[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Omar-Avelar:
I actually keep things at my pace. Where as [MENTION=4662457]Rashed97[/MENTION] and [MENTION=2881807]x86cpu[/MENTION] are very quickly at integrating and merging the Android and Kernel sources into the Stock LineageOS Kernel sources. (So my Kernel builds are "stuck" with what most likely be the version for Oreo release for the V20 aka 3.18.71 which was the CAF release for msm8996 for January for Oreo... and will get updated further down the road... just not as fast in that sense).

I try to keep my Kernel tree separate than LineageOS but the dtsi 99% the same, so that we can find common bugs or also have comparison points between Kernels (since there are not many V20 devs) so I like doing it this way, I am more of a slow adopter (except when absolutely needed such bringing up the Kernel into Oreo or big merges need to happen, which was the case for this month on the 15.1 Kernel).

I believe with v5.0.0 I have reached the stabilization point with the Kernel where it all works smoothly. Now, I want to say a few things about the v5.0.0 version.

The wakelock source blocker had to be carefully tailored to fit our V20 needs, the masked sources are as follows:

wlan_scan_wake;wlan_oob_irq_wake;wlan_evt_wake;wlan_wake;[timerfd];NETLINK;IPA_WS

Hoping this serves for reference and documentation. So it took me a while to figure out that the Broadcom drivers being used for our kernel (BCMDHD) use something called NETLINK for IPC (inter-process communication) to send commands to user-space. This has a wake-lock associated with it and hence why when the wireless stack was enabled it would not idle as great as it could. This "bug" is horrendous for idle battery life consumption, but it is not a show stopper since functionality was working well.

Seems like not all of the Android wireless drivers are coded the same, but at least BCMDHD which was choosen as the driver for msm8996 LGE's common source does use Netlink and hence why silencing this thing up as well as some other associted wireless wakelocks seem to be proving beneficial.

Just disabling NETLINK wakelock was no good as this would clash with other wireless wakelocks and end up missing network packets, so hence why I had to disable a few others. After testing I think I nailed it. :laugh: Hope you guys enjoy...

Thank you so much for clarifying. I was wondering about that. You do good work, Omar
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Omar-Avelar:
v6.0.0 version is up, there were some remnants of 6a00000.ssusb wakelock that would trigger from time to time. I have fixed those now. Also we have improved deep sleep based on common work by [MENTION=2881807]x86cpu[/MENTION] and me ;)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Omar-Avelar:
v7.0.0 is now up with some more experiments to get better deep sleep, let me know how it goes ;)

How would you rate deep sleep now? Here are 3 screenshots from the CPU times section of Ex Kernel Manager.

This x1000. If we can use the earthing plug-head on a wall charger to "restore our natural electrical connection to the Earth" then surely we could come up with a way to dump the heat into the same plug-head and away from both the device and charger.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
As per this Quick-charge table

1.5A isn't classed as quick-charging for any generation.

The SD820 supports up-to Quick Charge 3.0 which does up-to 2.6 A or 4.6 A/8 W (9 V * 2 A). I believe this is just above where the stock V20 charger does out of the box (mine is 2.5A with the fast-charging logo and info displayed on it).

I've only ever seen a maximum of ~2440mAh when quick-charging, so if you can get hold of a 2A quick-charge charger then you'll see a noticeable improvement in charging times.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
I have had almost 3000, about 26-2800 or so when using my stock battery and about 2400 when using my 6600 mAh battery, so I guess it is capable of fast charging.

So if 5V-1.5A isn't fast charging it must be the 9V-1.5A then.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
That's likely the case, and is more-than-likely because 5V@1.5A isn't enough to drive fast-charge's minimum requirements, hence the extra voltage needed.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Grin59:
So whenever I turn on Live Display I get red-orange screen retention that's worse than the normal screen retention, screen retention is definitely reduced since using this kernel but I can't enable the warm toned filter to reduce blue light without getting screen retention. Hopefully Omar can fix this.

Did you try reducing the stock rgb values for about 5 to 7 % it helped me with my screen retention while using the kernel adiutor rgb settings to calibrate my screen and maybe it will help you to on the rr rgb settings.

What i belive is that the implementation of the stock screen calibration is a bit incorrect. The screen might be put in an overpowered mode instead of just the stock screen calibrarion when leaving the sliders at max. (in the stock screen settings and aswell in the kernel manager rgb settings.)

Hello Redline!

Since Omar switched to developing gamma kernel for Pie-based ROMs can you please compile his latest v74 build with second screen option?

Thanks!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
AFAIK Omar hasn't switched to exclusively developing the Pie version of Gamma. Last I heard both were being worked on at once, and in fact the Oreo-based Gamma has had a few updates since his Pie betas were released in the LineageOS 16.0 thread.

His Github repo hasn't had any activity for almost 2 weeks now.

A lot of the notable V20 Devs are going through a quiet period in terms of activity on XDA, but that's okay, everyone needs to manage their time.

The last build I did was based on v71, changes up to and including v74 haven't been significant enough for me to warrant getting an updated build out ASAP. Like always, if I find the spare time for it then I will, but otherwise as it stands v71 is still recent-enough if you ask me.

I actually only just recently updated to v74 from v70 myself.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
True that Redline.! I've been running the latest 15.1 with v71 SS and getting amazing battery, performance and speed. Absolutely zero hiccups. I tried v74 just out of curiosity to see if anything jumped out but nothing did so for me, the SS is worth the sacrifice that I can't even notice. Thanks buddy. One thing I recommend to anymore interested; stick with the stock launcher. Others don't play as friendly imo.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] inspigr:
Hi all,

I am sorry for the inconvenience.

I have just root my LG V20 H990ds and i'd like to install a new ROM.

Where can i get the "latest 15.1 with v71 SS"?

Best wishes!!!

-=-=-=-=-=-=-=-=-=-=-=-=-=-
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Under the LineageOS 15.1 downloads folder there's stock LOS second-screen enabled builds, but I'd recommend the ResurrectionRemix second-screen builds personally, as they're much more up-to-date than the latest LOS one is.

You'll have to search for it in the ResurrectionRemix thread, but it's not hard to find.

You'll need my second-screen v71 kernel download for the H990 at the bottom of the page.

Flash the ROM and then the kernel, followed by any system modifications like Magisk/Xposed/GAPPS/Etc. Wait for the first-time boot for a bit and then you're good to go :)

Every now and then I update the second-screen builds with changes that Omar makes, but currently he's not too far ahead of v71.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cityneversleepz:
[MENTION=5988026]Redline[/MENTION] I'm using lineage 15.1 (non second screen...12.14.18) and your v71 SS on it. LS997 is working great that way. Just wanted to clarify that. Can't use RR because the RUIM/SIM issue is impossible to overcome. Ty
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] inspigr:
[MENTION=5988026]Redline[/MENTION]

Can you please suggest me a version?

I have already install:

RR-O-v6.2.1-20190131-h990-Unofficial.zip

and

gamma-kernel-SS-v71-h990.zip

and

Magisk-v18.1.zip

but i don't see anywhere Google Play and the Second Screen doesn't work either!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
I've read that lineage is quicker and smoother than RR but less customizable, is this correct?

Thanks
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Because you didn't install the second screen version of that ROM.

Search the thread for the second screen version download and flash it, then flash the kernel again and Magisk.

Then you need to flash a Gapps package from OpenGapps (can be found by quickly doing a Google search) since LineageOS doesn't come with it installed by default.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
RR bolts on additional customisation over stock LineageOS so it's always going to be a touch behind, but it shouldn't be anything noticeable.

I've only ever used RR when testing kernel builds, I use LineageOS 15.1 as my daily driver and it works perfectly fast and responsively, even with fairly conservative governors set.

I've not noticed anything out of the ordinary on RR.

None of the customisation that RR offers interests me, personally.

RR is a LineageOS-based ROM, so it shares almost all the same code.

In the case of the second screen builds though, RR is more up to date.

If you want to give LineageOS a try, I'd suggest a simple TWRP backup and clean flash to LOS when you've got the time, having a TWRP backup ensures you can simply wait 10 minutes for a restore to your original working setup.

It's up to you personally, in the end. If it doesn't look like LineageOS has customisation options that you like (and there's no alternate way to get them) then I'd stick with RR.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] EnterTHEvoiD:
I've been using RR since first rooted the phone and have enjoyed it quite alot it's just that sometimes it has some hiccups. Maybe all it needs is a fresh install of the rom and Gamma kernel.

just out of curiosity, which app are you using to adjust the governors (last time I messed with governors was when I had my sony Ericsson Live with walkman :laugh:)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Kernel Adiutor.

As Gamma is an EAS kernel you shouldn't really mess with the governors, but that app does work quite well for doing most things kernel related.

I've managed to use conservative on the Big cores and interactive on the LiTTLE ones with good heat management and a balance of battery Vs performance.

No guarantees here, but try using KDZWriter and the latest v10x KDZ for your region to update your /modem partition, then re-flash Gamma.

Updating the modem partition from newer KDZ versions (but not v20x ones because that breaks it) has solved various issues for people.

Hi, question about the Gamma and gaming. I did some phrase searching through this thread about performance and it seems (to me at least) the EAS is adaptive to the processor need - or, in other words, it's not a tweaker kernel, but more a set it and forget it? I'm interested in pushing the V20 to be a contender in PUBG and wanted to know if I need to set a profile up for those times etc. Thanks.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Redline:
Nope. Set and forget.

If you're looking at pushing the V20's performance, you'd want to be exploring the updated Adreno drivers thread, and look into removing the thermal limits of the device.

In doing so though, you WILL shorten the life of your phone.

Oh shoot, what about v78 and infrared? I think I might need to check what I might have messed up...

Btw, I think I was able to make v78 even more smoother by backporting a few BFQ changes, and adjusting the memlat frequency tables even more. It feels great!!

NOTE: I have now replaced the perfd binary with a dummy binary and have done in kernel event EAS boostings now. This should now also allow you to mess with max and min frequencies at will using any Kernel adjustment application of your choice without perfd going nuts! ;)

On another note, I just wanted to let people know that I've recently moved to a v30+ as my daily driver.

Through an eBay bulk deal, I was able to get one for less than 300 USD brand-new with stock local to AU, and a full 2-year warranty. My specific phone even turned out to be from a recent Feb 2019 batch.

I was rooted and had LineageOS 16.0 (there's plenty of LOS ROM variants available, but I like the mainline one) with GAPPS and everything else setup and stable in less than an hour of having the phone in my hands.

Rooting the V30 family is a lot easier than the V20 (not making a direct comparison here as they're different families of phone, merely stating) and it's also a much faster, fluid and modern experience overall.

I can safely recommend it to anyone looking for an upgrade, or even a stable Pie-based custom ROM experience.

Android Q is just around the corner, the Pixel 2 already has preview images going online, and who knows what that'll bring.

On a slightly more personal note, I still have my H990DS V20 with LineageOS 15.1 and Gamma on it, but there's no guarantee of continued development of GammaSS from my end. Personal life has gotten busier for me as of late (both on and off XDA), and if I find the time to get my build environment going again (I lost my previous one as well as all the files for GammaSS) and setting up things how I had them, like the Makefiles specifically, I'll get them all on a repo so anyone can clone it and continue it if they'd like.

It's a relatively simple process, and there'd definitely be a way to automate it as well as Omar does his stock Gamma builds.

I'll still be around the V20 section, maybe just a tad less-so. It's one of if not the best communities I've had the pleasure of being part of :cowboy:
