Update failed (Mac OS Catalina)

Hey guys, when trying to update the firmware for my Soundcore 2, I get “update failed” after selecting the firmware in the drop down and hitting “next step.”

I’m trying to update using the firmware that was emailed to me from customer service, A3105_SoundCore 2 V053-201904.FW

I’ve never updated my firmware before, bought the device about 3 years ago.

Mac OS Catalina 10.15.5

Please advise, I have no idea what to do next.
