The IPhone5C has plastic rear housing instead of a metal one like iPhone5S. The metal plate on which the phone’s circuits are mounted is glued to the plastic case. Therefore if the rear case is damaged or scratched in a way that needs replacing, one would have to dismantle the entire phone. After that one would have to rebuild the phone into the new metal frame that is attached to the inside of the new back case.
Special tools are required to pry the case and disassemble the entire phone.

These are

  1. Plastic opening tools
  2. Small suction cup
  3. Tool to eject SIM card
  4. Utility Scissors
  5. Spudger
  6. Tweezers
  7. 2.5 Flathead Screwdriver
  8. Philips #000 Screwdriver

Before doing anything, switch off the phone and using the pin, eject the SIM card from the phone.
