- Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions and then Swipe to Wipe.
- Sideload the LineageOS
- On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
- On the host machine, sideload the package using:
adb sideload filename.zip.Tip: Normally, adb will report
Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report
adb: failed to read command: Success. In some cases it will report
adb: failed to read command: No erroror
adb: failed to read command: Undefined error: 0which is also fine.
(Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.Note: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!
- (Optionally): Root your device by installing LineageOS’ AddonSU, (use the
arm64package) or by using any other method you prefer.
