S4 Mini Boot Loop Problem

Hi, I have a Samsung s4 mini and it has a boot loop problem. It starts up and it sticks at the Samsung logo, and i have tried all the procedures for trying to get rid of the problem, except the last one. The last remedy is for me to factory reset my phone which I don't want to do . So my question is - Is there any part that I can replace in the phone itself that can stop the problem? Because I have another S4 mini which I can take parts from.
