First of all you should check the image you' ve download. 99.9% sure it doesn' t match the checksum Secondly download the right firmware image. Connect with console cable. Format boot device. TFTP the firmware (tftp32 is freeware) and then restore config. Good luck

Did you check the MD5 checksum of the firmware image? and are you sure that you have the correct version for your fortigate?

You might want to use another TFTP server. Which one are you using?

I`m using WinAgents TFTP server

Hello londo4 , You may find some more details about the TFTP servers and MD5 in this article : " Troubleshooting Tip : message ' invalid compressed format' during TFTP procedure" http://kb.fortinet.com/kb/microsites/search.do?cmd=displayKC&docType=kc&externalId=FD31018 -J.

There is a FGT60B firmware as well as FWF60B firmware. Be sure you have the correct one... (As Eric stated earlier)
