Yesterday I updated my Nokia C1-01 from 5.50 to 6.15

After the update. All the files doesn't work. It keep saying invalid app. Mostly all jar or jad Said that. Just the UCbrowser, opera mini from my Memory Card and 2-3 other app works. I try to download them again but after the download it still the same. WHY??????? Plz.... Fix it

Sorry for my bad Grammar(sucks at it)

Hey Kenwai123, Welcome to the Nokia Forums!

Please try install a the latest store client from this link, and try and reinstall all your applications.

If your applications still do not work please try to hard reset your device, You can perform a hard reset by typing the code *#7370# into your phone and using the security code 12345 as default if asked.

Please remember to create a back up of you device using Nokia Suite before performing a reset.

Please get back to me to let me know if you manage to resolve your issue, otherwise I can provide further support.
