Install it from the Recovery Menu
How to access:
1. Shut down your PS3 system.
2. Power up the system, even after the PS3 has started, keep your finger on the power button.
3. When the PS3 shuts down after a couple of beeps, remove your finger.
4. Power up the system again, and wait for the fast double beep.
5. Remove your finger from the power button.
You are now in the Recovery Menu
. Assuming you have the update ready on your USB stick (Folder: X:/PS3/UPDATE/PS3UPDAT.PUP), you can go ahead and chose to update the system.
