I have the same problem. I updated to 4.0.2 firmware and jailbroke using redsn0w and everything seemed perfect. Now I can't find mobile substrate, and cydia is acting a little weird. Is it possible to just jailbreak over a current jailbreak and see if that just replaces everything?
I think theres just something really wrong with cydia on my phone. Because SBSettings isn't even there if I search it. I'm pretty sure I'm missing a ton of sources even though I installed All Sources. Is there just a way to jailbreak again?
you installed the all sources package? yuck. That can't help cydia. That's a lot for cydia to sift through (or any other program)
I stay away from that.
SBSettings is s big boss source. It comes with cydia.
you can download mobilesubstrate deb file and put it in some directory and reboot and it'll be installed.
to reinstall cydia.... I think there is a deb file you can reinstall cydia using that and terminal (or the reboot method) Can't promise it'll work good though.
Yeah I know it should give me more files haha. And I did the necessary updates. I just have a feeling something went wrong in the jailbreak maybe. I've even noticed that some thumbnails are replaced with black boxes in my photo gallery. I just want to know if i can jailbreak over my current jailbreak. Because that way everything would run smoothly again.
