@Oystein: From the ML archive, I see you have a close version match,
does EFR works on your nanoBTS ?

A little more infos for reference:
The two nanoBTS are both 1800 round model (non-edge). Both 139 but one
is 139_ and the other is 139U.
I can't see any visible difference in the PCBs of both. I found what I
think is the jtag port to the ppc, I might try to dump the flash ...
As far as I can tell, the only non-volatile storage are the 4 flash
chips next to the MPC855. 4 chips of 1Mx16, that's 8Mo of firmware.

The one where EFR doesn't work:
 - Marking on the side: nanoBTS model 139_
 - ipaccess-find infos: Location 2='BTS_NBT131G'  Equipment
Version='111_029_23'  Software Version='120a002_v149b42d0'

The one where EFR works:
 - Marking on the side: nanoBTS model 139U
 - ipaccess-find infos: Location 2='BTS_NBT131G'  Equipment
Version='139_029_41'  Software Version='120a352_v267b22d0'
