Upgrade LineageOS on
Google Nexus 7 2013 (Wi-Fi, Repartitioned)

Basic requirements

1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
2. You actually want to upgrade your device to the newest version - if you wish to downgrade to an earlier version of LineageOS, follow your device’s instructions for installing LineageOS the first time.

Manually upgrading LineageOS

The updater app does not support upgrades from one version of LineageOS to another, and will block installation to any update for a different version. Upgrading manually requires similar steps to installing LineageOS for the first time.

1. Verify your device is using the latest Lineage Recovery. Simply download the latest recovery file, named recovery.img. Follow your device’s installation guide to see how you can update your recovery image.
   warning

   Important: These instructions may not work if you choose to use a different recovery!
2. Download the LineageOS install package that you’d like to install or build the package yourself.
3. Make sure your computer has working adb. Setup instructions can be found here.
4. Enable USB debugging on your device.
5. Reboot into recovery by running adb -d reboot recovery, or by performing the following:
   • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
6. Wipe your data partition (this is usually named “Wipe”, “Format”, or “Factory reset”)
   warning

   Warning: Without this step your device will not boot on the new version!
   warning

   Warning: This step will wipe your personal data and remove any user-installed apps. If these are important to you, then you should back them up before performing the upgrade.
7. Click Advanced, then Enable ADB.
8. Run adb -d reboot sideload.
   warning

   Important: The device may reboot to a blank black screen, fear not, this is a known bug on some recoveries, proceed with the instructions.
9. Run adb -d sideload /path/to/zip (inserting the path to your LineageOS package).
   check

   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 error or adb: failed to read command: Undefined error: 0 which is also fine.

10. (Optionally): If you want to install any add-ons, click Apply Update, then Apply from ADB, then adb -d sideload /path/to/zip those packages in sequence.

    info_outline

    Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
11. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
