Thanks for your post and welcome to the Bose Community.
I'm really sorry to hear that your Home Speaker 500 is stuck updating. I'd love to help with this.
I would first recommend that you factory reset the speaker. This can be done by holding Volume - and AUX buttons for 10 seconds.
Then, head to manually update your Home Speaker 500 on your computer and complete the steps listed.
Once you have done this, please get back to me and let me know if the issue persists.

I am unable to open your website " 203.0.113.1:17008/update.html "
with any of the browser. Please correct this urgently for enable me to update and use my speaker.
Thanks for getting back to us.
I am sorry that this is not working for you. Can confirm, at stage 4, do you see a countdown acknowledging set up mode on the screen of the system?
If you do not see this, it means that the speaker is not in set up mode and the web page will be unreachable.
If you have performed the factory reset and cannot get the speaker into the setup mode, you will need to reach out to your local support team as there may be a hardware fault. You can do this by clicking this link here, selecting your region, scrolling to the bottom of the page, and selecting contact us. If you are in the US or UK you can also reach out via Facebook or Twitter and one of our team can help you there.
