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.
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?
