you need some equipment (you don't write anything about it, that's important). Multimert with diode function, laboratory power supply (3 digits after the intersection) and some time to trace the diagrams. Try to get some, there is quite a lot of it in the net.

Separation heater - the soldering iron is an absolutely essential tool. You need to separate the sandwich and find out why you don't have electricity in the installation. There are quite a lot of reasons, you can also find some important hints on my blog, in the advanced and professional section: [link|https://studionapraw.pl/warsztatowe/telefonywarsztatowo/|studionapraw.pl|new_window=true] what I urge you to do (all for free as well). You need to establish the primary supply voltage (3.8V), second order (3.0V, 2.8V) and third order (1.8V). These power the devices necessary to run, without which the motherboard will hang in nothingness. The BGA soldering skill may come in handy here, you should practice somewhere before.
