Help Me Unlock Nec 525 With Redbox

[lacasapc]

Dear Moderators,

I Am Tired Of Trying To Unlock Any Phones With My Redbox Ii,
But Havent Had Luck, Please If You Have Any Users Manual, Tell It To Me, If Not, Please Help Me, I See Anywhere This Is The Best Box,
Allow Me Please To Enjoy Mine,

I Want To Know If I Have To Conect The Cable To The Socket Of The Box That Says "service Cable" Com 1, Or To The Other "service Cable" Box,

Besides If I Have To Press Power On Until It Is Unlocked, Cause I Havent Had Any Luck, Always, Gives Me An Error,

For Unlocking Nec, I Just See Two Cables One Rj45 An One Usb,
I Think I Have To Use The Rj45 One, But Always Error,

And Read Something And Downloaded Some Drivers, Instaled It And Ran THE nectalk Program For Unlocking, But It Gives Me An Error Usb Device Can Not Be Recognised,

So Help Me Do It With Redbox Ii.

Please
