Now that you are on 6.60 Official, you need to re-enable homebrew capabilities.

You cannot jump directly from 3.52 to 6.60 custom firmware. First, you must return to Official Sony Firmware (OFW) 6.60.

  • On PSP (now OFW 6.60), go to Game → Memory Stick™PRO-C2 Fast Recovery (run once to install CFW temporarily).
  • You’ll see “Press X to launch” – press X. PSP restarts into 6.60 PRO-C2 CFW.
