Pirelli never syncs

Hello everybody, I bought several Pirelli DP-L10. I checked out the master branch of Osmocom, changed the console.h and sercomm.h, and enabled the CONFIG_TX_ENABLE option. The code compiled successfully. I loaded the compiled firmware onto the Pirelli with osmocon, and after it loaded, I ran cell_log and mobile. But the phone never syncs to a cell. I first tried with the "no stick" option. But after this, I tried to find a strong cell (I used a Blackberry 9300 for this, it has a nice engineering screen). I found cells from -76 dbm to -104 dbm. I tried them all with the "stick xxx" option, but still, the phone does not sync to this cells. The last thing I tried was using the binaries a friend provided me. He compiled the code on his computer, he tested those binaries at his home, with his Pirelli, and it worked: he could sync. He sent me those same binaries, but still no luck, the phone cannot sync. I have tried this on 4 different computers, 2 different versions of Ubuntu, on Debian, and on a Mac. It doesn't seem it's an operating system problem, but I wanted to test it anyway. The only thing it's different from you it's I live in the Caribbean, but I have GSM networks on all four bands. Now, if I use my sim on the Pirelli, with the original firmware, it works. I can even make a call, so I think it's not a hardware problem. I tested with Nokia C118 on a 850Mhz network, but same story. I'm posting my mobile.cfg file, and some logs. Thank you for your help.
