Whoa.. The AT&T Galaxy S7 and S7 Edge can now have root access. What seemed unimaginable for ever has finally been made possible, thanks to br3w3r over at xda.

The AT&T S7 and S7 Edge root is made possible with an engineering bootloader, which, if you do not know, is not meant for the end users of Samsung devices.

An engineering bootloader is probably (strictly) meant only for Samsung employees involved in software team at Samsung, and why it allows you get root access is because it’s not fully locked as it’s used for engineering purposes.

You can get the AT&T S7 and S7 Edge engineering bootloader from the download link below. Also, flashing an engineering boot requires a special version of Odin that can bypass SHA-256 (something that blocks installation of engineering bootloaders), so download that too along with other files provided below.
