That would be a workaround, but no solution. A new firmware would
be a solution.

You need the firmware's source code to fix it, unless you want to spend endless
hours reverse engineering hex files.
Apart from that, by fixing the firmware on your own you will void the manufacturer's 
warranty.

But, what about a third option?:

Contact the manufacturer, tell them about the broken firmware and ask
for a software update. If they won't do this, then send the device back and 
request a refund.
