So i have the same problem other users here had : i forgot to turn off my QC30 and the other day it won't turn on anymore. When i try to charge, all i get is the red light. And when i try to update, it starts but lose connection after a while.
My product has more than 1 year, so the warranty won't cover.
It's clear this is a software issue. Is there any solution ?

Thanks for reaching out to the community and sorry for the trouble you're having! There are a few suggestions we recommend that can help you.
Can you please try visiting btu.bose.com to update the headphones?
How long do you have them charging for? Is it a solid red light?
Also, can you please try a different USB charger and cable if that is possible?
Let us know when you get the chance.
Thank you again,

I'm sorry to hear that troubleshooting did not resolve the issues you're experiencing with your QuietControl 30 headphones. Have you tried updating the firmware on a different computer, or alternatively using a different USB port on the computer?
I also recommend performing a product reset on your headphones. This can be done by:
