The Android robot error screen comes from the stock recovery (the one from ASUS). Possible explanation would be that you booted into the ASUS stock ROM after installing TWRP. In that case it might overwrite the recovery partition again. Boot into TWRP directly after flashing and while you're at it get rid of the ASUS mess.
