If the OS has corrupted then you're gonna have to re-install it. In doing so you'll format the handset, so you'll lose anything save to it (not the memory card). BUT if you can still get it to communicate with BB Desktop Manger you should be able to back everything up, including apps and messages.
Check out THIS thread on CB and follow the advanced procedure using JL Cmder. Whilst you're doing that you may as well throw the latest OS on for your model so download that from HERE (don't worry it will be multi language).
