(adsbygoogle = window.adsbygoogle || []).push({}); HOW TO DOWNGRADE:
1. Install the PS3JB App (v. 0.08.0001)
2. Open the PS3JB App on your calculator. (APPS->PS3JB)
3. Choose Option "5" (Options)
4. Make sure "Stage 1 and Stage 2 Payloads" is set to "none". Make sure "FW. Compat. Opts" is set to "none". Make sure "Use Device 6" is set to "No".
5. MAKE SURE "EMULATE JIG" IS SET TO YES
6. Save your configuration.
7. Connect your calculator to your PS3 and press option "1" (PS3 Jailbreak) on your calculator.
8. Do the power cycle like you normally would to jailbreak your PS3.
9. You may see some screen flickers. You will not have a picture on your screen. The PS3 will shut itself off.
10. Format a USB flash drive. Make sure there is nothing left on the flash drive.
11. Copy over the modified 3.41 update (PS3UPDAT.PUP) and the first Lv2diag.self file onto the root of your flash drive. There should be nothing else but these two files on your flash drive.
12. Plug the flash drive into the right-most USB port if your PS3 is laying down, or the top USB port if it is standing up.
13. Power on the machine. Don't do the normal Jailbreak power cycle. Just power it on. You will get no picture. You will have to wait until it shuts itself off agin, which took me about 10 minutes. DO NOT get antsy and think it froze on you and shut it off prematurely. Give it up to an hour before doing anything drastic.
14. Once the PS3 shuts itself off again, plug your flash drive back into your computer again and delete the "PS3UPDAT.DAT" and the "Lv2diag.self" files. Once deleted, copy over the second Lv2diag.self file to the root of your flash drive. Again, this should be the only file on your flash drive.
15. Once the file is on your flash drive, plug it into the same port you had it in before in your PS3 and turn the power on. Again, just a normal power on, no Jailbreak power cycle.
16. It will stay at a black screeen until it is ready and then shut itself off. Once that is done, remove your flash drive.

Congratulations! You are now done!

Just did it and worked really smooth!
Thanks,

Did the same, except the payload part didn't work for me. All I did was uninstall PS3JB from my TI84 and installed the previous version (with default payload) and it worked perfectly.

Nice tutorial!

one question do you have to put the root USB > PS3 > UPDATE...
or just the root of USB > .PUP file here?

Just put it on the USB as told

This is just C+P..
Atleast add your source .
