Auvidea J120 + TX1 + B102 with Jetpack 3.0

Hi, I have the following setup:

TX1 on J120 carrier board
Jetpack 3.0, L4T24.2.1
Linux kernel 3.10.96-tegra
B102 rev2
As I understand J120 firmware v1,1 (L4T 23.2) supports B102, but newer versions don’t. As I have a newer version, how can I get the B102 to work with my setup?. I can not downgrade to J120 firmware v1.1 as what I have now is what I need for other porpuses.
