Hi everyone, Do you have occurred this issue? WLC software:7.4 FUS:1.9 When we transfer image to wlc,there is the error as below: ------------------------------------------------- This may take some time. Are you sure you want to start? (y/N) y FTP Code transfer starting. FTP receive complete... extracting components. Failure while validating the signature! FTP Failure while storing in flash! (0) ------------------------------------------------- Is there any workaround except RMA?

>Any workaround except RMA

- Depends , can you still boot the controller ? As for the initial transfer error, verify the MD5-sum for the originial download (of the FUS package).

Try to reboot the device and do an MD5 checksum on the FUS file.

FUS 1.9

This release of the Field Upgrade Software is applicable to Cisco WLCs that are installed with the controller software release 6.0 and later.

the wlc has FUS 1.9，and do not need upgrade it，we need upgrade wlc image from 7.4 to 8.0，we have occurred that issue after we transfer image complete.

Try reloading the controller first and then do the upgrade again.

The reload of the WLC has solved the problem.
