I can probably update to latest if I flash stock recovery. Just like I did to make Sprint’s 30a rom. But it possibly looks for ATT cellular to trigger the update pull. I guess I’ll find out tomorrow when I activate Cricket Wireless.
[LG V30 Guides, News, & Discussion] ChazzMatt:
When Pie comes for AT&T H931, if the dev of this thread does not update for Pie TWRP-flashable zips, you could create a new thread and take over the project. AT&T H931 users who are AT&T customers and want those features (like Wi-Fi calling, VoLTE) would appreciate that.

Hopefully the dev of this thread DOES continue, but if he doesn't, please consider that. You would just start a new thread. You already have some practice with the Sprint LS998, which also does not have publicly released KDZ.

___________

For the AT&T H931 V30, I do not know if Cricket SIM card will trigger updates for full stock firmware.

For some LG models like the V35 (successor to the V30), only an AT&T SIM card or AT&T MNVO Red Pocket SIM card will trigger OTA updates. Cricket SIM card will NOT. Yes, even though they are owned by AT&T. Red Pocket MVNO is treated better by AT&T than Cricket in that regard, and Red Pocket even has lower ping speeds (less lag) on AT&T network than Cricket. The AT&T updates for the AT&T LG V35 has been discussed thoroughly over in the LG V35 thread. (I also own an LG V35.)

For the AT&T LG V35 -- since "AT&T" (Postpaid, Contract) and "AT&T Prepaid" use the exact same SIM card, because AT&T Prepaid is still actual AT&T -- people have bought AT&T Prepaid SIM cards online (not even activated), stuck it in their "carrier unlocked" LG AT&T V35 phones and they then started receiving updates over Wi-Fi. After the update, then they put back in their actual carrier SIM card.

(To reiterate only the outside label is sometimes different for AT&T Prepaid SIM card. Underneath it's still exact same AT&T SIM card and if you switch from AT&T Postpaid to AT&T Prepaid side you don't even remove the SIM card from your phone; it's just an accounting difference. Most of the time, in the store they just give you the "AT&T" labelled SIM card, which is free in any corporate AT&T store. However, franchise AT&T stores will charge you money for an AT&T SIM card.)
[LG V30 Guides, News, & Discussion] MicroMod777:
Well I do have an ATT sim, not activated. So theoretically I can stick it it, and it will trigger OTA?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Theoretically, yes. For some V35 users it took an hour or so, others got notification faster.

Hope it works on V30 like that.
[LG V30 Guides, News, & Discussion] MicroMod777:
Sweet. Will try it tonight and see what happens. :good:
[LG V30 Guides, News, & Discussion] MicroMod777:
Well it looks like Cricket doesn't trigger OTA update, nor did putting in a non-active ATT sim.

Anybody with ATT willing to help get us with the newest OTA? I can tell you what to do.

Did AT&T get Pie yet? I just read that LG has begun rolling out Pie for the V30 for the twelfth time! ?

Not yet.
[LG V30 Guides, News, & Discussion] MicroMod777:
Well just ordered a Red Pocket sim for $10. Let's hope that triggers the OTA on V30.

Copy the package to your device as either /storage/sdcard0/SoftwareUpdate/dlpkgfile.up or /storage/external_SD/SoftwareUpdate/dlpkgfile.up (technically, the filename can vary as long as it ends in the .up extension and is in one of those two locations) in FOTA menu from the Hidden Menu. From here, click on the "Select Package" option, and then choose "dlpkgfile.up" from the list. Once you've selected the update package, choose the "Do update" option from the menu.Than validate & reset

Ignore this. This is for devs who are trying to make TWRP flashable zips.

If you have TWRP installed and try to install OTA, it will mess up your phone.
[LG V30 Guides, News, & Discussion] MicroMod777:
Don't try this. I'm trying to make a factory restore flashable zip to then be able to take OTA.
[LG V30 Guides, News, & Discussion] MicroMod777:
Well just killed my v30. lol. I built a factory restore from a dump and then it got google FRP locked. So then I did a chip erase in LGUP, then Partition DL to US998 and now it only reboots to fastboot. I then flashed twrp in fastboop, flash any rom and either reboots or goes into fastboot. Trying Partition DL one last time.

Any ideas to recover?
[LG V30 Guides, News, & Discussion] david.542569:
Yes had same problem I used Canadian version h933 kdz

[LG V30 Guides, News, & Discussion] MicroMod777:
Interesting. You have link to that Canadian H933.kdz?

ChazzMatt, do you know if that Canadian kdz is flashable on the VS996 Verizon V30?
[LG V30 Guides, News, & Discussion] ChazzMatt:
All North American variants KDZ are compatible with all other North American KDZ -- EXCEPT for T-Mobile H932.

That's the whole point of Frankenstein.

The only caveat with Canada H931 is you need to Partition DL all partitions at both Nougat and Oreo stages (at least going to US998), with Master Reset in between.

Maybe Refurbish works as well, I don't know.

US998 with AT&T H931-20H Rom (Prepaid ATT). I can't get wifi calling working. I put my sim into my co-worker ATT phoen XR. Activate wifi calling. It worked. Then put the sim card back to my phone, and able to activate wifi calling. After 1 min, wifi calling disable, and can't activate again.

Called CS, the guy told me that I need ATT branded phone and IMEI number in order to get wifi calling. They know i don't have att-branded phone by the IMEI number.

So nobody can get wifi calling on non-ATT branded phone?

[MENTION=9236324]david.542569[/MENTION], thanks for this. Just added it to the WTF instructions for AT&T customers, since I had similar for the Verizon customers to flash their firmware back.
[LG V30 Guides, News, & Discussion] mrsubway:
I'm interested to know what's in here that allows the WIFI calling. I'm guessing it's something in the modem. Even the LTE calling is cleaner. The carriers must do something funky to the ROM. They obviously don't care about root or safety net, because I'm rooted with Xposed and wifi calling is fine. Yet even US998 unrooted won't work. I guess it's the "use our crap or lose features" mentality. Interestingly, TWRP formats the SD as FAT32. My feeling is ExFat is problematic.
[LG V30 Guides, News, & Discussion] mrsubway:
Just a note. You should freeze SOFTWARE UPDATE in an app like Titanium Backup. AT&T is trying to drop an update. No worries, you'll reboot into TWRP and it'll go nowhere. But it will keep bothering you and trying to reboot. So, go into airplane mode, and freeze SOFTWARE UPDATE. Other than that, ROM is good. It's basically US998 once you nuke the AT&T bloat. Actually it's running a bit smoother. You can root it and Xpose it. I'm currently wondering if there's a way to set up a dual boot on this phone. I'm wondering if it's possible to partition the internal memory to boot with a H931 ROM or a US998 ROM. I don't travel, so as long as I'm on AT&T, I'll rock the H931. Unlocked bootloader makes me a God. ? Thank you OP. Great job. Maybe that updater apk can be yanked out of future releases. GREAT job though!

---------- Post added at 06:01 AM ---------- Previous post was at 05:44 AM ----------

Yup. If your bootloader is unlocked, you can go back and forth at will. Back up your SD card first. I had an issue where I had to reformat my SD card in TWRP. I'm positive this has NOTHING to do with this zip, but with the AT&T ROM itself. The data on the card was fine on us998, but this ROM required me to reformat the card with FAT32 in TWRP.
[LG V30 Guides, News, & Discussion] mrsubway:
For everyone asking.
[LG V30 Guides, News, & Discussion] N4cr2k:
Has anyone found a way to get WiFi calling on the US998 without having to flash the full AT&T ROM? Right now seems like the only way is to flash this ROM and do some de-bloating/freezing/tweaking.
[LG V30 Guides, News, & Discussion] sguerra923:
I haven't updated yet doing it in the next day or so but can you post your steps? I have some people that PMed me but I think some ATT people want to make sure they get a "clean" install with magisk etc.
[LG V30 Guides, News, & Discussion] mrsubway:
Backup your external SD. It could have been a quirk with just my phone, but the card was unreadable in the phone after I installed this. The card WAS fine, it's just the ROM thought is was corrupt. Then, boot into TWRP, making sure you have this ZIP AND the latest Magisk 17.3. You may want to have all your apps backed up, because you're going to be wiping data. Use TWRP or Titanium Backup, or just restore from Google. Whichever. Do a standard wipe in TWRP. That's all you need. I'm assuming your data has been unencrypted. If not, you'll want to format data in TWRP. If it's unencrypted, nevermind. Now, simply just flash the ROM and wait. The phone will appear to freeze. Just wait. When it's done, do NOT reboot. Flash Magisk first, then reboot system and viola! IF your external became unreadable, you won't be able to format it in the ROM. You'll get an error. Boot into TWRP and format external storage. It will erase your card, and change the file system on the card to FAT32, which I actually like. The ROM will pick it up when you reboot. ExFat seems to be problematic. You're all set. If you want to ever go back to US998, simply repeat the above steps, but flash the US998 20E ROM instead! Have fun!

Almost forgot. Soon after installing, AT&T tried to drop an update. The phone just booted to TWRP because the update issues a command to boot into stock recovery. Nothing happens because TWRP can't use the file. I simply froze the updater in Titanium Backup. A few annoyances, but I like my wifi calling. I'm also convinced the LTE is better on the AT&T network. Wouldn't shock me if their towers somehow prioritize stock phones. Don't mind me though. I'm a conspiracy theorist. ?
[LG V30 Guides, News, & Discussion] mrsubway:
ANOTHER note. Sorry to keep posting, but I found another anomaly, and further proof AT&T is doing something to unbranded phones. On US998, I was no longer getting emergency texts. Amber alerts, alerts from the retarded President, etc, even though they were turned on. Since switching back to H931, I get alerts again. Really nice. So, if you're unbranded you just sit with your finger in you're you know what while the nukes fall. WTF AT&T?
[LG V30 Guides, News, & Discussion] ChazzMatt:
I got Amber alert yesterday on my US998 V30+, and I use AT&T Prepaid. I also got the "Presidential" alert back in October.

Just out of curiosity, I'm about to flash through TWRP and I was reading the OP.. Is it required to have the lastest TWRP installed? I'm still on a 3.2.1
[LG V30 Guides, News, & Discussion] mrsubway:
Do I think you need the latest? No. Should work. BUT, I'd get the latest to be safe. You can flash it in twrp itself. Download newest twrp, boot to twrp, go to install, select image file, find newest twrp file, flash TO RECOVERY, tell twrp to reboot into recovery and check that it took. Always better to be safe than sorry.

3. Re-download the zip and retry. You'd be surprised how often it's a corrupted download.

4. Format the data partition. Not wipe. Format.

5. Wipe system. (This will make your phone unbootable until you flash a Rom.)

Thanks!
[LG V30 Guides, News, & Discussion] ChazzMatt:
Because being in total control of your phone is too great? I don't understand.

Forget trying to revert back to H931 and relock bootloader. AT&T like Sprint doesn't release public KDZ. If there6 a way, I've never heard it here in the forum (due to lack of KDZ).

Best way is to convert back to US998, flash full US998 KDZ, relock bootloader. But you'll still have US998, which you can sell if that's your intent.

OR if you're keeping the phone, you can flash this H931 zip and have rooted H931 firmware with TWRP.
[LG V30 Guides, News, & Discussion] MicroMod777:
So I did a test on my Verizon VS996 LG V30 and flashed an older software, H931 20I that I pulled a dump from my newly received used AT&T LG V30. I could NOT get wifi calling and OTA's to work. So it looks like AT&T's servers check your IMEI to see if they are official ATT phones. If not, you'll get blocked from these two services. Hope this post helps anybody in the future that Frankensteined over to AT&T software.
