How do I decrypt IMG3 files please? --Jaggions 07:40, 25 October 2012 (MDT)

Firmware Keys#Notes should give you some starting notes. The command line is (for img3):

xpwntool "{IN}" "{OUT}" -k{KEY} -iv{IV}

Then using dd or your favorite hex editor (I prefer HxD for Windows), strip the first 0x40(?) (64) bytes (the img3 header) of the file. --5urd 09:38, 25 October 2012 (MDT)
