Hi,
In my E4407B had to replace the A4 CPU board, desoldered and replaced the eeprom to keep my serial # but lost my options which were 1D6, 1DR, A4H, AYX, BAA, AYZ.
In addition, I would really appreciate it if you could help me enable a few extra ones: 219, 226, 229 and J36.
My serial is US40241687 and Host ID is: 4AF673B0
BR, 73
Serge
