[AShiningRay]

That's right! We're finally releasing the first 4.4 open beta, starting with Android 12.1 for G5, G6 and V20!

I'm the one of the main kernel devs on this project, so i'll be adding info on this part of the development and beta testing.

________________________________________________________

To anyone who wants to beta test this and the upcoming CRDroid rom by @ROMSG: We're using a dedicated github organization to handle feedback, bugs, trees and general development.

That organization is located here, with @xxseva44 moving the trees above to that same org soon:

LGE G5 G6 V20

Devices, vendor trees and new 4.4 kernel for LGE G5, G6 and V20 devices - LGE G5 G6 V20

github.com

If you have any issues that span across multiple roms using this newer kernel and updated device trees, or simply know that what you're facing is something that's bound to happen irrespective of a specific ROM, please open an issue in that org detailing the problem, your phone model, etc.

________________________________________________________

For a list of features that already work in kernel 4.4, we have a wiki page with just that:

Kernel V4.4 New _ Feature states in Android 11 ROMs

Contribute to LGE-G5-G6-V20/msm8996_lge_kernel development by creating an account on GitHub.

github.com

________________________________________________________

Kernel issues should ideally be opened here:

Issues · LGE-G5-G6-V20/msm8996_lge_kernel

Contribute to LGE-G5-G6-V20/msm8996_lge_kernel development by creating an account on GitHub.

github.com

Please note that this kernel is shared by the LG G5, V20 and G6, so when opening an issue, we need to know at least which device you're using, but the model (VS995, H872, etc) can give us more insight.


________________________________________________________

ROM issues will probably work best as xda posts for now, since those are already going to be separated by phone.


________________________________________________________

Quick primer of what to expect:

For the kernel: It's fast, really fast. Not only did we clean up tons of LGE code from the kernel trees, saving up a lot of memory and overhead, but also added lots of optimizations on top of a custom branch to make what's essentially a mix of @askermk2000's mk2000 and my own SwanKernel.

For the roms: We've been working with people from G5 and G6 as well, and in turn managed to do a major overhaul of the rom-side blobs, drivers and hals, resulting on much improved performance and stability, even during internal tests.

For issues: We didn't iron out all of the issues yet and are far from testing those things in a large scale, hence the open beta. We already have some known issues to fix, such as the much slower charge curve, usb OTG not being as fully fledged on the V20 as it was on 3.18, IR working slightly better than 3.18 but still not great, camera still freezing randomly... In any case, most of the other kernel features either work just like in 3.18, or better.


________________________________________________________

Known issues outside of Android 12 and 4.4:

Both TWRP and SHRP can have issues while flashing 12 due to incomplete support, so be careful and have a complete backup (including the recovery image itself) beforehand.

 

[xxseva44]

Performance on the initial build. No tweaks. Consider supporting the 4.4 kernel devs(@askermk2000 & @AShiningRay) as this is mostly thanks to their hard work and dedication, as well as insanity to do such a thing to an lg device. You can expect it to get even better as I iron out issues within 12, this score was achived with excessive log spam, looking at you radio.

 

[xxseva44]

Some kernel tunables I'd recommend changing to make your experience better:​

Change "down_rate_limit_us" from 10 000 on both big and LITTLE cores to 25 000 on the little cores, and 20 000 on the big cores. This will significantly improve responsiveness.

Change the minimum gpu frequency from 133mhz to 214 mhz, This will improve the ui rendering and smoothness.

You will obviously need root to change these.

These changes will appear in the next release which will likely come in the following weeks.

Did you even read the initial post?

 

[d2xTaimen]

Wow this is impresive...Going to try this out when I find my old v20

 

[koodz]

Hi this sounds like it could be awesome! Is there plans to get radio working so that the phone could be a daily driver with this, or is that not a focus?
Thanks for your hard work everybody!

 

[nostupidthing]

How to donate? Do you think you can fix the rest non Woking issues?

The issues will be worked out as devs get more free time. Hopefully we'll even be able to get A13 up and running at some point!

He's been busy lately but we have multiple devs looking into the radio and fingerprint and several other issues looking into the issue. Mainly it was due to the kernel needing to be updated to 4.4 (which we did) but that brought on issues, such as the radio. Just give it time and they will be solved in due time!

 

[xxseva44]

How to donate? Do you think you can fix the rest non Woking issues?

Theres a donation link in my about section on my profile As for the non working issues, They're easy to fix, although cellular is the only tricky one. Well that and the powered dock issue. However they should be fixed as time goes on.

Radio is currently the primary focus, however admittedly it is proving to be a tricky one.

What if you flash the modem into a US996 ?
Im saying that because my cellular network was not working on Lineage 18.1 and once i flashed the US996 modem on my vs995 everything was working for the DAC there is always the app to active it Dac fix app ons

here the link to download it : US996 Modem 10F IMG

 

[xxseva44]

What if you upgrade the modem into a US996 ?

here the link to download it : US996 Modem 10F IMG

The issue isn't with the modem image.

Update time
What's new?

-Fingerprint is now functional
-Dac is now functional
-October security patch

Keep an eye out for new uploads
All builds have been uploaded

Only radio is left is needed for me I think, what does drm does?

Drm is digital rights management. Required for certain applications and services, netflix for example.
