Hi there folks i need some help for a crippling situation. i wanted to modify some stuff on my iphone so i attempted a jailbreak but i was told to install a file called iousbfamily315.4 and it asked me to restart my comp so i did. but when my computer came back on the usb devises were working for about 10 seconds and then they all turned off. and every time i start my computer they dont work. it works before it boots into mac os though because i have to hold down alt to boot into macos as i have bootcamp on my mac. so at the mo i can only use my computer in windows mode. Soooo i am new to all of this modding stuff and i have no idea how to reset my usb drive or install firmware over it to get things working again and im struggling to find any answers online. if any one can help me i would be most appreciative. im sure you can understand using a comp without a keyboard and mouse can really suck!
