Hacking Homebrew Did I just half-brick this Slim?

[HeatMan Advance]

Ok, I'm a noob at using PSP ISOs.

I simply made the iso folder, put MGSA in it, installed CFM 3.71 M33-3 and UMD Emulator V0.8C.

I thought the ISO would work this way based on al the videos I watched, tutorials I watched and question I asked here weeks ago.

Regular games on UMD still work fine, but I can't get the ISO on the card to even show up when I look on the stick for it from the PSP. I can't get rid of v. 3.51.

I'll worry about putting games on it some other time. I just want to get this firmware off.

It's really simple.

1) First backup any data that you've added onto mem stick
2) Disconnect the USB and then in the PSP go and format the mem stick
3) All the needed folders will be there
