[ps3nemesis]

1.USE AT YOUR OWN RISK! the tutorial is somewhat long so beware.
2. this method only works on ps3 models made before 17th feb'09

please also if your ps3 came with firmware higher than 3.21 ie....3.25 / 3.41 do not go lower that origonal firmware.

check on the bottom of your ps3 for manufacture date some consoles may have a dat code ie...7c the key to the code are as follows..

7A = First quarter of 2007

7B = Second quarter of 2007

7C = Third quarter of 2007

7D = Fourth quarter of 2007

8A = First quarter of 2008

8B = Second quarter of 2008

8C = Third quarter of 2008

8D = Fourth quarter of 2008................ and so one 2010 is for example is 0A=1st quarter 2010


all above was figured out by me

3.Getting started:
4.*2 USB Flashdrives, 4 GB or more* <<<<< That means NO (Reapeat) NO 2GB Flashdrives!
5.*2 PS3 Controllers Via USB*
6.*A Computer, you obviously have one -.-*
7.*A disk that will run in your PS3, BUT NO DvD's!, CD's Work best, or EARLY PS3 Games (EARLY!!!) *

11.
12.Your second USB will contain your desired frimware,
13.Whether that friware is 3.55, or 3.56, 3.66,
14.Just put it on the USB in the PS3 UPDATE folder
15.
16.-Now go to your PS3, start the restore mode menu.
17.----**Okay, all idiots that don't follow from here on WILL brick their console, seriously.**------------
18.
19.----*Plug in both controllers, if your second controller does not turn on, you are okay,
20.if it does, you need to put it back into restore.---------
21.

[AshWood]

Wasn't this already posted in the member news section

edit
whats with all the asterisks ?

[cawthorne]

Yo nice post. I will be doing this. (I didn't upgrade by accident, I'm not an idiot, I just have 2 consoles and decided to upgrade one of them).

It needs to be cleaned up a bit to make this easier to follow, also when you spam o, what would the button be for a Japanese console? That's what I have and I think the x and o buttons have different functions to the norm, but I'm not 100% how differently they're orientated exactly.

At this point, just gonna wait for someone trustworthy to confirm this mess... Cause it's really messed up.

[patmorita]

By holding eject for 15 s dont you enter to the dreaded "fan test" in the old models? you know, the one feature that ylod your console...

[really_wacky]

Why are there so many steps missing? Allso its hard to believe, this would work. How do you even figure out stuff like this :S

[albionsblade]

Why are there so many steps missing?

More profit???

[MrX4000]

Wait a minute ........ What ???

[really_wacky]

No i said it wrong what i meant was:

Why are there numbers from 3 to 88, and are there empty ones in between? Numbering the steps would make mutch more sense. Then you could say: I ****ed up at ex step 5.
