I have a "Security Unlocked" HTC 8x that will not download updates. Is there a way to push updates to it?

Question

So I destroyed the LCD on my first 8x and had to get a replacement. I bought another 8x on ebay and it turns out that it is "Security Unlocked". I apparently have full access to the bootloader and can enter all sorts of fun modes by pressing buttons
during bootup. But I am unable to install any OTA updates to the phone. When I search for updates on the phone it tells me that my device is up to date (my current version is 8.0.900.568). If I attempt to install language packs, I just get an error "Couldn't
download. Tap to retry".
When I boot to "bootloader mode", which displays lots of numbers and bar codes, the indications are that this phone was shipped from HTC this way and was not hacked by a previous owner. I suspect the ebay seller got it like this new. The ebay seller
has not responded to any of my messages.
HTC support has been less than helpful (though the support agent did try his best to help me out) and Windows Phone support believed I was referring to "Developer unlocked" and said I would probably have better luck here. I have registered the
phone with Visual Studio and have so far been unsuccessful at finding any way to push updates to the phone directly, but I'm not sure at all where to look. Right now I just have VS Express with the WP SDK installed, but I can install VS 2013 Pro on here if
I need to.
Since it is security unlocked, I supposedly have access to all sorts of gooey parts of the phone, including potentially the OS partition. I have the technical skill and ability to perform whatever official or unofficial or unsupported tasks might be involved
in getting this thing to work like a normal phone. I just don't have the esoteric knowledge to do so.
So the original question - are there any hacks I can do to make it function like a regular phone and download updates OTA? (To be clear, I am not trying to hack the phone, I'm trying to UNhack the phone.) Is there a way to push updates with Visual Studio
or in some other way?

I am sorry that you don't find the answer to be correct. In THIS forum, telling you that you are in the wrong forum, and suggesting where to post for correct answers, or indeed any support, IS the answer.
I'm also sorry that you purchased a phone that you are having trouble with. If the vendor cannot help you (HTC), and the eBay seller cannot help you, then you really do need to either follow up with the forums Ken suggests, or the HTC forum, or with eBay.
