I have refrained from commenting in this thread up to this point but I think it's about time to say something.
My A3 came with a Quick Start Guide and a sheet that stated "Please visit
www.Amiko-A3.us for guides and instructions" as well as the FCC Part 15(b) compliance notice. Knowing I was going to receive the A3 I had already read and downloaded all the guides so I had some idea what should be done. I still went to the indicated web site and selecting "Guides And Instructions" and was greeted with this:

The very first thing I did was insert a microSD card into the A3 and make a full backup of the system and apps to it, just like the instructions say to do. I also made a backup to a USB flash drive just for insurance. As the web site says, the A3 does not operate like any other STB and I wanted to be sure I could start over if I screwed it up during setup.
Everyone makes mistakes (been there, done that) and should learn from them. If a backup of the A3 had been made before any updates were applied the OP could have just restored it and started over when it was discovered that a European ROM had been installed. Since the Americas ROM adds features and functions not in the European ROM, the EU updater won't load an Americas ROM. The EU update replaces the Americas apps with European versions, maybe great for Europe but not so good for FTA here in the Americas.
The A3 is an Android-based computer and not a MicroHD, MiniHD SE, Pansat, S-10, or any of the other "traditional" STB's. It requires different procedures and you have to learn new ways of doing things.
There have been a few bumps in the road but overall I've had less trouble with the A3 than any other receiver I've owned, and NO, I have no connection with any of the Amiko dealers or the distributor except for being a paying customer.
