If you want to just the boot img, then you can easily extract the boot.img from the zip file, but all the other files like system, vendor, etc will be in .dat.br format, which cannot be directly flashed via Fastboot or extracted via WinZIP/WinRAR. Our next step will be for those users who want the complete files which they could be using to flash the firmware using fastboot commands.

  1. After converting the ozip file to a zip file using the python, our next step is to create a flashable file to flash via fastboot, to do it, you must download the URTool from Github.
  2. Extract the zip file to a folder name URTool.
  3. Now move or copy the newly created zip file from the Python folder location to the URTool folder. In my case, my zip file is named Realme.zip.
  4. Now launch the URLTool by double-clicking on the URTTool.bat file
  5. The tool will now ask you to select the firmware file. Since there is only one firmware file inside the URT folder, you should see the firmware file occupy the first spot. So type in 1 and hit Enter.
  6. In the next menu that appears, select the ‘extract android image’ option. This is again the first option, so type 1 and hit Enter.
  7. The extraction process will now begin and you might see a few error messages, ignore them, they aren’t going to be any cause of concern. Once the extraction is done, the tool will notify you of the same.
  8. Furthermore, you will also see a newly created folder named 01-Project inside the URT Tool folder. Go to this folder and you could then access the extracted system, vendor, and other dump files.
