MK808B (RK903) KitKat 4.4.2 ROM

[Junia]

I have attached the dmesg from the 4pda ROM as requested. I knew the ROM/Kernel from that post wouldn't work but I downloaded all known kitkat ROM's for the device in the hopes I could get one that worked. I should also mention that after flashing the 4pda ROM, I can flash the system.img from your ROM and it will boot and work but no WiFi. If I then flash your kernel I get the 2 penguins again.

I just checked the purchase date on Geekbuying and it was 2013 & it is RK903, not a clone or variant. Thanks for your help

Junia .... Looks like a Realtek chip. If you open up the stick it is suppose to look like this...

[Junia]

Thanks for your response, I did open the device and have confirmed it is original MK808B, It was purchased from Geekbuying back in 2013. The kernel used in that dmesg is from the 4pda rom for realtek devices. At this time, that rom is the only kitkat that will boot on my device, although wifi or bluetooth wont turn on as my device is rk903.

Hello, I was looking into the issue again today when I noticed a slight variation from the pic that RWSTARKE posted.

As you can see from the picture I attached, I do have a rk903 chip and my board is the same but there is a difference in the numbers shown.

Mine shows rk903, tod1002, 1305
Yours shows rk903, tod2002, 1310

Perhaps this is the issue?

The pic that linked was from another post in the forum. Here is my MK808B from Geekbuying. I have not yet tried to install this ROM/Kernel.
(You can see I added a wire to connect to an external antenna.)

Mine also has 2 penguins, the RK903 chip reads

I've built a new KitKat ROM from scratch. Link's in the OP.

I hope that it will work an all MK808B/RK903 devices. Also, make sure that you run EraseFlash before the upgrade.

Unfortunately the new rom is still giving me 2 penguins. I have flashed it fully on 2 different machines to verify. I think it is likely a kernel problem as I get 2 penguins even if I don't flash the system image (to restore 4.2.2 I flash everything but system so I can quickly use CWM to restore a backup).

Please let me know if there's any other information I can provide that might help.

Thanks for all your hard work. I will test tonight when I get home and will report my results.

I wonder why some of the MK808B sticks like mine have this printing on the circuit board and others do not ...."MK808B_V1.0_2012.10.24"

[Junia]

Unfortunately the ROM freezes during the boot animation. I am definitely getting much farther then before as I get passed the 2 penguins without issue. I will play around over the next few days to see if I can get it booted.

BalintBanyasz - Did you change anything in the Kernel with this new ROM?

In mine the 720p is working fine my hardware photos:

Could you also make your new rom with 720p kernel?

[Junia]

Looks like we have different RAM chips.

[caam14]

That should not be a problem.
