I've recently installed Linuxmod SP1 on my Z6 in order to gain FTP/telnet connectivity. Although I flashed the phone successfully (it's a simple process, at least on a Z6), I can't seem to establish a stable FTP connection between the phone and my linux box, as the phone loses synchronization in less than a minute. On the bright side, USB connectivity now works flawlessly, so I'm happy all the same. Perhaps you should try flashing your phone as well.
