Hello everyone.

Please tell me how to update recovery using terminal or adb? Now I have /e/OS recovery installed, I see that the phone has this option
Settings => Updater => three dots in the right corner => Preferences => Update recovery

And how to do this via terminal and adb?

Do I understand correctly that it should look like this:

 fastboot reboot bootloader

 fastboot devices -l

Of course not,

Logic is right, but you must use heimdall commands, because fastboot won’t work on Samsung devices

something like

heimdall flash --RECOVERY  recovery-e-2.7-s-20250109460371-official-herolte.img --no-reboot
