Quick question re: root/ta/bl etc on .290 topic




I'll try and keep this short and to the point.
Currently running stock .290 firmware and wanting to root it, preferably without flashing a pre-rooted firmware, and without losing DRM keys.

Now if i want to root it according to this thread, i will need to unlock the Bootloader first:
"You'll have to unlock the bootloader if you want to root the .290 firmware (Android 4.3)."
and then root it via this, before i can run TA Backup to backup my DRM keys

What I'm confused about though, is that once the Bootloader is unlocked I lose my DRM Keys (as per this thread, and many other comments)
"The TA partition contains all your DRM keys for the Bravia/X-Reality Engine.
The first time you mess with your phone by unlocking the bootloader, these DRM keys will be deleted!"


The general consensus with regards to the proper order is:

1. Root
2. TA backup
3. Unlock bootloader

However for .290 it seems to be:

1. Unlock bootloader
2. Root
3. TA backup (if there is even anything left to backup?)

I guess what I'm wondering is if there is anyway to root .290 directly without first unlocking the Bootloader (and thus losing my DRM Keys), and without flashing pre-rooted firmware?
Or do i have this completely wrong, and by unlocking my Bootloader first, I won't lose my DRM Keys (contrary to what the linked thread above says)?

Thanks!
