No european psps came with anything less than v1.5.Sponsored Links
I tried the technique explained in the post above, (first one), and it did not work, my PSP got pissed off when I took out the disc and rebooted after I put the 1.5 in.
A crying shame tho..
@arvidlu: Did you try sticking the UMD detect switch down when you did this? (see post 3 - posted by ps3news)
I'm just asking because i'm interested - i have a 1.5 JAP, am not likely to upgrade, but keeping my ears to the ground anyways!
No, I didn't.. it seems kinda dangerous, plus if the technique didn't involve the detect switch then it probably doesn't work anyways.
