OoZic thanks for your help..
maybe the problem about recognization of /dev/ps3dd part is related to
Kernel file of harvard ubuntu distro but the read-only file system errors not which is exactly the origin of the trouble i reckon..
the link you given to me about the freebsd is the same link where i downloaded the live cd before...
and thanks for the freebsd info because i dont know linux
and Can I install that RedRibbon RC5 without petitboot loader which isnt working properly on my console you know those read-only file system errors and i also turned back to my 3.55 KMEAW CFW,
installed my games and apps again
i mean could i use asbestOS 1.5 or bootOS2.1 and lv2patcherv9 combination to install RedRibbon RC5 ? i dont want to get back CFW355-OTHEROS++-22GB which will destroy all the HDD again and takes time ...
If your answer YES then i ll try it one more time otwerwise i have to say Good Bye Linux because i dont need you.!
