This actually solved my problem, now it is working just perfect!!. Please 
see this post: 

So on the BeagleBone Family, we use an eeprom id to detect what board you 
have.  In your case, the board eeprom got mis-written too.

Which is easy to fix, near the 5Volt header there are 4 copper holes (TP2 
-> TP5) that's for a LiPo battery, next to that is IC4, followed by TP1.

TP1: is write protect pin for the i2c eeprom.  To allow us to write a 
correct ID, we need to GND that pin (TP1)

On the P9 header:

Pin's 1 & 2 are GND, connect either P9.1/P9.2 to TP1 with a short piece of 
wire.  Then you can exicute


*sudo dd 
if=/opt/scripts/device/bone/bbbw-eeprom.dump 
of=/sys/devices/platform/ocp/44e0b000.i2c/i2c-0/0-0050/eeprom*
