I have some old BT200 phones (Program version 1.1.2.12) which I'm trying to update to the latest firmware. I've set up a TFTP server and unzipped the 1.1.6.37 release image, but when the phone is rebooted it updates the bootloader to 1.1.2.95, but not the Program. The error message on the TFTP server isTFTP error requesting bt200b.bin: File does not existThe file does indeed not exist, though bt200c.bin does. (I've tried copying bt200c.bin and renaming it as bt200b.bin, but that doesn't work.)Has anyone got any ideas? Is the firmware on the phone just too old to update?Pete
