ZTE Handset software update tool error
Good luck on your attempts to brick your phone permanently, i am sure you will succeed eventually.
To brick it using QPST you can use the first 512bytes from the partition.hex from the update1 folder downloaded with the actual tool that can help you fix your phone. Just use that and qpst and you can just put random files in the rest of the fields and it will brick permanently. It's an easy fix for the ultimately stupid who do their very best to brick their phones but fail even at that.
if that is not what you want to do, go back to aleksanders post and do it properly.
If it really doesn't work after following the instructions exactly and having the right drivers installed then we need some information.
1. exact version number of your windows installation
2. exact serial number of your phone
3. exact driver you have installed and that includes what is reported in device manager
A screenshot where everything of value is covered by some window without any information is nice though, should just maximize it and post that, that would be MOST helpful. If you cannot maximize it then perhaps using black spray paint all over your monitor and taking a picture of it would be a solution?
I do like the ZTE handset update for a completely different phone though, good on you, that might have bricked it for good but you were unlucky and failed with that since it doesn't recognize it as a supported phone (mostly because it's not).
If you are still persistent on actually killing the phone permanently after reading this i suggest a sledge hammer, it will definitely work and it's less work to boot.
What you really should do is pack it up in it's original packaging, return it to wherever you bought it and demand no refund, you are simply too stupid to have a phone.
