rk3188 CS918 CYXTECH, cannot get vsync patched kernel to work

[dmarkey]

Hi all,

I've been trying hard to get my rk3188 set up the way I want it to.

This particular task involved extracting the stock firmware(4.4), patching the kernel to fix the vsync problems.

I've successfully extracted and patched it, however when I use AndroidTool to flash the kernel, the box goes into a reboot loop with the android with the spinning box chest.

The strange this is that if I flash the unpatched kernel again the same behaviour continues.

Any ideas?

(I've also tried to pack the kernel into a full image using imagepackrrk but that didnt work either)

Need more information on the board.

Also, any reason why you arn't using d33's kernels?

This is my board:

This isn't a kernel problem, as if I flash stock kernel, then the boot loop still occurs.

Did you try Wasser KK 1.0.4 for CYX_CS918 V2_3? what were the results?

[dmarkey]

I think I did, but it took 10+ minutes to boot.

Each time?

Might be easier to strip parts of the rom out to speed it up, as I'm unsure what could cause it randomly not work after a flash.

Sounds like an awful board.

[dmarkey]

Yep, and randomly the ROM would go into recovery.

Why do you want to vsync patch a KitKat kernel?
It's only needed on Jellybean Kernels and not compatible with KitKat kernels, since they already use updated HDMI drivers.

Didnt know that!

I'd like to overlock it anyway as i'm stuck on 1.4 ghz
