I jailbreaked my friends iphone 4s and it worked fine but when I am trying to install tweaks the sub-process returned an error code thing came up on every single tweak. I tried to get into the files with ifunbox but its jailed. So I tried to un-jailed it but I couldn't get the automatic SSH ramdisk tool to work to get the information. Please help :) sub-process / usr / bin / dpkg returned an error code (2)
