(adsbygoogle = window.adsbygoogle || []).push({}); alright this isn't going to be for noobs to run off and try it for people who know what there doing i got all the way to taking apart my ps3 then stripped a screw :( so i need your help

alright to get things started

what you will need:
a brain (no kidding)
tools to open ps3 and pc
pc to format hard drive ( WE CAN'T USE THE PS3 FOR-MATTER)
some type of Operating System Install Disk (I recommend Windows 2000)

now what i recommend
2 ps3's one on cfw so you won't be stuck on ofw


alrighty lets get started on what to do

1. back up everything
2. take out hard drive (PS3)
3. replace PC's Hard Drive With PS3's (Yes it's possible on a desktop)
4. boot up Operating System Disk from Boot Utility
5. Install OS as you normally would
6. when it gets to formatting Delete The Whole Disk (The PS3 formatter leaves software)
7. Once Done Partitioning Just Turn Your PC Off
8. Remove Hard Drive and Put PC's back in
9. Plug Back Into PS3

!!!!!!!!!!!Now Here's Were I Spent Most Of My Time Trying To Figure This Out!!!!!!!!!!!

The PS3 has a chip or something that has a timestamp in it, this features data on your last known software version (3.56)
Now this will not allow you to install a fresh copy of 3.55
So i called a buddy of mine who specializes in computers so i gave him a call and found out something i never knew some motherboards have watch size batteries in them witch keep data on a motherboard alive so he told me to take it out
!!!!!!!!!!!!!!!

10. now back to the rest, take your ps3 apart You must login or register to view this content.
11. look for a watch battery and take it out FOR 24 Hours this is important
12. after that put it back in and re assemble PS3.
13. boot up ps3
14. place your 3.55 fw into /PS3/update/ on your external hard drive
15. hook the External HDD to your PS3.
16. Itll ask you to press start and select at same time to recognize software
17. once recognized hit start and select to format ps3.
18. run through the rest of steps

and this should run w/o any issues

I guess you should test it and tell us if it works.

This sounds plausible, if the motherboards battery is visible on the ps3's motherboard

I know what hes saying here

its like if you password protect your bios and pull the battery from the motherboard for a while and put it back in it will clear the password/saved bios settings.

Thats on a pc tho lol

Not sure about a ps3

Might work or it might not lol

Hmm good concept but that is NOT how it works. The battery is only used to keep the system time, and that only. It doesn't reset the NAND at all as that does not require power to store things like RAM. And the nand stores critical parts of the OS so it boots faster, basically structuring the OS for the hard drive. So yeah this would not work and don't recommend taking apart your PS3 trying to do such a thing. PS3 is built differently from a PC if that somehow worked in a PC, it still would not work for a PS3
