The method of manual update doesn't depend on PC or MAC. It just needs a browser and a micro usb to USB cable. If the old firmware is not available on BOSE website, I am happy to give you a link from my cloud. But it's your choice. The update is very simple using the manual method. It's your choice; as to whether you want to stay unhappy with the BASS for however long Bose take to push the next update (they are quite slow), or fix it. I know which one I would go for 🙂
I would absolutely expect them to. You could say that you wanted to update firmware manually, so followed their guide, and it got bricked. Firmware is firmware, doesn't matter if it's old or new firmware.

Sorry to hear about the issues you're having with your SoundTouch 300. Is the Bass module producing any audio? If you look on the back of the module, are there any LED's lit up?
