Untouch525

I was having no issues with the K90 keyboard out of the box, but unfortunately I decided that I wanted to actually take advantage of the G-key functionality. After attempting to do the firmware update I'm now left with, essentially, a bricked keyboard. I tried to work through the steps posted in the OP, but at step 6 the only other listed function is "USB Input Device" which windows tells me is already up to date anytime I attempt to install another driver. I've tried a myriad of the other fixes posted in this thread to no avail. At this point I don't think it's worth the shipping cost to RMA this keyboard. I mean there isn't any guarantee the one I get back isn't going to run into the same exact problem. I'd rather just put that shipping money into a product that I won't have to worry about dying on me just because I want to actually use some of the features that were sold to me.
