How To Enter Fastboot and Recovery Mode on Realme C21
What is Fastboot?
Fastboot is a mode independent of the phone’s operating system. It can be accessed without loading the entire OS. Fastboot allows data to be written to the phone’s internal storage. This data can be a custom ROM, a custom kernel, or a recovery. Furthermore, the only way to take advantage of all the features mentioned above is to unlock the bootloader of the phone. Realme phones come with a locked bootloader which can be easily unlocked through fastboot.
What is recovery mode?
Recovery mode is an important part of all Android phones. 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.
Enter Fastboot and Recovery Mode using Physical Keys
The method involves Realme C21’s physical buttons. This is easy to perform and things cannot go wrong.
- Press and hold the power button. Tap on Power off to turn your Realme C21 off.
- Once the phone is off, you have two options:
- To enter recovery mode, press and hold the volume down and power keys at the same time.
- To enter fastboot mode, press and hold the volume up and power keys at the same.
This is the first way to access fastboot and recovery on your phone. If for some reason this method does not work either, then follow the second one.
Enter Fastboot and Recovery Mode using ADB commands
This method is the last resort in case the first one does not work. If you are running a custom ROM and the physical keys are broken, then ADB commands are the only choice. For this, you need to install the latest USB and ADB drivers for your Realme C21.
- Connect your phone to your computer using a USB cable.
- Open CMD/Powershell on your computer.
- Run the following command to make sure the computer recognizes your Realme C21:
adb devices
- Now you have two choices again:
- If you want to boot your Realme C21 into Fastboot Mode, use the following command:
adb reboot bootloader
- If you want to boot your Realme C21 into Recovery Mode, use the following command:
adb reboot recovery
- If you want to boot your Realme C21 into Fastboot Mode, use the following command:
Once you run the following commands, your Realme C21 will turn off and go into Fastboot/Recovery Mode. That is all you have to do. Now you can flash factory images, custom ROMs, unlock the bootloader, and much more.
