New to the site and this group Question about firmware numbers and updates

HI all, I’m new… Have two issues that I know of…

#1 updated my Ender 3v2, I don’t think it took, he booted way to fast and the firm where ver. is still 1.0.2

#2 This is why I started this journey… I installed the BT-touch. The z (up and down) is to low. Any help would be great.
