Sounds like you did what I recommend over in the clean flash instructions for other variants:

* wipe caches

* flash Magisk first (due to changes with Pie).

* flash encryption disabler

* flash root check disabler

* FORMAT DATA, type yes

* reboot to TWRP from within TWRP

* re-flash Magisk again (encryption disabler dev recommends this 2nd flash right before rebooting out TWRP although he says it's probably not necessary).

* reboot to system

That's what was happening to me as well. I don't think TWRP was flashing it correctly.

How I finally got it to work

Flash TWRP

Format data reboot to recovery

Flash 30D

Flash Magisk

Then both disables

Got everything flashed and running great here. I dirty flashed from rooted stock Oreo. I just wiped cache and dalvik and flashed everything in the order the instructions say to. I also removed any substratum stuff I had installed and disabled all magisk modules before flashing. I removed my screen lock pattern and fingerprints before flashing as well and just set them back up after flashing. No system UI crashes or stuttering here. Everything seems pretty smooth. Thank you [MENTION=9374982]weakNPCdotCom[/MENTION]
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] inuyasha1999:
Forgot to post last night that I successfully dirty flashed from rooted stock 20s with absolutely no issues. Updated TWRP to the recommended version first (had an older version), rebooted, then flashed 30d, Magisk, and the two disablers. I had disabled my PIN prior to flashing thanks to the warning, and just set it up again along with my fingerprints after everything was up and running again. Thank you [MENTION=9374982]weakNPCdotCom[/MENTION], [MENTION=3250376]ChazzMatt[/MENTION], [MENTION=7856962]immns[/MENTION], [MENTION=6815443]JohnFawkes[/MENTION], and [MENTION=6037748]Zackptg5[/MENTION] for all of your work here on XDA!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] d3viou5:
Yes..... I was following that! But I missed the reboot recovery step.

Definitely the reboot recovery worked for me. I flashed 3 times without this step after wiping data and faced the same issue. As soon as I did a recovery reboot..... All good. Are you coming from a custom rom? Seems like stock to stock works fine.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:
Na, I never use a custom ROM. Tho while testing pie, I found that I don't like it and later on I will be going back to 8.0
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] IshsXda:
thank you, had the same FPR issue, this fixed it!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mattgyver:
So far, dirty flashing had been okay.

I made sure to disable all magisk modules prior to updating os, then go through and run the updates of all modules after. Haven't had issues yet!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:
I thought it's a bad idea to dirty flash?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] immns:
Yea usually.. but so far this pie actually better than oreo I thought. Animations more fluid, no crashes, and battery life far better with extra 1hr screen on time. oh yes I did dirty flash it :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mattgyver:
Clean flashing is always the recommended action. That's universal on any ROM on any device. I just know that if there are any issues, I need to do a clean flash first to rule out dirty flashing first.

That and I was lazy and didn't feel like having to fully set up my phone again :p
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] conbak49:
Anyone flashed this from a custom Pie ROM who cares to share steps you took and challenges you encountered?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] weakNPCdotCom:
The fullstock zip will flash over your bootloader, boot, modem and system images. There should be no problems coming from a custom ROM. However, you should probably clean flash if you are running any non-stock image.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Anyone having issues registering fingerprints? Mine goes to black screen when I do. Clean flash and tried with and without magisk installed. Sometime I can get it to display a message that settings isn't responding,. Also appears to actually be reading the fingerprint in the background even though screen is blank.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Try this clean flash workflow:

* wipe caches

* flash Magisk first (due to changes with Pie).

* flash Encryption Disabler (from post #1)

* flash Root Check Disabler (from post #1)

* FORMAT DATA, type yes

* reboot to TWRP from within TWRP (in TWRP reboot menu, choose reboot to Recovery)

* re-flash Magisk again (Encryption Disabler dev recommends this 2nd flash right before rebooting out of TWRP, although he says it's probably not necessary).

* reboot to system

Excellent!
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Did it that way. And also without magisk but no difference. I have a print registered and it works but just had to do it with a black screen while registering and settings still crashed. It's very weird.

Also notice after a reboot the touchpanel is unresponsive for about the first 20 seconds or so.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You need Magisk FIRST for the other two files to have privileges to work. So, doing it without Magisk is going to cause problems.

Going to ask some questions, make some suggestions...

1) You sure you used the files from post #1 as they are the most recent encryption disabler and root checker disabler files for Pie? Older versions of these files in the LAF bootloader unlock thread and Oreo threads are NOT for Pie and will not work correctly. New versions are also attached to this post.

2) My workflow steps above are slightly different from the OP instructions. Just pointing that out to make sure you aren't glossing over the differences. ;)

3) Try using Magisk 19.3 instead of new Magisk 20. After you get everything set up, then you can then update. All my Pie KDZ threads use Magisk 19.3 and no one has any problems. Magisk 19.3 attached to this post.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Actually, I'm quite sure that is not correct. The other two are simply modifying init files to ensure the services that do root checking and encryption do not run. Magisk is not needed as they are not actually executing anything requiring root but rather modifying files simply within TWRP.

Did that. Device was also previously rooted and running your nougat de-bloated version. Just downloaded everything this morning.

I see the differences... while I personally see no reason you have to reboot back into TWRP and such, I followed them to the T just to make sure. I have also re-flashed multiple times in different combinations. Only one I have not tried is solely the ROM (i.e. no magisc, encrypt off, rctd removal). But I might try that.

Yep, did that too :( no go.

-----------------------

I really think this is an issue in the ROM somehow so I am just looking for someone else to verify they can actually register fingerprints after they clean flashed. If someone confirms they can do it.. i'll keep testing. I also have a second issue right now in that google assistant wont speak. Normal text-to-speech works though. Can even get it to do the name speak test in the settings.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
The Encryption Disabler dev says differently, at least for this version we are using:

In other KDZ threads I first posted the July 2019 test version but then replaced that with August 2019 final release, while keeping the instructions the same. He actually has a newer October 2019 test version out with different instructions, but this one is still working fine.

No one in the other Pie thread have any problems when following those instructions. EU H930 has had Pie since July 2019, and then others followed.

* Wipe caches

* Flash Magisk 19.3 first,

* then flash the the two files (Encryption Disabler, Root Check remover),

* REFORMAT DATA (not wipe data, but reformat where you have to type YES),

* reboot from TWRP to TWRP again,

* flash Magisk 19.3 one more time

* finally Reboot to Pie

Anyway, hope you get it worked out.

CLEAN FLASH

https://xdaforums.com/showpost.php?p=80487087&postcount=23
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] d3viou5:
Can confirm I can definately register fingerprints after a clean flash. No blank screens and no system ui crashes. Is your T Mobile boot animation showing up? That was another issue which seemed related to not formatting data correctly. I had no boot animation at all. Before that I had exactly the issues you do, as per [MENTION=3250376]ChazzMatt[/MENTION] quoted. Been running this flawlessly for the last 48 hours. Battery life is way better than lineage.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Gonna go back to zero again later tonight. I'll redo with the extra reboot into recovery. If it's working for others I must have missed something :(
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] immns:
we have to take note any details regarding clean install method. as we thought, many (if not all) were dirty-flashed from oreo 20s currently have better rate of success. Once you've got it worked properly, please consider to share your method or steps (also misstep that should avoided).
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Here is where I am right now and these are the exact steps I took to clean flash (note, this is still having issues with fingerprint reader registration crashing the settings app, and during initial setup google assistant gets a 404 error)

1. Device was already rooted with TWRP installed on LAF and recovery. TWRP 3.2.3-7. I previously had the debloated oreo version 20s installed.

2. Booted into TWRP.

3. WIPED: dalvik, system, data, internal storage, cache.

4. Copied files from post #1 to storage

5. Installed ROM, then magisk 19.3, then dm verity, then RCTD.

6. Performed FORMAT DATA

7. Rebooted to TWRP

8. Install magisk again

9. booted to system.

I am going to try ROM FLASH only this round.

EDIT 1: ROM FLASH ALONE worked, got TMO logo, and no fingerprint crash. I did re-download the ZIP and verified the MD5 this time (did not do that before so maybe it was a corrupt ZIP). Going to clean flash again with everything. Let you know soon.

EDIT 2: Went back with fresh downloads to the steps above and Ii'm back to issues and no TMO boot logo. I am going to double check the other ZIPs to make sure I have the correct ones.

EDIT 3: Verified I have all the correct files. (ones provided as attachment, and the ones in first post were what I already had). Reflashed again this time with Magisk 20.0 but same result. Going to try without RCDT next. One of these extra things is breaking it and I don't think it's magisk.

EDIT 4: At this point, installing ROM only works. Adding ANY of the other zips breaks it. I don't mind encryption and somewhat prefer it. Going to try ROM only again and go through full setup then go back into TWRP/LAF and install magisk and see what happens.

EDIT 5: Flashed only rom and booted with everything working. booted back to twrp but can't get it to decrypt to install magisk and such. so formatted data and copied up magisk. After flash of magisk I'm back to square one again... no tmo book animation, sound messed up, fingerprint registration broke. going to bed :(

LAST EDIT: Well, it's working now. I was trying different combinations and sadly I'm not 100% sure which one finally worked but I think it was this: I had everything flashed and it was booting but without t-mobile logo, sound messed up, etc. I then went back to TWRP and without any wipe of the system just flash the ROM->magisk->nocrypt->rcdt. Wiped data and cache only and that seemed to do it.

I had a feeling somewhere the sound files for the t-mobile boot animation were messed up along with other media files as I noticed there were also no touch sounds. Also, the fingerprint reader plays some animation and that was not working and would give a black screen. Even when booted all the way up, stock ringtones were missing. So, figured re-flash the ROM over it and see what would happen and that seems to be it.

Maybe one thing I was doing that other were not.. I was always wiping SYSTEM.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] d3viou5:
Damn, that sucks. Are you flashing from twrp on laf or twrp on recovery? Clutching at straws now but maybe it makes a difference.......
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:
If I may,

Format data reboot to recovery.

Full wipe. Data, system, ECT

Flash 30D

Flash RTCD remover

Flash no verity

Flash Magisk.

Reboot to system.

That's how I got it to work.

Edit, I had the same issues everyone else including you had. I was also on stock 8.0

When I kept formatting data and rebooting back to recovery, I would clean wipe, flash 30D, then Magisk or the method chazz had said which is flash Magisk then 30D.

Nothing was working till I tried the steps I listed above.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] kpoloboy:
Just want to say this did it for me.

had all the issues you described so i flashed right on top of 30d again and followed exactly to the T on your last edit. thanks man!

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] IshsXda:
hmm not my experience. Almost the same (lclean flash, even formatted SD/internal lol) Recents menu seems to delay for a milli sec actually relative to oreo. Oreo was blazing fast. LG's setting menu is still very sluggish. Overall its such an underwhelming upgrade lol i mean not just the V30 but Pie in general especially its navigation is so stupid. Android 10 basically ports iphone gesture/animations which is great but like is that the milestone to expect now? Expect more iOS features to be ported as google features in 11? Anticipated news of recent is google's version of air drop being tested lmaoo. Meanwhile iOS is getting closer to android. Apparently they have drastically improved accessibility to local file management with a new file app similar to android.

Anyway, have you happened to get dual speakers running? Seems oreo mixer mod (whiskeymod) does not work T.T (breaks audio had to restore)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] wtang:
I just want to say thanks to [MENTION=9374982]weakNPCdotCom[/MENTION] for creating this flashable zip for Pie! I had the same problems as [MENTION=3089452]thebitjockey[/MENTION], meaning no T-Mobile logo screen during boot, no sounds, etc. I followed his recommendation to boot into TWRP again and reflash the 30d ROM, reflash Magisk/DM Verity/RCTD, and wipe only data and cache. That did the trick and everything is working now.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] immns:
Sorry im not using dual speaker mod, just enable dts and equalizer. that mod is outdated, other mod deleted. You can ask them to teach you something, if youre willing to learn further.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] thebitjockey:
Now a couple days in and this is running butter smooth and much better than oreo did for me. Here are some additional things I have done at this point.

1. De-bloated some (I'm still working on this here and there and once I have my list I'll post here).

2. I use google dialer so I have the framework module installed via exposed so I can install that from play store.

3. I registered and purchased the beta version of G-THEME 3. Works great and I love the fully dark look.

4. Using Lawnchair Launcher with Lawnfeed.

Now I have to decide if I get the crack in my screen fixed or just buy a pixel 4 :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] IshsXda:
" that mod is outdated, "

No It works across all AOSP pie.

"You can ask them to teach you something"

Uh preeeetty sure if there was a dev or member that can teach me something regarding dual speaker mod on stock pie then there would already exist a a post regarding how to dual speaker on stock pie lol.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] immns:
perhaps aosp pie using oreo blobs come from LG source long time ago (pie source has not released yet that time). If you insist to get dual speaker mod, then flash back to oreo or aosp pie will do the job for you, let alone you've mention that you don't pleased with stock pie experience. :fingers-crossed:
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] IshsXda:
I simply asked if you knew of a dual speaker mod. That is all. I dont really care too much about it. I just wanted to know if you knew lol. End of conversation. You dramatize a bit too much.

I think many would agree that Pie was a very minor upgrade. And LG, have also have not introduced anything that couldnt have been done with a security update.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:

I flashed new TWRP rebooted recovery

then I did all the files from first page

cleared cashes

reflashed TWRP just to make sure I didnt loose it because I dont have it in LAF

reboot and All working fine even TWRP still there.

Little confused in reading your post...

We don't have any "new" TWRP. Maybe you mean the new TWRP-flashable zip (firmware, ROM) from this thead? :confused:

The TWRP version you should be using is stable

TWRP-3.2.3-7

, which we've had since early December 2018. Stable TWRP-3.2.3-7 is what is posted in the op (post #1) of this thread as well as the T-mobile KDZ thread I maintain. Our TWRP dev recommends we use stable TWRP-3.2.3-7 still, even on Pie firmware and any AOSP/Lineage ROMs.

I'm only commenting because a few months ago our TWRP dev did release an experimental, beta "Pie" TWRP version -- then almost immediately said for everyone NOT to use it. He said to please continue to use stable

TWRP-3.2.3-7

.

Maybe before updating to this TWRP-flashable zip (ROM) you were using some even older version of TWRP? So it's new to you?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] SIMONAK:
I had older version so I did update the TWRP to the version posted on first page.

I was running old stock oreo so there was no need to update TWRP before.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Vuzeultra:
Incredible work guys, I've been following it almost everyday ?

But I'm confused on what would the proper steps be for upgrading my phone already running Lineage Pie to Lineage 10, I know these files are needed for that. Should I flash this stock pie Modem and Bootloader only? Or something do something else? Any clarification would be amazing. I'd rather get the right info before screwing around on my own.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:
I could be completely wrong, but I think LOS is using Oreo blobs still, so you should be fine.

You need to ask this in the LOS thread since users here don't run custom ROM's. Or generally tend not too.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You also need to ask go into that thread and ask what doesn't work yet in Lineage 10. It's being improved day by day. But I see discussions where for some it's not yet ready to be daily driver.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] xionbunny:
None of the Android 10 roms boot on this device.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Eliejo:
I was having system UI issue whatever I did. The only way I get to solve it is dirty flash through 20s and fix the lockscreen issue as per mentioned on 1st post
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] weakNPCdotCom:
If you were dirty flashing this package, there is a change that lockscreen issues will occur. I ran into problems with fingerprints myself where it wouldnt register them. That was because there were some existing lock-screen files that were not working with Pie correctly. I had posted a little note in the OP regarding this.

Ultimately, you can follow [MENTION=3250376]ChazzMatt[/MENTION] instructions for a clean flash above, or you can try going into file manager in TWRP and deleting the lock/pattern/security files and related .db files in /data/system.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mattgyver:
Alternatively, what I did was just turn off security first before rebooting to TWRP to dirty flash. Set lockscreen to swipe. That way, after update, I could just go register my fingerprints again. Just another way :D
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] squarebale:
Lost TWRP on Recovery

OK ,so something strange happened:

I followed all the instructions, dirty flashed over 20s and successfully booted into pie. Played around for a bit, then decided to boot into TWRP on recovery. Note that I had TWRP on recovery and LAF. From Magisk, reboot recovery. Got the expected 'reset your phone' message. Selected 'yes' as worked so many times before to get into TWRP on recovery. Instead got a very brief message to the effect 'resetting phone' followed by reboot. It actually hard reset my phone! Took no more than 2 or three seconds. On reboot got the 'setup you phone'

Somehow TWRP on recovery must have been replaced by stock recovery.. Luckily managed to boot into TWRP on LAF and restored 20s from backup,, followed by dirty pie. Boots OK into PIE, no issues. Note that now when I try to boot recovery I get the dead droid and 'no command'

Question: Is there a way to flash TWRP back onto recovery from within TWRP on LAF? Or anyway at all?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] immns:
You can flash it using img flasher on TWRP, there's a button to switch img flashing or zip flashing. Usualy twrp distributed as img file you have to switch to img flasher (default is zip flasher), then select recovery and flash it. You can also flash using root with dd command within android terminal which I dont recommend since it prones to fatal human error
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] squarebale:
Thanks so much, that did it! :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] BROKEN1981:
Wow, that's really odd. Wonder how that could have happened. Good thing you took the devs advise and put TWRP on LAF. That's basically our get out of jail free card.

T-Mobile didn't think we needed fastboot commands even though they let us unlock the bootloader.
