I'm having a hard time understanding your question, but I'll answer as best as I can.
If the screen isn't broken or damaged, you can replace the adhesive yourself. If the screen is broken, it would be recommended to replace the screen, which the new one comes with adhesive preinstalled. So you don't need to worry about buying it.
Make sure you remove the old adhesive and residue from the frame to ensure the new screen adheres properly. I personally use acetone, a razor blade, and q-tips to clean the frame off old residue. I'll also make sure the frame is free of bends or dents, especially in the corners. You can file those down, but get a good protective case for the device. Once the new screen is installed on the frame, I'll heat up the edges of the frame around the display to warm up the adhesive and place some weights or clamps around the edges to make sure the screen sticks. I wouldn't use more than a total of 5 pounds (lbs) of weight on the screen and let the frame cool completely.
