hi
mate i m also using powerflasher and may be i may be of help to you
first there has to be some usb cable delivered with it,connect the master with pc and then use another usb cable join the slave to the master but this methode is unecessary for you at the moment they are mostly joint together when two people want to work with it or may be you are working with master on another pc and someone can use the slave on other pc
you must intall the set up suit for powerflasher on your pc and all the drivers has to be installed before you can start using them
on the issue of unlocking manual there is a web site with german language i dont know if you can understand german if yes then i will link you |
