I'm having issues trying to downgrade to Andriod 12 from andriod 13 beta 3.

1. I've opted out of Beta
2. Software update notification received
3. Click on download and install
4. After a couple of mins get error message couldn't update 'Installation problem'

The screen remains on the update screen.

What am i doing wrong please help?

Device state: locked

edit:actually now I'm stuck in Fastboot Mode
Phone keeps rebooting back to Fastboot mode

With a locked bootloader, your only option to get fixed is to try sideloading an OTA - usually, the OTA has to be either the same as what you were most recently running or newer. Click the yellow How To Guide quick filter at the top of the list of threads for one of the root guides. Even though you're not rooting, one or two of them should tell how to sideload an OTA - just ignore things that reference root.

This is why the instructions for the Beta program say you should have an unlocked bootloader, as without an unlocked bootloader your choices to fix the situation are much more limited.

You're welcome. Since I never do the OTA process, I always flash the full firmware zip (which you can't do with a locked bootloader), I can't advise any further than what I said about using the quick filter for the How To Guides. At least one or two of these threads should help you, although they may concentrate on doing so with rooting, as long as you ignore the root parts to the OTA method, you can still follow the instructions. You'll get better help to any questions in one of the threads that give OTA sideload instructions:

much appreciated yes want to avoid root or unlocking the bootloader, why does google have it to make it so difficult to downgrade. Maybe take a leaf out of apple's book

To sideload you need USB debugging enabled. Reboot the device to recovery, either by powering off the device and holding power and volume up, let go of power when the phone vibrates, on the the android with an exclamation mark, tap on volume up I think it is. Or by typing in terminal

Code:
fastboot reboot recovery
since it's stuck in fastboot. In recovery tap on 'apply update from adb'

Then download the ota package from here.

Grab the platform tools (Google for it) and unzip it to c:\platform-tools if you're running windows. Open a terminal in the platform tools folder and type

Code:
adb sideload /path_to_ota.zip

Let it do its thing and you should be up and running. I wouldn't try to downgrade from the a13 beta, but you can try. Good luck!

Just a few things. You don't need USB debugging enabled for OTA updates (you can't boot into Android to enable it anyway).

Just be aware that with OTA's, you can't downgrade - only reinstall the same version or upgrade, so you need to make sure you're on Android 13 to reinstall ota version 13 (recovery mode will tell you your version).

Here's a video to help with the ota update.

I don't think I'll be flashing beta version again lol, too much hassle to downgrade.
In the end decided to send in to Google to repair.
I think they will give me a replacement instead of repairing it.

Did anyone notice any major bugs with android 13, can't say I did?

Might seem dumb but I used the web browser tool and flashed back to stock via that from 13 B3 it unlocks bootloader and flashes and re locks bootloader , back on stable 12 working fine then opted out of 13 beta

    Flash.android uses fastboot, which requires the bootloader to be unlocked. User can't unlock it since Android won't boot..
