R-sim 10 fail iphone 5c sprint
 

i just got an R-sim 10 which im trying to use with an iphone 5c from sprint and my current carrier cricket. when i first installed the R-sim with my cricket sim i got the usual menu's which i chose AT&T at the first menu because thats who owns cricket now than the I5c, 4G sim card(TMSI mode US) and than it told me to reboot. now it didnt do anything and i still get a sim activation error. i cannot get the phone to load the R-sim menu to change settings like it did originally. how do i get back to that menu?!?!?!
