Android has come a long way in terms of hardware and software. Especially in software, the difference between the one we had a couple of years ago and what we have no is day and night. One of the beauties of Android is being open source. And we love to tinker around Android so much so that there are times when some people would run a different ROM every single day.

Custom ROMs are built by modding the stock ROMs. To modify the stock ROMs, we would need to extract the stock ROM Firmware file and then modify the stuff we need. We even wrote a tutorial on how to extract system.img and system.new.dat files on Windows. Turns out, manufacturers are using a different method to deliver the updates to their phones.

Usually, when I extract the OnePlus stock firmware zip file, there would be multiple “.img” file such as system.img, boot.img etc. But it was different this time. Seems like OnePlus has decided to take a new route to deliver the OTA Firmware updates to its devices. Turns out the change is due to the introduction of the A/B system update.

  8. This will start to extract the images within the payload.bin file to the current folder you are in. Wait for the process to complete.
  9. Done!
Please note that the last step will take a considerable amount of time as the volume of data being extracted is huge.

All the contents of the payload.bin file will be extracted in the same folder as you are currently in. If not look for a folder named ‘output’. The contents would be present there. This is the easiest way to extract payload.bin Android file on Windows.
