I have tried editing my build.prop to match both Kindle Fire HD and Kindle Fire HDX but that didn't fool Amazon. I also tried to fake my GPU & CPU information for Appstore using GLTools v1.07 (graphics optimizer) 03/06/2014 with no results.
Do you guys have any information how Amazon determines your device type? Or could somebody of you upload the .apk for GTA: San Andreas (it is under 100MB, just an installer)? I have a license for it, so the downloader would work
