OK so first of all, i'm VERY computer/phone/tablet illiterate. I can do whatever you guys suggest but please say it in plain, stupid english so a guy like me can understand haha. About 6 weeks ago we got a galaxy tab A for my 5 year old, he watches some youtube, plays a couple games and learning apps, and that's about it. It's his, never gets used for anything else. It was bought new, open box from ebay from a seller with great feedback and good feedback for this particular tablet. So i have no reason to expect i got a lemon (at least i don't think.. yet) So anyways here's what happens: I check for an update, It finds one, downloads it, gives me the options to install now, later etc.., go to install, does the restart, shows the android guy and the percentage bar for installing the update... and then usually between 1/3-1/2 way through the installation of the update it shows the dead android guy and says it has failed and to contact a samsung service center. I have no other issues with the Tab. I also do NOT have an SD card for it yet... does this matter? i have tried charging to 100 percent, keeping it plugged into the charger, power cycled quite a few times, nothing. thanks in advance everyone!
