I uploaded the new build (lineage-20.0-20230128-UNOFFICIAL-clover.zip).
Use sec_access values from 4.19 kernel.
Please test the charge.

Btw: twrp-3.7.0_12-0-clover-4.4.img works great!

The new build still stop charging sometimes.
I think it's better to use the code from xiaomi's source code:

sec_access = (addr & 0x00FF) > 0xD0;

I created the boot.img with your suggested code. Please flash boot.img with fastboot and test this boot.img.

I have the Wifi version, does this rom still suffer with the battery drain bug? I currently have to stay on P rom to avoid that bug

It's strange. I still get this issue for this boot.img.
But I modify the kernel code, and make a boot.img by myself, this one work fine for my mipad4.

Thanks for the reply, but after a few days I found no battery drain like most a10/11 roms

Could you provide a diff-file of the kernel source?

For decrypt support of A12/13 FBE (file based encryption), TWRP 3.7.0_12 (12.1 branch) is required. The official TWRP 3.6.2_9/3.7.0_9 is 9 branch that doesn't support A12/13 FBE. The kernel version doesn't matter.
For switching between my LOS 19 (no encryption) and my LOS 20 (A13 FBE), formatting data is required.

Hello,

I am currently on @sabar_op's LineageOS20. Suffice to say that I am currently on the 4.19 based TWRP 3.7.0_12 by @pix106. So I have couple of questions regarding your android 13 ROM. This was also suggested to me by someone who replied on my comment on another thread.

is my current recovery OK for flashing this ROM?
Does this ROM support USB audio? Because Sabar's LineageOS20 (and I think his pixelexperience30) doesn't.

I am not saying sabar'sabar's ROM is bad. I just wanted to use my USB DAC. Lol

Please use twrp-3.7.0_12-0-clover-4.4.img in the first post.
USB earphones seem to work. Please test it.

Maps Me don't work well with this rom

bakasamaz · Feb 11, 2023

Does anyone here experience an issue with the taskbar? somehow after putting my sim card and receiving mobile signal, the taskbar is no longer showing up both in portrait or landscape. Also, Google map doesn't show toggle for dark mode. Would appreciate the help here. Thanks!

Filippo21 · Feb 11, 2023

Hi, I just installed the ROM updating from LineageOS19 using Lineage Recovery.
Everything seems to work well.
The At A Glance widget Is not available on the home page and I can't find it on available widgets list. Who knows how to add it?

Great ROM! Thank you very much to the developer!!!

browoz · Feb 11, 2023

This ROM looks really neat, but I am wondering is USB MIDI support enabled? The device seems to have no trouble running USB host mode with stuff like keyboards but it cannot talk to any MIDI device (tried a few).
@kyasu would you be able to enable midi support in the kernel?

This one still has problem for charging.
I found the reason, there're 2 position need to change for 0xD0, the above patch just modify one.
We need to modify the code of fg_write() and fg_masked_write().

I uploaded the new build (lineage-20.0-20230212-UNOFFICIAL-clover.zip).
Android security update date is 2023-02-05.
Merged twu2's charging patch.

addidub · Feb 14, 2023

@kyasu just passing through to say 'thank you' for all your works to keep Clover alive with your lineage os forks. I am using lineage OS on my Mi Pad 4 since 2019 and it has never let me down yet.
Today I installed your newest version and everything I tested until now is working like a charme. Unlike many other devices I owned, Clover is able to run GTA San Andreas app which is very nice
