this would work, but you'll soon find out that there is even more involved. IMSI, IMEI etc.,the actual act of downloading... is the simplest in the entire chain. look at it like carding... pressing "buy now" is the most insignificant part of the deal. cloaking, disguising, the time put into this is tenfold that of pressing "buy now". same applies to app installs. "install" is the easiest part...
Think about this to.. i try using android emulator but will waste your time..
because i think gplay not only detect data+cache.. but HW ID to.. so reinstall bluestack each...
another ilegal method like my friend use is using trojan for android..
but carefully using this methods..
