Replace main PCB of 1100D: How to flash ROMx.bin to new board?

[eloml]

Hello all.
I've got a (used) main PCB as a replacment for my 1100D. The original mainboard is close to dead, I fear: I need to remove the battery for more than an hour before I can power it up again. But I was able to get Rom0.bin and Rom1.bin from it and would like to flash these to the replacment PCB in order to get the calibration data to it.
Is there a way to achieve this (for a non-developer)?

I can look into it; already reflashed my own Rebel cameras in the past in order to learn how to use these routines, but didn't try on 1100D yet.

You can find me either on IRC (mostly offline, so you need some patience), or by sending me a PM.
