Booting to TWRP

  • Reboot your device into TWRP, assuming you have installed it previously

Retrieve the location of our target partition

Warning

From now on we will assume you are trying to extract the boot partition, if not, replace "boot" with the name of the partition you are trying to extract.

  • Now, we need to find the location of our target partition, as it is different for each device. To do so, run the following command on your PC:
adb shell ls /dev/block/by-name/
  • This is going to output a lot of lines, with each partition name having its mount point. Look for the line that says boot

Let's make an image of the partition:

adb pull /dev/block/by-name/boot boot.img

If you did everything correctly, you will now have your boot.img. Enjoy! 🥳
