[LG V20 ROMs, Kernels, Recoveries, & Other Developm] VelosterM14:
Hi, thanks for the reply. Sorry if I wasn't clear enough with where I am trying to go.

I am trying to get back to a rooted stock, Nougat (10P, I can get to 10U from there). The bolded items are details I already provided in my post above. I might maybe have a go at Oreo someday if I can just get back to Nougat, but I'd be happy to just get back to a rooted stock Nougat.

I figured I would at least need to:

flash stock 10P kdz

redo the 10P lafsploit

install magisk of choice

but ran into issues.

1) If I asked somewhere else I am almost certain they would tell me to go ask here, because LOS 17.1 is where I was, and it is not stock. The LOS people would be most familiar with whatever/anything funky LOS 17.1 might do to a stock setup that I need to know if I want to go back to stock. That was my line of thinking.

With the need nearly anyone running Lineage OS with a H918 V20 would have of going back to stock if they want VoLTE support on their phone, I figured I was probably not the only one trying to do so. Why? So we have something to use when TMO turns off 3G, H+, etc. (anytime now) and until I can find us a couple phones we can stand to use for our next phones.

I have seen multiple mentions in other topics/areas that Lineage OS changes the standard partitions or sizes of them which can cause some problems with people getting back to stock. such as kdzwriter thread. But not enough details to understand if it applies to me. Yeah, I asked over there too. Crickets.

I had problems with my H918, just trying to flash stock TMO H91810p KDZ back to it with LGUP. First hurdle was needing right DLL for LGUP to recognize but I got past that. It finished and seemed fine, reboots, but will never get past the Tmobile screen. Have let it sit > 1 hour, doesn't matter. Phone gets quite warm but I suspect it is in a boot loop. No idea why though. have tried re-flashing too, partition DL mode too, all "work" but after reboot its still always getting stuck in T Mobille screen.

versus our "spare" H918 that we left stock but was rooted etc. I flashed the same H91810P bone stock KDZ file to that phone and its fine. can lafsploit etc. and since "my" H918 is now fubar I am up and running with "the spare".

So I figured if there was anywhere people would know of the "right" way to get back to stock from 17.1 -- and anything extra I should plan on needing to do -- this would be the place to ask.

Thanks for any advice. I'm pretty technical but I am not constantly flashing and reflashing roms, rooting, etc. Only when I have to for some reason although I did keep 17.1 updated as the updates came out, just that (EDIT!) somewhere around March of '21 I think it was, the update notifications I was getting from the update checker were for 18.1 which required a manual upgrade.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
To go back to stock, flash the kdz and then factory reset. You did the right steps however, unless your using partition DL, lg up does not erase any data which is why you're not able to get past the t-mobile screen.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] VelosterM14:
@xxseva44 thank you sir. That got it and I am back in business on this phone that went fubar on me. Very glad to have a spare again!

I am pretty sure I had tried factory reset after flashing at least once, but apparently not in combination with correct flash type.

And the funny thing is, that erasing screen is one thing I was seeing just about every time, after flashing and rebooting, every time it would hang and I'd have to pull battery, when I would power back up there was a period where the black screen would come up and the funny halo animated circle with "erasing" in it would come up.

But, when I powered it up this time with hold vol down and power down, let power button up for about 1sec after LG logo pops, then back in til the data reset white screen comes up and I said yes, when it rebooted, it did the right thing.

Took little longer on LG logo, then saw Erasing halo, then booted and went to Tmobile screen, and after maybe 30 secs I was greeted with fresh android data/formatting screen and a welcome.

Thanks again, this was extremely helpful!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
No worries👌👌 Glad you got it sorted out
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] VelosterM14:
PS: Thanks everyone who worked on 17.1 and into the future with newer releases. The ONLY reason I left LineageOS is because (thanks to Tmobile using proprietary means) we could not use VoLTE on our H918's and they will be turning off the older stuff anytime now. We had to get back on something that could use VoLTE until we can find phones we want to buy. (or turn blue first hehe)

If anybody ever figures out how to get VoLTE working on H918 with LOS 18 or newer, we will be back (assuming it will be possible to run with no google someday). LineageOS has been great for us.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Volte is not coming to custom roms. Lg uses a proprietary implementation and adapting and porting their ims framework is practically impossible without having the source for it. Samsung does a similar thing as well.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] VelosterM14:
Understood. Just pipe-dreaming out loud I guess. :)

Hey if you don't mind, I have one more question. I wasn't expecting to need to ask any more questions but just ran into something weird.

I was able to get re-rooted with lafsploit, update to 3.2.3-4 TWRP, wipe (format) data - the one you have to type "yes" to accept so the encryption etc could be reset by android on boot up etc. Almost everything has been great trying to get the phone set back up for my wife, until...

Only thing is, something is not right with trying to install a user certificate (CA cert for our setup around here) and would be installing WiFI next. I have tried this setting a pin code, both with and without setting up fingerprints (it requires you to specify a more secure lock screen as part of this) -- but after browsing to CA cert, giving it a name and setting type to VPN and Apps, I get stuck in loop of being prompted for my pin, over and over again.

The pin works to unlock the screen etc, even after reboot, but something is not right, maybe with credentials storage. I can't save/add this or our WiFI cert to user certificates store. Has worked fine with the other phone doing things the same way.

I've tried wiping data again, going back to the first backup I made of progress on the phone after succesful root (I had installed dimm0k's 10U keep root .zip after that), wiping cache and dalvik etc. but it just won't store a cert on this one.

Does this sound like anything familiar to you? This is the phone that was running LOS 17.1 for long time. It makes me wonder where user certs get stored on the phone.

Thanks!

EDIT/PS: I even tried deleting the whole screen lock pin setup and trying again to store cert, so it would force me to set one, thinking maybe if it set the pin as part of sequence it would store the cert. It sets the pin correctly but still will not save/add the cert to the certificate store. Just keeps asking for pin over and over again.

EDIT AGAIN:

Can't find anything anywhere on net about it, specific to V20 or otherwise. Closest thing I found was talking about old Marshmallow or KitKat something but that was where I got idea to delete existing PIN screen lock setup already set and let it create one as part of the import cert process, evidently that fixed it for somebody. But not for me.

Did you flash 15.1 on top of 17.0? I didn't even think that was possible or would even boot up....

I might decide to break up the folders to more clearly indicate 15.1, 16.0 or 17.0
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Migush:
I did. Surprisingly only the google services didn't work as they should. The sound issue from Los17 was still present.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Black6spdZ:
Its about time Google put a native dark theme back in android!! KK was my fav version. I dirty flashed over latest Dec 16.1 and also have the BT audio problem where device will be connected but audio just plays over the phone speaker. Only other small gripe is not quite liking the new gesture interface and having to change back to 3-button mode. I'm sure the small kinks will be worked out in short order though.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Cyber-Shadow:
I've managed to dirty flash LOS 17 over 16 on my h990, it boots successfully as long as magisk is not installed. Using the latest v20.1 the phones enters fastboot after the LG logo, and with 19.3 there is kernal panic. If any information is required regarding the issue im happy to provide it. Thanks x86!

Edit: Reinstalled magisk v20.1, unsure why it was booting to fastboot before but it seems to work. I will report back with anything else interesting.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sajadzare:
yes that is true, i see lineage 17 review in youtube before rebuild for v20 and the navigation gesture had so soft animations.

i think this lag is related to v20 cpu process and maybe will be fix by kernel developers.

Now we waiting for fixing important problems in los17 like Call isuue (just worked in speaker mode) and Easy Root method

Does gamma v13 work with this ROM? Have you tried omar's thermal mod@gamma kernel's thread?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Migush:
I'm running the latest build without Gamma, but with the LSpeed Magisk module and the smoothness/speed it is absolutely stunning. Seriously, for me the difference is insane.

Edit:

This turned out to be incorrect. Using L speed lead to quite a lot of freezes.

I've encountered an issue with the los 17 on h990ds, weirdly there is no headphone out! It seems to only play through the speakers, anyone else encountered this?

I'm dying for the next vs995 update, because while it worked, it was simply the most stunning difference I've seen in a version upgrade from a UI standpoint. I was just starting to get all the gestures down and it was amazing.

After dirty flashing from LOS 16 to LOS 17, it worked fine-ish, heat was at insane levels at first because maybe of the phone setting up

But I guess some others like /u/cnjax and /u/MEMO#22 perceived this to be slightly demanding, maybe it's best to clarify the intent there.

I'll be going back to 16, but here's a list of issues I've had when dirty flashing over LOS16:

Phone can establish a Bluetooth connection to my car and claims audio is playing through the speakers... but it's coming from the phone. I do see which artist etc. is playing, I can control playback from the car, but sound is coming from the phone.

Google Maps doesn't work. Flat out. It is forever searching for a route.

Programs that need GPS (and have the permission to use it) may not get location data... sometimes, after 10-20 minutes, they do. Sometimes never.

Programs do not get permission to write to storage, and I'm not always asked to give permission. So they don't get it.

Performance is worse than before.

Plus probably many more issues.

I suppose with a factory reset etc. it might be more usable, but that's nothing I want to do if I can avoid it. I might be switching phones soon anyway (for a while).

report on vs995 + magisk 20.1 + gamma kernel 14

clean flash from nougat stock rom

performance is great.. yeah ✌

battery life seems to improve(idk it might be the kernel)

IR works,fingerprint works and bullshits

issues

call only work in speaker mode(sometimes phone reboot while picking calls)

quick setting flash light is broken(i guess this is caused by gamma kernel. i experience same on los 16)

inbulid browser cause kernel crash. yes kernel crash while using browser sometimes. i have no idea but it could be gammas prob again.

unfortunately i didnt pull logs

but hey, its a nice rom and it feels gooooood.

What's not working according to my test :

I understand the dev currently need catlog but I can not provide him unfortunately and I just inform my test and hope he find enough time to fix them.

Currently I'm running latest update which is 12/27 on h990ds ... I dirty flashed it over lineage 16. Have magisk installed which works perfectly.

1- Can not charge the phone when the phone is off : It makes the phone switch to fastboot mode.

2- Can not use normal earpiece and speaker only works ... I tried both when calling and whatsapp ... It looks like the phone only detects speaker.

3- There's some problem with 4g (LTE) for me, If I set the option of sim card to LTE the signal will go away and I can not call nor anyone can call me text message ... But 3g works fine ... It happened in 16 in early updates for me but after some updates it got fixed ....

4- Quality of sound when I recorded and heard my own voice wasn't good enough ...

5- Battery indicator in status bar doesn't show percentage even though I set the setting.

May I suggest before you get into trying custom Roms and kernels that you explore XDA a little further perhaps start here:

You will find this place is a forum with a search function, and even if you can't quite figure out how to search XDA, you can Google xda

https://www.google.com/search?q=gamma+kernel+v20+site:xdaforums.com

If Google is to difficult here's another secret: those words at the top of the page that are underlined are links , and if you click the one "LG V20 ROMs, Kernels, Recoveries, & Other Development" it will actually take you to this amazing whole other place (https://xdaforums.com/v20/development)

where you can directly click on the Gamma Kernel V20 thread link which already has all of the information you are asking for and hopefully there your posts won't be replied to with such high levels of sarcasm.
