Downgrade after upgrading to Android 6 - knox tripping? G900F

Hello!

Sadly my G5 ist broken and I have to send it to a reprair center.
The center has the habit to upgrade any phone they receive to the newest firmware

My G5 was delivered with Lollipop - I downgraded to 4 to use Towelroot.

So my question - if they force me to Android 6, is it possible to downgrade without tripping knox?

It's a G900F btw :)

Thanks in advance!

Best Greetings!

Please Help Me Root My Samsung S7 Edge SM-G935F Exynos WITHOUT Tripping Knox

Hi,

I just needed a bit of advice/help. I've just bought a new Samsung S7 Edge SM-G935F Exynos and i was reading this thread and i wanted to know how i could root my phone version without tripping the Knox counter and without invalidating my warranty?

I would really appreciate any help as I'm new to the android scene and have just moved from ios.

Thanks in advance.

Rooting S6 w/o tripping Knox to Debloat? S6 Marshmallow 6.0.1

title says it all, I have just bought my S6 and out of the box it's 6.0.1, would it be possible to root it, uninstall unnecessary apps and then unroot it without tripping KNOX in the process?
