Stuck in bootloop after latest update

Gidday
To say I am a pissed off ASUS customer is an understatement...only just got my Zenfone 2 back a couple of weeks ago after getting the motherboard replaced as the camera was stuffed...and now today after applying an update the phone got stuck in a boot loop and I cant for the life of me get it back working again...

Can anyone point me in the direction to the steps to recovering the phone via sideloading the original firmware? I am able to access recovery mode and have attempted to re-install the firmware using the ASUS flash tool but I keep getting the error message that the serial number is incorrect,

cheers
