I recently got another zte grand x max + cant update software manually says signature error?

the process gets aborted every time and I have successfully done it from the offical link on zte before but I can not get it to work on this phone, doing the sd card update.zip

    hi, I do not see this particular phone has an update file available so you can do the update via sdcard. So the only option to have software update would be via OTA. Have you tried to run the manual update on the phone (typically under setting, system update (or about, system update)).
