OK I just updated the firmware to version 2.3.6 and ever since I have done that I get the error message "process.com.android.phone has stopped unexpectedly. Please try again". Has anyone got any suggestions? I think I may have put the wrong version on my phone as I was using XXKI4 and it now says XWKK5. Any suggestions? Thanks Edit: Managed to put my phone back to its previous state with Android 2.3.5, but what version do I need in order to get android version 2.3.6 and Checkrom Revolution v4?
