This installer includes everything you need to install Signed 5.03 kxploit v7 + 5.03 Prometheus-4.
Just select your PSPDrive and install it.
You must upgrade by that way:
*to install chickHEN,you must have OFW 5.03 installed
*launch chickHEN (go to your PICTURES and scroll very fast down)
*.:: PSP "Crash" ::. (if not try it again and again...)
*chickHEN is installed
*install CFWEnabler under Games -> MS -> CFWEnabler
*Turn off your PSP (FULL SHUTDOWN)
*launch 5.03 kxploit under Games -> MS -> 503kxploit
*install 5.03 GEN-C under Games -> MS -> GEN-C Updater
*PSP Restart -> GEN-C is installed
*install 5.03 Prometheus under Games -> MS -> 5.03 Prometheus Updater
If you turn off your PSP (FULL SHUTDOWN) you need to launch 503kxploit and you're again on 5.03 Prometheus-4
Statutory Warning: Iím not responsible if you brick your PSP following these steps.
