Thanks to Danillo for solving this problem.
To revert your currently brick mod back to the stock firmware you need to download the Nuvoton firmware update software from Smok’s website and the original firmware bin file.
Remove the battery from your Smok device
Open Nuvoton NuMicro ISP Programming Tool 2.00
Hold the fire button on your Smok device and connect to you computer using the micro-usb cable (you have to hold the fire button during the entire process)
Once device is connected to the computer you should get a device connected notification on your computer. On the Nuvoton window click Continue and then Connect on the next screen
Click on APROM and select the stock firmware .bin file you have downloaded and ☑ the following
Click Start and your device should be fixed
