All of my arduino's have SMD chips. I could not replace them, not even
if I would need to.

Since the arduino provide the ISP pins for in place programming (a 2x3
pin header), I see no need to physically replace the chips. All that
differs is software and it can be changed any time. You need
a ISP capable programming device (e.g. another arduino with an
ISP-MK2 sketch or a real programmer like the AVR ISP MK2 from Atmel).

There's no rocket science involved.

The bootloader can easily re-programmed with the Arduino IDE (there's a
menu option for it). All you need (again) is a programming device. And
after that, your arduino works as nothing has happened at all.
