How to update Android version in command line?

[Gquirt]

I’ve been putting off the upgrade to Android 13 for far too long. I’m honestly not sure the best way to go about it. Others have mentioned just doing the installation steps again, but there are definitely parts of it that won’t need doing again, like unlocking the bootloader. Even just a “do x, y, and z headings in the install instructions” would be super helpful.

My phone is a Asus Zenfone 8 if that makes a difference. Here’s a link to that install guide if it’s needed for reference.

I did find this seemingly easier guide from LineageOS that seems intriguing. I’d just give it a shot, but I’ve heard too many stories about bricked phones for me to feel comfortable just poking around.

If the device already run an older version of /e/OS,

Dirty upgrade to /e/OS-T is possible ! (But not for all devices)

The official documentation seems not accurate (inherited from previous versions), since the /e/OS-“T” build generation (like LineageOS 21) are expected to include the updated needed parts of the firmware. finally the sentence : “your device must be on latest android” (that leads in many case to lose /data by reinstalling full stock software ) now looks not mandatory, at minus on a device already running /e/OS “R” or “S” version. . @Leon If you reread attentively their post, none of them ha…

Thank you! I will give this a try.

Is this a guaranteed wipe of my device’s drive or will it only wipe if something goes wrong?

The long-tapping and copying to clipboard feature may only be available from Android 10 (q) on.

After getting distracted figuring out a good long-term backup solution, I finally tried updating today.

Two weird issues I ran into:

1. My Arch Linux machine couldn’t see the device through ADB when it was in recovery mode. When I tried again on a Debian system, it could see the device. No idea why this would be.
2. I had to run the ADB daemon as root to actually flash the image.

Now I’m up and running with /e/OS 2.4 and Android 13. Thanks for the help!
