ASA 5525 - Software Upgrade Failed via ASDM and FTP

[yuchen.liu1025]

I tried to upgrade ASA 5525 via ASDM from 9.8 (asa982-smp-k8) to 9.12 (asa9-12-3-12-smp-k8) that was directly downloaded from Cisco website, unfortunately it keeps failing and i get this error message "Error writing request body to server" as below and it says "failed verification, reason signature invalid" on Syslog. I did try upgrading with different versions (from old ones to the latest one 9.12.4) but no luck and same error; however, ASDM version was successfully upgraded from 7.8 to 7.12 using ASDM.

Any help would be appreciated. Please advice, thank you!

Hi,
If the signature is invalid, perhaps the image file was corrupted. Re-download the "asa9-12-3-12-smp-k8.bin" file the cisco website and attempt to uploaded again.

Thanks for your reply. i did try again but still same error. seems like now i am now not able to upgrade to any versions :(  

however, a few days ago, i was upgrading another ASA 5525 using the same way from 9.8 (asa982-smp-k8) to 9.12 (asa9-12-3-12-smp-k8), and it was successfully upgraded. is there anything else that might cause this software update failed (uploading failed)? like config or license? Thanks.

Three is a possibility that the storage device on the problem ASA is bad. If you have verified the file hash and continue to have the problem then I would suggest opening a TAC case. TAC can confirm if it is a hardware issue and issue and RMA for a new device in that case.
