This is the most recent update I can find, it is the file HE_FULL_UPDATE_13-32-14.00-TG-U07-STD-HEL-04 dot zip It says TC77, but the TC52 and 77 files are the same.  According to Zebra anyway, the filename for both models are the same files..   https://xdaforums.com/t/zebra-tc57-os-update.4699809/   ...
