Trying to apply JB to a k3 keyboard UK B00A but all I get is a failed with U007 error in bottom corner... FW3.4.3... Any ideas what to do next?
PS incase it had JB applied I tried every JB uninstall I could find and no difference same Error.
Also did factory reset
Actually have the Same issue on a K4NT 4.1.4 fw
