Thanks for reply!
There's one another thing that I want to figure out: How to get a valid FI2KEY? I've tried the disassembly.pl and extract.py script,but I can only get a FI2IV,the FI2KEY segment is blank.
Is that my way incorrect? If so,please tell me the way to get correct FI2KEY and FI2IV.(in my condition,on a Ubuntu computer,and don't have a Windows environment)
My platform is IXUS 175(ixus175_elph180)
Thx.
