Oh,I just searched and read DIY SCHOOL (unlocking locked Hearing Aids).now It's easy for me entering code in target but here is no information about IPFG.
Good question. I changed the DIY School Hearing Aids PDF file named (Unlocking Locked Hearing Aids) to add a Phonak iPFG section. When you run the iPFG install, it installs with an Installation Key (just like Phonak Target). So I am assuming that you can change that Installation Key just like Phonak Target. Though, I have not heard much about (very, very, old) unlock codes for Phonak iPFG?? Maybe Phonak Versata M??
