Good day to all, the phone Huawei Mate SE (BND-L34) after the water, was in short circuit, in the area of the RF5216A power amplifier very much all burned to the second layer. As a result, the phone works, but very poor network reception. I need help, I need to call where the pair of contacts from under the RF5216A go and what elements are installed near the amplifier (in the photo where it burned out). Attaching photo.

Phone restored. After examining the Datasheet RF5216 it became clear that the Vcc and Vbat power supply was burnt, using a multimeter, we determine that the largest platform in the second layer (where it burned out) is the Vcc and Vbat bus. Next, the case of technology.
Maybe someone will come in handy, posting photos.
