Hello, it's the same file ... Karol will give you the link which is here on the forum.
By cons, me my headphones never reconnected to Nox after updating on their website ... So above all do not do it, just install the APTX-LL code and nothing else.
I had to return my helmet to Karol and asked for an exchange, because once the update done, no solution to go back ... My headset did not even make a single exit with Nox and went back to the US !!! 😢
