My version was simple:
B44EB2 - B0 0E
B44EB4 - B0 0E
B44EB6 - B0 0E
B44EB8 - B0 0E
B44EBA - B0 0E
B44EBC - B0 0E
B44EBE - B0 0E
B44EC0 - B0 0E
B44EC2 - B0 0E

And the checksum at the end of fw_all was corrected.

Probably patch is superfluous but it works. I'm not sure if setting a filed for 3760 means that 3790 gets features too or maybe this patch will block features in other models.
