WLC2006 Upgrade Failure

When I upgraded WLC2006 software and fail, after reload , WLC will enter "grub>" mode. This way is similar to router rommon. There is no narration on cisco websites.

Who can help me to solve this problem?

Thanks.

If the WLC goes to grub mode after rebooting then it may be due to hardware failure.

Contact cisco for a hardware change.
