Does it work and how does this differ for the Deluxe 3 with SD-821?
Yes I have seen the site but try clicking on the download link. It sends you to a website that tells you to "complete 1 of 2 offers" for the download to begin.
Serious spam/malware alert here. I wouldn't run this app with a virtual machine let alone let it loose on my brand new Zenfone 3 Deluxe.
If you actually manage to download this, then a) you don't have any malware protection on your PC (your adblocker should give you all sorts of warnings before allowing you to the "offer" page) and b) you are almost 100% guaranteed to end up with malware on your PC or phone, even if it does manage to root it which it won't because there is no unlocked bootloader yet.
After all that, you will end up with no root on your phone, malware or ransomeware on your PC (and/or your phone) and all sorts of spam in your e-mail inbox.
But of course i'm happy to be proven wrong with screenshots of the phone running a root only app. (nobody should try this though, except maybe if you are going to throw your PC and your zenfone 3 deluxe into an incinerator after you are done whilst using a temporary e-mail address to "sign up" for the "offer")
