Fortigate dont start up after upgrading firmware

[#1]

I upgraded my Fortigate 100 from v2.80MR11 to v3.0MR2. After it shut down it would not start again. Status LED is blinking, cannot connect by ethernet or by Console. Looks " dead" . What do I do now? Brdgs Spitsbergen

I had to revert to 2.80MR11. Even then I continue to have problems and am in the process of obtaining a replacement hard disk for my Fortigate 3600. I also could not connect by console after a failed upgrade until I removed power from the box and did a hard restart. If you have already done that, then you probably need to contact Fortinet support directly.

I finally found a consoll cabel that worked and could install an earlyer firmware. When I tried the firmware that did not work i got an error message informing that the .out file was incompleet. So I will download again and try once more.... Brgds from Spitsbergen, 78 degrees north.

OK. I tried mine again on the model 3600. I was able to upgrade to 3.0, but the configuration did not import. So, I am back at 2.80MR11 with a working config. Good luck there at 78 North. I' ve been to Thule, Greenland at 76 North - thankfully in July and August. Brgds.
