hi, when i went to download it again to show you the name, i realized i had a new update .. so i downloaded and updated the X8 sandbox F1 VM, now with this new update i managed to install the modified google play without problems, this working! sorry for the inconvenience xDI thought you used VMOS
Modded Play Store probably not supported on F1/X8 sandbox
Use VMOS or VMOS Pro with custom rom
