Have just got a used Note 4. Trying to root it using (CF-Auto-Root-trlte-trltexx-smn910f). Cannot get Odin to flash it on the phone.
It seems like the phone somehow blocks flashing. This is what I get after each attempt:
On the phone
SECURE CHECK: FAIL
<ID:0/003> FAIL! (Auth)
<OSM> All threads completed. (succeed 0 / failed 1)
The same happens with any md5 i am trying to flash (TWRP/Philz). Went through all available forums and could not find any solution.
Re-activation lock disabled as never signed in to Samsung.
Has anyone got any ideas on this please
