If you also want to run LOS with a Custom Kernel, you may also install the Custom Kernel below:
JimboK-LOS KERNEL
Features:
Several EAS commits for balancing power+efficiency
Fsync On/Off Toggle
Dynamic Sync Control
SLIMBUS OC to improve the Audio Mods
BBR2 TCP Congestion algorithm by Default
Added IO-SCHED drivers like: ZEN, FIOPS, MAPLE etc...
KLAPSE Driver (check out https://forum.xda-developers.com/and...odule-t3907025)
KCAL Color Control Driver (Up to date)
Boeffla Wakelock Blocker Driver
Adreno Boost
Enabled a few drivers inside of Kernel: CDC, NTFS, CIFS and some native gaming devices as well
Added and Enabled HID: NINTENDO SWITCH controllers support
Enabled ZSTD Compression, it is recommended to enable this for ZRAM moving forward
Disabled LZO, updated LZ4 compression algorithms
Several Upstreams to NET/TCP in order to improve Network Connectivity and Speed.
Added a fix to hide Magisk Mount for Isolated Processes. This is a critical leak in MagiskHide that can be exploited by apps trying to determine if the device is rooted. I had an issue with two payment apps that after applying this fix, they work. Not sure if they were finding magisk with this method lol.

Yes we just need a tester. Neither @ChongoDroid or I own a S20+ so the support in kernel is there but need testers

---

It should work though on s20+, I wonder if FHD density is the same as ultra. Also finger print placement might need testing.

No no, I mean you could build lineage with our code for S20+ and it'd flash and work fine.
We've only been building for our devices but the trees from lineage have support for S20+.
We'll think about it, maybe I'll build an alpha build for S20+ and see if how it is.

No. That's not gonna work, it won't boot. What he says is we can build with the same parameters since we are forcing [email protected] the resolution and assets need to be adjusted.
Jesse's trees are configured to build at [email protected] so we need yo move stuff around to make it work at FHD+

The way gesture navigation is supposed to be.

No. Previous OneUI 2.1 vendor is needed. I believe all ROMS with AXXX are 2.1 (July and prior). One UI 2.5 vendor will not fully work and those begin with BXXX I believe.
