Hi,

I bought sync 3 emmc programmer with fixture, but fixture not good with my board (my emmc board …8740D, this fixture good for 8470A).
So I have emmc reader and software, but I dont have wiring diagram / connection manual.
My sync 3 went black screen during update navigation map.

So I have new emmc board but I would like to repair old emmc board, so I need to read emmc and copy to old emmc board.

My emmc board number: M3J4118740D
My sandisk flash memory: SDIN8DE4-64G

Thanks,
Laszlo

The first rule of Cyanlabs is: you do not talk about Emmc. The second rule of Cyanlabs is: you DO NOT talk about Emmc!

This used to be true, not so much anymore, that said I won’t go in to specifics personally but if anyone else wants to feel free (keeping it legal and without links to intellectual property)
