This will not work.
ZTE has locked EDL access and only people with leaked Auth can connect with Firehose – and currently those are not available / not leaked.
What you uploaded is a Fastboot ROM that ZTE published in early 2025, that is useless because it has MELF (container of ELF programmer files) which doesnt work, because it can not make a Sahara handshake with the device, cant do anything past the "device detected" (via EDL Utility). This ROM is floating around the internet for months now, but you can NOT flash a Z70 Ultra NX733J with it, as QFIL will instantly report a Firehose error.
I get that you wanted to share, but you should know that currently, only people with leaked auth can access EDL, and those are mostly Vietnamese dudes that ask 50USD for it.
