+1 Thank you! This worked!

I updated to Backgrounder 3.0, and installed BiteSMS and I couldn't launch Cydia anymore. this worked perfectly. Thanks!

[Gugmi01]

thanks man that helped so much! i thought i was doomed

[tellytel]

Yeah mine was working fine until today. I updated and cydia crashed and won't start now. Gonna try deleting the update files.

Will the updates come back though??

i updated to 3.0 and had no issues at all until i installed a ringtone package. flashed, rebooted and cydia would open and immediately close since it didn't finish installing the package; i'm guessing this is what deleting the 2 files there gets rid of the unfinished installation.

on 3.0 the apt-get command doesn't work so i used "cd" to change directories ("cd var" for example or "cd ..") to get to the var/lib/dpkg/updates folder.
"ls" will list the files and directories in the current folder
"rm ???" will remove ??? for example "rm tmp.i" deletes the tmp.i file in that updates folder

these commands are obvious to a lot of you but people like myself have to find them somewhere

I am new to iPhone and to jailbreaking. Much like the others, I am unable to launch Cydia after having used it for a couple of days and installing several themes, ringtones, etc.

I initially did my jailbreaking on a PC since that's where my iTunes library is, but I thought I would revert back to my MAC if that will help overall.

Is someone willing to explain to me, step by step, how I can access the "browser" and or where to enter "cd" to change the directories? If not, any ideas of where I can get a Jailbreaking/Cydia for dummies manual?

Thanks

Well, I give up... ive had it... congrats to all you guys who had this same problem and were able to fix it simply!

I totally restored my phone as new (3.0) a week ago, spent countless hours getting all my settings and apps back from scratch, been using Cydia all week. Then today, for no apparent reason, i'm back to Cydia refusing to launch again.

I tried to re-redsn0w using 7.2... no dice

I deleted all the Cydia repo files... nada

I opened the cydia.log file... blank

I wanted to try this with mobile terminal:
apt-get remove cydia
apt-get install cydia
But Mobile Terminal wont launch either, loads the default screen then crashes, exactly like Cydia does.

The last thing I just did was re-redsn0w AGAIN, but this time I had it install icy too... and icy works fine and shows all my installed Cydia apps. I think i'll just stick with icy.

I even force-removed and re-installed Cydia with icy, I also reinstalled mobilesubstrate, Cydia and Terminal STILL will not run.

I NEVER thought i'd say this but.... screw Cydia! This is just ridiculous, and nobody seems to be working on anything to resolved it, and if they are, they sure are tight lipped about it!

***UPDATE:
Suddenly I have a cydia.log file with some content... this is what it says:

dyld: Library not loaded: /System/Library/PrivateFrameworks/MessageUI.framework/MessageUI
Referenced from: /Applications/Cydia.app/Cydia_
Reason: image not found

I took a look, and this directory doesn't exist. but it DOES exist in /System/Library/Frameworks/
Anyone have any thoughts about this?

***ANOTHER UPDATE:
This just keeps getting better!! Now the SBSettings utility wont launch either... the overlay still drops down, and the toggles and dock apps still work, but if I hit the "more" button, it loads the default screen, then crashes (just like Cydia & Terminal). It still worked after Cydia and Terminal stopped working, so apparently my phone's OS is gradually self-destructing. I'm not sure landscape email & text is worth all this BS!!

you get into a program called mobile terminal to access the phone and use the "cd" commands and such. it's similar to using DOS on windows

then you use the "cd .." and "cd foldername" to get to the folder you need

[rz.]

Im having the same problem. I tried deleting the files in the updates folder, but it turns out the folder is empty -.- , my cydia still doesn't work.

[setkeh]

Hey dudes and dudets I jailbroke my iPhone 3g 3.0 using redsn0w on windows 7 I managed to get openssh and mobile terminal installed
before my cydia messed up I could always launch it but on ocasion it would randomly crash out I checked /var/lib/dpkg/updates but the folder was empty so I then opened mobile terminal *please note the following can be done via ssh if you do not have mobile terminal* I then run "dpkg --configure -a" this has seemed to slow the crashing majorly I would also recomend installing apt-get just incase so you can still install and update pakages via ssh and mobile terminal using the following commands "apt-get update -y" and "apt-get install com.repo.package -y" other than the minor cydia issue that seems to be semi resolved and a little more lagg than 2.2.1 3.0 is kicking bottom and finally make sure the first thing you do is update cydia hope this helps have fun and stay safe peace

I think I determined what the cause of the problem was... its somehow related to Air Sharing or eWallet.
When the 3.0 updates were released, and then a 2nd 3.0 update for Air Sharing popped up last saturday, the App Store app error'd (as usual) trying to upgrade it... after that (in both cases) is when my Cydia stopped launching.

If you end up doing a full restore again (like I did), it will probably be in your best interest NOT to let the app store (via your phone) try to update either of those apps. Or any other app that has a desktop utility or wifi sync function associated with it.

To update those types of apps, SSH into your phone and delete the entire app folder and sub directories, then let itunes sync and reinstall it. Then re-sync your personal data back into those apps.
