I also had issues with my Cobb/JB4 stack.
Firstly, I had troubles with the flash install because the JB4 firmware wasn't updated. It works fine once you update the JB4 to the latest March 12 firmware.
You need to ensure that the JB4 Map is Map 0 (pass through) when doing an install or map update.
Then, I also had the unrecognised rom issue. After emailing Cobb, they told me that I need update my Cobb AP to the latest BETA firmware. To do so, open your Cobb AP manager, go to updates, make sure that "Check for beta firmware" is ticked. Your ROM won't be recognised if you use the Alpha firmware.
Then you should update to the latest firmware to support your BMW.
Then you should be able to test the Cobb maps.
FTW!
