Video Description
~~~~~~~~~~~~~~~~~
Android 13 Beta 1 wasn’t the only big release announced this week. We also saw the official release of LineageOS 19 which is currently based on Android 12L (aka Android 12.1)

If you’re running an official version of LineageOS 18.1 on your smartphone or tablet and it has been transitioned to version 19, then you’ll notice the built-in updater is no longer working. The devs behind the ROM coded the updater this way because it can’t switch between two major versions of Android.

Instead, we need to manually sideload this update if you want to go from an official version of LineageOS 18.1 to the newly released version 19. And in this video I’m going to show you how this upgrade is done without losing any of your personal data.

This video will walk you through updating your phone from LineageOS 18.1 to the newly released LineageOS 19 using the official upgrade path. This means we’re using LineageOS recovery in this example, but other custom recoveries like TWRP are likely going to work as well.

There are some things we need to have set up ahead of time, though.

For example:
We need to go ahead and download the LineageOS 19 firmware that is built for your device.
We also need to download a Google Apps package for Android 12 that also matches your CPU architecture. For most of us that will be ARM64
And finally, you’ll want to download any other addons (such as Magisk) that you want to install on the device.

These files need to be downloaded and stored in the same folder as your ADB and Fastboot tools.

When you’re ready, let’s go ahead and boot the Lineage 18.1 device into Recovery Mode and connect it to the PC with a USB cable.

You likely will not find an unofficial build that has an upgrade path to the newest official version that will preserve the user data.
