This is our guide on how you can enter the Samsung Galaxy Note 9 download mode on this phone. Just as many other Android smartphones come with a stock bootloader, Samsung devices ship with a similar download mode. For maintenance purposes, this specific mode of the phone is designed to give access to system partitions which are otherwise read-only during normal usage. In simpler terms, through download mode, you can use a computer and Odin tool to flash firmwares, ROMs, root and other system packages on your Galaxy Note 9. To access download mode, you need to execute a unique procedure which have listed in our guide ahead.
Samsung has been quite open to Android enthusiasts. Rather than requiring a bootloader unlock, all Galaxy smartphones have the download mode built-in which can easily be used to flash system packages. However, as this mode has control over the core running of the smartphone, it is hidden from normal use. To enter download mode, users would need to perform a certain button press combination. Now, before we proceed, it is also important to note that if you flash a custom file through this mode, your phone’s Knox security would be tripped hence voiding warranty but if you flash an official firmware, there would be no issue.
What is Download Mode / Odin Mode?
Galaxy Note 9 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 Note 9.
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 Note 9.
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 Note 9 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.
