Question Downgrade monthly builds without unlocking bootloader

[SirRhor]

Hello.

I have a bootloader locked Pixel 7 Pro with the April 2023 stock build.
I would like to downgrade to the October or November 2022 build.

Is there any way I can accomplish this?.

Thank you.

EDIT: Got an OTA build, but recovery is saying downgrades are not allowed.
Any other way?

Unless you unlock the bootloader, you cannot downgrade using an OTA. How you tried to flash the full firmware? Why are you trying to downgrade to a firmware that far behind anyways?

Reason, because on Pixel 7 and 7 Pro, firmwares from October and November, deleting an app, you can carrier unlock them, so I am trying to do that. I did it already with a 7 Pro which had the October firmware, obviously, if there is a reset on the phone, it gets locked again, but at least it's something.
I tried using the flashme.bat script, PixelFlasher, used OTA and Full firmwares, Fastboot and Recovery, nothing.

You cannot downgrade to a lower security patch without wiping data. Unlocked bootloader has the same behaviour.

The phone is clean, so no data on it.
