I installed my Bluetooth driver with the best answer to this question Bluetooth Broadcom 43142 isn't working but after I installed my Bluetooth Broadcom 43142 firmware using hex2hcd method to install the firmware, my Broadcom 43142 802.11/b/g/n firmware conflicts with it each other.

My question is how can I uninstall my Bluetooth Broadcom 43142 or how can I revert it back to the normal (primarily I don't have the firmware of my Bluetooth before) again.

After running

dmesg | grep -i bluetooth

Here's the firmware that I want to uninstall.

[   26.584896] Bluetooth: hci0: Broadcom 43142 Bluetooth 4.0 Adapter

But I don't know how to uninstall it because I installed it using the hex2hcd method then pasting the .hcd file in the /lib/firmware/brcm.

UPDATE:
For now, I use 

systemctl disable bluetooth

to disable the Bluetooth on startup so that I can use my WiFi.

But I still need to uninstall that Bluetooth firmware...

I would blacklist the btusb module and reboot 

echo "blacklist btusb" | sudo tee -a /etc/modprobe.d/blacklist.conf
If you want to use bluetooth then just sudo modprobe btusb
