Hello. I must start out by saying this is a great site, and I've done some searches and found LOTS of usefull info/guides. I'm fairly certain I understand what steps I need to take, but I'm one of those guys that needs to have reassurance before he starts. Here goes: I've got a Daxter PSP Slim which has FW 3.80 on it. I plan on purchasing a Battery Tool similar to the Datel tool and using my 1gig Mem Stick to format it into a MS with CFW 3.71MM33-2. Using the batt along with the stick will allow me to install the customer firmware, correct? Is this all I need? Are there any DETAILS that I'm missing (ex. is a Sony Modded Battery better that a Datel or similar?) Option TWO: A buddy of mine has the same PSP and he's had it proffessionally modded (CFW, not hard mod). Is it batter if I use his? What are the advantages? Thanks for any and all that reply.
