@Akirainblack: Yup. If you want to be super-safe, just convert it, don't even unpack/rebuild it.
(By which I mean: .bin to .tar.gz [convert] then .tar.gz to .bin [create]).
In this specific case, there's no model/version specific logic, and it already supports the PW, so there's not much risk of doing anything wrong, it's simply copying a file
.
