[LG V30 Guides, News, & Discussion] ChazzMatt:
EDIT: Do in whatever order the Dev says.

The T-mobile H932 is the only V30 where the bootloader can be simply unlocked through the Enable OEM Unlock button and the ADB command.

But in return, T-mobile/LG crippled almost all the fastboot flash commands on the T-mobile H932. It is the hardest of all the V30 variants to root.

Before installing a "ROM" (I assume you mean custom LOS-based ROM?) you need to be back on newer stock LG firmware. This is the major mistake people make on T-mobile H932. They install TWRP on Nougat, then immediately try to install latest LOS-16/LOS-17 ROM. You need the newer blobs (drivers).

There are TWRP-flashable zips (basically stock firmware ROMs) by devs to help you update back to newer firmware. For the T-mobile H932 the latest ones are by [MENTION=9374982]weakNPCdotCom[/MENTION]. You would install these after successfully installing TWRP. This is important step before installing custom ROMs. READ the installation notes and warnings carefully. In some cases he made versions which keep TWRP and some which don't. You want to keep TWRP, of course. Don't be in a hurry!

These are the T-mobile H932 TWRP-flashable zips for last LG stock Pie and LG stock Oreo:

* [STOCK][H932][30d][Pie] T-Mobile LG V30 Stock Collection

Be sure to read

post #5 of that thread

before installing. You especially want the newer versions of dm-noverity-opt-encrypt, and rctd remover.

* [STOCK][H932][20s][Oreo] T-Mobile LG V30 Stock Collection (Includes Debloated)

You need to have stock LG Pie blobs (drivers) installed for LOS-17 Android 10 ROMs and need to have stock LG last Oreo drivers (blobs) installed for LOS-16 Pie ROMs (which is still being kept up to date).

That part is not new, but what is new as of six weeks ago is T-mobile H932 users can now use some LOS-17 ROMs.

Thanks to [MENTION=2022267]ShapeShifter499[/MENTION], T-mobile H932 users can use actual LOS-17 ROM as well as any LOS-17 based ROMs (like Havoc) which have updated since October 3, 2020.

Use this thread for T-mobile H932 compatible LOS-16 and LOS-17.1:

There is a Havoc thread, but the current maintainer only posts to it, has not created a new XDA thread himself. So, it's a little confusing. The previous maintainer has tried to still keep the post #1 updated, but you shouldn't take that as gospel. Look through the last few pages for current developments, like

this Wi-Fi fix

if you need it.

[ROM][UN-Official] Havoc-OS-3.9 [10.0][V30]

For Havoc, you want 3.9 or later for T-mobile H932:

Again, only recently has T-mobile H932 been compatible with any LOS-17 based ROMs. There's still sections of my

V30 Bootloader Unlock and Root FAQ

(Questions #1 and #4, specifically) which states T-mobile H932 is NOT compatible with LOS-17 ROMs and I need to change that. :p However, I am temporarily living in another hemisphere for family reasons until probably mid-December and I don't have the spare time right now to restructure/re-write those sections. I apologize but real life takes precedence. Everything else in the FAQ is correct and current, if you want to read it for answers to common questions.

I am very glad [MENTION=2022267]ShapeShifter499[/MENTION] found the success in doing this, so you guys need to go thank him and even donate money!
