[Q] Xperia Z2 Locked Bootloader Info topic

I have an Xperia Z2 with a locked bootloader. Will these methods for rooting and backing up data work with a locked bootloader?
Root method: http://forum.xda-developers.com/show....php?t=2784900
DRM Backup tool: http://forum.xda-developers.com/show....php?t=2292598
If not, you you please provide me with links to methods that work.
Thanks.
