Here is what I have just done to my DS, I don't know how long it will last but it's been doing just fine for the last half hour:
- Take a tiny bit of pipecleaner and bend it round where the hinge was, so it's roughly the same shape and size as the old hinge.
* Take a small square duc tape/masking tape, (about 1cm2) and tape it half over the pipecleaner and half over the middle of your DS.
* Take a small strip of your tape (about 3cm long and the width of the remaining hinge) and stick it down down the exact spot your old hinge used to occupy so that it ends up half on the lid.
- You have to sort of help to poke it back under when you open your DS, but it stops the screen from flopping back, which was the best I could do.
Hopefully this is clear enough, I posted this on my tumblr with pictures so if you want to view it there you can: http://bagadew.tumblr.com/post/149984043...
