Bootloader looks like its from a phone 20 years older. Odin does not recognize the phone in BL mode. I am using snapdragon. Any ideas? are there new drivers?

Edit: I had to boot back in to android and remove google account, then regular BL showed up. Unlike previous phones, u cant boot to bootloader without removing google account first.

Flash via ODIN is successfully but CSC does not change

So i am trying to change the CSC of my Galaxy note 20 ultra from DTM to DBT or VD2 ... all of them are a part of OXM multi CSC firmware.
Flashed via ODIN using the right CSC file, and the flash was successful however the CSC did not change ... Tried multiple times and ended up with the same outcome.

Any one else in the same situation?

The same happened me with SFR phone and trying to flash from SFR to XEF firmware

I can imagine, that T-Mobile Germany (DTM) has "locked" somehow for changing CSC to the UN-branded DBT one (which I can understand they are doing this)

Just got an update in France (Orange): N986BXXU1ATH3_N986BOXM1ATH7_FTM , talks about stability updates in the release notes, would really like to get Call Recording and Samsung Blockchain working : Google Drive Link for DL -> https://drive.google.com/file/d/1omILkloFOYgm0gqyjIRwKlcvjySuBFkB/view?usp=sharing

Also, first flash failed, switched to Samsung USB cable which came with the phone and it flashed with no issue.
