I know i'm a nwb. I know you hate it when we don't google it, but i did. yall seem to be the most knowledgeable source on the web so here i am and here is my story. i've had a 3.30 psp but recently swapped with a friend for his 2.00 fw normal motherboard PSP. i know about the MPHdowngrader but everytime i try to unzip it my virus protection kicks in and says the .TIF is a virus (more specifically Trojan PSP.Brick). i wnat to know what fw i should update to, what method of downgrading and where to find the downgrader and tutorial for it so i don't brick my PSP. Thanks for understanding and please help me however you can and be warned that once the downgrader works i will probably be asking for homebrew, emulator, and iso help (if those topics are allowed on these forums).
