What kind of absurdian phone is this? Its been a month now i can't seem to get the firmware for this, there is no way i can unlock a bootloader nor booting into fastboot mode :(

There is no flash file either

any one with good z820 firmware

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.

You can download the firmware :

File Password: dvaldezcelular

sdcard firmware :
https://drive.google.com/file/d/0ByQ...1OZVVxNGM/view

there is no flashtool inside
Firmware still not tested , any one test it ?

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

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