[LG V20 ROMs, Kernels, Recoveries, & Other Developm] FNetV1:
I just installed Lineageos 18 on my LG V20 H918 (T-Mobile), here are the issues I have seen so far:

I am being asked to format my Micro SD card before I can use it as portable storage. I have never used this Micro SD card as "adoptable" or "Internal" storage, so I figure that I should have access to the files I have there, there is nothing special done to this SD card, no encryption of any kind, I can even insert the SD card into my Micro SD to USB 3.0 adapter and Windows will see it just fine, a regular exFAT unencrypted volume, so I take it that there must be a bug with this ROM.

The second issue, (this might not be this rom's fault), I was unable to pass the SafetyNet check. Here's what I did.

Initial attempt:

I wipe system, data, cache, Dalvik, but I did not wipe internal storage (Don't think it's necessary to wipe internal storage as it is just storing my personal files, pictures, documents, etc...).

I flashed the Lineageos v18 rom, then I flashed Magisk v21.1 beta (the only version that works with android 11)

I flashed Magisk Manager 8

I flashed BiTGApps for Android 11 – ARM64 taking under considerating the following from their description:

"BiTGApps is a very minimal and optimized GApps package built for Android 11. Designed for better battery optimization, always up to date, no Google setup wizard after reboot, built-in SafetyNet patch etc."

(I placed in bold the portion of interest in that description -- "built-in SafetyNet patch")

I made sure to hide Magisk Manager by giving it a unique name without creating the "pretty looking icon" (as the app calls it on the option given to the user), I can find it just fine under the new given name on the app drawer.

On Magisk Manager, I enabled "MagiskHide"

After this, I taped on "check SafetyNet", I was then prompted that it was going to download the proprietary google code, which it did, after that "attestation failed" (basic integrity = negative, ctsProfile=negative, evalType=BASIC).

Second retry:

I downloaded NikGapps, which also comes with SafetyNet Patch.

I wiped system, data, dalvik, and cache, and then I re-flashed the Lineageos v18 rom again, I reflashed the same version of Magisk again (v21.1 beta), I flashed the NikGapps this time, did everything I did on the first attempt with hiding root on Magisk Manager, hiding magisk manager by giving it a unique name, and then I retried the "check safety net" and I got the same failed result. I was unable to pass SafetyNet with two different gapps packages that promise to patch SafetyNet.

Before I flashed Lineageos v18, I was using stock Nougat 7.0 rooted, had Magisk v18 installed, and always passed safetynet checks, even on three Magisk versions behind. I did a full Nandroid backup before I wiped it and flashed Lineageos v18.

Since some of you are saying that you are able to pass Safetynet checks, what gapps did you install, what root method you installed? Did you have to do anything special in order to get SafetyNet passed?

Another issue I have found, IR blaster doesn't work out of the box, I haven't done anything yet to see if I can make it work on Lineageos v18.

If you read more of this thread you'll see a discussion re the sdcard. It's because Exfat is PROPRIETARY MS and isn't included by default in Android 11, hence los18. It's not officially supported. There's no bug with the rom. It needs third party drivers to support. I have a 200gb sdcard formatted in Vfat which works fine.

Re safety net, don't forget you need to go and set fingerprints as per previous reply. Read the help/man pages from magisk hide. There's heaps of info that'll help.

I don't think from memory you need to install busybox anymore as a seperate item as it's rolled up inside magisk

Los18 7/11

Magisk 21.1

NikGapps basic.

Set fingerprint, magisk hide, etc

Saftynet, gpay and banking all pass
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] FNetV1:
Thanks for the link. After following that guide, I was able to get SafetyNet passed.

Can't believe that's all that it needed.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] TripOG:
You actually have to use the safetynet patch with bitgapps, it doesn't just magically work.

This whole thread is littered with saying you need to use bitgapps or a smaller nikgapps package to get recent apps working, until the most recent nikgapps update the larger packages broke it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] bigsc:
Whoops, I had that backwards. 7.0 is for fingerprints, and the recents issue was caused by Nikgapps. Thanks

PoGo and Netflix are SafetyNet issues (You probably aren't passing and they're seeing magisk as well and at least for me, I need my Play Store to show as device certified for Netflix to show up and operate) and the Bluetooth issue is known and we're trying to work out a solid fix. I have never used Miracast before so I can't speak to that unfortunately.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] coliny59:
Actually I can pass safety net fine and have Netflix hidden from magisk too.

Fixed by clean flashing 16/11 build.

Looking at the changelog a clean flash of the 7/11 build would probably have been fine as well.

Seed Vault

Will there be any chance, we will see Seed Vault in the future? Somebody working on it? When i understand it right, the rom maintainer has to include it?

Still hoping this will get me past my encrypted LOS 16 someday, which is the last working with TWRP Backup and Decrypt.

Why would you think that, lol?

I thinking that because i am still on LOS16, for mentioned reasons.

So its implemented. Its already working on this Phone? Somebody tried it?

I recently ordered an H910, but what arrived is an F800!

Do I presume correctly that this ROM will not work on my phone?

Also if there are any other disadvantages to the F800 Ishould know about I would appreciate the heads up - I know it's a bit off topic so hope u don't mind me asking.

I may well return it for exchange or refund.

Have been following this thread and looking forward to trying this ROM!

I have an F800l. Flashed TWRP for 995, flashed LOS 18 for 995. Everything works.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] justcosmic:
Thanks foryour reply!

Any particular reason youused the 995 variant ?

And can you flash this direct from Nugar and have everything working including finger print sensor or do you have to flash other LOS first ?

Many thanks again
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pavik62:
Personally, I flashed LOS 16, 17.1, 18 in turn. Everything that should work everything works.

The second screen is used as the status bar on Lineage ROMS.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] justcosmic:
OK - so to be sure, flash LOS 16, then 17 and then this ROM (18)

It seems that I have the F800S not the L (don't know if that makes any difference?)

And it's got Oreo installed, so probably have to flash official Nugar first I guess.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] pavik62:
L S - similar.

Install 7.0, unlock the bootloader, flash TWRP for 995, flash Los 16, 17, 18 and gapps for 18.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] justcosmic:
In any case it all looks good.

I presume I will need a physical SD card to do this (sorry it's a couple of years since I've done this!) or am I remembering that wrong...if not the I can get on it right away.

Lastly, are you finding a lot of benefits over official Oreo (which seemed one of the most functional ROMs for the V20 according to what i've read)

Thanks very much again !

That sounds like an issue with the way you unlocked your bootloader. You should be able to avoid it by covering your light sensor which is beside the front facing camera when it boots.

I saw two posts about the bootloader unlock, recovery and root.

#1 https://xdaforums.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278

#2 https://xdaforums.com/v20/how-to/root-h910-v10m-t3664500/post73587358#post73587358

I have H915 hardware. I thought that they are essentially the same idea after seeing that US996 sw works on H915 hw. The H910 is the same as the H915 (or am I wrong). Just make sure you get the patched LGUP and correct KDZ version. Is one process better over the other. I gave up on #1 after seeing that the step3 script had a typo on it (boott.img; probably meant boot1 or boot2 I have no idea). I didn't trust it afterwards. I've done #2 process 2 twice now. Initially following it as posted and a second time today using the US996 KDZ to use as a base instead.

For H915 is there a better platform for roms between H910 or US996 base?

I have skipped flashing the stock roms after getting to TWRP because I never wanted to use them. I just go straight to Lineage after getting TWRP.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
I believe the us996 receives the most support. I found a guide that goes over how to convert the h915 to a us996 so if you want you could try that

At this point, I just want to see if I can fix the static during boot animation.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Since gamma kernel which is really the only kernel that works on more than stock roms doesn't exist for the h915, your best bet is to cover the light/proximity sensors during boot with your finger. If that doesn't work, I'm not too sure what would.

Edit: Actually you could try the version of gamma kernel meant for the h910 since there aren't any hardware differences

I just rebooted and static on boot is gone. All I did before that was flash magisk and opengapps.pico. Do you know if android setup can be disabled?

So I purchased another H910 from eBay so I can test this LineageOS 18.0 ROM without messing with my rooted stock Oreo H910 V20; however, instead of the AT&T logo on the back on my main phone, it says B&O. The box says it's a H910, but the branding is different. Can I do everything on this new phone, that I can do on my AT&T H910? Rooting and flashing files meant for the regular H910, etc?

Use the version of gapps from nikgapps, it doesn't have the setup wizard. When it boots, try flipping it over for the first couple of seconds and see if that does anything. I know that used to be a solution for the static on boot issue

So do I need to LGUP back to UCL US99610p (or just flash USA US99610n or US99610p from the zips in here). After that do I need to do another clean install of this ROM or can I just restore a TWRP backup of the current LOS install after doing this?

Also, I have an ARB0/Pre-10p H918 (on Stock H91810J) that I definitely want to update to this rom after seeing how well its running on this US996. After reading through this thread, it sounds like I absolutely need to go ARB1 before I can install this ROM, correct? Given that phone is still on 10J what would be the recommended path for getting there (H91810U?)?

Is anyone else experiencing severe battery drain when not quick charging?

By this I mean that my battery discharges at a fairly decent rate on its own, but when I plug into a 3.1 amp usb outlet, not only does the phone not charge, but it seems to drain much faster than if I had simply left it off the charger.

I also tried multiple power bricks and USB cables with roughly the same effect.

Don't get me wrong here, if I were to place my charger directly into a wall outlet, it would quickly charge in less than an hour, ....

what's annoying is that when I am in situations where I have no other choice but to slow charge, like someone hands me an extension cord, or the one car charger available is a 1 amp, it is a completely wasted effort!!

Ok, rant over. Now reading through this thread, I see we only have 1 stable kernel, can someone recommend a modification that would allow me to slow charge, should I ever need it?
