+        As a first step, you need to boot into the bootloader. A bootloader is the piece of software, 
+        that tells your phone who to start and run an operating system (like Android). Your device should be turned on. 
+        Then press 'Confirm and run' to reboot into the bootloader. Continue once it's done.
+      command: adb_reboot_download
+    - type: call_button
+      content: In this step, you need to boot a custom recovery on your device. Press 'Confirm and run' to start the process. Confirm afterwards to continue.

+        Unplug the USB cable from your device. Then manually reboot into recovery by pressing the *Volume Down* + *Power buttons* for 8~10 seconds 
+        until the screen turns black to reboot  & release the buttons immediately when it does, then immediately hold *Volume Up* + *Bixby* + *Power button* until you are in recovery mode.
