asus loves to put GPIO enables ont their boards to control flash writes. 
My guess is you are getting no write cycles to the flash part.

This is pretty easy to probe for, find the GPIO registers and starting 
changing them one at a time, and see if at some point you have flash 
writes working. Some of them, when changed, may reset the board ... so be 
prepared for that.
