Line 6 HD PRO X Was boot looping over and over for the longest time. I could sometimes get it to boot fully like 1 out of 30 times. Then it would work fine, and sound great... but very unreliable. Its now kind of working again, boots ok maybe half of the time. I can play through it fine when it boots ( sometimes after booting it will reboot), as well. I did a diagnosis test on it and it says that the SDRAM is failing (F). what can i do to fix this, if this is even why this device is acting up.
