Process to downgrade Mazda Connect Firmware?

[Uuugh]

Hi,

I recently upgraded my 2020 CX-5 firmware from 70.00.335 NA N to 74.00.324A NA N. I didn't realize at the time that the screen resolution changed with v74, and the new resolution is too low for my tastes. I'd like to downgrade to the last v70.

I have a copy of NA N 70.00.367A but I've not found a process to downgrade firmware without using a serial adapter? Although I have Googled and scoured the forum, I've not found a solution.

Is their a process to downgrade? I am able to ssh in using MZD-AIO-TI v2.8.6.

Thanks!

From what I've seen in the past, you're SOL on the downgrade.
