It is a secret, I never told others before, but today i'd like to share it, only to those who have iPhone 4s --
How you can change an iPhone 4s, into an iPhone 6! FOR FREE!

1) First of all, open two screws on the bottom (check if they are cross or straight thread)

2) After the screws are taken off, use your thumbs and push the back cover up, then open it.

3) Open the battery screws, pry aside the battery jump ring by a tweezer.

4) Move the plastic pad, and take off the battery (mind there is another jump ring on the other side)

5) Pull out the SIM card slot (or you can't take off the main board later)

6) Take off the speaker ribbon after you open the screws.

7) Open the speaker's fastener, pull up the ribbon (mind there is the double faced adhesive tape, so use the proper force)

Push aside the antenna's join, open the screws.

9) Take off the pad that covers the main board (mind there is a barb)

10) Pry out the camera's ribbon, and take it off.

11) Use the tweezer and
pry out the white water-proof label , reveal the screw, open it up.

12) Carefully push aside these five ribbons.

13) Use the Straight Screwdriver and open a special screw, take off the main board (pull it toward the bottom).

14) Pry out the sheet copper, take off the front camera.

15) Now all the parts are here.
Congratulations! You're only one step from a miracle, the most exciting moment is coming!

16) The final step -- tell your daddy, injuredly and sincerely '
Hi Daddy, I'm sorry but I can NEVER put my 4s back, can you please.............................................................................................buy me a new iPhone 6?" Good luck!
