Ok here is my problem. I found out about this whole custom firmware thing 2 days ago, so I took my 1.5 and installed Dark Alexs 3.02OE-A firmware and everything went fine, then I upgraded to 3.02OE-B and everything was fine. The I after having my Suikoden PSX iso fail to open I started looking for a problem and found that upgrading to 3.03OE-A and then 3.03OE-B might solve my problem.

I took the following steps:
1. I got the 3.03OE-A files and used the oeupdmaker with 1.5 and 3.03 firmwares to create the data.dxar file.
2. I then put the 303oeflasher and 303oeflasher% folder with the data.dxar file in the 303oeflasher folder into my psp/game/ folder (which is set to 1.5 homebrew through the recovery menu).
3. I go to use the update and it starts installing the 1.5 part and then the screen just went blank and the orange led on the left of my psp which i think is for network stuff would just bink rapidly for 2 seconds then turn off for 3 seconds and then would repeat this.

I thought it was installing so i left it for an hour and came back to find it still doing this, so i shut it off and turn it back on and it would just come to a black screen with the orange led still blinking in the same fashion.

I then attempted to use the flasher for recovery that came with 3.02OE-A to try to convert back to 1.5 using the recovery menu only to find it bring me right back to a black screen with that blinking orange led when I click to use the file.

I have no idea what to do here, all I can do with my psp now is access the USB through the recovery menu.

How can I revert back to 1.5 and install 3.03OE-A without this happening again, please help I have been all over google all morning trying to fix this thing, any help would be greatly appreciated.
