To recap Idid the JB once but as I had special deals I've done a reset before I remove theses ones. The probleme is that now I can't remake the JB, even if do the exactly same thing as before, after connecting to kindlefere.com/jb, agree, do stage 1, went back, do stage 2 and I got the message JB starting then the message where I have to search ;fc-cache but when I press return: nothing happen, even if I search for it more times, I think it's like if it was missing from my PW... the first time (before the reset) it worked perfectly nut now it's different... :/
If you can help me I'll be thankful
PS;I didn't uderstood well waht you were saying, my english vocabulary is a bit light
