So I've got myself a Sony Xperia Z1 and I'm a little unsure about how you root it.
From my understanding you need root to backup the DRM keys. but to get root apparently I need to unlock the bootloader to be able to put a certain version of the ROM on (which wipes the DRM keys).
Then I can root the phone.

I'm seeing a loop here and I'm not sure what the first step would be. if anyone could point me in the right direction it would be heavily appreciated.
