatt:
Probably not, as it's stock North America AT&T H931 firmware in TWRP flashable zip file. IF it even worked for you to install without bricking phone on H930DS, it would carrier lock your phone to U.S. AT&T network. The only people who can use this ROM are AT&T network users (AT&T and affiliated (MVNOs) with either original H931 or other compatible North America variants. This also excludes T-Mobile H932 from using this "ROM".

For H930DS, you can flash H930 stock-based ROMs like Boombox or AOSP/Lineage-based custom ROMs. You can also flash H930/H930DS TWRP flashable zip stock firmware based on stock KDZ. You have plenty of choices!

For H930DS, you should stay away from any North America stock firmware.
[LG V30 Guides, News, & Discussion] ChazzMatt:
This is a direct quote from the WTF Instructions (which I wrote):

"Do NOT crossflash any North America variants like US998 with H930/H930DS. "

So, I hope that settles it. OK? No need to keep going from thread to thread asking the same question. ;)
[LG V30 Guides, News, & Discussion] sankhauaa:
Hummm i already told that i successfully flashed 20f rom. Rom is working only for 30 sec to 1 min then shut down. I discover partion size is different.So i cant flash or restore 930ds.So sim card is not detecting.I want to from any body why phone shut down after 30 sec?? Or how i flash 930ds modem in this 20f
[LG V30 Guides, News, & Discussion] ChazzMatt:
You didn't "successfully" flash it if it shut down in 30 seconds and the modem won't work.

No one over the past year has been able to flash H930S or even H930 to North America variants. They're not compatible. I even warned in the WTF INSTRUCTIONS.

[MENTION=6158380]TxanMoe[/MENTION] permanently bricked his phone trying to go from former AT&T H931 to H930DS. He had earlier bricked his phone trying to flash to UD998 then to European H930, and [MENTION=3167089]runningnak3d[/MENTION] helped him recover the first time -- which led to discovery of WTF exploit. Then he permanently bricked his phone trying to help H930DS users.

[LG V30 Guides, News, & Discussion] mrsubway:
Download zip again. Go to TWRP. Wipe cache, dalvik/art, data AND system. Flash the zip. Don't reboot! Flash Magisk 18. It may fail. Flash again. It should succeed. Reboot. SD card is fine. YOU WILL LOSE EVERYTHING IF YOU TELL THE PHONE TO FORMAT IT! Put it in a reader, back up your data on your PC. Format the card with FAT32. There is a tool out there for Windows called GUIFORMAT if you have issues. Copy data back to SD card. Fat32 works between US998 and H931. H931 doesn't like ExFat for some reason. If you don't have an SD card reader, boot to Twrp, plug phone into PC, click mount, and click USB storage. Windows should now see the card and you can copy and reformat.
[LG V30 Guides, News, & Discussion] ChazzMatt:
He has India H930DS and he's not an AT&T customer, so it's not going to work.

If it does work, then he's carrier locked to AT&T.

Actually i want 2 flash 20f for dolbydts.

But no effect when dolby on. Cant understand it is the effect of dts lib present in 20c rom or that sound mod.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Because it's not just the .so file, libs. There's kernel stuff too. Just wait for the next H930DS update, or H930 update.

Can i just flash us998 abl partition which is used to run fastboot
[LG V30 Guides, News, & Discussion] ChazzMatt:
Normally we Frankenstein H931 to US998 to get fastboot flash commands, as you know. How to get fastboot flash commands when converted back to H931 is something [MENTION=3167089]runningnak3d[/MENTION], [MENTION=3475147]SGCMarkus[/MENTION] or [MENTION=6815443]JohnFawkes[/MENTION] could tell you, if it's possible.
[LG V30 Guides, News, & Discussion] runningnak3d:
You definitely DO NOT want to flash just abl from the US998 without flashing xbl -- that will brick your phone.

Even if you flash xbl and abl from US998, you may have a phone that boots, but it will probably have weird issues. You really need to flash the entire bootstack from the US998, then keep modem, boot and system from the H931.

Again, you can try it -- but if you do, flash both xbl and abl (you can ignore the *bak partitions because they aren't used unless you have a firehose and can change the boot LUN).

OTA/93120m

This caught my attention - I got mine rooted using the WTF method yesterday (thanks again to everyone who worked on it!) but there's no Software Update option available in Settings. Is there supposed to be? Is there a way to re-enable them? Sorry if I'm asking dumb questions.

Also, my husband has another H931 completely stock ('cause they were BOGO), which I may root. But before I do, would it be helpful at all to pull any of the current H933120m files from it in the context of this thread? And if so, can anyone tell me how to do so without wasting a ton of your time?
[LG V30 Guides, News, & Discussion] ChazzMatt:
You'll update by flashing via TWRP newer versions of this stock based firmware, when they become available.

There's also TWRP flashable US998 zips based on latest KDZ. Where this ROM has advantages is for AT&T customers.

Here is link to interesting info on ota updates

On lg vs98523a verizion

https://dev.bettermobileapp.com/article/11926510/VS98523A+OTA+Release

cache/fota/dlpkgfile The package is in an odd format and it is rather difficult to extract files from it, as many of the updates are provided in diff patches. However, there is simple way to apply this OTA using VerizonHiddenMenu

Root access is required to run the VerizonHiddenMenu activity

Copy the package to your device as either /storage/sdcard0/SoftwareUpdate/23A.up or /storage/external_SD/SoftwareUpdate/23A.up (technically, the filename can vary as long as it ends in the .up extension and is one of those two locations). Run the following command: Code:

adb shell su -c "am start -n com.lge.VerizonHiddenMenu/.fota.DmcTestFotaMenu"

This will start the diagnostic FOTA menu from the Verizon Hidden Menu. From here, click on the "Select Package" option, and then choose "23A.up" from the list. Once you've selected the update package, choose the "Do update" option from the menu. This should apply the update and if all goes well, you'll wake up with 23A when it's all done.
