Apple iPhone SpringBoard is not loading/Apple logo freeze/struck while loading

Some applications may modify the Springboard configuration file, so while booting up if it encounter any error, springboard wont load but the SSH and OS will be running.

Using iPhone Explorer or WinSCP download the file /System/Library/LaunchDaemons/com.apple.SpringBoard.plist

Using the online tool at http://iappcat.com/plist/bin2xml convert the downloaded file into XML format.

Open the converted file using Notepad/Wordpad. Find the key DYLD_INSERT_LIBRARIES. check the string immediately after this entry. Check for any suspicious library which may fail to load. Semicolon (;) is used as delimiter to seperate multiple libraries. Delete the library which is not required. Copy back the modified file back to iPhone, XML file can be directly copied to iPhone. Restart the phone :)
