For when people need to reflash, mostly it is annoying as I am testing to switch urls to my localhost as well

We should make sure we have the latest zip though: if people are selecting a nightly, I suspect they expect to re-download and overwrite?

E-Tag might be enough, or we add some cheksum ?

Yup, I dont think its super crucial, it was mostly for me when I kept reflashing the same image. 

I cant seem to do a HEAD requests though

    $ curl -X HEAD https://index.taskcluster.net/v1/task/gecko.v1.mozilla-central.latest.linux.aries-eng.opt/artifacts/public/build/aries.blobfree-dist.zip

so may be more effort than its worth

Looks like we can do something in fact. I suggest that we:
 - check if in b2g installer directory we have a file name matching the one from the build url
 - if so, compute MD5
 - send that with proper headers in XHR
