You could roll back to 743 and that would help rule out a hardware fault

I've thinked that option, but knowing so little about these makes me wonder does downgrading affect anything else? Does it reset my settings and so on? Just got everything finetuned I don't want to go back to square one. I do have settings backup, so if I go 743 can I keep/restore settings over that if even necessary?
And roll back is done from the usb with image...? Sorry, lot of questions, but I'm learning....
