Yesterday I tried to upgrade all my old wireless Line6 devices in order to run rf2. I sucessfully upgraded the Relay G30 beltback and receiver. I also upgraded the XD-V30 receiver, but did not manage to upgrade the XD-V30 hanheld. I found the instructions for this device a bit confusing. I got to the point where I should press the power button until the LCD display showed OFF, but no matter how long I pressed the power button, it never showed the text OFF. It was a little unclair which units power button to press, but since the only one that can be held is on the handheld device, I figured it must be this. Has anyone of you sucessfully upgraded this device?
