Interesting. I just did this update on one of my Pro 1x phones, and it worked fine.
I did it the usual way that I do to avoid losing root, ie. wait for the update process to require reboot, then open Magisk, select install to vacant slot, then reboot.
All working tickety boo now, version 23.2-20260209-NIGHTLY-pro1x
Of course LTE reception remains unusably bad, but that kinda goes without saying now.
I guess I should wait for the next update for my other 1x.
