MDR Proxy - firmware sidegrade tool for Sony bluetooth headphones/earbuds



Here you can find a tool which allows us to install previous firmware versions to our Sony bluetooth headphones/earbuds.

Please read the guide carefully!


2023-02-28 - MDR Proxy stopped working after the last update. It's been fixed now.
2023-02-11 - Added the latest Headphones app (9.3.0).
2022-12-09 - Added the 1.6.1 firmware version for WF-1000XM4 to the firmware library.

    1. Unfortunately I can't afford one, and also there's no root access yet for these new players.

  2. Is there any way you can add firmware 1.5.0 to wf-1000xm4?

  3. Hey mrwalkman, you made a mistake with the mdr proxy latest version, if I take the chinese .js file and copy the entire "const infoXML" over then I can finally update, alse it wont trigger an update in the app. the difference in inthe files and you are using http instead of https. Probly why so many are complaining, and not their pc settings.

    1. I didn't change anything related to the MDR Proxy .js.

      I'll look into what's wrong, but it's the same as before.

  4. Can we flash new firmware 2.1.3 for LinkBuds series? I tried to send firmware through Headphones 9.3.0 app but it wont trigger an update in the app.

    2. Yes, now update triggers in the Headphones 9.3.0 app but at the end update fails for WF-L900 firmware 2.1.3.

    3. From the MDR Proxy page on this blog:
      "After the update finished, the Headphones app will say that it failed, but you can check the firmware version by tapping the three dots in the upper-right corner, and then "MODEL Version" (like "WF-1000XM4 Version")."

  6. I used the tool to downgrade from 2.0.0 to 1.3.3,I had one bud replaced due to the battery issue but after downgrade everytime I activate the touch control the voice assistant says "bluetooth device 2 replaced" this didnt happen prior to the downgrade.Any solution?

    2. We are not meant to downgrade anyway, so issues like this may appear. Try to reset the buds.

    3. update:tried reseting and updating to all firmwares from 1.26 to 1.61,issue was still there.Solved by updating back to 2.0.0

    4. Try resetting by opening and closing the lid of the charging case more than 5 times within 20 seconds, while the buds are in the case.

    5. The indicator (red) of the charging case starts flashing. When the resetting is complete, the indicator (green) of the charging case flashes 4 times.
