i need to change my phone's firmware, from sccp 8.0.1 build 051117A to sip 8.0.1 build 060412A
the tftp server is my machine using pumpkin, isolated and connected to the phone thru a x-cable
i'm trying to perform this change by converting gk<mac>.txt file with cfgfmt.exe
the phone requests normally the gk file, and receives it, but when it is trying to request the .sbin file, i see the tftp error message: tftp timeout and tftp error code 5, with error message "undefined error"
i tried several degrees of timeout setting in tftp server, it seems it does not affect this misbehaviour
i know it's difficult to determine what specific error it is, but has someone seen sth like that?
The phone is probably requesting also an xml configuration file, check requested files via tftp, make one avail to the phone with the correct load version in it.
Hope this helps, please rate post if it does
