[LG V30 Guides, News, & Discussion] ChazzMatt:
You're welcome. And while strongly believed buying overstock H931 off eBay was just as good as buying from AT&T (from past experience with friends), AT&T INSISTING to you they were keeping track of H931 V30 IMEIs they sold (or whatever they claimed) and ONLY those were eligible to be provisioned on AT&T for Wi-Fi Calling and other goodies does sound like something AT&T would do. :p

Last year, a friend got a VS996 V30 off eBay for Verizon and everything works fine. It was NEVER sold by Verizon, but on her account everything is provisioned for all the Verizon stuff. I've also had friends buy older AT&T LG G2, LG G3 and everything worked fine on their AT&T accounts. So, I couldn't see why suddenly it would matter if you did or did not actually buy the phone from a carrier -- as long as it was their carrier-branded phone (in this case AT&T branded H931).

But on the other hand it's not my money. So, while I was fairly sure AT&T was lying to you, I had to leave it up to you to decide which way you wanted to go. (My wife and I and several friends/family members use US998 on AT&T, but none of use use Wi-Fi calling.)

Whereas, LG does use IMEI and Device_ID to determine which few phones get bootloader unlock codes. You can't just have a US998, for instance -- it has to be US998 SOLD by an authorized retailer like B&H Photo. Not given away in a promotion, not sold by U.S. Cellular, not Frankensteined to US998. LG does keep a database of eligible IMEI for bootloader unlock codes. I know because I got one, before WTF method (May 2018) instantly made all that nonsense irrelevant. :cool: So, when you told me what AT&T was gaslighting you with, it sounded similar to what LG actually does on their LG Developer website. Luckily, it wasn't true. I didn't think it was, but with control freak carriers, you never know.

I've been on AT&T for years and I've never used an AT&T-branded phone for their service. I use AT&T Prepaid (formerly called GoPhone, which was confusing name) the Bring-Your-Own-Device part of AT&T, sold and serviced in AT&T stores. Same SIM card as AT&T Postpaid (aka contract AT&T), same servers, same data speed, same in-store customer service. Much less price, because you own the phone and are just paying for monthly service. (8GB high speed data/unlimited calls/unlimited messages for $40 per month. I get it for even less because of workarounds I know.)

My sister and brother-in-law have "regular" (postpaid) AT&T, but even they are using US998 V30+ on AT&T -- not AT&T-branded H931. They don't care about Wi-Fi Calling, etc.

Only the AT&T H931 and Canada H933 have AOSP/Lineage custom ROM installation issues. Native US998 and LS998/VS996, AS998 all converted to US998 don't have any issues installing custom ROMs, as well as all the H930 variants. U.S. T-mobile H932 can install AOSP/Lineage ROMs, as longs they are marked for H932.

Yeah, the dev has to hand-build the TWRP-flashable zip. He has to capture the OTA update and then integrate the changes into the current image. It's a quite a task. [MENTION=6815443]JohnFawkes[/MENTION] has to do the same for the Sprint LS998 TWRP-flashable zips. I don't blame them if they skip an update here and there. ;) The last major change was the DTS firmware and this TWRP-flashable zip has that.
