Apps won't install or update after I cleared files and data
Have you tried doing a factory reset? In my Samsung Galaxy S4, it's in: System settings &gt; Acceounts &gt; Backup and reset &gt; Factory data reset. See if you can find something similar to your phone.

WARNING: You will lose all your data when you do a factory reset. But since you uninstalled all your apps, it shouldn't be any problem / issue.
