i bought a a cable & extender on ebay .
http://www.ebay.com/itm/FFC-FPC-30-pin-0...1985309073
this worked. i also bought just a ffc cable on digikey,
http://www.digikey.cz/product-detail/en/...ND/4573405
and that works.
the one from ebay also has AWM 20264 80C 60V VW-1 on ribbon so i do not think that your piece with that marking means all pieces with that marking do not work. i'd suggest to unhook everything, hook back up, perhaps burn a new sd card. just go from start and try again.
