Not 100% sure if this will work for you but it has worked for me.
Try booting into safe mode to re install your firmware
Step 1) Hold down the power button in till the ps3 turns on and turns of again.

Step 2) Hold down the power button but stop after you hear two fast beeps.

Once booted into safe mode try to reinstall your firmware with "System Update"

Ohh shit its working thanks man! <3

i just hope it doesnt update my ps3 to 4.76 xD
