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.

014000001500371720430080020002000010001800000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0F0070667D27FFFFFFFFFFFFFFFFFFFFFFFFFFFF45169A1193FBA5FEFFFFFFFF3C000000000000003E000C02FFFF000000000000000001C9
