Im not gonna explain how to do it... Its somewhere on google. Use it for a change...

didn't you back up your cert CA27.

what happens if i do not change them back ?

1. First Install Dev_Blind.pkg on your PS3

2.Run Dev_Blind

3.Go On FTP (BlackB0x)

4. On Your Computer go on your FTP Client (FileZilla, Core FTP)

5.Go to /dev_blind/data/cert

6.INSERT ORIGINAL CERT HERE

7.Reboot your PS3

8.Go on Recovery Menu

9. Install Original Firmware 3.55

10. You are on the Original firmware now you can update and go on 3.60


Give Thanks REp +

i aready know how to do it was just needing the cert and wanted to know what happens if you dont replace it back to normal then update

but thankyou anyway

im not sure if anything happen, but replace original certs just to be on the safe side

I think you cant connect to PSN anymore... There was a guy on here who had that problem and fixed it by recovering everything so it isnt hard to fix if you mess it up, but why take the risk... Replacing is easy so just do that!!
