AC Question
It came with what I believe was a customized version of kitkat from at&t. I made the mistake of letting it update today and a lot of the features that I liked are gone and the tablet has slowed to a crawl, often locking up for 15-30 seconds at a time. I did a factory restore and it comes up with version 5.1.1. How do I get back to the way at&t shipped the tablet?
