ngxing (windows 10 tested) + mapped worldwide.bose.com configuration with ssl certificate valid till 19 May 2023

Note: This work was done based on the bosefirmware/ced#4 thread so read it for more information in case you need help!

Instructions

1. extract the nginx.zip archive to c:/ (c:/nginx) to make it work without modification of the nginx.conf file.

2. go to c:/nginx and install rootCA.crt to Trusted Authorities

3. replace (or modify if needed) C:\Windows\System32\drivers\etc\hosts with the 'hosts' file in this repo

4. start c:/nginx/nginx.exe and you should be able to open https://worldwide.bose.com/connected_device in your browser and see lines like URL=https://raw.githubusercontent.com/bosefirmware/eb/master/drowsy_charger/index.xml with no ssl errors. Just make sure you see raw.githubusercontent.com/bosefirmware there, this indicates the nginx proxy is doing its job!

5. open https://btu.bose.com/ and install the updater app (if you don't have it already) and you should be able to connect to your headphones/etc

6. if the above works press a d v up down and you should see a "super secret" menu allowing you to choose the exacted firmware version you need to install

PS: I was able to revert my Bose QC35i to firmware 1.0.6 from 3.0.3 on Win10/Edge with this setup (:

bose's Issues

This method is still working?

Hello sir, If this method still works, please give more specific instructions. For example, where can I download the nginx.zip file? How do I install rootCA.crt to Trusted Authorities? I have a bose quietcomfort earbud that is flashing red and white error and now it is very difficult to find working instructions to downgrade the firmware to fix it. Thank you veru much!
