Help - Need to flash MK808 again

[JorgeO]

Hello,

My MK808, Finless 1.7c ROM is half OK, half broken. It works but in a limited way.

I would like to erase NAND, flash it again, but ROM flash tool will not find it no matter what (using the paper clip reset).

Thanks for your help,

What OS are you running? Not Windows 8.1 by any Chance?

No, Win 7 Home Premium, the same OS and same PC where I flashed Finless 1.7C some months ago. It all started when MX player was updated.
Now I cannot delete anything, factory reset doesn't, etc but it's not dead.

Check your pc device Manager. Does the stick show up there? If not, are you using the otg port?

Yes, it´s in device manager as Rockusbdevice and in devices and printers as unpecified device. But both flashing tools (from Finless 1.7C) cannot find it.
