Here are the steps.

Option 1: Reflash a complete ROM
1. Take Finless Bobs 1.5a firmware suite
2. Extract the same on your linux/windows
3. It will have a directory FinlessROM
4. Download kernel.zip attached elsewhere in this thread.
5. Extract kernel.zip and place the same in the FinlessROM directory (replacing - the original kernel image file - take backup of the existing file)
6. Fire up - the RK flash tool (found in bobs, 1.5a suite) - on windows...

7. Follow all the steps as it should be loaded... and you will have a 1080p resolution device with Finless ROM

Option 2: Shorter - kernel reflash only
Follow steps 1-5
6. In the RK flashtool - uncheck everything else, except the kernel image (this should remain checked)
7. Flash as you would using the RKflash tool.

You are set !!

All the best.

It's not much different than the last one except it has any cpu speeds over 1416MHZ removed.

I'll also have the 1416MhZ 1080p MK808 beta 2 rom up in the Firmware section in a couple of minutes.


Hi deadhp1,

Thanks for the kernel, I tested it and really like what I'm seeing.

Is it possible for you to make a 1608mhz 720p kernel? no scaling to 1080p?

Looking forward to your work!

I'm building it for you right now, then I just need to make sure it boots.
I personally won't be able to test past 1416MHz that because my MK808 likes to crash at 1608MHz.
I'll upload it in a bit.

Ok so I finished with those MK808 720p kernels.
I've made 2 different ones.

The first kernel can reach 1608MHz
kernel_720p_mk808_1608mhz.zip


The second is limited to 1416MHz
kernel_720p_mk808_1416mhz.zip


Other than the 720p resolution they should be the same as the 1080p kernels I previously posted.

Edit: Ran Antutu on both kernels.
The 720p 1416MHz scored 9100.
The 720p 1608MHz scored 9545(I lowered to 1512MHz with setcpu otherwise I crash)

Heyy those who have used this 1080p...

i just recieved my mk808 and downloading finless rom... :D :D :D :D :D

is this kernal stable??

i need : wifi... (i have a router near to my TV so non stable/weak will do)

usb sound card support...

and other basic stuff

does thios kernal support this?

btw i havent tried your kernal yet but deadhp1 thanx for ur support/dev.. looking forward to more of it... :geek: :geek:
and if possible please keep a changelog of whats working and whats not so that noobs like me get some idea :P

Hi Deadhp1,

Thanks a lot for the kernels, its great work :)
I have a started a thread in the development section for support of "usbtouchscreen" kernel module, but actually if you could build a 1080p 1416Mhz kernel that includes this support, it would be even greater :)

Let me know if it seems feasible.

All the best,
Tom.

Thanks for the instructions.

It should probably be clarified that after you uncheck everything but the kernel, "Flash as you would using the RKflash tool" only includes clicking "Flash ROM" and NOT clicking "Erase NAND (IDB)" as the Finless ROM read me indicates.

I did this and my unit would no longer power up. So I had to reflash both the ROM and kernel again, then reinstall all my apps/settings again. Later, I reflashed another new kernel (skipping the NAND erase) and everything works great with no need to reinstall anything.

I'm adding usbtouchscreen into the next kernel.
I'm also adding TUN support.


I'm also still working on building that ICS kernel.

Ok I built a new kernel.
This one includes support for usbtouchscreen, cifs, and tun.
I can't really test any of those at the moment.
It runs at 1080p.
I've also changed the kernel boot logo.
No other changes that I can think of.

2dark4u apparently is trying to compile or have compiled a kernel for the UG802 with some nice features! (Not Available yet)
and made this post few days ago:

4. CPU, GPU, RAM stable overclocked to CPU@1416, GPU@400, RAM@1333.

Sounds interesting, but I only got a MK808 and i heard UG802 has slighlty different hw, like WiFi .. not sure what else.

Maybe some ideas to inspire you?

P.S. I'm running your kernel 720p @ 1512mhz (1608mhz too unstable), and working great so far.. gonna do some bench tests.

Deadhp1,

I just checked your new kernel :)
First I was surprised by the fact that the kernel was only 3,x Mb instead of the previous 6,x Mb, how did you do this ?
So to check that i wasn't missing anything i went to system/lib/modules and didn't see a .ko file for usbtouchscreen, i was afraid ...
But nevertheless i plugged the touchscreen to see the result and ... TADA !! :D
It works :D

I have still to do some tuning with the .idc file cause the calibration is awful but at least it is recognized and it gets the event, show me the pointer location and so on :)

Thanks again so very much,
Tom.
P.S. : once i get it properly configured, I well all let you know about the set-up in a seperate thread ;)

After doing some benchmarks with 720p 1608mhz kernel @1512mhz.
I can definatly say that its much faster and smoother now, loading apps and using the interface.

Doing some AnTuTu benchmarks ( AnTuTu 2.9.3 ), shows that RAM and CPU has improved compared to the stock kernel supplied in Finless 1.5A rom. (Max 1416mhz) Although in the 3D department, I noticed that its not as fast.

I get constant 60 FPS during the scene where the knights are swinging swords on stock kernel.
But with deadhp1's kernel, I get around 45-55 fps, give or take.

Any thoughts on this? was the GPU OC'd?

2dark4u's kernel should be very good. I'm looking forward to it.

As for my kernel:
I've tried overclocking the GPU and did not notice much of a difference.
I haven't overclocked the ram.
I already have bt usb stuff enabled in the kernel.(the system is a different story though)
I've also enable pegasus/asix usb ethernet.
Xbox controller enabled.
tun, md4 and cifs enabled.
The latest 1080p kernel I just made has NTFS write/debug support.


Just let me know what you would like enabled in the kernel. If it supports it I can enable it.
I generally don't like to enable things if they can't be tested.

Would it be too much to ask, and try doing some OC'in with the GPU & RAM? Noticed that 3D not as fast compared to stock firmware.
Looking at numerous mali gpu based roms out there, seems like 400mhz seems like to be a magic number :|

I had tested changing the gpu clock last night, but I didn't see a difference in antutu(when the knights are swinging)
I must not be doing it right, so it might take a couple of days to work that out.

Cool, also not sure if this will help.
But i was reading up some specs for the mali 400 GPU over here:
http://www.arm.com/products/multimedia/ ... ifications

Seems like there is 2 frequencies for the GPU or two available speeds/version?
240MHz & 395MHz.

Not sure if this helps, but im excited that you are gonna try and work some GPU tweaks. :)
Thanks!

deadhp1, can you please add support for Realtek RTL8192SU usb wifi?

thank you,
