In this article, you will learn how to enter and boot into recovery mode on your Samsung Galaxy M51. Recovery mode is one of the most important pieces of an Android phone after the actual firmware. It allows users to access certain phone features without having to fully boot up the phone.

This is especially useful in cases where the operating system cannot be loaded. For example, if the phone is locked, it cannot boot properly. However, you can still enter recovery mode and it offers the ability to wipe data, reset your phone, and flash custom ROMs if you have a custom recovery.

Furthermore, you can also make full system backups, which are very important if you tinker with different ROMs. Let's see how to boot your Galaxy M51 into recovery mode.

How To Enter Recovery Mode On Samsung Galaxy M51

There are two ways to enter recovery mode on the Galaxy M51. The first is to use the physical keys of the phone and the second is to use the ADB commands. The first way is always the simplest and most popular. However, the second way is very important if the physical keys on the phone are not working properly.

1. Physical buttons

This is the most popular method. It is also the simplest and is used by most of the users when they need to start recovery.

  1. Press and hold the power button. Touch Switch off. The phone will turn off.
  2. Once the phone is completely off, press and hold i at the same time increase buttons of volume and power.
  3. Hold them until you see the Samsung startup animation logo. A blue screen with a yellow triangle will appear.
  4. Wait a few seconds and the phone will enter recovery mode.

2. ADB commands

If the first method doesn't work for some reason, you can try the second method. This method is ideal if the hardware keys on the phone are broken or if the phone does not recognize the button combination for some reason. ADB commands are the best solution in this case. This is more complicated because it requires proper ADB and USB drivers, as well as a computer.

  • Samsung Galaxy M51 USB Driver | Download
  • Go up Settings> About phone> Software information and quickly tap seven times up Build number. This will enable Developer Options. Go to Developer options and enable the USB debugging.

Make sure you correctly download and install the USB drivers for your Samsung Galaxy M51. If you don't, the computer won't be able to recognize your phone and you won't be able to use any ADB commands.

  1. Connect your phone to your computer using the supplied USB cable.
  2. Open the command prompt from the ADB installation folder and run the following command:

    adb reboot recovery

The phone will automatically shut down and go into recovery mode.

Recovery mode walkthrough for Samsung Galaxy M51

Now that you know how to enter recovery mode, it's a good idea to know what the options provided in the menu do and when you should use them.

  • Reboot system now: this option will simply reboot the system. The phone will boot into the operating system and you will be able to use the phone normally.
  • Reboot to bootloader: this option starts the phone in download mode. This is a special mode for Samsung phones where One UI firmware and kernels can be flashed via Odin's flash tool.
  • Apply update from ADB: this option is used when you want to update your phone or update stock OTA files by connecting your phone to your computer and running the required commands.
  • Apply update from SD Card: this option is used when you want to update your phone or update serial OTA files which are located in the external SD card of your phone. This is a better way than ADB because it doesn't require the user to have a computer. Everything is done in the phone.
  • Wipe data / factory reset: this option deletes all applications installed on the phone. A factory reset is recommended when you want to flash a new custom ROM or mod which could cause a bootloop if the data is not deleted.
  • Wipe cache partition: this option deletes the cache and dalvik cache from the system. This is recommended if something on your phone keeps crashing.
  • Mount /system: this option allows you to mount a partition as a system or data. It allows you to edit everything in that particular partition.
  • Power off: this option simply turns off the phone. You have to press the power button again if you want to turn it on.

These are the most important recovery options you may be able to use. Some other more developer-focused options include:

  • View the recovery logs
  • Run a graphic test
  • Test the local settings
  • Lack of boot from storage

Here's how you can boot your Samsung Galaxy M51 into recovery mode. You can clear your data cache, perform system backups, ZIP flash updates, and even perform full factory restores.
