Access Denied 403 Forbidden When Downloading OnePlus Firmware [Fix]

In this guide, we will show you two different methods through which you can fix the Access Denied/403 Forbidden issue when downloading a OnePlus firmware. While the OEM no longer hosts firmware on its official site, there are still quite a few third-party sites and apps from which you can get hold of the same. In this regard, the Oxygen Updater app is the most popular one.

However, you can only get the latest available firmware using that app, downloading an older build is not possible. That is the reason why we have to head over to third-party websites and try to get our hands on OnePlus firmware files, only to get greeted with either the Access Denied or the 403 Forbidden error messages. If you are also in the same boat, then fret not. In this guide, we will make you aware of two nifty workarounds that should address this issue once and for all. So without further ado, let’s check them out.
