Sometimes the iceriver miners can become stuck or hung and can no longer mine. Typically, they either boot loop or show both the red and green lights. The only option you have then is to factory reset, and depending on firmware, that will soft lock your device and you have no access. By buying this device, you gain full ROOT AND FILE SYSTEM (SCP CONNECTION) to ANY Iceriver device. Let me know if this helped any of you! Works on the KS0 Ultra, KS5 series, and technically with some slight modifications should work for any other revision.
