I was able to use Drive application a few times since I got my N9. Yesterday I discovered that Drive application stopped working, it just sits on the loading screen forever. Maps application is working fine. I tried rebooting many times. I deleted all maps and redownloaded them. I even manually deleted cities folder in home/user/MyDocs. Nothing fixed the Drive application. I finally flashed to PR1.1 and STILL Drive application is not loading. Do I have to flash eMMC image to fix it? Has anyone experienced this problem before?
