Default Does replacing electronic package need a reflash to complete?

I have a X2 that needs some electronic components replaced. Do I need to reflash the operating system after a component swap? Someone told me I did. I have a X2 that was giving error code e042. I replaced the gyro and did not fix the problem still gives same error code. I was thinking about swapping parts from my working i2 one at a time until I figure out which component is bad the X2. Is there any reason that won't work?

Does the unit start and operate for a period of time, or does the E042 immediately appear upon start up?

A quick search shows:
E042 error which is CU A - BCA down

So it seems that the A side control board cannot communicate with the battery.

There are 2 likely reasons:

A bad battery

A dirty ( or broken ) connector.
Or even a loose wire inside.

Then there's lot more obscure types of errors.

Good Luck
