No image set

DEX iP721 owners rarely complain about the quality of their smartphone, but users can still face various problems. To solve them, in some cases, a complete disassembly of DEX iP721 is required. In such cases, it is strongly recommended to contact the service center, but if there is no such possibility, then you can disassemble DEX iP721 yourself.

Necessary tools

DEX iP721, like any other smartphone, cannot be disassembled without using special tools. They are usually sold in a kit that usually includes:

  • plastic card or mediator;
  • suction cup;
  • a small Phillips-head screwdriver;
  • isopropyl alcohol;
  • napkins.

You can begin disassembling the device only if you have all the necessary tools. And, since DEX iP721 has a non-removable battery, this process will be quite complicated and requiring accuracy.

DEX iP721 disassembly process

To carry out a careful disassembly of the smartphone, let's take as a basis the process of performing this action in the service center.

  1. Turn off the smartphone.
  2. Remove the SIM card and memory card tray.
  3. Put the smartphone down with the screen. It is recommended to heat the telephone on the separator to facilitate disassembly.
  4. Attach the suction cup to the lid of the smartphone.
  5. With one hand pulling the suction cup and pressing the case, try to insert a corner of a plastic card or mediator under the cover. The thinner it is, the better.
  6. If the lid is difficult to detach, use isopropyl alcohol.
  7. After actions with a plastic card or mediator on the back cover, it completely peels off.
  8. Remove the seals protecting the screws.
  9. One by one, unscrew all the screws that hold the motherboard. But be careful, as the screws can be of different sizes. You need to remember where and which one was screwed in so that you do not face difficulties during the assembly process.
  10. Remove the plastic casing.
  11. Disconnect the battery ribbon cable. Do this using a non-metallic tool.
  12. Remove the polyphonic speaker unit by unscrewing the screws at the bottom of the body.
  13. Remove the SIM card carriage.
  14. Disconnect the display ribbon cable.
  15. Peel off the sticker that holds the battery.
  16. Pull it and remove the battery.
  17. Detach the inter-board ribbon cable that is located under the battery.
  18. Disconnect the coaxial cable and the fingerprint scanner ribbon cable.
  19. Remove the motherboard.

Further actions depend on the purpose of the disassembly. Of course, some steps of the instruction can be skipped, but a detailed illustration containing all the steps helps to understand from which components DEX iP721 is assembled.
