Cydia crash error repair

After the Iphone is jailbroken, cydia crashes. Once it is turned on, it will return in seconds. cydia errors may cause headaches. How can we fix Cydia? The Cydia crash repair Tutorial is as follows: 1. Use iFILE or ifunbox to enter var/lib/apt/list and delete all files in this folder (the folder is not deleted). The contents in the partial folder under this directory are also deleted, but keep this empty folder. 2. Use iFILE or ifunbox to enter/etc/apt/sources. list. d directory to delete cydia under this directory. list contains the list of sources you have manually added, which are used for backup, editable, and deleted individually. 3. Go to the/var/lib/dpkg/updates directory and delete all files in the directory to fix cydia. 4. Use iFILE or ifunbox to delete the var/lib/cydia/metadata. plist file, which stores information of all added sources. Some stubborn information is hidden here. Even if all the preceding three steps are executed, metadata is added when you re-enter cydia and add the source. plist will work again, restoring stubborn information again, which leads to cydia crash. Therefore, deleting it is a fundamental solution. 5. When you enter CYDIA, you will find that all sources are missing. Add them manually. Add whatever you want. Originally, cydia has its own source. I recommend that you only add the image sources of saurik and bigboss. You also need to add ultrasn0w to the children's shoes to be unlocked. The three addresses are: http://apt.weiphone.com/cydia/saurik http://apt.weiphone.com/cydia/bigboss http://repo666.ultrasn0w.com 6, if not, re-install CYDIA, the following attachment with ifunbox to the iphone, IFILE installation can be. 7. If the problem persists, simply delete cydia and reinstall cydia after jailbreak. Of course, you do not need to brush the machine or affect other data. 8. Finally, [the ultimate method is coming] If you are not lucky enough to solve the problem, flash the machine. As long as you have a SHSH backup, as long as you are not a hardware fault, this is an absolute solution to the problem. Of course, the data is cleared. If you use itunes to synchronize backups before flash, you can restore most of the data, but some software does not save the data.
