If you only read more.... hehehe. anyways, they say that holding 2 and 5 will help, phone not powering doest not mean it cannot be detected, thats why most softwares (phonexs, SEUS etc) tells you to press and hold "c" before inserting/plugging in the usb cable. hope this helps.
P.s:
i still don't have that file i'm asking above. :D
PEACE!
