Cant unlock Huawei ETS3125


Hello, I need some help to unlock Huawei ETS3125i, I’ve made the cable RJ45 to USB, and I think its ok…
But when I start the Vodafone infineon module, the lights of the Furious box port shows activity like ok (yellow and green) but the software shows this:
Press END button shortly !
Error … !
Time needed

Is this a cable problem? does anyone has a more clear schematics about this cable? Any help you can provide it would be great!

Thanks in advance.
