DOA MK809 III TV Stick

[iosonlindoro]

Bought a MK809 III android tv stick, PCB: Netxeon_MK906_V3.0 that came Dead On Arrival.
Blue Led light when it powers up, but no signal on TV screen.

Comes with a reset button not working so I manage to enter in Mask rom mode shorting 6&7 pins on nand chip.

Installed the Rockusb driver properly, RKBatch Tool & RkAndroid Tool recognize the device in Mask ROM Mode (Dark Blue Square & Found RKAndroid MaskRom Rock Usb).

Tried to erase NAND IDB, always getting same error "Download Boot Failed".

Also when I load a firmware with RKBatch Tool and click either Restore or Upgrade lasts in same anoying error "Download Boot Failed".

Tried in 2 laptops 1 desktop, Windows 7 and Windows XP, diferent usb port&cables.

Could someone give me a hint?.

Thanks in advance

Messing around with RKAnroidTools I´ve tried two RK3188Loader(L) bin files, V1.20 and V1.24 with the same result "Erase IDB Failed" & Download Boot failed

Maybe I could try with other versions, I think there are V1.02 and V1.95 for RK3188 but I can´t find them.

Thanks.

Have you managed to do something with your stick ?
I've received also a DOA

Hi, ciprianxl
Sorry to hear that.
Nothing worked, maybe the nand chip is defective. Tried several times, always the same error. Fortunately the seller sent me a new one that works fine.

Always boot in Mask Rom.

Everytime I boot It up i got the Blue square in RKAnroidTools.
Got Erase IDB OK
But when try flash it break in next boot.
Can it only boot in maskrom by short pin 6&7?
Has it in someway self shortened it so it cant boot in other mode?
