Hi 😊
This is the ffu files for the abandoned project Astoria for Lumia and resources files.
Clean install stock rim from windows device recovery tool link
Put Lumia in flash mode by power off then hold power and volume down. Open Windows Phone image designer flash stock ffu for Lumia 930/640/XL
Once phone starts, put phone in aeroplane mode. This will stop it from updating while we prepare to disable system updates
Install interop tools
With registry browser go to HKLM ->SYSTEM -> CurrentControlSet -> Services
The default value is 3 change to 4 will stop updates but the store would not work so we need to change it back to 3 and reboot
Use the deployer app to install an apk file.
