The assemble steps are not included in this guide. I've done all the steps shows above smoothly, but when I tried to reassemble my iphone4, as I did not see the correct way of install it back, the touch sensor cable were broken, I have to bought another brandnew screen for my phone! And, there's quite a few tiny rubber parts in the phone, I just can't find any description about them, one of them were dropped out on my work table, I can't find the right place to put it back... hope there could be some hints for the assembling steps, especially for those tiny parts and cables need to be take care of...
