Fortigate upgrade error

[shinbun]

Today i upgrade the fortigate 40C, use Tftpd32, but it always show TFTP error: ' Undefined error code' (0) Starting again MAC: 00:xx:xx:xx:xx:xx Connect to tftp server 192.168.1.168 ... What' s wrong with my device? I also upgrade another device like fortiwifi 60c, and it is the same as 40C. My NB is T430, and this didn' t happen before. Firmware 4.3.14 I also use other tftp software, can' t work. Can someone help me?

Never had any problems using Open TFTP Server. Just install the tftp server on your workstation, configure your NIC for a static IP 192.168.1.168/24 and set the listening IP:port (192.168.1.168:69) and set the home directory folder (e.g. d:\Fortigate-Firmware) in the OpenTFTPServerMT.ini. Run the program as Administrator. I also disable the Windows firewall during firmware uploading. From your description of the problem, it sounds like either your workstation' s firewall is blocking the connection or your NIC is not configured for a static IP (192.168.1.168). (I assume you do have firmware available to offer via tftp.) If the 40C is bootable, it may be easier to upload new firmware via the GUI or by USB stick. And if the 40C already has a backup firmware (assuming it is not the diag firmware) you could try booting the fgt into that (from the boot menu).

I try another 40C , it also the same . I find if i boot the 40C ready , i can use tftpd32 to backup/restore from it. But only can' t upgrade the deivce when it start . Internal port 5 the led - 10/100/1000 is flash, act/link isn' t. My colleague also use T430, and he upgrade the 40c , it show (err=1)
