if you have a clone you can update it with 2.57 fixed firmware , or if its a genuine you can update it with V4 and the keys auto roll for you so you dont have to manual input them each time
You can find the files here , thanks to Eamo http://eko.4shared.com/ You also need the gt rom loader to transfer the files to your SV
thanks for that truth is i just bought it from a friend of a friend so dont know what ive got only got the box
Count the vents on the top , 7x25 is Genuine , 7x18 is a clone , also to to Menu> System Information and see what version you have installed on the box. You also need a Null mobem cable ( 9 pin female to 9 pin female ) to transfer the files
