the v3.1 ROM with full EJFM hack completed and CRC OK
Now don’t think that just because you can get into EJFM, you are home free. This was the homework assignment because it’s going to take a lot more hex editing to coax out the function of some of these subroutines, so the ability to make a quick hex edit will soon become an invaluable skill.
That being said – go explore EJFM and enjoy! By playing around behind the curtains a bit, you can really bootstrap your understanding of how the system works and the raw functions built-in. Peruse the file system, play around with the babyfinder shell (tap “Bookshelf” button when in EJFM) or the advanced functions (tap “Menu”). Try not to damage your device because you have enough power here to potentially cause an unrecoverable issue – ie, brick.
But most of the tools and options in here are relatively benign so take a look around and study up in preparation for our next section. Happy Hacking!
