I'm fairly new to PS3 modding and all the custom FW stuff, so If I'm asking a stupid question, please help me out with it, thank you 
I've recently bought my first 500Gb PS3 with HEN and WebmanMod already installed on it.
My friend gave me an original copy of Destiny and I love to play with it, but when I start the game and want to log in with my PSN account, I cannot, because the guy who sold the console to me, logged in with his account (master account for PKGi?). Sadly, the seller is not helpful at all and he doesn't want to add my account to his and says that creating a new user is forbidden too, because it can break the modding.
My question is, can I change the original HEN HDD to another and install back the original PS3 firmware to play online and when I want to play offline, put back the original HEN HDD and continue to use it with the mod?
Or is there any other way to play online without risking a ban?
I hope my question was clear
