it all started when i just connected my phone to the usb cable, a message just popped up at my cel stating that my memory stick is corrupted... i chose no then i immediately checked my application/games directory and found out that i cant access it and when i tried installing a java game, the "operation failed" message keeps showing up, i tried formatting my m.s. and eventually using the master reset of the phone and also tried SEUS but it didn't fixed it and i am still getting that operation failed message every time i tried to access the two directoriesor tried to install a java game/app.... Please help :'(

do masterreset and if that doesn't work reflash it
