I tried to enter Download Mode on my Galaxy S23 5G (S911U), but it popped up in a turquoise menu with the message "Reboot device [D144]" to flash the S911U1 firmware (unlocked). I want to get rid of the carrier-specific junk and properly select languages ​​because most Samsung apps and QS are in English.

Can anyone explain why this is happening or help me get into Download Mode?
