Bummer on the RMA, sorry excuse they gave, but they are known for making reasons up to deny. At least they didn't smash it and say you did in shipping, or bend your CPU socket pins and say you did that too.
So you have system back and programmer now, or just programmer and waiting on system?
*Edit, just found your PM -
Here is package with driver and several versions of the software, sometimes you need to try a few until you can get good verified backup from your main system (Any system, all are different)

if your laptop BIOS is W25Q64FV you may need to use CHIP ID W25Q64BV, or visa versa. I mention this because this is a common used chip and this is what I've found regarding that exact chip
Once you can get a verified backup of your Asus, open it in hex and make sure it's not all blank (FF), if it is that's not valid, try again with another version of the software or different chip ID. I always start with latest, or at least 1.30 (Don't like the layout of 1.31
)
Once you get a good backup, send here so I can pull out your details (hopefully), then we can put back in another BIOS for you later. To get back up and running, program in the BIOS I posted in post #20 (.rom)
