1. dont flash the latest 4.3 yet
2. downgrade to 4.2 and root using doomlord method or root by bin4ry method
3. once rooted, backup TA partition
4. flash latest 4.3 via sus, pcc, or ftf
5. unlock bootloader
6. flash custom kernel with recovery
7. boot to recovery, flash supersu update zip
8. reflash original 4.3 kernel
9. restore backup TA
10. enjoy 4.3, root, locked bootloader with intact drm keys!

To Flash only the kernel from the new rom,
In the flashing options, exclude all (right box) except Kernel.

Yes, root works like a charm but you need to unlock bootloader and flash advanced stock kernel from .256 leak cuz it have recovery and flash the file from attachment, then you must revert to stock kernel and lock bootloader. Voila!

I can't unlock bootloader ;) Orange locks bootloader and anyone can unlock. Then I am looking for method without unlocked BL. And I want to flash kernel from JB 1.257, root and reflash kernel from 4.3. But I'm not sure it is safe.

please don't try that !! it's not possible to use 4.1.2 kernel on 4.3 , it may brick your device .

Hi, I just root 266 by unlocking bootloader, flashing Advance Kernel and updating SuperSu via CWM, now the question is should I flash the 266 stock kernel? and why?

Thanks

    Can anybode write the steps for rooting new 4.3 on unlocked bootloader ???

    It would be the same...

    However you can also flash Doomlord's 4.3 kernel, then boot to recovery and flash the super su zip for root. The kernel from the leaked 4.3 rom seems to be the same as the kernel from the latest update.
