Hi, apologies in advance if there is a thread regarding all of this, I've searched but don't see my specific issues mentioned.
I just updated to 4.0.6 from a previous OS version (I know, I should know which one exactly, but unfortunately I don't) and everything has gone extremely wonky. I can't do a backup because it hadn't occurred to me to back up things before I installed 4.0.6
All of my delays and effects from previous patches are gone, and if I hit (for example) the delay button to edit/add, instead of the effect parameter popping up, the UNDO button lights up, and I can't even exit from there. I've tried reverting to a previous OS version, I believe I've got 2.5.0, but that doesn't seem to work either. My question at this point: Is there a way to factory reset this thing and load 2.5.0? I've searched online for an OS higher than 2.5.0 other than 4.0.6, and can't seem to find anything. Any helpful suggestions are greatly appreciated!
