Rogero Downgrader

This CFW can be installed fine from XMB Update over any CFW version (3.55 --> 9.99)
RSOD screen bypass patch for RSOD machines (it won't fix the RSOD but allows the PS3 to boot fine into XMB)

It does have all the features from Rogero CEX-3.55 v3.7

Downgrading back to CFW3.55 from any CFW version (3.55 --> 9.99) is always possible using the following steps:

• Download the Rogero Downgrader PUP from the links posted above.
• Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP"
• While on any CFW version, go to System Update from XMB and install the Downgrader PUP.
• After the Downgrader PUP installs you'll be back on CFW3.55 (but the syscon version will still have 9.99 in it)
• In case you didn't have it Set Before, Enable QA flag
• Now put "Rogero CEX-3.55 CFW V3.7" on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP" ---> Rogero CEX-3.55 CFW V3.7.PUP
• Start the PS3 and install "Rogero CEX-3.55 CFW V3.7" using the System Update from XMB.
• Once you're back on Rogero CFW3.55 v3.7 you can now install any CFW you want using the System Update from XMB (or Recovery Menu if XMB Update didn't work).
