Hi, slightly off topic but i didn't know where to post. I hastily replaced cer27 not in dev blind but in home/data/cer i think. If i reinstall ofw 3.55 will it replace original cer. I think i still have a patched cer24 from the days of charles. hope this makes sense i just want to put all my cer files back to stock. thanks in advance.
The instructions are on drizztbsd's github (dont know if i can post the link, google it) and have already been posted here:
Install dev_blind.pkg and OpenPS3FTP on your PS3 (using FTP, external USB or what else)
Launch dev_blind and make it mount the flash
Connect via FTP to PS3 (using username root and password openbox)
Go to /dev_blind/data/cert
Rename CA27.cer to CA27.cer.bak
Put my CA27.cer as /dev_blind/data/cert/CA27.cer
Set the PS3's PRIMARY and SECONDARY DNS server to your PC's IP address
Reboot your PS3
Enjoy with PSN
I didnt used dev_blind.pkg or FTP, i used multiMAN, it has a built in option to mount dev_flash as dev_blind, other than that i followed the instructions.
If you used f*ckPSN before (on a version lower than 0.7)you probably have a modified CA24.cert, if so replace it with the original CA24.cert
Make sure your firewall isnt blocking a ruby.exe process and that it has permission to act as a server, and if you keep getting some kind of error you might want to check to see if you've got any programs using ports 80 or 443
Dont forget to Edit your Primary and Secondary DNS server to your IPv4 address (to check your IPv4 address: Start - Execute - cmd - ipconfig /all ) and to reboot your PS3 after you edit your Primary and Secondary DNS Server
