OsmocomBB on Motorola W220

Hi all, I want to know if someone here already tried osmocombb on Motorola W220? This cell phone is powered by D751749ZPH, but at least my model (W220 E2) doesn't communicate with "osmocon". The problem is not serial cable because it work correctly with C115. After some search I discovered the uart is disabled by software, some firmware version let users to enable it after entering on engineering mode (*#**372#), unfortunately my firmware doesn't have this option at eng. mode. You can see a picture of my W220 board here: http://acassis.files.wordpress.com/2011/11/sam_1634.jpg If someone has some idea for an alternative option (JTAG?) please tell me. BR, Alan
