Good day good hackers:

I have extracted firmware for the Broadcom BCM20702A1 device with id 0489:e07a.

It has allowed as much as being able to scan my bluetooth network for visible nearby devices, but I can't yet pair with my android smartphone.

The process I followed was the following:
Find INF file containing the strings both 0489 and e07a among a driver directory preinstalled in my computer (which came with Windows preinstalled).

Then I found a specific HEX file to be associated with my e07a product id.

I converted it to HCD using the binary compilable from the source available at http://github.com/jessesung/hex2hcd.git

I renamed it according to an error I read from my dmesg, namely:

	bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0489-
	e07a.hcd failed with error -2
	[  270.283264] Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-
	0489-e07a.hcd not found

That is all.
