First of all I want to say that I use BLISS OS x86 7.1.2 system on the mini pc Alfawise X5
then extract a LAUNCHER.apk from the GEMBOX F500 device at this link: https://drive.google.com/file/d/0B1Amj5guHBqaWHpwUm5fTVhSVHM/view
but I can not install it because I have the error "app not installed the package conflicts with an existing package". The problem is that this launcher has never been installed on my device, this error occurs with other applications that were made exclusively for satelite android receivers of my country, already tried to install and the same error occurs, but they were never installed on my device, someone knows the can I do to install LAUNCHERf500.apk ??????
Sorry for my english I'm using google translate, Here are the images of the LauncherF500, who wants to help to download the GEMBOX F500 firmware and extract the apk from the system.
