Thanks! That worked like a charm! Was able to update to the 9-30 image. Hope that takes care of the issue but your symptoms seem quite similar. Will report back after next ota attempt.
Update: the reboot issue us still present, but as described, can turn off and switch to the installed slot for updating firmware. If the phone begins to reboot, place the phone in bootloader mode by holding volume down and power until the screen shows. At that point power down and then power on from off.
Glad to hear at last have a workaround.
FWIW -- I've updated both of my X4s to 1002 and now both reboot without looping. @t3ch42, I'm curious if this new build will resolve your Reboot symptom too.
Hooray and thank you, devs!
