Hello! After rooting my phone I uninstalled the stock Messaging app with Root Uninstaller. I made a backup of the Mms.apk file. A few days later I tried to reinstall it, but when I run it, it only says "Application not installed". I've been searching around for hours, tried copying the backed up apk to the /system/app folder, changing permissions, rebooting, flashing various zip packages, wiping the delvik cache, etc, but still it says "Application not installed". When I go to the /system/app folder with Super Manager, the copied apk file is displayed as Messaging(No install) ?! screenshot: hxxp://i49.tinypic.com/33zd1jb.png I also tried with some other apks I found online but it doesn't work either. I know I could flash the ROM, but I'd like to use that as a last resort. Any ideas/suggestion would be greatly appreciated.
