In my mind, Boba buried Jango's armor like in the Boba Fett series. (those relatively new books, taking place during the Clone Wars) And later on he found his own armor, which had been Jango's mentor's armor, Jaster Mereel. I am confident that most of the "armor damages" (including the dent) came when Jaster used the armor when he lead the mandalorians. (Read Jango Fett: Open Seasons).
I tend to never really trust EU at all though, why? BECAUSE IT'S NOT REAL! Unless George Lucas says anything, it says so on starwars.com or is in a movie, then it's notihng more than an authors imagination and should not be taken too seriously.
