Hi all. Thanks in advanced if anyone can help... I bought my psp about 5 months ago and i currently have 3 games (i purchased) but i want more and they are far too expensive. anyway, with one of the games i purchased, it required me to upgrade my firmware to 2.81. (when i first purchased it it was 2.71). I have been looking about downgrading my firmware to 1.50 to play iso's and if it requires a firmware of 3.x then i can use a emulator or a program called dev hook i believe. What i'd like to know is can i downgrade my psp to 1.50? when my psp was 2.71 (when first purchased), then i upgraded it to 2.81 (i know, i am an idiot!!!). so yer is it possible. also, i checked the inside of my psp (when you insert an umd) and i do see the dreaded letters/numbers of IC1003... Please can any1 help. i also do not want to brick my psp. but i know there is always a chance of that happening... thanks again... P.S. Sorry if this has already been answered. The thread can be removed if that is the case!!!
