Yep me too, cannot do a simple back up with the corrupt patches in place about 28A - 30D on mine and trying to overwrite them with a different or blank preset crashes the unit. Is there ANYBODY at Line 6 reading this stuff and working on this problem. Its pretty important as we are advised to back up regularly but I cannot. Nor can I without a back up facility use my Helix Native properly as a cannot exchange patches from the Helix Floor to Native via Edit
