How to unbrick the Flysky FS-I6X transmitter

Hi,

the files I've mentioned are under:

2nd source

UPDATE 2021:
I have managed to create dfu files containing new firmwares.
I've updated the unbrick pack where now you can unbrick directly to a new firmware without having to start from the 2017 stock firmware.

The dfsue is from www.st.com

Also on my windows 7 machine I didn't need any drivers for my stm device in dfu mode, however you may need to install st drivers www.st.com and also zadig usb drivers from http://zadig.akeo.ie/

good luck fixing your FS-I6X ;)

Edit:
I'm seeing lot of downloads on my server logs. If my video helped you out, please give it a thumbs up, if not let me known in comments below and I'll try to follow up.
Thanks.
