I had a little bit of a tricky time with this as I found that they only way I could get it load was using a microsd card not an external USB stick. Once I had that sorted out, i found that the instructions were quite clear. I am finding that the box works quite well. I was really pleased to purchase the box as a Marhsmallow device, get an OTA for a later version of Marshmallow and now be able to update to Nougat. Well done and thank you.
