I have done updating by downloading and installing the latest HX Edit 2.52 and the results are disappointing. After finished updated my Line 6 Helix LT it has been corrupted. There are some buttons that are not responding as usual. Such as FS-FS7 (Up/Down), FS2, FS5, FS8, FS11, Tap/Tuner, and Mode. Now FS3 and FS9 will skip 1 preset every time one of them is pressed. Overall, all Footswitch no longer works as it should and the functionality of the unit has been corrupted totally after updated with the 2.53 Helix LT Firmware!. I have already send a support ticket for this issues. Very shocked and dissapointed with the update.
