Is my Kindle 6 a boat anchor

Apologies in advance if I post this in the wrong forum.

I just dug out my old Kindle Fire (Kindle 6) with a D01E S/N prefix. I don't even recall when I bought it... Haven't used it in years. It turns on, and all my old books and apps were there - but I noticed that Amazon seems to have completely disabled any ability to update its contents or software. Not my mailing to it, or using setup, , or anything I tried. Even the browser cannot load ANY websites. However it will still connect to my Wifi, and I can see the drive contents when connected to my Win10 laptop via USB.

So, being the forever tinkerer, I was wondering - Can I do ANYTHING with this? Just for fun? Can I turn it into a basic, updatable, Android color e-reader?

Or should I just toss it into the electronics recycle???
