microG

LineageOS R Mod v308

• In order to get microG working proper we need to enable signature spoofing.
• Follow this guide to enable signature spoofing - LINK
• After you get signature spoofing enabled follow the same instructions for Android 10.1/LineageOS 17.1.

Android 10.1/LineageOS 17.1

• To get microG working properly (Must have Magisk/Root completely installed and android debugging (ADB) enabled with rooted debugging enabled.
• Installed microG onto Unofficial Lineage OS GSI 20200920. Follow official microG installation instructions from their page plus minor changes listed below.
• Connect phone to PC and open a console/terminal and run: $ adb shell
• Then Get su permissions: $ su
• Grant SU permission to the shell and run this to give permission to the FakeStore/BlackStore: # pm grant com.android.vending android.permission.FAKE_PACKAGE_SIGNATURE
• Reboot.

LineageOS 18.1

• It is mentioned that signature spoofing is enabled in Andy Yan's builds of LineageOS 18.1 however I have not tested this.
• If it is the case that signature spoofing is enabled then follow the same instructions for Android 10.1/LineageOS 17.1 to install microG
