Fixing "Unfortunately, DMG has stopped working" on Lenovo tablets My Lenovo IdeaTab S6000H tablet running on Android 4.2.2 Jelly Bean had worked fine before yesterday when suddenly it turned off, and after a restart, it has shown this message periodically:

Unfortunately, DMG has stopped working

I also did a factory reset, but after turning it on, the same error message has been showing again.
How to fix this error?
You should check the mounting state of sdcard, maybe it’s broken. Suggest to call the customer service phone for examining further.
