Need to? Maybe not. But, you should anyway. I've had flashes erase internal data for no reason. I also pull my Micro SD card before flashing, just to be safe. Always a good idea to backup EVERYTHING before a flash or wipe.

Fixed bootloop

Thank you so much for this zip file.

My phone had been stuck in a bootloop and I thought that it was bricked forever because I couldn't even get into TWRP ( I even went so far as to replace my phone). Then I found this zip and although I figured that it was a long shot I decided to extract the system.img and boot.img from the zip and then flash them to my phones bootloader using fastboot. It worked and now I have both my new LG V30+ and my old LG V30 that I replaced with it as a spare. :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] spacepirates:
TL;DR: On the Verizon network, and an unlocked US998 phone running this firmware, my phone wouldn't receive calls (but could make calls and SMS/MMS/4g worked fine)

FYI, I have an unlocked US998 that I use on Verizon's network. When I flashed this zip, my phone would send callers to voicemail (my phone would never ring and I wouldn't even get a missed call notification - just a notification I had a voicemail). Took me a while to actually learn that I wasn't getting notification and not just that I missed it.

I flashed the Verizon specific firmware and everything works (also got my first experience with wifi/hd calling). Kind of disappointing though, since the VS996 firmware removes smart/context settings (set volume/wifi/bluetooth based on location), which I used (and liked). Also carrier bloatware (which I'm slowly fixing with TiBu).

I guess my point is: it is a good idea to confirm base functionality of your phone after you flash firmware. I checked out-going calls and texts (used to run AOSP which had a bug w/Verizon that you had to send a text first before any incoming calls/texts would work) but failed to check incoming calls.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mac62:
The context awareness is still in the Verizon rom, the menu access has just been removed. Install something like Shortcut Master and search for "RecipeListActivity". Works great for me.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Interesting. You were able to get Shortcut Master to work? Others reported on stock Pie, it no longer worked for them.

Not this one specifically, but I think T-Mobile H932 stock Pie. [MENTION=5631635]BROKEN1981[/MENTION], was that you who couldn't get it to work?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mac62:
Changed my initial response to reference the Verizon rom; but yes, works great. Have headphones launching my podcast app thanks to Shortcut Master. Currently on VS99630c, TWRP flashed.

Correct, can't get root rights granted.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Spiricore:
Just dropping by to share my results. Clean flashed (following OP instructions) this on my US998 running stock Nougat on Mint (T-Mo) about 36 hours ago and things are going pretty well. Wanted to say thank you for putting this together and supporting it!

Seems like a solid daily driver with the only issues I've experienced being the same as others have reported:

Boot times are definitely longer than stock Nougat.

I did experience a freeze at the LG logo early on, but was able to use Vol- and Power to reset and it booted up fine.

I see Wi-Fi Calling in settings but can't click on it.

Happy with everything else. Thanks!

What's odd is that I realized today, after I thought wifi calling was broken on this ROM, that it seems to be working okay now. I don't know what happened. I didn't upgrade the ROM or anything, it's just working now.

It seems to be something to do with the UI for wifi calling in settings, but I managed to get it turned on through Shortcut Master...

Search shortcut Master for WifiCallingSettings. There should be two menus. Not sure which one actually works, but go into both and turn them both on.

Now my phone does everything it used to on Oreo, AND I get better battery life in general

hi, we dont need vendor partition to flash this rom...? im on H931 converted on US99820a (Oreo 8.0.0) with bootloader unlocked and twrp 3.2.3.7
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Please never install vendor partition. Never.

Stop with the vendor partition questions. :)

No regular stock-based or LOS-based ROM is ever going to ask you to do that. If a ROM says to install a vendor partition, walk away from it. It means all your hardware like Quad DAC, fingerprint sensor or even speakers will not work. If you ignore this advice, you've been warned.

Also, read the warnings about

Pie from the Root Sticky thread

I gave you. Do NOT update to Pie until you are aware of the warnings! Once you install stock Pie your phone is permanently changed. If you then downgrade back to Oreo to run stable LOS-16 ROMs, you have to always run in Permissive mode for camera and flashlight to work. So, better to not even update to stock Pie if you plan to run LOS-16 ROMs. Just update to last Oreo.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] estemanito:
OK i followed all the guides, i tried to install LOS16 but having a bootlogo loop i restored 20H then flashed this rom with Magisk but the phone dont boot too, i get the LG V30 ThinQ logo then nothing else happends... i dont understand why, i followed all the steps correctly...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Rafeh:
I converted H933 TO US998 running 20h but unable to install pie stuck on boot logo, downgraded to nougat then again to pie not working tried everything. Maybe we need to wait for stable build or other rom.

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Up

Someone else will have to give their opinion on that.

Although I always ran custom ROMs on ALL my previous phones and tablets for the past 10 years, I only run rooted stock firmware on the V30. I use various Magisk and Xposed mods to make the changes I want, like the Anxious V30 mod and Gravity Box. (edXposed can pass Safety Net.) I have features of G7/V40 stock LG camera, dual speaker, forced HIM, automatic call recording and other stuff.

Stock Oreo firmware is already very optimized, especially the 2019 releases. US998 Oreo has little to no bloatware, and anything you don't like can be frozen with Titanium Backup. Any features you do want can be added with mods, while keeping LG stock camera.

While I updated my spare US998 V30+ to Pie, I don't use that phone. (I'm about to give that phone to a brother-in-law in Brazil.)

My daily V30+ phone is still on rooted stock Oreo -- but with Magisk and Xposed mods. I don't see anything about current early Pie that I need, while I do see some problems with Pie I do not want. ;)

Maybe in the future LG will add features to stock Pie which will make me change my mind.

PS my problem with microphone is semi-solved. It seems like my secondary microphone got damaged in around the same time when I got updated. And for calls on speaker it uses this 2nd mic, instead of main one, which seems to work just fine.

Post one shows a security patch of September 1, 2019. I thought that I was on the latest, but apparently not? Are they the same.

Do I need to install September 1 zip. Is so can I just dirty flash it?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
There's only been one USS98 KDZ so far, and it had August 2019 security patch. Whereas others like Verizon, Canada, and T-Mobile had September security patch even though they were all released about the same time.

The TWRP flashable zip in this thread is taken directly from the US998 30b KDZ. It doesn't have a different security patch. This dev and another (working as a team) create almost all our TWRP flashable zips. Possibly something he wrote for another thread just didn't get changed. I do that sometimes. ;). I maintain 6 KDZ threads.

I tried going from Oreo 20h (US998, already unlocked and rooted) directly to Pie with this zip...stuck at boot logo forever. Tried going back to Nougat through KDZ, that worked. Master reset, flashed twrp again, tried again, still stuck on logo. If it matters, while I was on Oreo, I also wiped everything and then tried flashing a custom rom (also pie), Havoc OS, same thing happened, stuck on boot logo. This was originally an AT&T H931 which I converted to US998...

I'm thinking LG just isn't going to release a good Pie KDZ. My battery doesn't stay charged as long. I might upgrade and have to give up root, but I'm getting another LG. Tough phones. Almost impossible to brick. I've flashed mine to Hell, and always brought it back. The V30 variant is tough. I'll take it over Samscum any day.

I can't afford an unlocked phone, so I'll have to get it from AT&T, which means locked bootloader.

I can use my insurance and get a V35 cheap, brand new.

[MENTION=3250376]ChazzMatt[/MENTION] once installed; from oreo to pie via twrp zip, is there any downside to not having installed Pie from the KDZ? I'm asking because I've had no problem going to LOS 17.1 but when trying to install Havoc 3.2, the flash in TWRP throws errors. Could be a bad download or just problems with that rom. Those are the only two Q roms I've tried so before I go further I'd like to get clarification. If I need to re-due stock PIE via KDZ, I'd like to do it sooner rather than later.

So, I'm assuming that stock US Pie is just dead. It's been a year.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Not quite a year. EU H930 got Pie last July, but yeah. I think the holdup was Sprint LS998. They rejected LG's Pie because VoLTE didn't work right, and the Open Market US998 has to work with all carriers, including Sprint. That's why the US998 Oreo was released LAST, after all the carriers got their versions and would have worked the same with Open Market US998.

Sprint was waiting for a revised Pie build.

But between Sprint rejecting LS998 Pie, the T-mobile/Sprint merger, LG not doing well financially, I think LG just moved on. Now that T-mobile owns Sprint, they want people to buy T-mobile phones. So,

I'm not sure T-Mobile will pressure LG to deliver Pie for a 2017 Sprint phone...

Hi Chazz & co.

I really appreciate the work put into Havoc ROMs.

I recently stopped being able to receive calls to my US998.

I foolishly updated to 30b zip thinking it was 20b and I think that's where my issues started.

Went from 30b > 3.3 > 20h

When I flash 20h zip, i can get all functionality back but hate stock.

If I flash 2.9 or any other Havoc ROM, I can make calls (data eventually worked too) and send SMS but I don't receive calls. The phone doesn't ring but goes straight to VM.

When making calls, it takes a cool 5-8 secs before the line starts ringing.
