imei & serial number changing to "repair" kernel panic and reboot loop

Hey guys...so far in the past questions like this have been shunned and hostile responses received so before I go onto asking my question I have no Applestore in my country I'm only interested in the actual way of going about it, no legal issues cause

I'm not in the US and as far as I've researched it's not illegal to change IMEIs in my country.

So now onto my problem

I've an iphone 6+ that sometimes will be in a bootloop and sometimes boot up to the springboard and work just fine and then randomly reboots to the boot loop.

From my googling I've found it to be a kernel panic that causes it to randomly reboot but for what ever reason it will bootloop most of the time with the apple logo then off then apple logo again .

If it is going to boot till springboard it will shrink the apple logo like in this video

I've not seen any damage on the board and if it boots to springboard it will charge and connect to computers normally like nothing is wrong.

The only thing I can think of is to change the imei and serial number of another motherboard to this one and change out the board so how can I go about doing this?

A software method would be preferable.

Or if there is a fix for this kernel panic and boot loop I'd like to try it out.
