Xiaomi 4C Mobile Phone Water Intake Maintenance Record

At the seaside in summer, my millet 4C accidentally fell into the water, and the screen was black in an instant! But breathing light and the three lights below are on. Quickly use Xiaomi Assistant to export data. After some tossing, it was finally successfully repaired. Below, I will share my experience, hoping to help those in need.

Rust on tail plug small plate and flat cable.

After disassembling the machine, it was found that the tail plug small board and two flat cables were rusted, so the OEM small board was replaced. But the back cover can't be closed, so I have to buy another tail plug-in small board, motherboard cable and boot cable. This has improved a little, but the screen is still black.

Screen components, help

I observed a dark line in the dark, so I bought a screen component and replaced it according to the tutorial. Finally, the long-lost Xiaomi icon appeared, and the mobile phone came back to life!

Pay attention to disassembly.

When disassembling the machine, be sure to pay attention to anti-static, disassemble the cable lightly, and take more photos to record the screw position. Only in this way can we avoid unnecessary losses.
