Hello, i have a SLIM CECH-2011A 120Gb (stock hdd), in the past i had successfully installed and booted RED RIBBON RC4, i removed it since i needed the hdd space, at the moment i have followed the guide posted here http://wiki.gitbrew.org/wikibrew/PS3..._PS3_models.29 i used the PS3 Dual Boot GameOS/Linux CFW 3.55 22GB PUP, installed it, restored the system, followed every single word on the tutorial, yet when i boot to petitboot and choose the 1st option i get the message "failed: kexec /var/petitboot/mnt/sr0/live/vmlinux-2.6.38-powerpc64", also after loading into petitboot if i choose the GameOS option it doesnt boot GameOS, it shows at the bottom of the screen "Running /usr/sbin/ps3-boot-game-os..." and stays frozen there, is there a way to troubleshoot it? ive tried with other FW PUPs and at the end of the proccess they all deliver the same result, i do not understand why i cant install this OS if i was able to do it before, is there something that can be done, i tried posting on gitbrew forums but my request to register hasnt been approved yet, please help
