How to Boot into Galaxy S9+ Recovery Mode

This is a detailed guide for how to access Samsung Galaxy S9 Plus recovery mode using all available methods. The new smartphone comes with some exciting new hardware such as the variable aperture camera. In this article, however, we would be focusing on how you can access the built in recovery mode for modifying your Galaxy S9 Plus. Apart from modifying, you can also use recovery to perform tasks that are otherwise unavailable through the normal Operating System. For example, if you wish to clear the dalvik cache, you would require the stock recovery. Accessing this built-in partition doesn’t void your warranty and you can easily get back to the normal mode afterwards. Ahead, we have a detailed step by step guide for how to access recovery mode on Samsung Galaxy S9+.

The new flagship is just reaching the hands of customers and developers hence there is not much third-party development going on. Gradually, utilities like TWRP and root will pop up for the Galaxy S9 Plus. Do keep in mind that whether you have a custom recovery installed or not, the procedure for accessing it remains exactly the same. With the stock recovery, you can wipe cache, flash an update package and even factory reset your phone. Let’s see how you can access the recovery mode on Samsung Galaxy S9+.

Some Android phones, like the Sony Xperia series do not come with a stock Android recovery at all, and in that case, we would have to load a custom recovery first to that phone and then enter it. However, Samsung Android phones do come with a stock recovery and some Android specific functions i.e. installing a software update, doing a full hard reset etc. are only performed through a Recovery Mode. Whenever you do them, the phone first takes you to the stock Android recovery and then performs that specific function.

What is Recovery Mode?

Recovery is something built natively into the Android source code. Almost all phones ship with the stock recovery unlocked and open to the user. Samsung in this case is also very open. You can easily access the recovery partition and there won’t be no damage to your warranty.

Functions available in this mode are primarily maintenance oriented. First function you are able to utilize is the ability to apply an update. Very handy feature indeed. Once a firmware is released by Samsung, it is pushed to all devices. After getting downloaded, phone boots into recovery and flashes the update. Also, if you don’t get the update straight from Samsung, you can download the update zip from the internet and apply that as well. This helps when you are experiencing long delays in updates.

Afterwards, you would notice wipe data or factory reset option along with wipe cache. These are used when you are short on internal space or just want to reset your device. Deleting cache only deletes temporary files while wiping data resets whole of the device leaving no user data behind. If you face some force closes or slow-downs, using these will surely help.

Alongside the benefits it’s our duty to also provide warnings. As this is a crucial partition which has advanced capabilities otherwise not available in the stock system, it can cause prolonged problems. If you are not sure what you are doing, don’t select or implement any of the options. However, measures are in place to reduce errors as much as possible. Validation checks are used before flashing any file so that fatal problems can be avoided.

Custom recoveries are built on top of the stock ones. This means the stock functions will all be there. The difference is the capabilities are enhanced. A popular Custom recovery like ClockWorkMod (CWM) or TWRP (TeamWin Recovery Project) give you the ability to create system wide backups, manually format each partition, fix permissions and much more. Even if you install a custom recovery, accessing it will remain exactly the same.
