Sorry for my poor English, but I don't speak it very well...
I bought FPSE from Google Play and it works without problem on my device (a chinese console called JXD s5110).
After some days I flash a new official stock rom (upgrading from Android 2.3.4 to Android 4.0.3) now I can't install FPSE because Google says it's incompatible with my device.
I tried to edit build.prop file to mimic some other device but for Google fpse still incompatible, so I can't download it from market.
Any solution?
