    Hello, I have a phone Huawei P8 Lite (ALE-L21), which is after a slight flooding. The problem is that the logo appears for a while and disappears, the action is looped. The disc went to an ultrasonic cleaner but still the same. I uploaded the software but it didn't help either. I noticed that the disc is playing around PMU (U3301), and at U301. The meter set for diode test showed no short circuits on the capacitors. The power supply without battery is 0.6A and with 1.2A battery. Please help. Greetings.

    Check the voltage on L203 with the battery connected, as there is no U201 dropped. As it is - a short circuit on one of the PMU lines.
