This sub-menu that all Samsung-manufactured devices have, the Download Mode on Galaxy S9 and Galaxy S9 Plus. The process itself is simple and fast, though it will take up some of your battery, which is why you must have it charged at a minimum of 50% before anything else.
Also notably, if you simply access the Samsung Galaxy S9 and Galaxy S9 Plus Download Mode for installing some Android updates manually (of course, with the Odin app), or to install who knows what custom recovery, your phone’s warranty should be just fine. On the other hand, if you root the device, flash custom files, or do anything else that Samsung wouldn’t really want you to do, you can be sure that the warranty will be lost!
Knowing all these, if you still want to get to it, let us show you how to do it. Like we said, it should be fast, as in taking you only a couple of minutes. If you can’t get to it, you probably don’t have this mode available on your version of Samsung Galaxy S9. But don’t just assume that, try it out!
In order to enter Download Mode on Samsung Galaxy S9 and Galaxy S9 Plus…
- You can either use a special combination of keys for booting into the Maintenance Boot Mode;
- OR you can use a third-party app from the Play Store, like the ROM Manager (you can also get it from this link) or something similar.
Now, if you’re not familiarized with terms like CWM, TWRP or any other custom recovery tool, you will most likely want to try the first option before anything else. Speaking of which, you can enter the Download Mode by taking the following steps:
- Tap and hold the Power button on the device until you bring up the menu with the Power off option;
- Select it and wait for the device to shut down completely;
- Then, you can tap and hold the Power and the Volume Down buttons, at the same time, for a few seconds or so;
- You’ll see the first Samsung boot screen loading on the display and you must keep holding the two buttons;
- After that, the screen will turn black once again and, finally, enter the Maintenance Boot Mode;
- At this stage, you can release all buttons and begin exploring your options with the Volume keys – the Volume Up and Volume Down keys will let you jump from one menu to another;
- For starting or initiating a process that you just highlighted from the Volume key, suffices to hit the Power button.
When you’re ready to return to the normal mode, you will have to navigate to the option labeled as Reboot (again, from the Volume keys) and briefly press the Power key. In case you can’t seem to leave the Download Mode, you might want to long press the Power button, for around 10 seconds and that should do it!
Back to your other option, assuming you are a knowledgeable user of custom recovery tools and you’ve worked with TWRP or CWM before, you can probably anticipate the drill…
The above-mentioned ROM Manager is waiting for you in the Play Store. Get its software, install it, and start using this app to flash your recovery to the most recent ClockworkMod recovery version, if needed. Or, if you prefer, you can run some backups and restores on your Android, when you’re looking for a major software cleanup. You can even install ROMs from the SD card if you want, without ignoring the over the air option either!
The point is that you can do plenty of cool things with the ROM Manager, as long as you know how to use it. And entering the Download Mode on Samsung Galaxy S9 and Galaxy S9 Plus shouldn’t be difficult either!
