I Live in the Dominican Republic
About a week ago I ago i bought my second psp which was used and came with 1.5. 5 days later it didnt read umd's and couldnt boot games with fastloader or umd emulator so I took the psp to the shop which is kinda of an illegal shop which they hack everything. SO he says hes going to upgrade to 1.52 to try it. Next day i go and he had it upgraded to 2.5. I got mad at him an said that that wasnt the firmware he told me and that i wasnt gonna do anything with a 2.5. He says he can downgrade any psp but is harder. He explained briefly that he opens the psp and flashes the bios and more things which personally i think is bullshit. He told to go tomorrow which is today. My guess is he's changing my psp for another one but this psp has a series of dead pixel you can identify so today im going to see what he does. I find hard to believe hes the only person in the world that can downgrade a psp form any firmware. I will post in about 8-9 hours to see what he did.
