PS3 error, can't even get on main menu?

Question

I updated my Ps3, well, it got to about 71% then kept saying error, I can't even get on to the menu anymore. It errors every time?

What should I do?

All help appreciated. (:

Answer 1

switch it off at the rear, and then back on to stand by, now turn it on by holding down the power button on the front for 5 seconds untill it beeps at you, this resets things to factory settings (if you use HDMI it should pick it up and ask if you want to use it) (oh and don't worry does not delete data, just reverts all settings).

it may help, but its the only thing i can think of without saying ring Sony Tech Support
