How to Dump Android Device Partition

In this guide, we will show you the steps to dump an Android device’s partition. There can be quite a few reasons why you would like to get this job done. For instance, if one of your colleagues is having the same firmware as yours, then you can directly extract the patched boot/init_boot file from your device and send it to them, so that they could simply flash the file and obtain root.

Apart from that, this method is also a handy way of taking the partition’s backup so that in the near future, if it gets corrupted, then you can simply flash that backed-up partition file and get your device up and running. Likewise, you can also dump the devinfo partition on your device and read the IMEI number using a HEX Editor. Well, the benefits could go on and on. But without any further ado, let’s now make you aware of the steps to get this job done right away.

How to Dump an Android Device Partition

1. First off, download and extract Android SDK Platform Tools on PC.
2. Next, enable the USB Debugging & OEM Unlocking on your device.
3. Then unlock the bootloader on your device and root it using Magisk.
4. Now open CMD inside platform-tools and type the below command:

   adb shell
   su
   ls -la /dev/block/bootdevice/by-name

5. You’ll get a couple of prompts, make sure to tap on Allow and Grant.
6. Note down the address of the devinfo partition. In my case, it’s sdd1.
7. Now type in the below command to extract devinfo from your device:

   dd if=/dev/block/sdd1 of=/sdcard/devinfo.img
   Make sure to replace sdd1 and devinfo.img accordingly.

8. The file will be placed in the Internal Storage. Transfer it to your PC.
