Dell Venue stuck on Android 4.4.4
Had an issue with Dell Venue 7840 tablet's battery, sent device in under warranty. They said they needed a part and asked if it was OK to send a different one instead. I agreed.
The replacement Venue 7840 came with Android 4.4.4 version. Cannot get it to update to new version. Tried factory reset, restart, system update (of course)... none worked.
Anyone know how to solve this problem?
