How to downgrade the PS3 firmware

post #1 of 5
Thread Starter 
Is there any way to downgrade the firmware without soldering? I ran the MinVerChk and says I can run 1.90, goal is just to get it to 3.55. Have no clue how to go about this. Trying to sell my PS3 and the person that is looking at it wants a system with 3.55. Thanks!

You will need the E3 Flasher to downgrade your PS3. There are also downgrade services on Ebay that can downgrade for you, but be careful on choosing one.

A Nand/Nor flasher is the only way. There are several, but the E3 Flasher as awdrifter mentioned, is probably your best bet. Everything you will need is going to cost at least $90. You will need the E3 Flasher itself, a downgrade dongle, a 2GB or less Micro SD card, and a flash drive. Both the Micro SD and Flash Drive have to be formatted in FAT 32. Soldering is not required with the use of the NOR Clip that comes with current E3 Flasher's, since it clips directly to the Nor chip, but they can be touchy, however, as they require constant, even pressure.

Here is a page showing the numerous downgrade dongles that are available. Maybe awdrifter can chime in here, I personally do not know which of these would be the best choice. I have a psp that I can use to get into service mode, so I wouldn't need one of these dongles.

Here is the E3 Flasher.

Honestly, you would be better off finding a new buyer than going through all this.

Those downgrade dongles came out before 3.56+ OFW. After 3.55, a hardware flasher is required for downgrading.

Thanks! Yeah I wasn't planning on going through all the hassle but was trying to pass info on to the buyer. I'll be looking for another buyer, after all that he decided he only wanted one of the games and the console.
