[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Most developers have moved on to LOS-17 (Android 10) ROMs. I'm glad you asked for "well-maintained" vs "best". ;) People who come to V30 Telegram thread asking for "best" ROM often get warned. The different ROM devs/maintainers aren't competing with each other -- different users have different needs (stripped down for performance vs throw-in-the-kitchen sink options or maybe attempt at some in-between middle ground). What's "best ROM" for one person is not what another person wants at all.

Pixel Experience

* and Pixel Experience Plus (more options than very sparse Pixel Experience; why do you think actual Pixel owners often install custom ROMs?)

are the most popular according to discussions I have seen.

There's a new LOS-17 based ROM on the horizon, called

Zen X

. Havoc team recently split over the direction of that ROM and this is the effort of other new team.

A couple of the ones listed above are not on XDA. Some of the ones listed above look neglected but if you click on download links you see they are actually current. For some reason Devs here on XDA post threads, then seemingly walk away. :confused: They chat amongst themselves elsewhere (V30 Telegram) and can be reached there. They often do read posts here, but don't have a daily presence.

For any LOS-17 (Android 10) based ROMs you need to be on stock Android 9/Pie stock firmware first as LOS-17 ROMs require stock Android 9/Pie blobs (drivers).

One dev [MENTION=2022267]ShapeShifter499[/MENTION] is keeping

LOS-16 (Pie/Android 9)

updated for all V30 variants (including T-mobile H932). New build

almost every day

! (Go to that page, scroll down. You will see both the "H930" -- bad tree name, it's actually universal , for all V30 except T-mobile H932 -- and the "T-mobile H932" specific builds.) You need to be on last stock Oreo/Android 8 firmware for that, as LOS-16 (Android 9) need stock Oreo blobs (drivers).

Here's the list of

current bugs for LOS-17 and LOS-16 ROMs

. That list is kept up to date by [MENTION=5906767]tech_infinity[/MENTION]. LOS-17 bugs are being solved, but last time I checked LOS-16 still had less bugs. All LOS-17 and LOS-16 based ROMs will have the parent ROM bugs. For instance, no V30 LOS-based ROMs have carrier VoLTE or VoWi-Fi calling -- and never will. So, don't go jumping from ROM to ROM and complain in every thread about the same bug. ;) Until a parent bug is fixed in the V30 LOS tree by the LOS dev, none of the LOS-based ROMs will have a fix. Yes, there may be ROM-specific bugs also. So, look at that linked list and you will know whether it's something that may not be in a different ROM you try.

All the V30 LOS-based ROMs above utilize the Quad DAC. Not sure about MQA, someone else can answer that.

As for GCam, I know LOS ROMs come with a camera -- obviously not LG stock camera -- but whether it's GCam or Open Cam or some other camera depends on the ROM group or even the V30 maintainer. You can always install the GCam of your choice. There are many and often a debate over which GCam is better.

V30 does NOT have a stock vendor partition. V30 doesn't have Treble, as it launched with Nougat. Only phone series that launched with Oreo or later have Treble vendor partitions. The ROMs I mention above are simply installed via TWRP and have nothing whatsoever to do with vendor partition.

Yes, you can CREATE a "vendor" partition from unused space and there are a few minor ROMs here and there which are installed via self-created vendor partition, but I urge you not to do that.

Be sure to read the V30 Custom ROMS FAQ:

Having said all that, on all previous Android devices I owned since 2010 (phones and tablets) I always ran custom ROMs. On this phone I am running stock rooted Oreo with Magisk and Xposed mods.
