Yes, that’s true. You can boot into any recovery of your choice on your Android phone by following this guide. No need to flash and replace the stock bootloader. Though I have tested this method on Nexus devices only but I am pretty sure that it’ll work on other phones as well. Custom recoveries give you a lot of options for performing some important tasks, like backup and restore your phone and wiping out caches.
Prerequisites
- An unlocked bootloader – It is just a command away on Nexus devices. Google will give you very useful links depending on your device type.
- ADB with Fastboot – Check out this link: http://www.jailbreakeye.com/android/install-adb-fastboot
- A custom recovery image – TWRP or CWM (check the Download recovery or Download touch recovery columns)
Guide
- Copy the downloaded recovery image (.img file) to the folder where you have placed your ADB and Fastboot.
- Launch terminal (or command prompt on Windows).
- Navigate to the directory where you have placed the ADB, Fastboot and .img file together.
- Shut down your phone and reboot into boot loader. For nexus devices, simply hold volume down + power to start up the phone.
- Connect your phone to your computer.
- On terminal (or command prompt) window, write fastboot boot <img file name>, e.g. fastboot boot twrp.img.
- Your phone will restart and will boot into the recovery mode.
That’s it. As simple as it can get!
