Those are both for the glass-backed model. Mine has a full aluminium shell with plastic ends. I was hoping it would be similar to the 6.1, where the screen connector is under the digitiser at the front, but it isn't. I need to get the inner frame out of the aluminium shell to access the rear / battery area but I can't find any guides or teardowns online for this model.
OH I see. I don't know that particular model well. They change so much for each version. This shows a tear down for what I believe is the verson you are referring to (not glass back), but alas it doesn't seem to address the display itself.
Yeah that video is still a "glass" back (I don't know if it is glass!) - but you can see the back panel being removed with a heat gun. You can't do that on my model - its a single solid piece of aluminium. I have removed the old broken screen and can see that the main 'carriage' for the inner part of the phone looks like it is press-fit into the AL shell - but I don't really want to try and lever it out without knowing what I'm doing.
