Besides the MAC address, there are other parameters in the SPROM where Broadcom accounts for the specific amplifiers and radio of a device. When you wrote the SPROM for board A into board B, these were also overwritten. Fortunately, there are not many of these. The list includes the antenna gain, the pa0bx parameters, the max power out, and the idle TSSI target.
I am assuming that you do not have a copy of the original contents of the SPROM for board B. I have saved copies of all the boards that have been rewritten All of them have 0x3C for the maximum power out, and 0x3E for the idle TSSI target, thus I think we can rule out those parameters. I do see only two different sets of parameters for the pa0bx parameters as follows:
Board pa0b0 pa0b1 pa0b2
Your A 0x12A0 0xFB77 0xFEAC
Other 0x 119A 0xFB93 0xFEA5
The following SPROM content has the MAC of your board B and the other pa0bx values. Please try it.
