Running Android Pie right out of the box, similar to other Samsung phones, Galaxy S10 series also comes with a built-in download mode. If you are coming from an iPhone previously or a non-Samsung device, basically this mode is used to update and modify system firmware. It comes quite in handy when the phone is stuck in a boot loop, has a custom ROM installed or needs to be updated manually. Seeing how the mode directly effects the functioning of the phone, Samsung has hidden away direct access to it, avoiding accidents.

If you follow one of our official update guides to update with Odin, your warranty would not be voided neither would you trip Knox — Samsung’s security solution. To make it easier to understand, we have broken down the complete process into simple steps right ahead. Follow them to access download mode on Samsung Galaxy S10, Galaxy S10+ and Galaxy S10e.

Enter Download Mode, Samsung Galaxy S10

What is Download Mode / Odin Mode?

Galaxy S10 ships from Samsung with an unlocked bootloader from the factory which is quite different from other manufacturers who ship their smartphones and tablets with a locked up bootloader. This is also one reason why Samsung phones receive the highest amount of custom mod packages as it is very easy for any customer to use Odin on their PC along with their newest Samsung Galaxy smartphone – in this case, the Galaxy S10.

Odin is an internal tool at Samsung that allows them to flash various firmware and files on to the Samsung phones and tablets. There are many releases of Odin available online, and you can download them all here. After the phone is connected to your PC in Download Mode, Odin will detect the device and if the connection is successful, it will set up a communication port between the phone and the computer. That will allow you to flash different packages on the Samsung Galaxy S10.

A word of caution, do not mess around with Odin while in the Download Mode of your phone. It can cause serious damage to your device, beyond repair. And not to forget, anything you do in Download Mode is not covered in your official Samsung device warranty. Therefore, we recommend you use a specific guide or a detailed tutorial rather than experimenting on your own. You can find a really good guide on our website.

You can also use Odin to downgrade your Galaxy S10 from a specific Android release or build number to another one. This comes in handy when a newer firmware causes slow downs, long boots or even crashes.

Just by accessing the Download Mode, you will not lose your warranty by Samsung. However, if you flash custom files like a ROM or root package which Samsung doesn’t officially intend, your warranty will be void. These custom files are generally those which are created by third-party developers and are not signed by Samsung. We think this is the only downside once you try to customize your phone through Download Mode and we also warn of this in every post we cover.
