I have a B&N Tablet (BNTV250, 16GB). I recently installed CM10 successfully. I can download apps all day long, and I can browse the 'net and all kinds of good stuff. But, I can't download files. I went to a woodworking site where I had purchased a few PDFs of interesting projects. I can download them on my PC (Linux, Kubuntu 14.04) as many times as I want to. I go the same site on the Tablet in Android (CM10) and in Firefox i just get a Fail. In the standard browser I get an error that indicates that I have to download to an SD card. What is up with that? Is it really true that there is no way to download data files (NOT apps) and store them internally with all the space that I have available on Tablet? Is Android purposefully set up to not allow downloads internally to a system? I'm not complaining, I'm just thoroughly confused - and hope I just need to find some box to click on to make it happen. I've tried to ask the same question over on XDA-Developers in the Nook Tablet forums. the sound of crickets is deafening, but no answers. Thank you.
