Sorry try what?
I'm still in the act of installing the modification
After I make the change I can tell you if it's a scam or not
But I hope it is not a scam and not to have thrown my money

And I'll be very happy if a modification works.
But if it's a scam I'll tell you right away because there will not be any other scammed users.
I also paid, but I only got useless files, and nothing works ... did you install the firmware? to me after I paid, and he sent me these useless files .... he ran away! for me it was just a scam!
