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.
