Phone not power up, getting crazy! SEMC TOOL

Hi.
i use the SEMC TOOL USB-smart to unlock the k310i.
All i want to do is to unlock the phone and
all the time i get this message, phone not power up!
WHY?, have been trying for 3 days now.
V8.7 is the one i am using, and have selected the k510 since the
K310 is not avaiable.

What about the talking about the 3v battery, there is no 3v battery, do i need that?

Have been unlocked phones earlier, and no probs then!
I am jusing the cruiser/fighter cable.

The phone start and then it goes of and the message is coming.

I guess most of you laughing at me, but i really dont understund.
And is there anyone who now if there is a guide for the semc tool?

Please help me in some way.

Kind regards
Daniel
