Ok so, I've has a psp phat a few years a go and sold it cuz it got boring, then a year or 2 later i bought another one and now its getting boring again. The only way I could find a psp fun to use is if it had custom firmware on it. I want a PSP slim and I want custom firmware on it but I dont know the best way to go about doing this. Would it be best to buy an already modded one on ebay or buy a psp, then send it into someone on ebay so they can mod it for me or should I buy one and do it myself. Thing is, I dont know if it is possible to downgrade the firmware on a brand new psp slim and I also dont really know what to buy if I was going to do it myslef.
