Question about step 5 of oculus cv1 teardown guide
I opened my box of oculus cv1，but I found my oculus is almost like this
I want to try to repair it ,so I tear down it following the guide （Oculus Rift CV1 拆解），but I don't understand the step 5。How to take out the frame with stretchy black lycra？Here is my picture(http://i.imgur.com/8F9a4cG.jpg
)，does the nail with red drawed need to be taken out？ How to take it out？
Thanks for helping me.
