If you successfully remove all of the inside adhesive strip and snapped the outside adhesive then an alternative to step 25 is to start the removal from the inside edge of the battery.
Using the pointy end of the spludger, gently place it between the battery and main board and pry it up along the edge, it will lift easily as there no adhesive on this side.
As you lift it up you will then see the adhesive and you use the flat edge of sludger to break the adhesive off the phone.
Work slowly along the entire length of adhesive, back and forth until it comes away easily.
The battery will bend in the middle along the 2 cells so don't force it without breaking the adhesive as indicated in previous step.
Definitely agree with you, that photo is showing the wrong place to insert the card, right over the volume switch and ribbon cable. The card should be inserted as close the bottom of the battery as possible.
hreat guide but why do you need the heat Gun/shrink?? I'd add a glue gun to secure the motor wires in the arms again...
