Hi, the files I've mentioned are under: http://netlion.eu/flysky_fs-i16x_unbrick_pack.zip 2nd source https://drive.google.com/file/d/1qg0BvNWWmt4S4Mi5mcGW2WSmOosEMujf/view?usp=sharing 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.
