hi, the S9K have same system than lot of bitmain miners... so , i have the SD unlocker if you want , just use "17 series unlocker" on my website https://www.djayos.com, use same methode than S17 
With very lot of respect, if i say process, i also check it and tested, so, "17 series unlocker" work perfectly with S9K / S9SE ...
OF CORSE , after unlock you need install CORRECT firmware ! so , only good model ...
