for that problem go to the android market and download the super user app, then open it, its going to notify you about an update go ahead and download... once is finished is going to try to install but it will fail so dont worry and follow the instruction provided by the app... that will be reboot in recovery mode and flash the updated su... make sure you are updating the new su the one that you just downloaded... i try those steps and it worked!!! good look
