Just using the same answer that I posted from another post =P
You need to install QA flag and then run the program. Your ps3 should beep few times then go back to XMB. Afterwards to verify you QA flag you PS3, navigate to Network Settings and press the button combination (L1 + L2 + L3 + R1 + R2 + dpad_down) at the same time. You should now see the hidden menu : edy viewer, debug settings and install pkg.

Now go to debug settings>system update debug> turn on
Go on safe/recovery mode to do system update

Now install 3.55
