Prompt [Q] Need a little help

Hi guys, I apologize if I'm asking in the wrong place, it's just that xda is big and I couldn't pinpoint where I should direct myself, and if I'm in the right place then "uhhh... that's a relief!"

Anywho.. I have a ZTE Mimosa X Android phone and it seems to be stuck in APX mode, turning it off doesn't work it won't enter into any mode and the only way to know that it's alive is to plug it in to the pc which will detect it in APX mode.

I searched around a lot but couldn't find a decent helping section or anything all i found was that I'm supposed to use nvflash and that's it.
If someone can be so kind as to direct me the right way I'd appreciate it very much...

Thank you in advance.
