Of course. Click THIS link,
select country, choose phone model, download upgrade file,
unpack it, and put to root of SDCard, enter phone recovery and make update.

I been search for a week , contact ZTE Support they told me there is no firmware.
Mine case was Z820 MetroPCS.

I Think someone should unlock boot loader 1st then read firmware.

Bootloop issue in most of cases is because update will detect rooted phone and hang on half.

that "rom file" is nothing but some backup files,
totally unusable.

sdcard update looks legit, but is way to small imho.
