ya, someone else said i needed the memory stick reader-so your 100% if i use the mem card reader i will be able to turn on my psp? I didnt know that trying to install the 3.71 m33-2 could brick the psp- but i guess if you dont have the 371.PBP it does- also my bro's psp was at 2.82 sony firmware when i tried it on his, can that be fixed the same way (by using a memstick reader?)
