I havent a camera right now but the pin/connector (I dont know how to say it in english) its dark.Could you show a picture of the DAT0
No. The computer doesnt recognise the 3DS. It says: "Connect the unit X"... But following the steps in an spanish forum,i watched a little thing... The "cable" (another time,my english its very bad) with "L" shape its broken. If i send the console to a speciallist,he can join them and recover the unit flashing via DAT1?Check with a multimeter to see if theres contact from the board (Dat0) to your pin or the end of your wire.
I dumped my nand yesterday with a diff error.
As long as you have 3 of the same nands with all same md5s/file sizes, you should be ok.
