Glorious GMMK-RGB Barebones Keyboard - Row 4 Not Working Full Size Fast Shipping

I have not tried to troubleshoot this it is an extra keyboard I have and the fourth row of keys is not working, I'm sure they can be fixed with a simple reset or a software that is used with the keyboard, I'm not sure. You could simply buy this, and if it doesn't work well, you could definitely trade it in, or you could contact Glorious. *Condition (LOOKS) 10/10. Looks and feels brand NEW. This is why I believe it may be a software and not a hardware issue. It COULD be a hardware issue though, so you are responsible for return shipping if you choose to buy this and decide to return it. *If you're looking for an Ergonomic Keyboard and Mouse that are both wireless and come with a unifying receiver checkout my Logitech keyboard listing! *All clothes/Items come from a smoke & pet-free home and are packed professionally and measured using the standard methods.
