NEW - 1080P kernels for Finless KitKat 2.0 ROM

[mikele]

Hey Bob with your distrib and your kernel_cpu1800h_gpu798h_ddr720 I clock my crap T model CPU to 1,4GHz
woooooooooooooooo
its crap RK3188-T model clocked to 1.2GHz stock on GK525.
What do you think about that ?
All other kernel gave me only 1.2GHz speed
Well, I can see the CPU speed with CPU-Z but do you know how I can check the ram / gpu speed ?
Regards

@Bob
I see you in this forum http://www.freaktab.com/showthread.p...d=1#post139318 and that TVDroid, Pet2001 and SanDroid can have 1.9GHz CPU clock with "Neomode Rom" and "1080p Oc Sam kernel" on their "T" model (jelly Bean 4.2.2).

Can you do the same for KitKat ?!"/$%?&*()_

Regards

No matter what kernel I install, 1.4 GHz is what I get maximum on my 908ii (according to set-cpu or cpu-z). Is this a bug or a feature?

NEW - 1080P kernels for Finless KitKat 2.0 ROM

You have an RK3188t which is physically restricted.

Dude you have to get reading here http://www.freaktab.com/showthread.p...-of-RK3188-CPU and try the neomode rom with sam kernel thats sound 3 people have 1.9GHz CPU clock Speed with their "T" restricted model. Good luck.

Finless, d33: what would you say are the main differences (if any) between these kernels and the latest ones posted by d33 in the ROM's thread:

If you open your eyes
you will see that d33 kernels are latest builded kernels from february 24 for "RK3188-T" and not "T" chipset / AP6210 and AP6330 device. 1080p and 720p. The finless kernels builded january 15 are older / already patched and not made for "T" chipset or AP6330 specificaly . It include 1 kernel stock.

If you read the forums
about this kernels you will see that d33 kernels are not patched and there were also improvements about the USB / LAN and the external memory partitions. You have to patch this kernels with rkpatchomatic.

May be there is some other little differences

Hi. Can anyone help me. I cant use any of the over clocked kernels. It booted up once then reset to the linux penguins. Works fine with stock though. Dont think my cx919 is the t version because ive had it awhile, i might be wrong tho. I ran an app it say it wasn't the t version. Opened it up its ap6210 tod6002 1324. Running at 1.6 ghz works fine when I flashed an .IMG file jellybean ROM. I'm tearing my hair out ready to throw my stick at the wall. Thanks in advance. Rob

Hi

Thank you sorry double post

Hi Finless,

what are the hex values to change in the kernel binary to convert it in 1080p?

Thanks

[smic717394]

Hi Bob,

Can you please help me patch the MK902 720p kernel, can you please share the hex that needs to be changed to convert to 1080p pleaseeeeeeeee. Or can you patch the stop kernel to 1080p please.

Thank you.

Hey all!

Today I figured out how to patch 3.0.36+ KitKat Kernels to 1080P!
The code for these changed for 3.0.36+ JellyBean kernels.
I have to tell you, to figure this out requires decompiling the kernels and finding the code.
Not easy and full of PAIN

Special thanks to FreakTab developers darrellr and Wasser!
They provided me kernels to decompile and compare thus finding the patch locations!
I could have done it otherwise but it's a lot more work.
So THANKS guys!!!!!

So you might ask.... Why patch stock kernels?
Well... believe it or not, SOME people want stock because they know it came from the Manufacturer
and was not "public" generated. I know that sounds silly but this is why I spend the time patching.

__________________________

So in this download are:

1) A stock Tronsmart kernel patched to 1080P. Nothing else.
Now understand why the stock Tronsmart kernel gets low Antutu scores!
It is clocked to 1200 CPU only and DDR is also under clocked compared to JellyBean kernels.
I don't know why they did that but this is why it's a BETA release from them,

2) A full set of Over Clocked kernels patched to 1080P.
Again these are stock Tronsmart kernels patched to 1080P.
Then they are OverClocked using Mr. Andersons patch-o-matic scripts.

I find for the CX-919 the kernel:
kernel_1080oc_cpu1608h_gpu600h_ddr667.img
Gives me the best trade off of heat (with no worry of frying your stick) and performance.
This is true for the 720 kernels I already provided in my ROM.
This gives me an Antutu score of 17000 for a 1080 kernel.
A 720 kernel of this same OC gives 19000.

I think it is also safe to use:
kernel_1080oc_cpu1608h_gpu600h_ddr720.img
But depending on your stick you might have stability issues. Still no fear of frying your stick though.

It's when you go above 1608 and GPU over 400 do you start to worry about heat.
Thus if you use these higher OC kernels please consider cooling and heat sinks.

__________________________

Instructions:

There is NO NEED to erase NAND and reflash the entire ROM!
Just use the flash tool from my KitKat ROM kit.
One the kernel line click the far left empty box and point your file browser to the kernel you want.
Flash that ONLY e.g. uncheck everything else in the flash tool except the kernel line.

I cant patch the kernel and I tried before. It is coded differently than any other kernel I have patched before. It would take more time than I want to spend to figure it out all over again.

Now you can find it yourself but it's a PAIN. This is exactly how I have done it!!
You have to decompile the kernel into text then looking through raw object code find the 1280 and 720 areas. Note the address location then go patch the binary at those locations.

To decompile a kernel you need 64 bit Ubuntu installed.

First unpack the RK header from kernel.img so you have kernel.bin

The command to decompile in Linux is:

/usr/bin/arm-linux-gnueabihf-objdump kernel.bin --target binary -marm -D > kernel.d

Kernel.d will be a huge text file.


Some tips would be to decompile 2 exact kernels with the only difference being 720 and 1080. Compare the 2 decompiled kernels using kdiff3. You can then easily find the locations between the 2.


Good luck!

Bob

how do i umpack the rk header. ?
