@med72966 does it truly overheat or does it just say it is overheating and shuts down? This "And my touch is flickering sometimes without even touching it" that could be your display. Remember that the touchscreen and the rest of the display are sandwiched together. So it will affect all of those. The no charging could be a battery issue but could also be an issue with the USB port as well as the PMIC power management IC. Not sure if you are up to measuring voltages on your circuit board etc.

Start with the screen and while you work on that, take some good picture of your motherboard. that way we can try and point things out for you and hopefully help you to get your phone fixed. How are your soldering skills of really, really small components on a fully populated circuit board :-)? Your phone actually hase 6 thermistors that can shut your phone off. We just have to figure out which one may be causing it :-) There are two just above the USB port area that are around the Touch Sensor IC......makes me wonder if that would be a good place to start looking :-) WEll let us know when you have the display off and let's see what's going on there.

All of this now puts you between a rock and a hard place. Could be the display/Battery/USB port or could be an issue around the Touch IC which makes this a board level repair. Special tools, special skills, and lots of patients required.
