Without reading quickstart guide (and no intent in doing it):
You have a 1 year return warranty in case of the product failing.
Did your X1000 break ? Doesn't seem to be so
Did OS4 fail to work in the scop that it was supposed to work when you bought the X1000 ? Hmm, everybody pretty much knew it was unfinished and progressing at a snail's pace back than, so good luck trying to proove that.
Is OS4 even part of what is warrantied by AEON ? Doubtfull
Also such a refund would only happen AFTER you returned the X1000, not include any shipping cost and be reduced for the time you allready used the product.
