[Q] Upgrade from 5.0.2 (rooted) to 5.1.1 without tripping KNOX possibility?

[Kaito95]

Hello everybody

I want to upgrade to Android 5.1.1 without tripping KNOX. Is there a way to upgrade via FlashFire? I heard that is not possible because the new bootloader has a write protection (only downgrade is not possible anymore).

My current rom is G920FXXU1AOE3 rooted with PingPong-root.
Thanks in advance

You can unroot and upgrade without tripping knox. Although the only working root method for 5.1 is a slightly modified stock kernel (to my knowledge) which in turn will trip your knox. And yes, you're correct, once upgraded to 5.1 you cannot downgrade without special equipment.

I thought so. Hmm what if I try to flash the full stock firmware G920FXXU2BOFJ (DBT) over FlashFire with the EverRoot option and flash the bootloader via Odin?

I can't answer that with certainty but sounds good in theory. Awfully risky shot in the dark though ;(

Unfortunately it doesn't work. I'm stuck now on Android 5.1.1 unrooted ??
A downgrade doesn't work even if I repackaged the firmware file (with 5.1.1 bootloader and 5.0.2 system, kernel and modem etc). It stops while flashing kernel... ?

Well shucks. I'm sure a safe root method is around the corner. Patience is a virtue

For those who failed to root, have a look at this one: https://www.youtube.com/watch?v=5qL9qKbQa54 It helped me rooted my S6 with Android 5.1.1 and Knox is still OK

Your link is broken and i highly doubt it was legit.

There are still no known way to root in 5.1.1 without tripping the knox counter, sorry.
