Downloads

  • Magisk Module | Download [ADB & Fastboot for Android NDK]
  • TWRP Image | Download

Important

Make sure to keep the TWRP image you downloaded on the Download folder on both the devices. For the convenience of using I suggest you rename the long TWRP file name into a simple one like twrp.img.

Connecting the Two Android Devices

Take a compatible USB cable and connect both the Android smartphones. Upon establishing a  correct connection, a pop-up will show up asking permission to allow USB Debugging.

  • A checkbox will be there that says always allow from this computer. Tap on it.
  • Then tap Allow.

Enable Super User Access

  • Open Terminal app
  • type su to grant superuser access
  • tap on Grant

Now, to check for a connection, type the following

adb devices

Upon executing you should see the list of connected devices.

Install TWRP on Target Smartphone

First, you need to enable fastboot mode on the target device

  • So, on the first device type the following in the Terminal app
    adb reboot bootloader
  • Now give the following command to locate the TWRP image file you downloaded earlier
    cd/sdcard/Download
  • Now you need to check whether your target smartphone supports seamless software updates or not.

Here we will have twp situations depending on whether your target smartphone has A/B partition (seamless update support) or not.

If your smartphone supports A/B Partition

  • Open the Terminal App
  • Type the following
  • Tap on Install > navigate to the Download folder containing the twrp file
  • Tap on Install Image tab
  • Select the twrp image file
  • Next tap on Install Recovery RamDisk
  • Swipe to confirm flash
  • Wait for a few seconds as the TWRP is installing.
  • The tap on Reboot System

A/B Partition Not Supported

If A/B partition is not supported, then we will directly use the command from the terminal app to permanently install TWRP. However, A/B partition supported or not you need to enable fastboot mode on your target device as I have mentioned in the previous steps.

  • Open Terminal app on the rooted 1st smartphone
  • Type the following to flash the TWRP
    fastboot flash recovery twrp.img  
  • Now, type the below command to reboot the system
    adb reboot recovery
    
  • Once installed successfully, the target smartphone will reboot to TWRP.
  • Remove the USB connector

So, that’s how you can successfully install TWRP on your choice of Android smartphone without using any computer. You can now root, install your choice of custom ROMs, and mods on the device. I hope that you found the guide useful.
