@valentas the more you try to power it on and have it connected the greater the likelihood you are going to shorten it out and cause further damage. so for now hold off messing with the phone. A few thing you want to try first before you go into the component levels. “After that i put all the PCBs into a small bowl with 75% disinfection alcohol and put some warm heat for like 5 mins. After that i left it overnight in rice to dry out. “ Start by using a higher percentage of isopropyl alcohol. 75% is '''not''' enough for a proper cleaning; you will still have 25% of other liquids (mostly water) in that. Check for 90%+ for that. You '''do not''' need to place it in rice. '''Rice does absolutely do nothing'''. Remember that you must totally disassembly your phone and '''remove all''' EMR shields from the board. If you do not remove those, you are not cleaning the majority of your board. Use this guide [guide|5825] to see how to clean it. It was written for an iPhone but all the steps are still pertinent to your phone as well. Once it is properly cleaned, you must replace the battery. Only after all that can you properly troubleshoot your phone. The voltages you get now are not proper to power on your phone.
