Can this be flashed yet?
[LG V30 Guides, News, & Discussion] techdoctorusa:
no not yet

only firmware dump can be downloaded

h931 30g flashable zip must be created first
[LG V30 Guides, News, & Discussion] mrsubway:
Officially retiring my v30 as a backup phone. Got an LG Velvet. Pretty phone. The beveled edges take getting used to, but Android 10 is sweet. My only issue is THE CLOCK MOVED TO THE LEFT ON THE STATUS BAR IS DRIVING ME NUTS!

I'll have to learn to live without root. I'd rather have accesses to OTA updates anyhow.

download link

I can not find the download link anywhere for TWRP flashable h931 to flash LOS 16
[LG V30 Guides, News, & Discussion] ChazzMatt:
The dev removed Oreo download link in anticipation of a Pie TWRP flashable zip that has not yet been delivered

Luckily you don't need H931 Oreo firmware if your intention is to go to LOS-16. You can flash the US998 20h Oreo TWRP flashable zip... Then install LOS-16.

The only reason people would need H931 stock is if they are:

1) AT&T customers and want all AT&T LTE bands, even the minor ones.

Note: US998 has most of the AT&T LTE bands. I use AT&T with US998 firmware and see no need to have AT&T firmware.

2) Need AT&T firmware for stuff like VoLTE on AT&T network. There are caveats with that. Most users need native H931 for that, but if you already have it enabled in your AT&T account it has worked for others to convert another North American variant to H931.

Yeah the clock thing is due to Google trying to act like Apple instead of staying true to their own design.

new update..
[LG V30 Guides, News, & Discussion] ChazzMatt:
Interesting! At least this 30h, AT&T admits it's 2019 security patch, unlike Verizon who tried to claim their recent update was August 2020 security patch. :rolleyes: It wasn't. It was August 2019 security patch!
[LG V30 Guides, News, & Discussion] 3xper:
exactly

i hope someone can realize a flashable zip for this one if it's possible

[LG V30 Guides, News, & Discussion] cmrntnnr:
This is a heads-up about AT&T and the V30 that seems relevant to this forum. I popped my AT&T sim from my GFI V35 into my open market V30. AT&T suspended sevice immediately on boot up; the phone was flag as non-branded based on its IMEI. The reason for deactivation is that non-braned V30 do not support VoLTE on AT&T. Phase out of the 3G network is being taken as an opportunity to sell new, branded models. I had to speak to an operator from my V35 to have service restored. Sorry for the bad news. Details are in the attachment.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, AT&T are being aggressive about this. They probably won't shut off as long as you are using it but won't let you re-insert if you go to another phone. AT&T just shipped me a "new" phone -- certified refurbished Galaxy Note 9. I have 30 days to switch over or they will deactivate the service on my V30+. I have a carrier unlocked Galaxy S10+ in box, but I was waiting for this "free" phone to keep as a spare. Took them long enough. They had promised me back during the summer. I knew if I switched over to the S10+, they then wouldn't ship me the free phone. I'm actually surprised it's as good as it is. Will probably go to my daughter.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I have H931 20F and 20H.
[LG V30 Guides, News, & Discussion] cmrntnnr:
Hey @ChazzMatt. Absolutely agree with you, they are aggressive. There are so many things wrong with their approach. I don't begrudge them refarming spectrum. Increasing bandwidth should be good for everyone. However, there is no reason a V30 of any badging should not be supported.

Like others have already done, I will be filing a compaint with fcc. It won't do anything but let me fantasize about a day when carriers are banned from selling phones.
[LG V30 Guides, News, & Discussion] kenbo111:
What's the difference between those and 20s
[LG V30 Guides, News, & Discussion] ChazzMatt:
20S would be newer and have more fixes. I know the developer removed all his files, but I have a couple of the older ones is all I was saying.
[LG V30 Guides, News, & Discussion] kenbo111:
So I tried the 20s I found and got boot loops. It's not from the same dev so maybe it just doesn't work. Is it possible to get 20h from you?
[LG V30 Guides, News, & Discussion] spacepirates:
If you search on AndroidFileHost for "H931" you'll find 20H uploaded by ChazzMatt. I know it is publicly listed, but I feel weird posting the link to it directly. If you can't find it, let me know.

I plan on flashing my US998 (that is currently running Verizon's rom) with H931-20S (and maybe 20H if I also get boot loops) so my wife can use it on AT&T. If AT&T checks the IMEI, though, that might not work. Guess we'll find out...
[LG V30 Guides, News, & Discussion] ChazzMatt:
Just sent you a PM. Don't want to post publicly as dev removed his files from this thread. I wish he hadn't as they are still helpful for some people. He did good work and we appreciate that. I wish I had saved some of the later ones.

H931 20H was the first to have DTS framework for the AT&T H931, but DTS wasn't enabled by default. You need root and there's instructions in other thread how to enable it. For other variants, JohnFawkes started flipping the switch to have it already enabled when installed and then so did this AT&T dev in releases after 20h.

=========

03/19/2022 EDIT: Several people are needing this now that AT&T 3G HSPA is shutting down. I've now made a public post. I give full credit to the dev of this thread. See

[LG V30 Guides, News, & Discussion] kenbo111:
So 20h worked. Kinda.

What I was trying to do was get wifi calling to work with Straight talk. They said i needed an ATT phone for it to work. So I just installed 20H and i can make WiFi calls now! But I can't make cell calls now. lol

The phone won't connect to the cell network at all. It does see the sim and sets my phone number correctly. And the APN is correct.

Any settings I can try, or is it back to us998?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Don't know. You now have AT&T firmware so the Wi-Fi calls work. Strange about not connecting to the cell network.... Since it probably flashed the AT&T modem, you should have all the AT&T bands. Even with US998 you have most of them.

Hmmm... I found this earlier in the thread:

Maybe try to re-flash the modem.img in TWRP?

[LG V30 Guides, News, & Discussion] kenbo111:
I installed H again. And installed the modem.img from the zip and everything is working fine. I'm debating whether I should try installing 20s now. But I probably won't due to what happened the last time.

One thing tho, twrp is asking for a password to decript data now. I didn't set one. I just hit cancel and had no problems using it.
[LG V30 Guides, News, & Discussion] postmortem.:
AT&T is whitelisting devices now based on IMEI. If your IMEI shows different model than AT&T V30 variant, you'll be blocked. AT&T ROM won't help you.

[LG V30 Guides, News, & Discussion] ChazzMatt:
This is why I had to move myself, my wife, my mother to different phones. We all had native Open Market US998 and were running them on AT&T. I got them LG V35, where AT&T is accepting both the AT&T version as well as the carrier unlocked Open Market (which was sold by AT&T subsidiary Cricket). For myself, I now have carrier unlocked Galaxy Note 9 (bootloader unlocked and rooted).

All those are 2018 whitelisted phones for AT&T. But for the 2017 V30, only genuine AT&T H931 are whitelisted.
[LG V30 Guides, News, & Discussion] postmortem.:
Yep, unlocked LG V30 and V40 are no longer allowed on their network, but AT&T variants of these do work... still plenty of them in a good condition on eBay
[LG V30 Guides, News, & Discussion] rikita:
So if I get an h931 and unlock and root via WTF it will work on AT&T?

And then I can Frankenstein to US998?
[LG V30 Guides, News, & Discussion] cmrntnnr:
Yes, it should. You'd be better off getting a v35 or G7 though.
[LG V30 Guides, News, & Discussion] rikita:
Thanks for the tip.

Have used v30's for me, wife, my mom and our kids for 3 or 4 years. Me and my mom on AT&T rest on Verizon. When AT&T blacklisted the US998, I bought a couple of Verizon v50's (wanted to try the 5g). Pretty big pain in the arse to unlock, root and install TWRP and they don't seem to be nearly as stable as my v30's. Plus, one of them bricked while my mom was surfing the internet on it last week....just shut down and I cannot get it to power on.

V35 and G7 guides for unlock and TWRP look real similar to the v50. Not sure I want to go to all that trouble again especially with the probability that they might be buggy.
[LG V30 Guides, News, & Discussion] britishchip:
hi i want to install an A12 custom rom on my h931 converted to us998, i've followed all the guides from you and other members to now successfully be on us99830b pie firmware (thank you) now the post about installing roms on converted h931s led me here for a h931 rom and i can't find it, what should i do?( i'm not an at&t user if that helps) also, is there something else i should be looking at since this guide was written during los 16 and los 17 periods and i want to install an A12 rom?
[LG V30 Guides, News, & Discussion] schwinn8:
ATT doesn't release their ROM at all, so you can't get back to that version. US998 will work fine on ATT, the only thing you won't get is updates from ATT, but that's not an issue anymore since there are no more updates for this phone anyway.

If you're not on ATT, then you don't need the ATT ROM anyway... US998 will work there and with other carriers with fewer issues. The only problem you will have is that carriers may check the IMEI and refuse to activate the phone if it doesn't match their expectations. It's not because the phone won't work, it's because they want you to buy a new phone...
[LG V30 Guides, News, & Discussion] ChazzMatt:
This below is ONLY for people on AT&T or AT&T MVNOs who have a native H931, are rooted and wish to return to AT&T firmware so they can get VoLTE and Wi-Fi calling now that AT&T 3G HSPA is being shut down... You will still have TWRP and root. The only V30 on the AT&T whitelist for VoLTE/Wi-Fi calling is the LG H931, which was made for AT&T.

All credit goes to the devs listed. I uploaded these files to my folder for easy access, but I give full credit to the devs.

See posts

#517 - #520

for proof this works. Thanks to @kenbo111 for confirming.

INSTRUCTIONS:

To return to rooted AT&T firmware on native H931, flash the H931 20H zip in TWRP by david.542569.

THEN, flash this modem.img (from H931 20S) extracted by MicroMod777.

In TWRP, on the lower right side you can choose whether to flash .zip file or .img file. The first file is zip, the second is img. (If you don't flash the modem file you will have connectivity issues. Again, see posts

#517 - #520

.)

On native H931 with AT&T IMEI (even if was Frankensteined to something else like US998 for bootloader unlock), you will now have a V30 that is recognized by AT&T for VoLTE and Wi-Fi calling. This result can NOT be be achieved with another North American phone that was not first an original AT&T H931 V30. If you Frankenstein'ed from another V30 to H931, AT&T can still see the non-AT&T IMEI. Your phone will need to have been sold as an AT&T H931, a "native" H931 from the factory, to use this to get AT&T VoLTE and Wi-Fi calling.
[LG V30 Guides, News, & Discussion] surgemanx:
Thanks for this Chazzmatt!But,the imei doesn't even matter with AT&T.It's the authentic firmware is all that's needed.Why?I have no clue?I have been trying to figure out what it sees exactly in the original firmware for it to enable?I currently have a U.S. Cellular V60,and AT&T as my provider.I have even called them and told them the imei multiple times when the March 18th 3g shutdown went in to play.So,I found a luns AT&T 20d copy of the firmware and wrote all files but Luns 5 because of the imei etc.It all works with no hiccups at all.I just can't get the updates is the only thing of course because of the imei.I'm still stabbing at it with my LG Wing Demo too.The good thing about the Wing you can flash any firmware to it as a refurb,and roll.With the Wing I have extracted the mbn's from the modem files,and wrote them in PDC and enabled 5g for the APN to see it.Edited all the APN settings,and still a no go for voice calls?So,the IMEI isn't the issue.
[LG V30 Guides, News, & Discussion] surgemanx:
Anyone else having issues with OTA updates after flashing the H931 20H zip?My issue is OTA updates with no TWRP installed and the bootloader relocked?This zip works excellent, but no updates can be installed?Gives me an error I need to conatct LG Customer support and reboots.
[LG V30 Guides, News, & Discussion] ChazzMatt:
OTA updates are usually predicated on IMEI.
[LG V30 Guides, News, & Discussion] ChazzMatt:
You are saying that even though you don't have V30 AT&T IMEI you ARE still getting VoLTE and Wi-Fi calling on your V30 with an AT&T phone number? Your post says V60, so I'm confused. You also mention LG Wing, which is aslo not V30.

My instructions are only about V30: "The only V30 on the AT&T whitelist for VoLTE/Wi-Fi calling is the LG H931, which was made for AT&T."

Phones made after 2017 have different rules.

What is "luns"? Sorry, doesn't ring a bell. I'm curious. Is that a repository or another forum?

I've not been that active past couple of years due to family stuff, so I apologize for not knowing about that.

Yes, AT&T checks IMEI for OTA updates.
[LG V30 Guides, News, & Discussion] surgemanx:
No,I was speaking about my h931 AT&T branded with the OTA updates.It will download the update,and then give me a 0x00 something error code and tell me to contact LG support.Download mode states modified at the bottom.So,I factory reset it and started fresh.Relocked the bootloader and factory reset in US998 20h.The next write I tried was a Luns backup I made with your h931 20 with a fresh reset and still the same error.I'm thinking when you made the copy yours was rooted at the time,and it picks up on it?My guess on that one?Luns will copy all partions of the device except a few hidden ones of the software that's on the device with the fh_loader in the qualcomm bin folder.You're very correct,it's IMEI specific for the updates.Hell,I'm not complaining at all about your posted back up of the H931 h20.It works like it should fully 100% just won't take OTA updates.And I apologize about the confusing with the V60 and the Wing.But,I crosshed flashed my V60 the same way as a Luns back up,and they have my IMEI number and it's working 100% as well.My main question is what is hiding in the factory firmware that AT&T's servers see that's blocking some of these different carrier devices?My hats off to you again for the back up the firmware.I ordered a junker v30 off Ebay for the main board and was going to swap it out to get the lastest firmware and make a back up copy stock and post it here with last update.I like my V30,it's been one of the best phones I have ever owned.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, the V30 series was one of the best phones ever made. LG just didn't know how to market it or make worthy successors.

Put a little more RAM in and newer processor and I would buy it all over again. I gave my wife and my elderly mother both V35 -- which is the closest thing to an updated V30. 6GM RAM, no notch, slightly faster processor. Even uses same cases.

====

For the H931 backup I provided, all credit goes to the dev of this thread -- david.542569. That's just the most recent of the stock "ROM"s I kept that he made. I wish I had downloaded and saved the very last one (last Oreo). He put a lot of work into them.

Yes, he was rooted and he made them to be flashed with TWRP custom recovery.
[LG V30 Guides, News, & Discussion] namitutonka:
@ChazzMatt Given your notoriety on XDA you probably already know this about a Galaxy Note 9.
[LG V30 Guides, News, & Discussion] wildtek:
Please if I may ask the version of the rom? Pie or oreo
[LG V30 Guides, News, & Discussion] ChazzMatt:
30G would be Pie. For the V30 series, "10" was Nougat, "20" was Oreo, and "30" was Pie. The the alphabet letter after showed the successor. For example, 20A would be first Oreo, 20B would be next, etc. 30 was the Pie ROMs.

Not that it really matters. The H931 (AT&T) dev left and none of his files are posted, EXCEPT the H931 20H (Oreo) I saved and made available a few months ago. Scroll up to post #530.

[LG V30 Guides, News, & Discussion] mrsubway:
Quick questions. I noticed this ROM doesn't have the bootloader unlock warning. Is that because it's an AT&T ROM? Also, can't boot to bootloader. I'm assuming I'd have to go back to us998 to regain Fastboot. Not that I need it right now. Just curious.
[LG V30 Guides, News, & Discussion] Who-Lep:
No problem, I can make a full back up excluding data and efs partition. Let me know if that would help.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes. AT&T and Verizon never expected you to be able to unlock the bootloader, so there's no bootloader unlock warning on their firmware, in raw_resources and raw_resources_bak. ;)

Some others have only flashed those particular paritions in LGUP (while staying on us998) to get rid of the bootloader unlocked warning. But one person bricked their phone doing that (think the versions weren't close enough), so there's a risk.
[LG V30 Guides, News, & Discussion] mrsubway:
I LOVE the warning. LOL! Verizon and AT&T "never expected it." Pardon me as I laugh like the Joker after smoking a pound of weed. ??

---------- Post added at 04:03 PM ---------- Previous post was at 03:58 PM ----------

Just a note. I used a Magisk module to get Lineage sounds and boot logo. Didn't like it, so I removed the module. Sounds went back, but it kept the Lineage boot screen. I don't really care, but when I saw the OP flashable to get the AT&T logo back, I tried in TWRP. It flashed, but the boot logo remained Lineage. What DID work was pulling the BOOTANIMATION files out of the zip and manually placing them and setting permissions. Back to the old boot logos. So, you may want to check the zip. No big deal.

PS: Is there anywhere to get some cool bootanimations?

Hello,

maybe somebody of you can help me. I'm from Germany and bought a H931 at Ebay. Now I've got the problem that I can not do any updates (not OTA, LG UP or LG Bridge) because I allways get the message that my device may be rooted.

Actually i have the H93120c on my phone. The phone was unlocked by the seller. That seems to cause the problem.

Somebody got an idea how to change this? I'm an absolute noob and did never work with TWRP and things like that.

[LG V30 Guides, News, & Discussion] ChazzMatt:
You should convert to us998 and manually flash any KDZ updates you need, via LGUP. This "ROM" is for AT&T customers. You also don't need TWRP to install US998 updates.

SEE the Frankenstein thread for instructions.
[LG V30 Guides, News, & Discussion] cthiessenh:
Thanks for your help. Now i have got the problem that i can not start the developer mode of LGUP. I tryed to do it like you showed in your post but i doesn't work. Uppercut is detected as a virus by windows and gets blocked.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Please don't use Uppercut. Uppercut does not work on Oreo. You only need Dev Patched LGUP.

Uninstall Uppercut.

I purposely removed all references to Uppercut from the KDZ threads. You will not see me even mention Uppercut anywhere, except to tell you not to use it.

( Yes, one picture still shows it, can and Ivwish I could delete that picture! But it demonstrates WHAT to click in LGUP).

Now i have the LGUP developer edition, but i don't know where i have to put the kdz to be shown in LGUP. I put it into "common" but it doesn' appear.

Is this the right way to do the crossflashing:

- Turn of V30

- Push louder button and connect with USB

- open LGUP

- choose Partition DL

- choose the KDZ

- select all

- start

Did anyone do this before in combination H931-20c to US99820e_02_0910 sucessfully?

I have never done something like this bevor, so I'm really scared to brick my phone.
