For the re assembly of those ones , first locate the two slightly larger screws which goes on top of the iPhone and use a long philips magnetic screwdriver which use the edge of the iPhone as a guide to re assemble those screws . otherwise it will get on your nerves . When doing that , be sure the screen is properly flush with the frame .
Thanks a lot : it is not so difficult provided you follow gently step by step the Ifixit guide .
I used a heat gun which has 15 levels of heat and only needed the no 4 or 5 maximum .
Had to glue again the frame of the macbook pro ( hinges are attached to it and it was broken ( bended) : I used for that rectavit 70 pro ( black)

MAcbook Pro late 2008 needs a new flash drive to be fully operational again !
It is better , instead of using the suction cup , to use small flat end spudger . The suction cup should be used first to detach the window from the gasket , not furthermore as it may brake the glass.
