My Android has not been able to sync contacts since July 29th giving the error Invalid service state. Online backup assistant is current, there are no listed contacts in my phone through typical app. All contacts are available by searching through the phone app. At or around that time The phone had a very low battery and when recharged had lost all of its screen memory, No background, no HTC Desk Clock widget, no apps on any screen. All features of the phone function with the exception of Backup Assistant and Desk Clock Widget. Android 2.2 Software Number 3.26.605.1 Harware Version 0003.
Any help would be appreciated.
