None of them, they don't work on 3.90M33.
For 3.90, you'll need to use the Universal Unbricker. Check it out in the FAQ guides. :D

I need a Porsche 911 Gt3.

If you read the guide it will explain it all - Whatever you decide you will need a pandora, and more than likely DC7.

Hey!
Umm..
I had a psp with custom FW and was successfully able to update it to 5.00 M33-3!
Now I've got another one with original FW 3.93 and want to change it to custom FW!
Don't know how! Can someone help me?:O
