Title Unsigned - Downgrade from OS 2.55
Description This program allows you to downgrade your calculator from OS 2.55. If you bought your calculator after August 2011, most likely your boot code (1.03) will not allow you to downgrade. This program applies a patch that will let you install any operating system you like, including 2.43. This program also allows you to put you name on the about screen.

This is an awesome program. I can now put my own apps on my calc, without having to deal with all of that stupid "validation" mess. One thing that I don't like, is the fact that I can't send an OS to my friends calc, it always give me the validation error. :(

Overall I give this program a 9.999999999999999999999999999/10
