Okey who ever did the mistake of updating too 3.56, theres still hope. If someway u get your ps3 bricked. You can use lv2 file 1 and the OFW on a root of your ps3 and it will install it. Will not provide links, you can search for it.
And now. does anyone know how to get out of service mode. I accidently got it on my 3.56
