I've had my PS3 on OFW 4.53 for a few years now, my son just accidentally upgraded to 4.65 today so the MCU v2.0 no longer works. I was able to upgrade to both Firmware 2.2 and 2.4 but both had problems. With 2.2 I was getting the error that COBRA/cobra.db could not be found. I tried both the database that I had installed with the MCU v2.0 and the new 05-03-2015 database available from the website. Is there another database that I should be using instead? With 2.4 I am able to get into the Cobra Manager/Browser, but when I go to load a game I endup with "An error occurred during the start operation (80010017)" Thanks in advance!!
