46w ago - Following up on my
PSN / SEN Enabler & Disabler 4.20 release, I have now upgraded them to version 4.21 and included
ReActPSN compatibility support, which is not mandatory for log in SEN.
It also includes a GUI for enabling PSN / SEN so if something is wrong it will restore your PS3 files preventing a RSOD on the PlayStation 3 console.
ALLOW SEN ACCESS - INSTALL ONLY PKG FOR YOUR CFW
SEN Enabler & Disabler [4.21]
This enable (4.21) or disable SEN access for your CFW, simply install *ONLY THE PKG FOR YOUR CFW* (CFW Kmeaw = PKG for Kmeaw) and run it in XMB, you will see the menu, first if you wish to continue choose "Yes" or if you wish exit to XMB choose "No".
If you continue program will ask you if you want enable fix, and for disable in this screen choose "No" and you will be able to disable fix. At the moment of enabling fix, it will create a backup of your dev_flash files to restore and prevent RSOD
