PS3UPDAT_Rogero_CEX_4.46_v1.01_Downgrader.PUP (MD5: e66fa806125bd9f0b7698f00324a4cd1) - Here's the PUP that have 9.99 as the built in version, it's basically a 4.46 downgrader, it will install on any version CFW up to 9.99 and will get you back on 4.46, in your case where your PS3 have 3.56 minver you can't use the normal 3.55 Downgrader, so this PUP will be a simple solution for you to get on CFW4.46.
N.B: Please people don't use this PUP for normal Updates, it will fill your syscon version with 9.99 and you need to Downgrade back to 3.55 and dehash in case this PUP was used, but for 3.56 Minver users the 3.55 Downgrader can't be used, that's why I posted this PUP just to help him install CFW4.46 without going into much details on how to dehash the 3.56Minver PS3.
