Verifying the integrity of the firmware image. invalid compressed format (err=1) --------------------------------------------------------------------------------------------------- now this FG is unable to boot because already format boot device. how to solve this? tried a few version, same error.

I have never tried this, but I have heard that putting a hub (or a switch) in between the TFTP server and the FGT may affect performance. I also heard that some servers are better than others. If you can, try a different TFTP product. Also try using a direct (cross) cable in between the FGT and the server. Good luck.

download the firmware again, sometimes i have had to download it three times to get it to work. try with a switch or hub in between the devices if you have not already. try it with a cross over cable only and setting the pc to a fixed duplex. lastly, try a different tftp program like tftpd32 for example. make sure you have the right firmware file for the box (ie make sure you have the FGT300A and not the FGT300, they are different. I have seen this error often, and for no reason, but keep trying and it will eventually work.

download same build 3 times, tried to other build and version, cross cable and fixed duplex, switch in between the devices, different tftp program. i did all the above steps but still not working.. tried to other build, some shows err=2 and some not even finish to upload then it shows unable to open boot image.

format the flash a couple of times. and try again. else, you will have to raise a support call...

formatted more than 5 times.. i tried to upload advanced hardware test image, the result; Enter TFTP server address [192.168.1.168]: 192.168.1.77 Enter local address [192.168.1.188]: Enter firmware image file name [image.out]: FortiGate-300A_HQIP_043.img MAC:00090F8578C9 ### Total 4007909 bytes data downloaded.

Odd I have a FTG-60 and am experiencing the same issue. I just posted a very similar result. I will try what others have suggested, but am not getting a warm fuzzy on this one. I didn' t realize I was wiping the system just thought it was reset to factory and now it is exhibiting the same behavior. If you have any luck please let me know. Thanks

Thanks SecureLayers-Eric I guess it was my tftp version because I switched to the one that you suggested and it worked without issues. Just for the record I didn' t use a X-Over cable or hardset the duplex on the network card. I did download the files again but this was my 3rd or forth time doing this. Thanks for the comments and I am up and running now on the 3.0 code.
