You need to enter and use recovery mode on your Samsung Galaxy S9+ but you don’t know how? Or maybe you just want to learn more about this dedicated environment which can be accessed and used on your smartphone. Well, either way, we’ve got you covered: during the guidelines available below we will review the recovery mode menu along with the methods that can be used for bringing this mode on your Galaxy S9 Plus.

So, shortly, among this step by step guide we will try to define the recovery mode environment, we will review the advantages of using recovery mode, we will also talk about the risks that can be implied, we will mention the differences between stock and custom recovery platforms, we will mention the essential pre-requisites that must be followed before using this particular mode and we will eventually detail the steps that must be applied in order to complete the reboot process.

Yes, a reboot sequence must be completed for accessing recovery mode on the Samsung Galaxy S9 because this mode cannot be reached through built-in settings. Moreover, it is hidden by default since it cannot run simultaneously with the Android Mode, thus, when recovery mode will be running the Android mode will be disabled.

In that matter, we can mention our first conclusions: recovery mode is a dedicated environment, pre-loaded on your Samsung Galaxy S9+ and which can be accessed only in special ways because it runs independently from the Android mode. Now, through recovery you can ‘communicate’ with your phone’s internal system, meaning that this mode can help you customize, optimize, personalize, update, tweak and repair the Android OS that powers your smartphone.

By default, your Galaxy S9+ comes packed with the stock recovery environment. Through this mode you can initiate only official operations because factory restrictions are featured – so, in that case we can only talk about supported processes such as making a hard reset, clearing app data cache, or manually applying OTAs.

On the other hand, the stock recovery can be replaced with TWRP or CWM recovery, which are custom environments. Through a custom recovery image you can perform different other operations as you won’t have to deal with factory restrictions anymore. In that respect, if you are using a custom recovery platform, note that you can already choose to gain root access, remove bloatware, add custom apps from other sources than Google Play, install custom MODs, ROMs and kernels, overclock or undervolt CPU frequencies and lot more.

For now, one thing is extremely important for us: both stock and custom recovery images can be entered and used in the same way – by using the methods explained below. Moreover, going into recovery won’t trip Samsung KNOX so you don’t have to worry about losing your phone’s warranty or the access to built-in apps - putting your Galaxy S9+ into recovery is an official process supported by your OEM.

Also, the steps from below are helpful even if your device was already tweaked – going into recovery can be done in the same way whether we discuss about rooted systems, about unlocked bootloaders or about custom ROMs.

Now, if you plan to use this dedicated environment for initiating tweaks, the best will be to charge your Samsung Galaxy S9+ before doing anything else – certain custom operations might wipe everything from your phone. So, without thinking twice you should use backup and restore devices in order to save your contacts, call logs, texts, EFS folder, internet settings, calendar info, images, videos, audio files, IMEI / NVRAM data and similar other packages. A general backup operation can be usually performed without hassle as you can use different built-in cloud storage solutions and you can even sync some files with your Google Account. Additionally, a backup can be applied through third party backup and restore apps available on Google Play – in that case just make sure you download already tested platforms.

Before starting the steps explained below I recommend you to check the power that’s left on your handset. Just in case your device runs low on power (for example, if the power is currently lower than 50%) you have to plug in the charger before doing anything else – if you don’t apply this operation, your Galaxy S9 Plus can get switched off while you try to access recovery mode and in that case different malfunctions might get caused.

How to Enter Recovery Mode on Samsung Galaxy S9+

Method 1 – use hardware keys

The first way in which you should try to access recovery mode is by using these steps:

  1. Switch off your smartphone: press and hold the Power key for a few moments until the shut down operation is completed or press the Power key once and select ‘power off’.
  2. Afterwards, press and also hold the Power, Volume Up and Bixby buttons together.
  3. When the Samsung Logo shows up release all the buttons.
  4. The ‘No command’ message should also appear; at that point tap on the screen once.
  5. The recovery mode menu should appear on your Samsung Galaxy S9+.
  6. There, use Volume rocker keys in order to scroll up and down and Power key to select your options.
  7. You can go back into Android mode by choosing ‘reboot system now’.

Method 2 – execute a dedicated adb command

This second solution implies in using a computer, where Android SDK must be set up – so, first of all, take your time and learn (if you haven’t already) how to install Android SDK on your computer: use this guide for the Windows system and this tutorial for MAC OS X / Linux. Also, on the same PC your Galaxy S9 Plus drivers must be flashed – you can get the right drivers by using the Samsung KIES toolkit. On your phone you need to check the USB Debugging feature which is located within Developer Options – so, first you might have to go to About Phone and tap repeatedly on Built Number for enabling Developer Options in the first place. Finally, you have to follow:

  1. On your computer access the Android SDK folder.
  2. From that folder open a command prompt window.
  3. For reaching cmd: press and hold the Shift keyboard key and while doing so right-click on any blank space; then select ‘open command prompt window here’.
  4. Meanwhile, power on your smartphone and afterwards connect it with your computer via USB cable.
  5. Now, in the cmd window type ‘adb reboot recovery’ and press Enter.
  6. The recovery mode menu should be automatically reached on your smartphone.

Method 3 – use a dedicated app from Google Play

This last solution is the most intuitive one, but it requires root access enabled on your Galaxy S9+. Mainly, all you have to do is to install a dedicated app on your phone and use its features for reaching the recovery mode menu. For example you can go to Google Play and download the Quick Boot tool. Set up the app and run in on your smartphone; next, follow on-screen prompts and reach the desired mode.
