⚠️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device ZTE Blade A530 with each step description and the required set of tools.
Step 2. Open the back cover
Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.
Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.
⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.
Step 3. Remove the battery
Pry at the end, choose the opposite side to the spring connectors and remove the battery.
ℹ️️️ The ZTE Blade A530 model has a battery Li3826T43P4h705949 with 3000 mAh capacity (aka rechargeable battery).
Step 5. Open the middle cover
Remove the cover with antennas and a loudspeaker. The cover protects printed circuit boards (PCBs). Try to lift the cover by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.
⚠️ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal strength may be quite weak.
Step 6. Disconnect the connectors
Disconnect the coaxial cable connector, cable to the mainboard, on the daughterboard.
⚠️ Do not pull on the cable or pry it with a sharp tool. The connectors are pretty weak and break easily, or the cable falls out of the end (lug).
Step 7. Remove the daughterboard
Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.
ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, vibration motor, spring contacts for the speaker, and an antenna unit.
⚠️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 8. Unscrew one screw
Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw and remove the bracket holding the display connector.
Step 10. Disconnect the connectors
Pry up the connectors of power volume buttons cable, display module cable, inter-board cable, and coaxial cable.
⚠️ Be careful when removing the cables from the connectors. The cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.
Step 11. Remove the motherboard
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the board.
⚠️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.
Step 13. In the display frame remained
ℹ️️ In the display frame remained: the earpiece speaker, coaxial cable.
