I use a linux live CD based cloning (clonezilla) program on all notebooks and desktops/towers (work and home) regardless of OS and it has rewritten perfect images flawlessly. My background is not in coding, more electronics and mechanical - this said, I am able to hack the command line, just not real familiar with. Seems I recall dd being the linux embedded imageing, would the above formula rewrite the image to the tablet? Or isn't there some reason the flasher program is used due to the way the hardware actually stores AND interacts with the code? I tend to view these a bit differently when I haven't built up from parts, what my OS is going on/in.

I run my OS off the SD card as described in the thread "Cloning OS to SD/MMC Card: Simplified instructions" then I take the SD card put it in a reader and make a copy of it. While I haven't had to use it something like should restore it on the card. This is a modification from here.
