I'm able to download fine. Maybe something on your end is blocking Amazon AWS. As for the false device identification, I don't understand. Are you setting your device as the pixel via the gear icon? I'm being detected as a pixel and able to set it as such.
Are you running a custom ROM that's wrongly identifying your device model?
You gotta provide logs if you want an answer that's not just "works for me".
