Dop-IOS MOD is a modification of the application Dop-IOS that allows you to choose which IOS you would like to use to install other IOSs (with the trucha bug if you like), channels, and system menus. It also allows you to install a patched IOS 36 to use to install fakesigned content if you don't have any other usable IOSs like Trucha Bug Restorer does.
Changelog
v9.0
Fixed a small bug causing the improper version of an IOS to be displayed after it was updated
Added automatic region detection
Added code from Trucha Bug Restorer so you can go through a short process to install an IOS (IOS 36) that accepts fakesigning if you need one
