tar.gz ROM Source Code: How to use?

[Guest tooplanx]

On the Huawei EMUI 3 website they offer the source code for their latest software for my phone. It is in a 'kernel.tar.gz' format.

Can this be used in any shape or form to update my phone to this latest software? And if so how?

I've read vague bits about extracting it as zip and then applying through fastboot...?

My phone is currently stock, unrooted, bootloader locked. (Huawei G535)

Many thanks.
