Upgrade Instructions - BiTGApps/BiTGApps Wiki
Whatever BiTGApps package you have installed, when installing for the first time. The same set of packages you need to install, when upgrading from previous release. Keep in mind, if you have used BiTGApps config before, it should be there when you upgrade.
Warning: With R37 revision and later releases, you must have everything from last BiTGApps install in your device for successful upgrade. Any component of BiTGApps wiped or lost from system will trigger abort function and break installation.
- The above scenario is also applied to microG package
