Hi this is my first post on this site but I have been viewing this site for some time now. I recently encountered the problem that when you clicked on Cydia it would load saying "Loading Data" for a couple of seconds then crash back into the springboard. Well I kept looking and looking for a solution and couldn't for the life of me find one. But I finally found one that worked! I will post it below. NOTE: This is NOT a fix for people having problems with ICY that's a different issue. Also I did NOT create this fix, the credit goes to Tech Chronicle. Thanks to whoever figured this fix out. 1.) Use a SSH program or iPhone Browser. I used "iPhone Browser" because I didn't have an SSH program. 2.) Once you connected your iPod Touch or iPhone to your computer and have your SSH program or iPhone Browser up go to your iPod Touch or iPhones directory and find the folder /var/lib/apt/lists (may have to backtrack to the var folder – default log-in isn’t always the root folder where var is) You may opted to back up all of the files. I was deleting simply by dragging them to a folder on the desktop – you don’t have to, but having a way to undo stuff is usually a good option to have. 3.) Delete all of the files except for the partial folder! 4.) Restart your device and have fun! I hope this helps! If this didn't help reinstall (not restore) your jailbreak (don't forget to NOT install ICY) and then follow these instructions.
