The worry here is that you separate the cover display of the touchscreen, or 6 smaller than the first 2 screws to open iphone and especially hope that the collage was not too "successful" ... In my case there were 2 screws on 6 totally impossible to defeat and therefore the construction stops there ... To make it simpler and guaranteed result, better opt for the LCD + Touch directly (instead of 25 ~ 10 but in my case I would have won here directly put a little more expensive ...) => 2 screws, 3 déclipsages and iphone is like new.
