yesterday i have jailbroken my iphone 4 IOS 5.0.1 and installed cydia. There were no problems everything worked. But today i cant open cydia it shuts down after few seconds. i tried to rejaibreak restored from backup but it still crashes.
Which version of redsn0w are you using? You should be using 0.9.10b3 for mac or 0.9.9b9d for win. It sounds like your using an older version with a tethered boot.
Yer thats the correct version...just testing you Since you have already completed a restore but restored a backup the only thing I can suggest to try is to restore a clean 5.0.1 but dont restore your settings etc. so clean 5.0.1 install, then jailbreak..?
Now it works but i havn´t done anything But now when i will download something there is written: "I wasn´t able to locate file for the perferenceloader package. This might mean you need to manually fix this package."
have u installed winterboard or something? try: Reboot phone then / remove then re-install any packages.
I've had this happen several times - Don't Fret... all you need to do is Reboot the phone (if you have SBSettings, do it from there, if not, hold Power Button... slide to power off) then Reboot - and then try Cydia again, you should be fine. It's strange that this happens.. but anytime it happens to me, I just reboot. Typically happens to me on a Daily basis, even after a fresh restore/jailbreak. Hope this helps!
