Don't know if the tool can flash it.Can you use the usb tool to flash this rom?
I recommend to not flash the rom and use a microSD card or USB. For around 10 euros you have a 32 or 64 GB and will save lot of time and trouble.
Put it in and you go on custom rom, take it out you are back to MINIX defaut. There is no better option for this in my opinion
