Frequently Asked Questions

Is this flex cable compatible with the Huawei P40 Lite 4G?
No, this component is specifically intended for the Huawei P40 Lite 5G version (CDY-NX9A / CDY-N29A codes), as the internal architectures of the 4G and 5G variants use distinct lengths and pinouts.

Does replacing the main flex resolve charging issues?
If the charging failure is caused by broken internal traces on the power supply line between the lower board and the main board, changing this flex resolves the problem. However, it is essential to test the charging port and battery beforehand to confirm the diagnosis.
