According this this other thread (https://nfeteam.org/forum/threads/eleaf-istick-rim-c-no-longer-flashable.5251/) the iStick Rim C no longer is flashable: Confirmed via support that the Rim C device is no longer flashable via PC. NFE tools and Eleaf updater do no recognize the device. Latest firmware on the website is 1.08, however the new devices are at 1.12. Something to be aware of if you bought this unit with the intention of flashing Arcticfox on it. Is there anyway to connect to the Rim C and downgrade the firmware to 1.08 so it will work with ArcticFox again?
