I purchased the Galaxy Tab A (T580) today and am already in trouble. The Odin of CF-Auto-Root seemed to go fine (ie, it passed), but when I installed TWRP at Play Store things went amiss. First I didn't know whether to download the img or the img.tar. I ended up downloading both, but could find no step to actually flash either. Now I'm getting the message: Blocked by FRP Lock. How do I recover from that? Thanks for any help.
