[hassenman]

i need to flash a samsung x100 , i ve got a data cable , and i need the falsh cable , i know that normally a flash cable should have an external voltage source , but the shematics found here  --> http://pinouts.ru/data/samsung_x100cable_pinout.shtml

don't show any external source (uless it uses the battery voltage)  and  the capacitance values aren't clear .
can anyone help ?
