also found this, looks to be a later life update release for android 13..http://support.eglo.com/downloads/Scannerupdates/

found this looking for my own tc52, it has the latest android 11 rom, and the android 13 rom.. though I would love to find the Android 14 rom..https://archive.org/download/zebra-firmware/Zebra%20Mobile%20Computer/TC52%20Firmware/
