[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Yeah that would be great

Johnfawkes said he'll create a new rctd zip tomorrow.

This was discovered just after release of V2 probably that's why it's not removed by default.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] JohnFawkes:
Yes it can be removed in the twrp zip or via a new rctd remover zip (which I will be creating today when I get off work). This new method was discovered after [MENTION=3138121]seadersn[/MENTION] released the first 2 zips
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Will this new rctd remover zip work on both Pie and also Oreo?

If you don't know yet, that's OK. Just asking.

[MENTION=3250376]ChazzMatt[/MENTION] I tried to flash pie KDZ using Lgup tool, I used Partition DL as the process. However, it gives me a DLL error. I have H930DS and on software version V20F.

What can I do?

I have been testing this new Pie OS in the last couple of days... and I have to say Im pretty disappointed in it.

1) It is pretty slow, not very slow, but not as fast as I thought it would be. But that's not the worst.

2) My main problem with it is the new app switching (Pie) and RAM management. It's bad. The new app switching is pretty much unuseable, if I want to skip back to the prevous app it isnt possible in most of the cases, because it skips apps, the animation is just bad and laggy/buggy compared to other ROMs. It is flawless in LOS or HAVOC, here it's a mess. RAM management is also bad, I constatly run out of RAM and have to reload a prevously opened app. At least I dont have any background crashes (like PowerAMP would stop playing music when I open other apps), but still pretty bad IMO.

I just hoping for an LG Pie OS based CustomROM, that fixes all of these issues ... or else I would most likely have to go back to other ROMs ... shame becasue otherwise I would love LG's skin on Android - strangely- .
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Blueice87:
I had exactly the same experience as you. I liked the new looks and the new features, but the lag and bugginess was too much for me.

I rolled back to Oreo 22j
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xypnise:
I don't know how it happened but i manage to keep old recents style in Pie with nova launcher

Also heres a black theme (with white notifications) that works on Pie

The regular Dev Patched LGUP works fine to upgrade from Oreo to Pie.

In the near future, i will probably change the post #1 to be same as post #2. It's just I knew the Dev Patched LGUP would work to upgrade, while I knew the dual mode version works for downgrading.

So, if it didn't work for him, then he doesn't have drivers installed right, or something....

Sent via open market LG US998 V30/V30+
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xypnise:
I've also noticed that quick charing is now max at 1,5A/9V while on Oreo I had 2,2/9V measured with external USB meter and Accubattery app.

So 13W vs. ~19W

Is that a thing that can be fixed with kernel? Do we have such kernels for H930 Pie?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
I used dual version for both upgrade and downgrade
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Thanks for confirming. All I had really seen confirmed was downgrade, which is why I went with the "safe" choice for upgrade.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] cascabel:
Have you tried ACC? I haven't tried it but it's worth a shot. There may be an option there to increase voltage on charge. Would be interesting to see if it works. It's a magisk module, btw, and has an app as well.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xypnise:
Just tried, and Acc app doesn't support custom voltage change with standard Pie kernel, so there's no that much I can do now.

I have H930DS and I have one silly question. I really want to update to pie , but I want to use dual sim and microSD hack. I saw on Samsung phone having problem with the hack after updating to Pie. That they can't put 2nd sim and sd card in at the same time. Have anyone try this?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Koersten:
I can confirm that. Would be great if this could be solved somehow.

Other than that I am very pleased with the update. Very smooth for me and amazing battery life.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] zohan99:
Can confirm that the TWRP #2 update worked flawlessly, no wipe or format on my end, all the files and data still intact!

Great work guys!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Arcide:
Did you flash it on top of oreo or the #1 pie zip?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] zohan99:
Flashed on Oreo stock, phone was already rooted with unlocked bootloader.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] coronero:
I've actually done it with mine while on Oreo, and I have updated to Pie this monday. Everything still continues to work fine - 2 SIM cards + 1 microSD of 64 GB. It was a hell of a struggle to do it actually, and I've even cracked a Sandisk card while inserting the whole thing. But I've managed finally with a Samsung card (which is slightly thinner and allowed glueing the SIM chip on top, unlike the Sandisk which had the memory chip on the outside).

Would I do it again? Probably not - too much fuss, but as long as it already works - I'm enjoying the ride.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Arcide:
I'm kind of split right now, I have already flashed the #1 twrp zip, but I would like to flash update #2 to get the rct disabled while avoiding another format. As some users mentioned, they have done that succesfully, but it's recommended in the OP to format anyway. Or have I understood that wrong?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] coronero:
And here's proof with screenshots ?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] coronero:
What I find bizarre is the "Software Version" which says V30b-EUR... in the 1st post, but V20b-GLOBAL... on mine. I thought that the 20 stands for Oreo while 30 was for Pie. And other than that it looks and is a pie Stock ROM. Anyone knows how to explain these versioning discrepancies? :rolleyes:
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] hero_p113:
Thanks for showing me that's it's still work unlike on Samsung phone
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] galr:
So far Pie is OK.

I do feel it's slightly slower compared to Oreo, although is looks faster do to the animations.

I do like that I can finally use version 6 of gcams without issues. Finally.

Battery life seems worse, but I have to check with Wakelock Detector and see if a specific app is causing it.

Still worth it only for gcam IMO.

Can someone who flashed via LGUp KDZ do TWRP backup of system?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
We already have a twrp zip for flashing. Read last couple of pages for it.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] cascabel:
Afaik, it's because the zips don't have op partition (unlike the ldz). You didn't kdz to pie before flashing the zip, right? Mine says 20c since that was the last op partition loaded on my phone.

---------- Post added at 12:19 PM ---------- Previous post was at 12:17 PM ----------

May i know your steps? I'm planning to flash 2nd zip but i don't want to format data anymore. Already on Pie via the first zip.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Aptahar:
I need backup, that I can unzip.

Not system.img packed to flash via TWRP

Update: OK, I will unpack system.img))
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] coronero:
That is correct, only TWRP flashing. And the previous Oreo update was also done by TWRP just after the bootloader unlock.

But well, as long as everything works fine (except VoLTE), I see no point in updating through LGUP with KDZ.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
You may not have to flash the 2nd zip necessarily I guess.

Just delete the rct folder in lg persist and see if that works.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You mean for all users there's no VoLTE for the TWRP flashable zip -- or just the India Jio/Airtel hack guide you helpfully put together for H930 Pie KDZ?

[MENTION=3138121]seadersn[/MENTION] didn't always include the op partition on his Oreo TWRP-flashable zips, and the only thing affected was the version number (like now). So he started including it, but I don't remember VoLTE being an issue.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
[MENTION=6815443]JohnFawkes[/MENTION] has developed a zip you can flash which will definitely disable rctd. He has not posted it yet, but will.

Alternatively, you go into TWRP file explorer and delete that folder.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ankurpandeyvns:
OP includes all the configuration required for VoLTE to work. So VoLTE won't work for anyone
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
That's why I don't understand about the no VoLTE thing. Most previous TWRP zips didn't have op image and VoLTE works just fine.

Not that it really matters, but LG-Firmwares.com finally has the H930 30b download links, a full week after we had them.

I've updated post #1 to include the "GBR" region H930 30b KDZ link from LG-Firmwares.com. Even though they are not officially affiliated with LG, they have great sources and usually have KDZ within a couple of days of OTA being available. So, strange they really lagged this time.

Which Version of Gcam that you used. can you recommend one ? BTW M on Pie.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] HalArcane:
Hello guys! I'm really bad at this. Right now I'm running Havoc OS, have TWRP and Magisk installed. (Bootloader unlocked) Version H930

What would be the best course of action to flash and try this version?

Which TWRP zip should I download and what should I do?

I'm downloading the TWRP FLASHABLE VERSION (ROM) (v2)

If I'm correct the steps would be like this:

Go to TWRP, make backup of current ROM.

Then do a "Clean Flash" of the current ROM I'm downloading.

without leaving TWRP, I flash Magisk and LG-rctd-disabler-1.0.zip.

(Do I need to install Gapps?) ------IMPORTANT-------

Then I boot normally.

Is this correct?, I read something about a new upload coming soon that would facilitate the process even more, should I wait for that?

Thanks guys I'm really clueless when it comes to this stuff

V2 does not need the RCTD removal zip if you've already removed the RCTD folder in TWRP file explorer. But otherwise it doesn't hurt and can only help.

It's the encryption disabler V2 does not need...

Disabling/removing root check should not make a phone laggy. It should be the opposite:

All I know is for Oreo it was about last, because the US998 has to work with all North American carriers not just one. Verizon only tests for Verizon, AT&T only tests for their network. Same with T-Mobile, etc.

I have a H930DS India version. I tried to update to pie, I used LgUp to flash pie kdz. I thought I would be able to get VOLTE if I upgraded using KDZ, however, VOLTE never worked. I checked using *#*#4636#*#* and under phone information, VOLTE was not provisioned on the phone and it was greyed out. Software version on Pie said

"V30b-GLOBAL-COM". I thought it should have said EU or IND.

I downgraded to V20F India version using kdz then, VOLTE worked on that, however, Software version strangely said V22J instead of 20F.

I thought if I upgrade to PIE using zip, VOLTE might work so I upgraded using the zip but VOLTE did not work. I checked the software version it again said "V30b-GLOBAL-COM". I think the software version is the problem for me.

I am facing a strange issue now, LgUP is not recognizing my model number, it says unknown model in Model. I wanted to flash V20F kdz again.

Can anyone help? I am using LgUp Dual mode. I have tried the LGUP patched given in the thread too.

* You can get India carrier Jio/Airtel VoLTE flashing the H930 KDZ if you configure it using [MENTION=5579677]ankurpandeyvns[/MENTION] very helpful guide.

The current TWRP flashable zip lacks the OP partition, so you will not get VoLTE right now at all.

Whereas, the H930 KDZ DOES have OP partion and has VoLTE capability -- but for India carrier Jio/Airtel VoLTE, you have to manually configure it:
