+        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 flash a custom recovery on your device. Press 'Confirm and run' to start the process. Confirm afterwards to continue.
+      command: heimdall_flash_recovery
+    - type: confirm_button

+        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 & release the buttons immediately when it does, then boot to recovery with the device powered off, 
+        hold *Volume Up* + *Home* + *Power button*.
