I have MOST of the equipment to downgrade/jailbreak.
SD Card Adapter, SD Card, Screw Drivers, USB, PC/Laptop, PS3. (Getting E3 NOR Flasher REAL SOON.)

The only thing I'm missing is clear instructions (and some files/equipment). Check the spoilers to see what I have, and please reply with links to get the rest of the things I need. I could really use your help on instructions also.

1. Disassemble your PS3.

2. Install the E3 Flasher (You can look on YouTube to watch how it's installed).

3. Put the update.bin on the SD card, put switches 3 4 5 6 up then power on the PS3, insert the SD card and press start, this will update the flasher.

4. Power off the PS3 then put all the switches down except the third, power on the PS3 and press start (while the SD card is in the flasher), this will make a backup.

5. Once the backup is made, take out the SD card and put it into your PC (do step 3 and 4 three times but take the backup off the SD card every time you put it in your PC).

6. Check the backups in PS3DumpChecker.exe, if their all good, proceed to the next step.

7. Get flowrebuilder5.exe and byte reverse a dump. Once it's byte reversed, proceed.

8. Put the SD card in your flasher, put all switches down, power on the PS3 then press start.

9. Once it's done, restart the PS3 and make sure it boots (if not, flash one of your original backups then try something else to byte reverse your dump).

10. Reassemble your PS3 and power it on.

11. Install Rogero Downgrader (you may have to QA Toggle, can't exactly remember) then 3.55 OFW.

12. Install a firmware of your choice, if your going to DEX, install Rebug.

If I missed anything or if anything is wrong then someone can correct me, but that's all I did to downgrade. Good luck!

I can call you on skype and walk you through the process if you would like

Once I get an E3 Nor Flasher, lets chat Skype: scythedax
