it's exactly the same problem as with my T9 +, see my subject;)

In your case, I am 99.9% sure that with the PicKit3 you bring back to life your card!

1: extract the HEX file from a functioning card
2: the reinjected into the card that does not work (FW 0X00)

Ps : the PicKit3, the cost is ~_ 25USD
