re the Torx screws and 3 or 4 I bought a set that only went down to 4 and it was fine. I am UK.

The middle picture in step 4 was awkward. The plastic bit came off on mine and I ended up separating the front and back just enough to get something in there and push the clip up. This was the only way I could do that step.

For the charging coil placement - visible marks were left where the arm that looped around to the back was stuck. And I stacked the old battery on top of the new battery and lined up the charging coil with the old battery, a family member then slid it out of the way and this worked easier than measuring etc.

The battery connector in step 5 was very solidly in place. I had to focus on the right hand side of the connector as it is shown in the picture and this is very well seated by the adjacent screw hole. Keep your nerve, its quite firmly on there and took some minutes to get off.

No major issues through this one

Just finished this - Was fairly straight forward and only issues were freeing the battery (Used hairdryer to soften the glue) and getting the logic board back in which was fiddly as some thing thats very fiddly. Result is great - very satisfying when it restarts. Display is slightly brighter than it was so may have to recheck some connections or maybe its just a warming up thing from first use.
