Inspired by Oli Gill's video on modifying a Lumia 800 with the inductive charging component from a Palm Touchstone battery cover to work with Palm's Touchstone dock.
Steps
1 Remove coil (see pic..removed from a Pixi back cover, but one from a Pre will be the same) ..I found peeling off the black plastic was easy and then remove each piece slowly. The four metal circles can be popped out, and then laid them back down on the black plastic with the adhesive side up so it's one unit again.
Remove the thin black foam from the back of the Lumia 710's battery cover - leaving the foam on didn't work as it's probably too much distance.
2 Place the entire coil unit down on the Lumia's back cover now. I did it as far down as possible so the black plastic just touched the top of the foam over the speaker. If you have enough adhesive it should stick somewhat ok to the plastic cover of the Lumia. Eventually, I may use black electrically tape instead to securely hold everything in place (the area near one of the metals on mine lost it's adhesive so it's sliding slightly if I move the phone around slightly while on the touchstone).
3 Test by placing a led on the two exposed connectors and it worked. Disassemble the phone (youtube video here) and remove the black plastic housing that's protecting the usb port - at 3:40 in the video, you will be able to remove it, then simply place the main board back down and connect digitizer connector back.
4 Soldering a wire (at least a few inches long) to the top of the usb housing, and another to the pin all the way to the right. I could not get it to stick, so I ended up soldering it to the circle connector on the board - see Step 4 Pic. This is not impossible, but does require precise soldering and a steady hand. Use precaution - I used some tape to cover parts of the board up to prevent anything accidents, I would only attempt if you have prior soldering experience as you could damage your main board.
5 I routed the 2 wires through the top portion of the SIM card slot. Not ideal, but it worked as a quick solution. It's important that the wires be as tiny as possible. The sim card for me fits tights once the battery is pushed in. See Pic.
6 Soldering the wires now to the two connections. I used the inductive charging parts from a Pixi back, so the Pre may be similar.
7 You can see how it all looks now once done
8 Now, it works yes, but it's not absolutely perfect like the Pre was. You do have to play for a second or two to get it to sit on the touchstone just right before it's start to charge. Also, due the wires going over the plastic and on top of the battery, the back cover will at times pop open on the left side. I removed the black foam from the back cover, and using a screw driver scrapped off the honeycomb pattern on the back to gain as much space back to prevent the cover from opening, but it does at times.
Next Steps: I may find myself thinner wires or a better way to route the wires to eliminate the back cover from creaking open.
