Could it be that the donor's MCU has a unique key?

What is wrong with the patient PCB?

Patient PCB has diode short i installed another diode even after its not powering on and there is no burnt or damages in pcb

Flow a blob of solder over the zero-ohm resistors. They will probably be open circuit. If you don't know what I'm talking about, upload a photo or at least tell us the PCB number.
