UE43KU6079 T-JZL6DEUC-1260.1 downgrade to 1169.2 possible?

[Ziladus]

Hi,

I have a Samsung UE43KU6079 with firmware T-JZL6DEUC-1260.1.
Sub-Micom: T-JZMDEUS-1007.

I would like to downgrade to 1169.2 to use K-root/SamyGO if possible.

I found reports about downgrade from 1260.x, but most seem to be for T-JZMDEUC.
Can anyone confirm if downgrade is possible on T-JZL6DEUC-1260.1?
Is there a safe method, or should I not try it?

Thanks.
