Newb on 4.20 ofw
 

Hello all,

Im a newb on ofw 4.20 with a fat ps3 CECHE01

im thinking about buying an E3-flasher to downgrade to cfw 3.55

im not new to hacking but i am when it comes to the ps3, this is my first shot at it and im open to help. Ive done some research and the E3-flasher seems to be the best available option. I looked at the NOR/NAND compatibility list and i see my model number is a NOR although their website said slim models but i did see a youtube video with "CHRISTECH TV" and he had a phat ps3, so this is where i come to yall for help. where do i start? where is the best place to purchase the E3 flasher? do i need any other equipment? one of the E3 flasher websites said i needed ----->"You will also need a downgrade dongle such as the E3 Card Reader to perform the downgrade"
Is this really neccassary?
and my final question..after i use the E3 flasher how do i use the dual boot capabilities? do i have to remove anything or turn something off to go back and forth between firwares?
sorry for all the questions but i dont want to break my machine, im sure you all understand :)
Thanks

Yes @Kazrael21 you need a dongle in order to do the Jailbreak, the downgrade part you do it with the E3 flasher.

You need to hard disk drives. (Dual boot)

@Kazrael21

CECHE01 is not a nor model. You must have looked at the chart wrong.

Look here.

It is a nand model, so I would suggest Progskeet.

What @playerkp420 said, you're going to have to downgrade your NAND not nor and all the files/info are on the PS3devwiki. Check here.

If you are still unsure just ask.

Does Progskeet require someone to solder?

Oh, yup you're right i did read that wrong. thanks

Is there any way to downgrade my model without soldering?

Yes.

No.

I did some reading on the website and saw the solderless progskeet (minus the actual soldering of some hardware to the ps3). has anyone tried this yet? how did it work for you?

Im thinking about buying the solder less NAND clip but not sure where and i havent found any tutorial videos on youtube or google...im a newb so i like video help haha

Last I read on the 360-solderless clip was it has a fire hazard. This was last year I read that so it may be different now. Most who use the Progskeet find it better to solder.

Here's a guide and @racer0018 does it for you for fee if you aren't comfy doing it yourself. NAND & NOR PS3z.

There are solder less clips Available, Also anything you attach to your ps3 is a possible Fire hazard.
