Protected Z4 Tablet from Amazon Help!

A week ago I purchased a used Xperia Z4 tablet from Amazon. I had been wanting this tablet since it was announced and when I saw a used one for 6 I couldn't resist.
When I received the tablet it was in like new condition Plastic still on the screen etc., but when I powered it on it went into protect mode.
Oh well I figured I would just go on XDA an I would have it fixed in no time. Well I was wrong lol.
With this new MXTP software at bootloader level and no way to unlock root or anything else once activated, I gave up and called Amazon. They couldn't help me get out of protect mode. I called Sony.
Sony told me that I could send it in to be repaired. When they tried to create an rma they didn't know how because the Tablet has not been released in the USA, and it is not in there system.
They would have call there repair facility and figure out how to get it repaired.
After a week and a half of phone calls, Sony finally told me none of there repair facilities in the USA know how to work on this tablet. And They could not tell me where I could get it fixed.
Does anyone know how to fix this? or where in the USA I can get this tablet fixed?
Thanks in advance.
