I'm considering getting a PS3 Slim for CFW but I don't have a home network (needless to say, bans aren't a concern). If I buy a used system that already has HEN, could I simply switch to CFW if I have a flash drive prepared? Maybe HEN's all I need?Or does HEN require an online connection to re-initiate the exploit at each boot? And assume the HDD is required to boot (being used, I won't trust it for my saves. Maybe upgrade it though), but can I play games directly off of a flash drive with CFW / Hen?
