Can you tell us which PS3Key you have, Al_Jourgensen? There is a version that you cannot upgrade, as well as a Atmel and Silabs-based version. If you go to PS3Key's website, you can login and access the downloads and hexes necessary to use your PS3KEY to enter Service mode. If it's one of the non-upgradeable PS3Keys, I'm afraid you will be out of luck on using it to downgrade. In any case, you can use the tutorials in the Game Backup Forum to allow homebrew and backup managers on the current 3.55 firmware, without a need for a dongle. You can find it here: http://psx-scene.com/forums/f187/%5B...noobs-d-76406/

Why don't these new users ever check their companies homepage before assuming that we have the files for their device? Anyway, stock2255 is correct, goto ps3key's website and see if they have the files for the device, if not, use a 3.55 CFW or find another device you can downgrade with (iPod/iPhone, sansa player, ti-89 calculator, HTC phone, etc).
