I have 16 gig c60 with stock Rom & 4.1.1, unlocked and rooted.

Over 8gb free. Apps won't install from store, New or ones to update!

I have searched & found some ideas for solutions, none have worked.

Lucky patcher fix = no
Wiped cache and dalvik cache = no
Clear play store data = no
I even uninstalled about 100mb of apps = no

I am annoyed and getting frustrated. There has to be a known issue/fix.

Anyone?
