Simply!!! resign eboot for 4.21 with true ancestor or similar tool......
He's right about the EBOOT. Im on 4.21.1 rex too. Only issue I have is trying to get onto server. "The Call of Duty: Black Ops II server is not available at this time. Please try again later or visit..."
In my REBUG toolbox: system mode to REBUG, the XMB operation mode to RETAIL, and last option on CEX/QA.
Do I need a disc in drive?
