Can anyone help me how to downgrade my metallic blue PSP slim model 2001 version 4.05 to play ISO files? It didn't start as a version 4.05, it got upgrade while playing NFS Undercover. I don't know what its starting version is, but it came from Madden PSP Pack.

I have been trying to look for a solution in google for two months but I still don't know how to make my PSP play ISO files. Please help me

Yup yup, its true, if the PSP comes with 4.05 it is a fact that it comes with the new T088-v3 so we have to wait, I got 3 friends with that problem, so they have to wait until someone gets a way to do so.

PSP (+[__]%): 2.80 < 1.50 > 3.40OE-A > 3.71M33-4 > 3.80m33-5 > 3.90m33-3 > 4.01m33-2 + 8gb MSPD
PS3 HD 60GB: 1.33 > 1.90 > 2.01 > 2.17 - NO OS
Nintendo DS [+[__]%]: EZ Flash 5 Plus + 1GB MicroSD + EZFlash 3in1
Nintendo Wii: 3.2U + 1GB SD Card + WiiKey 1.9s

lol i remember how long it took to crack the original psp...it took a good 5-6 months.

hopefully itll go faster this time around, but dont bet on it.

Lets just hope dark_alex is working hard out there!

He said it DID NOT start as v4.05, it could be a workable motherboard.

First of all you have to create a Pandora Battery and a Magic Memory Stick.
