Good for enterprise - unknown error code during application install -24
I have the Galaxy Tab 3.GT-5200. I am trying to install Good for enterprise as i use my tablet for work.
The first time it installed i got package invalid. I tried to re-download it again and since then I get unknown error code during application install -24.
I have been reading the post but itís all for rooted devices and I canít root my device as good wont then install and wonít be activated.
Action I have taken
1. Factory reset Ė Please not again
2. Cleared cache from Google play account
3. Deleted Google account, Rebooted and then added.
4. I have deleted the/storage/emulated/0/Android/data folder.
I am out of ideas. I know if the device is rooted you can delete another data/data folder but I cannot get to that.
