Playstation 3 locks up when updating
As a Play Station 3(PS3) and You Tube fan, you may always use PS3 You Tube app to make better use of the PS3 controls with an improved user interface and option to pair the app with mobile phones to use as a remote control.
The process of updating is almost identical to that of the Play Station Portable, Play Station Vita, and Play Station 4.
The software may be updated by downloading the update directly on the Play Station 3, downloading it from the user's local Official Play Station website to a PC and using a USB storage device to transfer it to the Play Station 3, or installing the update from game discs containing update data.
This is similar to the later Play Station 4 console which also has two APIs, the low level GNM and the higher level GNMX.
Unlike the Software Development Kit (SDK) for mobile apps, Sony's Play Station 3 SDK is only available to registered game development companies and contains software tools and an integrated hardware component.
Scroll until you find the Saved Data Utility (PS3). Once you're in the Saved Data Utility, find the Call of Duty: Black Ops file. You will lose all of your campaign progress, along with the names of your custom classes, but all of your classes should be the same, and no online progress should be lost.
