    Hello,
    Can you tell which layout is responsible for the memory card? The phone was flooded, I cleaned it with isopropanol. Maybe I missed one item. Huawei P8 Lite - The phone does not read the SD card Huawei P8 Lite - The phone does not read the SD card

    In the picture I put the transitions on the board. I did not find only where the power comes from.

    Nobody solved this problem? I will add that the SD card works properly in another Huawei P8. I also did factory settings and hard reset.

    Look for a voltage stabilizer near the card reader, look at the contact plates if they are tarnished.

    Hello, I got a phone with the same problem, maybe this time I can solve the problem. After flooding, the phone has been cleaned but still cannot read the SD card. Transitions are, only the ldo10 power supply which goes from U301 is missing. Is the U301 to be replaced?

    Is ldo7 a filter supply? I desoldered the filterek and only 0.5V instead of 3V on ldo7. Ldo7 also goes from u301. Huawei P8 Lite - The phone does not read the SD card

    Hello, thank you colleague Plustek for the materials he shared. At TP 2318 without a card I have 1.8V and with a 0V card, i.e. correctly. LDO 10 appears and disappears. Impedance between mass and contact plates about 1000, i.e. something is wrong and according to the algorithm you need to replace D2312?

    Impedance is given with the meter set to measure the diode, with the meter plus on the mass. The values may vary slightly, with significant discrepancies start from D2312.
