[Kernel][VS995][10b] reStock - a stock based kernel for V20 VZW V1.4 2018-03-05 - LG V20 ROMs, Kernels, Recoveries, & Other Developm

OK, here I go. I started this for self edification and to get my Version V20 on a stable kernel with no static on boot. I started out with the open source from LG for the VS995, in this case 10b. I figured this would be the best starting point and it seemed to work well. From there added what was missing from other kernels that I needed. I figured I'd share the results. I may add more features, governors, I/O schedulers, KCAL possibly, etc. at a later date. I'll take feature requests but the goal is to keep it simple and stable and I'm not much above a novice when it comes to tinkering with the kernel so bear with me.
I don't plan on supporting other variants and don't know if this kernel would work on any other variants.
Features so far:
No static on boot.
exFAT support
LZ4 kernel compression
Remove verifiedbootstate flag patch
KCAL support
Noop, Deadline, CFQ, FIOPS, SIO, BFQ and Zen I/O schedulers
Cubic, Reno, BIC, DCTCP, Westwood, Highspeed, Hybla, HTCP, Vegas, Scalable, LP, Yeah and Illinois TCP congestion control algorithms
ElementalX, Blu_active CPU governors
Adrenoboost (from @flar2)
RCTD, CCMD, and Triton removal (based off of the script from @Zacharee1)
WireGuard VPN
Changelog
V1.4 3/5/18
Added WireGuard (thanks (again) to @poixninja for this one)
V1.3 - 12/8/17
Added Adrenoboost GPU boost
Added RCTD, CCMD and Triton removal script to installer
V1.2 - 3/29/17
Added ElementalX and Blu_active CPU governors
V1.1 - 2/28/17
Added FIOPS, SIO, BFQ and Zen I/O schedulers
Added DCTCP, Westwood, Highspeed, Hybla, HTCP, Vegas, Scalable, LP, Yeah and Illinois TCP congestion control algorithms
Added KCAL support (thanks to @poixninja for this one)
V1.0 - 2/14/17
Initial release
Note on installing: I recomment using TWRP 3.2.0-0 for the vs995 to install this kernel. The 3.1.1-0 version generic 'elsa' release does not work for flashing some custome kernels, including this one. TWRP 3.0.2-1 for the us996 will also work.

Wow! Glad to see someone doing this! I am currently using the konverged kernel just because of how well managed it is and what It has. Im unsure if its possible, but do you mind looking at what it has and see if you could port those things to this kernel? I have no knowledge of how to do this or id already have done it. The battery life itself makes that kernel amazing. But it has the static boot :/
Edit- I'll most likely test it here soon! Currently can't but I'll get to it xD

---

Wow good job man, I'll test it out and see whats up. Thanks

If there is any difference it may be in some core control code. See if you can give me some sort of ballpark guess at how much of a difference there is between the two and I'll look into if I can implement it.

It works on 3 V20s I've tested it on so this is the first failure I've encountered. I guess we'll start with the basics. What screen does it die on? Are you on a VS995 or another variant? What rom are you using, I've only had stock to test?

Well I'm just meaning the things that is has implemented into it. I couldnt even give you a ballpark guess on how different they are sadly. I have no idea how to edit kernels for that matter. If its too much trouble then idk xD Sorry for bothering you then lol

I'll certainly look into it and do what I can. I'm also looking at I/O schedulers and possibly governors to get better battery life/performance but my goal is to make sure I don't break anything. I'm learning a lot on the fly here so be patient. Battery life seems OK so I don't want to jump into things too quickly. I only had my device and 2 others briefly to test it on and then I'm pretty sure there is a lot that hasn't been tested.

Yea no worries! The konverged kernel might have those. I get like 16+ on debloated and greenify governing and 12+ without it so it must have something like what you are looking for. Currently I have a VS996 on Weta US996 with the konverged kernel. So I will test this one out as soon as possible.

So no static on boot ? Just flash via twrp?

Yes to both. Due to the one report of it not booting I would make sure you have a backup on hand.

Do you by any chance have su hide flashed? I had the same thing occur to me while updating my kernel and rom. If su hide was installed and the kernel got changed, it would refuse to boot. Just a suggestion if you do have it installed, I advise to uninstalling it first.

Ok so not sure if i did something wrong but for some reason this kernel wouldn't boot up for me. I was on NRD90M Modded NotSoStock Rom for the vs995 with the Konverged Kernel. I did a clean flash and restored my backup from TWRP and reflashed the new kernel but no dice. Maybe I'm doing something wrong?

Yeah I do have SU hide installed. I'll try deleting it. Thanks

Su Hide repacks your boot.img (kernel) so half of it would be installed and the system wouldnt be able to boot properly. So installing a new kernel with su hide already installed will just cause a bootloop.

Just removed SU hide, and reflashed booted up with no static screen. Thanks again. Now to try this baby out.

You should be able to reflash su hide! Just make sure to uninstall it before switch to another kernel!

I sure hope you go the long-haul on developing this kernel. VS995 sorely needs some love lol

Thanks for helping troubleshoot this. I have not had time to test and root cloaking although I was asked to put in the patch to bypass the SafetyNet CTS test by a friend who hasn't reported if it even worked or not. It's on my list of things to try, I'd like to use Android Pay, but I have other things I want to get to first.

In for a penny in for a pound as I always say... or at least when I'm using a fake accent to try to pick up chicks. Anyway, I own a V20 and will probably have the device for a while. Unless something happens to it or other developers can put more effort into it, I'll do what I need to to get my device to work as I want it. Beyond that I am open to suggestions.

By chance have you seen anything missing in the kernel preventing Wi-Fi calling? Mine says Wi-Fi calling is on but when you place the phone in airplane mode and turn on Wi-Fi it says can not make call in airplane mode.

I believe you just need to go back into your settings and re-enable wifi, airplane mode disables it by default. I tested wifi calling this way was tested and it should work fine.

I have done that, I turn on airplane mode, turn on wifi and try to make a call and it says it can not call in airplane mode. Stock it would make the call and show its in WiFi calling
