I have a Ta-082 PSP that I downgraded to 1.5. I then upgraded it to 3.52 M-33, then to 3.52 M33-4.
Now, I can't seem to upgrade it to 3.8. I have everything correct, but when I upgrade, it says cannot open file..then some weird code. I formatted my flash-1, and then I tried it again...but then it says the same thing. What's wrong? I read at some other forum that i had to patch my key 5? What the heck is that? Thanks.
