I've got two faulty 3DS XLs that I want to fix and in the past, the biggest problem I have is removing the metal hinge part. Apparently I need a very thin but very strong screwdriver to push that hinge part and separate the two cases apart but the last time I did that many months ago, I just end up destroying the plastic hinge part of the bottom 3DS. Is there an easier way to remove it and disassemble it without wrecking the 3DS XL case any further?
