If the LTE version being worked on, ensure the sim tray is removed before attempting to isolate the battery.
If the model you are working on is the T585 you will need to carefully pry up the blue antennae cable and disconnect the sim card slot from the motherboard.
Overall easy enough to follow but with speeded up sequences there's quite a bit of rewinding to properly view some steps. One point to note is that the video does not mention removal of the sim or sd card readers, this isn't easy from an existing mid frame bezel. May be easier to source replacements to fit into a new bezel,
As per the previous comment.
It has been mentioned here through virtue of the fact that Joe in PA queried what the rubber grommets were for after prying off the home button ribbon cable, if this is for a replacement LCD it might be worth adding a step advising that these need to be removed carefully by sliding them up and off the pentalobe screw brackets with tweezers as they’ll need to be moved across to the replacement screen, 3rd party replacements don’t come with them fitted.
