Desktop (please complete the following information):

• OS: Linux Mint Cinnamon
• Version: 21.2

Smartphone (please complete the following information):

• Device: Samsung Galaxy S10 / codename: beyond1lte / model: SM-G973F/DS
• OS: Original Stock Samsung ROM installed is Android 12:
• Version A12 AP/PDA: G973FXXSGHWC1 (PDA) CSC: G973FOXJGHVJ4 CP: G973FXXSGHWB3 (BaseBand)

Additional context It seems that the command adb reboot download does not show the expected unlock bootloader option I did some test and was not able to get the right screen using adb. It seems that on Samsung devices (at least S10), you really need to that manually to get the option to unlock the bootloader: "With the device powered off - hold Volume Down + Bixby and connect USB cable to PC"
