[KERNEL] ezV2020 Kernel [PIE][OREO][Stock] - LG V20 ROMs, Kernels, Recoveries, & Other Developm

Info
This is a stock based kernel with basic fixes only, i.e static screen fix and added color controls. A pure stock experience without any further enhancements. It is a one-off release, although I may fork it and add some minor features later in a new version. This version will stay fully stock with fixes only.
Why this? In my case custom kernels caused some negative issues. For example I like to connect my second device to my TV using a usbc hdmi dock. This would not work on custom kernels without problems, but does on stock, so I decided to fix this. Others have also reported performance issues I wasn't aware of. Hopefully these are fixed also.
Features
Stock kernel based on US996 Oreo sources (20f)
Dirty Santa fixs applied - Static screen on boot fixed & dual sim issue.
RCTD/Triton - disabled
KCAL added - color controls to fix image retention issue
DYNAMIC FSYNC - faster write speeds due to less error checking thus increasing performance. Toggle on/off in kernel manager.
Boeffla Wakelock Blocker - This does nothing in itself - it just shows a list of wakelocks in your kernel manager that you can now disable.
USB Mass Storage Enabled for DriveDroid.
Installation:
Back up your current boot in TWRP if you wish to easily go back to your current boot.img.
Flash *.zip in TWRP.
No need now to flash magisk as was the case with the beta version.

Thanks for this ?
2 questions.
1)
> ForceEncryption" and "dm(avb)verity" removed
What do you mean by this? This can be set by Magisk, do you mean that this sets it to off or removes the ability to set it completely.
2)
> Magisk 20.4 included (for now)
Why is this, I guessing it's related to question one.
I have an official unlocked US996 so I am hesitant to test this but I will post here if I do.

1. Set to off, both.
2. Why is it included....just for convenience. If anyone needs it removed you can just use the magisk uninstaller.
I see no reason why it won't work on official unlock us996 now that I think of it. Give it a try and let us know. Just backup your current boot first.

I'm running it tonight on my H910 with a stock-based but heavily modified Oreo ROM. Switched from MK2000 2.1 beta 34 for the evaluation. Seems to be running fine as far as I can tell so far.
I'll update my status after some run-time. US996 is the same hardware as H910 so the kernels should be fairly interchangeable with similar OS versions.
It's also a best practice to clear cache in TWRP after switching kernels so you may want to add that to your install instructions.

I am wondering if anyone would like to volunteer to test the dual sim functionality of the H990DS. DM me if you would, tks.

No, you must restore your origional boot partition now.
Please read the OP in full. The thread title states it is for US996 only for the moment.

Hey, I got an H990DS and willing to test for you. Just tell me what you need

@ezzony..can u plz guide me on using Toolchain as i wanted to build the kernel for h918 for MIUI 11ported from MI5 to Fix WIFI driver not loading
...which toolchain are u using plz guide
As i tried Linaro as well as Uber ...both failed to build zimge
I am building using mk2000 source

I was unable to build mk2000 using the toolchain that was said to be used to build it. You will have to ask the mk2000 dev. I would be curious to know this as well because I tried a few versions of Linaro including the one he said he used but it always failed. I built mine from the original LG source.
Lets leave that there as it's a bit off topic for this thread. Contact me by DM if you have any further query in relation to your issue.

Oh no problem. Btw I'm a noob at this so my knowledge is limited at this stage. I do have a suggestion for you though, I'll DM you.

This kernel is not for the H910, I know that; however, I've been testing it heavily for the past 2 days without any major issues. On my H910 though, it corrupts the MicroSD card; It gives me a "fix your SD Card" error and crashes if I try to fix it by formatting the card. I went back to the original BOOT partition and the MicroSD card works fine. As of now, it works pretty much the same as the mk2000 version 2.2. I have installed.
I probably shouldn't be giving any feedback as this kernel is not for the H910, but I want to make sure whether the "card fix issue" is an isolated situation or not. If it is, then there shouldn't be any compromises when testing it on the H910 as well.

The difference between us996 and h910 kernel are minuscule, if fact the differences' are more like 'setting's' than anything fundamental. I recall seeing something about 'crypto sd card' in the config files for the H910 so I'd be 99.9 percent certain the issues is caused by this not being included in the us996 version.
I was waiting for some feedback before I compiled the rest of the variant's ( in case there were any issues or I thought to add something more) but I'll do H910 to make sure this issue with the sd card is fixed. I'll be putting it in a flashable zip this time, perhaps you wouldn't mind testing it for me before I release it fully. I'll send you the dl link by dm in any case when it's done, hopefully later today.

I restored my TWRP backed-up BOOT partition and my MicroSD card worked again. I then flashed the "ezV2020_us996_beta1" image from TWRP, and got the same "SD corrupted tap to fix" message as before. Went back to TWRP and installed the "H910_ezV2020_beta_1.0" zip file, followed by Magisk, then wiped davlik/cache and rebooted. I'm still getting the "SD corrupted tap to fix", and Magisk uninstalled from my phone and won't install through TWRP or manually from the Manager anymore. I had to restore the boot, system, and data partitions from a TWRP backup to get everything up and running again. I should have mentioned I'm using Alpha Omega Oreo, but since it's a Stock ROM, I assumed it was compatible.

Sorry this has caused you a headache.
I have looked into this and can say with certainty that the issue is that your SD card is formatted in a type that is not supported by stock kernel i.e most likely exFat. Support for exFat would have been added to the custom kernel you were using. I have tested this myself by formatting a spare sd card in exFat and got the same 'corrupted' error. My own SD card is formatted in Fat32 and works fine with ezv2020. Therefore anyone who does not use exFat SD card will not experience any problem.
I do not know what caused the Magisk problem but it can be a bit funny sometimes. Glad you kept a backup handy.

H910 version is up, link in OP. It is a flashable zip this time, not an .img. Flash Magisk and wipe davlik/cache before rebooting.

No worries. That's what testing is for. I've almost bricked my phone hundreds of times, so I'm used to restoring to stock and rooting again. And yes, I always format my MicroSD cards as exFat; I have a few 6GB mkv Movies on my card, so I kind of have to.
But unless I'm mistaken, the Stock kernel of the V20 should be able to use exFat. As I stated before, I've been on the brink of rendering my phone useless for messing around trying MODs and stuff many times. The only constant has been my MicroSD card formatted as exFat; I've ended up with a Stock H910 on Nougat and Oreo plenty of times without removing the card, and it's always readable. I don't want to state that as a fact because it's been a while since I've fully returned to Stock and re-rooted, but that's what I remember, my exFat formatted card working with Stock unrooted Nougat and Oreo. Maybe someone can confirm that, and if I'm wrong, then I'm sorry.

It seems it was me that was mistaken. Well I said I was only 99.9% certain
I have fixed the issue. Could you confirm when you have a chance. Also wiping davlik cache seems to cause a weird issue after reinstalling Magisk. I tried again by just just flashing Magisk and that was fine, so don't wipe.
I'll update US996 when I have a chance.
