Hi, so can you really downgrade the 3.55 firmware as i am getting a MINIMUS AVR USB DEV BOARD to downgrade mine to backup all my games please let me know if i can please?
yes unless you have a ps3 that came with 3.50 preinstalled. see this: http://www.ps3news.com/forums/ps3-ha...le-116965.html
so i can use a minimus to do my downgrade i also have a use drive break ps and with the iphone thing my will not work as iboot dose not let me put it in service mode i followed all the vid on youtube on this and come up with nothing??
yes you can use minimus. in the thread I linked they say downgrader dongle which is just a jb device with downgrader firmware on it.
