Also known as Odin Mode, the Galaxy S6 download mode is required if you want to manually flash a firmware onto your device. Since we talk a lot about customization, let’s talk about how this is done.
Samsung includes this download mode/odin mode on their smartphones and tablets as a way for their technicians to repair it. It’s also there for customers who know about it to flash an official firmware onto their device. Even if it isn’t there for their customers, thanks to download mode and the Odin program, we can.
Doing this, assuming you flash an official firmware, will not void your warranty either. So just make sure you have an official firmware downloaded before you flash it(I recommend getting these from SamMobile).
Getting into download mode and flashing Samsung firmware images allows us to do a lot of different things. The most basic thing is that it allows us to re-flash the firmware we are currently on. Some might want to do this instead of doing a factory reset, others might need this in case downloading the update failed or became corrupt. This also allows us to downgrade from one version of Android to another. Not everyone wants to latest version of the software and thankfully we have this option. Lastly, this allows you to flash an OTA update without waiting it to be pushed to your device.
So please remember, download mode(and Odin) can let us do some extremely powerful things to our smartphones and tablets. If something bad happens, or if you select the wrong option during this process, then things can go south pretty fast. Please be sure to follow the guides here(or posted on reputable websites) before you dive into download mode. This also lets us recover from a customization that messed up badly. While doing a hard reset like this isn’t the ideal option, it’s much better than having a bricked Galaxy S6.
Galaxy S6 Download Mode
- Power Down the Galaxy S6
- Press and Hold the Home Button, Power Button and Volume Down Buttons at the Same Time
- Continue Holding These Buttons Until You See a Special Download Mode Menu
- Once You See that Download Mode Menu, Immediately Let Go of Those Buttons
- You’ll Need to Press the Volume Up Button to Accept the Warning
As with most special boot modes for Android, you’ll need to start this one by powering down the Samsung Galaxy S6. Once the device is in a powered off state, press the following buttons down at the same time – Home, Power and Volume Down. You’ll want to continue holding these three buttons down until you see a special Download/Odin Mode menu appear. Once you see this menu then you should immediately let go of all three buttons. This process can take you a time or three before you get the hang of it.
If you see that you are booting up into the regular Android OS then simply wait for the boot to finish so you can power the Galaxy S6 down and try again. When you properly boot up into the Galaxy S6’s download mode, you’ll most likely see a warning message that tells you about a custom OS. You can flash a custom OS with odin and this is just a warning. As long as you flash an official firmware here, you shouldn’t run into any issues. Once you dismiss the message, then you will be taken directly into the full download mode menu and this is where you would connect the Galaxy S6 to the computer that is running Odin.
Note – To get out of the Galaxy S6 Download Mode, you’ll need to press and hold the Power button and the Volume Down button at the same time.
I will be sure to include tutorials later that require download mode. These tutorials include how to downgrade the Galaxy S6, how to revert back to stock, etc. As always, if you have a question or if you get stuck on this tutorial then please leave a comment at the bottom of this article and I will help out in any way that I can.
