Question about non-Arylic product

Hello,

I have an August WR320 → Portable TV, Portable Freeview Digital TV, Handheld TV, Bluetooth Speakers, Bluetooth Headphones, Bluetooth Receiver, Bluetooth DAB Radio, Clock Radio, TV Aerial
This is working with a linkplay a31 chip, but they don’t support firware update.

Since the last updates from my Arylic product, I cannot link the devices together. Is there a way for me to update the firmware? I tried with the updater, but got the same error as this user → Beta Firmware And Beta App Test Invitation - #55 by W00dwp

Is there a way for me to upgrade the firmware?

Thank you
