I just unboxed by iStick Rim C I purchased from Divine Tribe along with the V4 atomizer. I downloaded the latest tools and firmware and connected the iStick Rim C with 2 different USB cables. It is recognized by my PC as an HID compliant device. I launch the "NToolbox.exe" file (also tried to "Run as Administrator") and select firmware updater but it never gets beyond "Waiting for Device" (I've tried three different computers; my home PC and laptop both with Win 10 and another laptop with Win 7; I've also used 2 different USB cables) . I've tried turning the battery off and on and plugging the battery in with the firmware updater already running but the battery is never found. There are no error codes, it just never proceeds past "Waiting for Device". I've tried both USB 2 & USB 3 ports on the PC's, the previous version of tools and also connected it in safe mode from page 17 of your manual with no luck. The battery is still detected as an "HID Compliant Device" but still isn't found by the firmware updater. I'm not sure what else to try so any help would be greatly appreciated.
