Cisco 7960G malformed packets

I have two 7960G phones which were using SCCP

I have just upgraded them to POS3-05-3-00 to work for SIP

SInce upgrading both phones are now sending malformed packets and a wireshark trace show no checksum on the packet.

Can anyone suggest how I might change the firmware as TFTP is the only option, currently using 3CDeamon.

Thanks

John
