You do not need to be a hardcore mud to know the importance of starting your S10 in either recovery mode or download mode. In fact, these pre-boot menus are something that everyone should know about. The former can help you get out of soft bricks, while the latter lets you use tools like Odin and Smart Switch to flash firmware files and fix your phone when all other solutions fail.
Just like the S9 and S8 before it, the Galaxy S10e, S10 and S10 + have no physical home button. This means that you need to set the recovery mode or download mode through a combination of Bixby, Volume, and Power buttons. The process is quite simple and easy to master when you know the button combinations for the different modes, which we will highlight below.
Startup in reset mode
To start your S10 in reset mode, you must first turn off the unit. When you have turned it off completely, hold down both the volume up and the Bixby buttons (just below the volume knob), and then and hold down the power button.
Immediately release the power button when your S10 turns on and then release both the volume up and the Bixby buttons when you see the blue screen with the Android logo.
From there, the blue screen will almost instantly give rise to the recovery screen when the device does not detect any commands or updates. Now you can run important tasks ranging from applying updates either via ADB or SD card, wiping the unit's cache or performing factory reset.
To start up your S10 in download mode, you must also turn off the phone to get started. Then hold down the volume button along with the Bixby key just below it, and then hold down the power button.
The phone starts immediately in download mode after that, so release all three buttons when it does. Press the volume up button again to confirm that you want to start the download mode, and you can then browse firmware files or other software with Odin or Smart Switch.
