Unbrick or fix NAND on the MK808

[TheDuder5123]

Just an ideea ...
Can you take a look at miniUSB connectors (soldered to PCB) ?[ATTACH=CONFIG]1303[/ATTACH]

Seems good, doesn't it?

It is rare MK808 breaks off a usb port as they are mini-USB not micro.

I still think your having some kind of USB issue with your PC! We have seen this before.
If you know how to go into your BIOS make sure USB is not set to "high speed" and is in compatibility mode. If that does not work then, you may have to try another PC.

Dear Friend Bob,
You have here, in Lisboa, Portugal, one more friend satisfied and happy.
My MK808 is yet naked but alive again.
The more dificult was to find the space betwen the 8 an 9 pins.
Ok its done
Thank you very much.

Things gone wrong again.
sudenly stoped booting.
When I try to use your tool to Erase NAND IDB I get always "ERROR download boot failled".
Why?
I noticed that there is a ? in the RK30 device driver in device manager.

Hi,

same situation is for me.

I got new mk808 yesterday, and I have it worked few hours, after shutdown I was not able to start it again. I try to flash with custom ROM but can not succeed in recognizing drivers in Windows.
Only solution that works for finding drivers is this NAND reset. Every time I was getting the same error "Download boot failed". Only once, after waiting some hours I succeed to start erase process but unfortuantely it not finished completely.

I left it that way over night. This morning I try to plug unit and I see on screen broken android robot image with exclamation mark. After power off again I can not start device. Does anyone have situation something like this?

I think that there is something with waiting few hours before trying again.
And is it possible to get out from Rom mask mode once unit get in? Or is it always in that mode until successful NAND erase?

If can help, in attachment is log from Rom flash tool with all my tryouts.

Thanks,
I hope we all solve our problems with this device

[dirtytuga]

yet and allways the dam "Download boot failed".
I give up with this one and yesterday bought another cheap (shit) 808 from China.
Will arrive in ...30 days? LOL

Hello everyone, and Marry Christmas...


I have a similar situation than other guys.
I bought the MK808 on aliexpress.com, and I received the product on Dec 18th. It had worked very well for 2 days (streaming from my PC through Serviio DLNA Server and using MX Player as videoplayer, all was fine).
Due the product doesn't have a native application to Restart/Shutdown, I downloaded an application called "Shutdown" (https://play.google.com/store/apps/d...bicoo.shutdown) from PlayStore, and I made some test with application a couple of times. All appeared to be fine. However, I decided to disconnect the power supply due to a severe thunderstorm.


So, each night of these 2 days, I had needed to disconnect the Power Supply that I received into the box (5v 1.0A). But the next day, the MiniPC didn't startup. Also, the Blue led light continued turned off. The heatsink took a little hot but nothing happened. I verified trough my Router that the MK808 doesn't answered any ping test.


I used these thread to try to revive the MK808, using metal pin between pin 8 and 9, but without good luck. I recevied the message "Found RKAndroid MaskRom Rock Usb" but I haven't been able to erase NAND.


Can anyone try to help me?


Thanks you in advance and I hope all of you'll have a great 2k13.

Ok,here is my MK808 story:


I get my MK808 on the 21.12 (In4dealz) . After installing the charger the blue light turns on but the HDMI was dead.I use different HDMI cables and two different TV´S.
At this point i try to install the Finless 1.5a Rom.Everything works perfect now.
After using the stick the hole day i shutdown the stick (charger off)

The next my stick was totally dead.
No blue light and my PC does not recognize the stick (only in Mask mode!)

Here are my LOG´s

You are bricked! Use reset button and try to flash the ROM again.
