I have been trying to upgrade from CM10.1 stable to CM10.2 stable. I am using CWM 6.0.2.9 internal. I originally flashed both CM10.2 and Gapps jb-20130813 and get stuck at a blank screen. I then restored to my 10.1 and used the CM updater to install 10.2. It came up fine but google apps were not working (gray internet connection instead of blue). I rebooted into recovery and flashed the 20130813 gapps zip file and once again was stuck at a blank screen. I tried clearing the cache and dalvik but it didn't seem to help. Am I using the wrong version of gapps or something?
