Below you will learn how to boot your Samsung Galaxy A51 into recovery mode. Recovery mode is an important part of all Android phones, including the Galaxy A51. It is a stand-alone piece of software that allows users to access a number of functions without having to boot the entire OS. This is a very useful feature, especially if the firmware or the OS of the phone is corrupted.
For example, if your Galaxy A51 is bricked, which means that is has a corrupted firmware or a bad program, it will not boot. It will show the Samsung logo during boot, but it will never go past it. However, you can still boot into recovery mode. From recovery, you can reset the phone, flash custom ROMs, mods, and much more. You can also make backups of the entire data the phone has. Now let’s see how you can boot your Galaxy A51 into recovery mode.
How to enter recovery mode on Samsung Galaxy A51
This is the most popular and easiest method. All you have to do is press a few buttons and you are done.
- Press and hold the power button. Tap on Power off. The phone will turn off.
- Once the phone is completely off, press and hold the volume up + power keys at the same time.
- Keep them pressed until you see the Samsung boot animation logo. A blue screen with a yellow triangle will appear.
- Wait a few seconds and the phone will go into recovery mode.
Recovery Mode via ADB Commands
This method is optional, in case the first method does not work for some reason on your phone. If the physical keys are broken or the phone refuses to recognize the key combination, then you can boot in recovery mode by using ADB commands. This is more complicated because it requires proper ADB and USB drivers, as well as a computer.

Now that you know how to access the recovery mode, it is a good idea to know what the options provided in the menu do, and when should you use them.
- Reboot system now: This option will simply reboot the system. The phone will boot the OS and you will be able to use the phone as normal.

- Apply update from ADB: This option is used when you want to update your phone or flash stock OTA files by connecting the phone to the computer and performing the required commands.
- Apply update from SD Card: This option is used when you want to update your phone or flash stock OTA files that are located in the external SD card of the phone. This is a better way than ADB because it doesn’t require the user to have a computer. Everything is done on the phone.
