hey I was trying to mod my friends slim psp with CFW 3.60, like I did mines, in mines everything came out ok when I try doing his it wasn't working at first then saw that he had updated to version 3.71 so the installation of the CFW 3.60 wouldn't work so I tried this step Press L+R+triangle to uninstall M33 and go back to original 3.60. Note: this can't unbrick a psp slim, it will just remove M33 ipl. There is currently no unbricker for the psp slim, but we plan on doing one in the future. After uninstallation, psp will be shutdown automatically. after I did this and put the slim psp battery only get a black screen the green light is on but it doesn't read the memory and the screen is black and when u try a hard reset it doesn't do anything is just like frozen like that so guessing is brick is there anything I could do to fix it or atleast get it back to its regular FW 3.71????
