New h990ds online. Not sure anything on this, the dmesg are hard to catch, as once you pull the battery you lose it. However I'm not even sure you'd get anything as going into fastboot means the kernel did not even boot properly. But I'm trying again...

Added new h990 (single), using just new method. Please try and test...

If this fails to boot again, I'll try another method....
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
I'll see what I can do in the next ones. I cannot promise it'll make it into Official, but can test with unofficial. Right now, this is the test one I'm using: https://github.com/x86cpu/android_kernel_lge_msm8996/tree/lineage-15.1-updates

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] jl10101:
Thanks, but this latest build for single SIM H990 still ends up in fastboot. Do the fastboot details matter at all (on screen)?

[MENTION=2881807]x86cpu[/MENTION] still fastboot after LG screen. Do you know roughly what might be causing the kernel to not start?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] x86cpu:
Not really, it's the default fastboot/download mode for LG.

I do not know, all the dirty santa fixups are in this kernel, so in theory it should boot, but I do not have a h990 to try with, as if I did I could just make the kernel over and over and not have to give you such terrible non-working builds.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
It's all good man. I'm happy to test whenever and whatever. Even if it's by PM until we get a working build to add to the thread, or here. Whatever works for you. Don't feel bad, you're already doing miles of work for the other variants, and it takes 5 minutes to flash a new build from you, find out if it works and restore a backup if not. Just keep plugging away with anything you think might work. If you'd like, I can link you to the Nandroid backup I did a few days ago, you might be able to dig around and find anything you might need. Otherwise, I'm happy to help with anything needed. It'll be well worth the tries. Hell, if I knew how to I'd build and test the kernels myself to try. Sadly I don't, so testing is the least I can do for you for trying.

Ok weird thing just happened I rebooted my phone (h918) and lost fingerprint settings completely
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Type2501:
Jump from 0427 built to 0516 built. Video taking problem is now gone.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
So, not sure if it means anything but I was playing around with fastboot commands while my phone was stuck in it, just out of curiosity. I ran "fastboot continue" to force the device to continue to boot, and it was scrolling a bunch of random stuff I couldn't read fast enough, I got a flash of the "your device can't be trusted" screen in what looked like an ASCII translation (lol) and then after a couple more seconds of scrolling, the screen went black. When it came on, it had this on the screen: https://i.imgur.com/QQME3Us.jpg

Unsure if any of that means anything. I'm failing to get a dmesg while on the fastboot screen, so there isn't much else I can do sadly. I was also playing around with unpacking the ROM zip and opening the system.new.dat.br file with various tools from other XDA devs, converting it to a standard .new.dat file, etc. but they all kept getting memory read failures when trying to extract it, not sure if that means it's corrupt in some way? Looking around, the "crash on the lk" message seems to be related to the Nexus 5x, possibly referencing the stock kernel, a bad boot image/kernel image, or something else.

NFC is greyed out in settings and it ate the most battery infact wakelock'd my H910. I uninstalled NFC Service via Titanium Backup but now its Kernel which is eating the most out of battery. Is it normal? I am barely using my phone with screen on for less than an hour and the phone doesn't last for total of 8 hrs.

With the latest 20180518-H918-10P build, doing a clean install during setup the Pixel Setup repeatedly crashed. Couldn’t get passed that point.

I had been running the May update(0512) with the latest security patch but I had dirty flashed that.

Update: Just tried a clean install of 20180512. That also was crashing at the Pixel Setup.

I restored a backup of 0427 then dirty flashed 0518 and that works.

Quick thing, running on my h910 and it seems to work pretty well except the nav bar disappears. It's seemingly every other time I unlock doesn't matter if I use the finger print or tap to wake. After awaking and connected to smart lock (meaning being kept unlocked) the nav bar is nowhere to be found the only fix is to turn the screen off an on again that I've found. Unsure if this is an 'only me' thing don't want to re-flash if it can be helped but let me know!

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sjavvaji:
Can't comment on the crashing but just wait a bit and click the back button and you should be able to get past the indefinite checking for updates.

I know this is not very important and should be low on the priority list for the rom, but is there anyway to have the playlist in the notification shade for Google play music? I know 14.1 showed the next three songs and it is a really cool feature
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Ilxaot:
This is on the developers of the Play Music app to implement I believe, and I think it's a design direction Google is running away from on Oreo (especially considering Google Play Music is being killed off).

As for OP, this ROM works well for me so far. Haven't encountered many issues although I'm still breaking it in (US996). If you need a tester for future builds let me know. Great work and I appreciate the effort you've put in.

So if you can reboot into twrp without pulling the battery, try getting this:.

Anyone attempted testing high impedance mode yet or tested if there is still a significant audio difference between stock and lineage, that is the only thing holding me back from giving this rom more of a shot is that lineage is significantly quieter through the jack than a stock based rom

Ok..new updateed h990. This is marked a "ds", but hoping that the dual will work on single sim too, just ignore the lack of a second sim. This is the same time, but new updated file, check md5:

9bc4bd0f59624616c40f4ef00904cf0e lineage-15.1-20180522-UNOFFICIAL-h990ds.zip

If things work out and we can do one h990*, then it will be only named h990 in the future for simplicity. Again...test... If booted into bootload, please try to reboot without pulling the battery (fastboot reboot), then in twrp:

cat /sys/fs/pstore/console-ramoops

Edit: I've pulled the non-working h990* from being downloaded.

This Rom is the only Lineage OS ROM that works on my H918, I really wanted to try Lineage OS 14 but the damn thing leaves my phone with a dim screen with flashes here and there. I tried waiting it out but after 15 minutes all I got was nothing new so I went ahead and dual booted this Rom (Lineage Os 15) alongside Super V20 and I love the ROM so far.

Thank you for saving what little dev work that is being done on this forum.

[MENTION=2881807]x86cpu[/MENTION] I've got the same problems, sadly. I mean hell, it boots and you should've seen the smile that came across my face when I saw the LOS boot animation start. I flashed the ROM, GAPPS Nano and Magisk to get started. In setup and post-setup parts of the screen would go black, and only some parts would stay lit (like if you're selecting a WiFi network, everything but the list of networks would be blacked out completely by the screen). Much like the 14.1 ROM on the DS, you can search for networks but I get the very same "Your SIM does not allow connections to this network" error. I didn't test camera or anything as navigating around with only part of your screen working is a bit hard. Let me know if you'd like me to do anything else, for now I've restored my stock backup.

But, it boots, and it's somewhat functional. It's closer than the last build was, and that means something.

I come here just to say that 15.1 is rocking solid in our V20 and the Oreo UI does look nice in our display as well as picture-in-picture feature, the GPS conf file in 15.1 also seems to fix the old problems we had in 14.1 with GPS, so GPS seems to be rock solid from what I have been able to test, the s5k2p7 camera sensor is working well.

New h990. This hopefully will work for single/dual sim. I hope to have resolved the screen flicker/fingerprint/camera. I am not sure about the Cell network yet, but made one adjustment so we can see if that helped at all. If things progress better, I will adjust and add the subject that h990 is now included.

Also, please as a helpful reminder, could anyone when posting about experience, let me know the variant as well. Ie.. h910, h918, ls997, us996, vs995, and now h990 (for that indicate dual/single sim). It is hard to keep track of everyone and which device each one has.

(Other builds are going now, so couple hours for those.)

Wow..wake up to alot of feedback, only the second day too. Hopefully the H918 issue will be straightened out. I'll try to reply the best I can.

Check if your MAC is all 00:00:00:00:00:00, if so, see post #1 for fix. USB/ADB has a panic bug.... need to track it down (known issue).

Sounds like the official to unofficial didn't go in right, error 7 is a generic assert error, meaning something does not line up and match.

I'll check into that, I use FAT32.

Great! I'll go with another H918 that "might" support PRE/POST 10P, we'll see.

Hmm... ls997 has always been a pain, will have to investigate more on that.

IR blaster was support to work, encryption is in progress, right now it'll completly toast your /data (internal included).

Cannot do that from a non-Lineage ROM, if so, you need to clean flash.
