Anyone had success making a bootable USB from Sierra InstallESD.dmg?

I'm trying to make a bootable USB on Fedora. I downloaded the installer app from the app store and copied InstallESD.dmg to my flash drive. I can't use UniBeast to create the installer as I don't have access to my iMac anymore (it's at my parents house inter-state). I tried using TeamViewer, and then using UniBeast, dumping the contents of the USB to a disk image and sending that to myself but I wasn't able to boot from it.

So back to the InstallESD.dmg method, I verified the checksum with sha1sum to ensure it's valid, and used: sudo dmg2img -v -i InstallESD.dmg -o /dev/sdc to copy its contents to my USB.

This Success fully writes to the disk: http://i.imgur.com/69o7OC2.png but that being said my friend showed me a screenshot of his USB after using UniBeast on his mac and it looks different. So I guess it's not correct.

I really don't want to download a macOS installer from whatever source, since I want to make sure that the OS I have installed on my system is clean - and I already know that the InstallESD.dmg I have is clean as it's from the app store, and I know it's valid as I've compared its checksum with known checksums.

So, has anyone been able to make a bootable installer from InstallESD.dmg alone?

Thanks.

(P.S. I already have Clover on my main EFI partition on my internal HDD.)
