Bought new bladeRF, very low sesitivity

Hi bladeRF-ers,
I bought a bladeRF last week and after updating the firmware and FPGA, doing the calibration and installing everything, it seems the board has a sensitivity close to zero. Board version is v2.0, Firmware 2.0 and FPGA 0.6. I mounted 2x VERT900 antennas.
I tried various gain settings with no success, usually the noise is increased only.
As an example, a GSM channel on 952.0Mhz should come strong as I see it with RTL and USRP but with bladeRF it is very week, see the attachment.
The apps that works with USRP and RTL do not work with my bladeRF board. I tried open-lte, LTE Cell Tracker, even kalibrate-bladeRF (although I heard it does not suppose to work).
I need to know if the board is defective or not. It will be wonderful to have an app that sets the RX/TX gain at some levels and then send an receive the signal through a physical loopback (I can make one with a 40dB attenuator). And then if the received signal is not within a range decide the board is defective. Does anyone have that?
Thanks,
BCD
