Unbrick or fix NAND on the MK808

[l0ur3nz0]

So, no hope for all of us with a semi-dead MK808?

To make this worse, geekbuying is not replying to my e-mails.

Re: NEW - Unbrick or fix NAND on the MK808

If it is the RK808, but I'm afraid to put the omegamoon Kernel.
While so easily solved ...
Thanks for your help.

Omegamoon kernel is better than stock one for me, but I repect you if don't want to flash a kernel, I have a mk808b so if I use custom kernels, I lose BT and wifi, i can live without BT but I need wifi, so i am condemned to the stock one by the moment I hope we get our wifi in mk808b working soon, that will be a incredible advance.

If your device is mk808 i suggest you install omegamoon kernel, he did something in kernel what makes this device boot without hdmi connection assuming that it is there, Some TVs don't give a connected signal to the tv stick so it fails to boot properly. unfortunately the kernel only work 100% with mk808, other devices like mk808b, mk802III, etc dont have suport for wifi and BT yet.

I found that the problem lies in the HDMI from my TV.
If anyone is interested, see the link below:

Need help with serial connection

Hi again,

I finally got my USB to RS232 converter and I connected it to designated pins on board as stated in blog:

http://www.omegamoon.com/blog/index.php?m=01&y=13&d=13&entry=entry130113-161359

But when I start putty and powered device, all I see in putty is:

DDR Version 1.00 20120529
In
Unkown Device
ERR

Is this mean that my mk808 has dead memory, or I missing something else? Is there anything else that I can do with this serial connection?

Thanks and best regards

Thanks for your answer, but my PSU is 2A and the HDMI cable and the TV are the same as when it worked.

Edit: My problem has been resolved by disconnecting the USB Hub. Everything returns to normal operation.
Thanks for your help.

I told you yours was still fine...

[ALSINJAN]

Your MK808 seems to be fine. Just try it with other PSU (2A) and wiggle the HDMI cable. You can also try other TVs. If this doesn't work, go back to the original ROM or other custom ROM.

My RK808 (purchased in DX.com) has worked well with Fitness 1.6 ROM until yesterday.
I turned it off normally and on again: black screen. Blue LED on. I flashed back to Rom Fitness 1.6 (zero errors) but without result: black screen.
What do you suggest I use?:
- Flashing back to original ROM.
- Flashing back to stock ROM.
- Use the method of pins 8 & 9.

Help me.

Try to change the USB cable, the USB port, even the PC ...Use always one "true" USB port (located on MB, not in front of PC case). Good luck !

HI darkenpt,

Be more specific.
Show all the steps you did to put the stick in mask mode, and the error step.

I I shorted the pins 8 & 9 of the NAND chip, connected USB cable to the OTG USB port and nothing.. MY PC does not recognise the MK808. I have installed the drivers before I briked de Mk808 so I think that is not the problem.

Thanks

Help please

Hi all,

Fist of all I would like to tank you for the participation on this great forum, I learnt a lot with you guys

Now, I am sorry if anyone already make this question but... unfortunately in the process of building a new home for my MK808 (make a new case with power supply and USB hub inside) I think that probably I briked it :|

I have tried to put the MK808 in MASK ROM mode but with no luck, what else can I try? it helps if I solder some wires to the "JTAG" interface of the MK808 and see if I get something?

like this:

or there are other way?

Thanks in advance

At this time, my stick is flying over the seas to Finless's home...
I received from China and now is flying to USA.
It's kind of world tour....LOL
