    There are two options for you:

    Get a Phat or SLIM PS3 at any Pawn stores and it won't hurt to ask them if you can test it so you can checked the firmware to see if it is 3.41 or 3.55. Thats what I did and I grab one that had 3.41 in it. :D

    Other option: Buy a expensive E3 Flasher that can cost 70 to 100 dollars. It is not good for a beginner, thought. I recommend to get one at the pawn store instead.. Its cheaper and hassle free.

    You could use a progskeet, E3 is just usually the first recommended because it's the most straightforward, least soldering option.

    Yours has NOR flash. http://www.psdevwiki.com/ps3/SKU_Models
    I'm actually not sure if E3 even comes with a NOR model, so Progskeet might be the better option in your case.

    I never got my progskeet to work on nand or nor, i got 2 1.21 if i shoud recomand any flasher, it would be littlebalup's teensy adapter,
    http://www.psx-place.com/forum/down...eensy-2-0-ps3-1728.html?highlight=Littlebalup
    its chesper than e3flasher.
    Ok it harder, but its more funn. It aint that hard to solder, just be sure you practice before starting with the adapter.
    Playstationhax.it have also a adapter, but it is only for nand, not nor ;)

    Never solder before i made that Playstationhax.it adapter, it is easy if you take it slow and use flux ;)

    Teensy++ 2.0 is the best choice, and it's also very cheap.

    CECH-E01 has NAND flash, very hard to downgrade. You need to solder alot of wires.
    Best is to get a NOR console and use E3 flasher to downgrade, no soldering needed when you use the clip.
