    Dear Scott,

    - we talking about Samsung firmware or about Qualcomm firmware?
    - what part of firmware most important for root or we need just complete firmware?

    please more details


    Exynos models are typically able to be bl unlocked

    Snapdragon chinese or latin america devices are typically able to be bl unlocked

    Snapdragon usa models aka U U1 W or carrier specific models are not able to be bl unlocked and need exploits to root which has become difficult since s9 models (although i released extreme syndicate root for usa variants of s9 s9+ and n9)

    I tried various things on g975u and n976v with no luck in rooting even on combo firmware or edl.. I only managed to elevate to system privs..

    Is it impossible, no. is it difficult, yes. Until exploits can be found then it will not be rooted.

    If anyone doesnt know, I have been researching samsung security for a few years now. I was worlds first rooted S8/S8+ as well as worlds first rooting s9 s9+ n9 all usa variants and various exploits I found during my research.

    All exploits have been patched with each device release i.e. 8 devices exploits dont work (to an extent) on 9 devices and 9 exploits didnt work on 10 devices so i cant imagine any of my 9 exploits working on 20 devices.
