No, no root or unlock. Just a stock device. I did disable some apps, but nothing of importance.
Oh, and i have the 8gb ram version of the t860 tablet.
Tried proxying through germany, didnt help. Still on September patch
You can now flash the january 2021 security update with PC Odin and selecting the HOME_CSC so it shouldn't change your CSC.
I downloaded the German version (DBT) and I flashed it on my french tab S6 (XEF) and it works fine.
On the other side, I bought a 512 GB Galaxy Note 9 from Hong-Kong but this phone came from Telstra (Australia) so I changed the CSC to XEF to be sure I have no trouble...
