                  0) Check if you can execute the command dir bootflash: without any errors 

  1) Check if there is sufficient free space on the bootflash: , if needed cleanup
  2) Try to install an image from ROMMON  with the "emergency-install"  command ,

Use GUI to upgrade the firmware of the controller from 17.3.X to 17.6.X or 17.9.X.

Hi Leo ,
I try to upgrade from 17.3.x to 17.6.x --- > from 17.6.x to 17.9.x  not success . appear log below 
But upgrade from 17.3.x to 17.6.x --- > from 17.6.x to 17.10.x  success . Why I upgrade from 17.6.x to 17.9.x occur issue ?

                           >....Why I upgrade from 17.6.x to 17.9.x occur issue ? 
    - First before upgrading have a checkup of the controller configuration with the CLI command show tech wireless ; have the output analyzed with https://cway.cisco.com/wireless-config-analyzer/  , correct all errors (if applicable) ,

@marce1000 
I try to upload show tech wireless to that link but nothing happened. Do you have new solution?

  - This should always work ; remember to use the CLI command show tech wireless , not simple show tech ,

@marce1000 
Okay , I start the first line for show tech-support wireless . It's analyze found with 5 Error , 17 Warning ,6 Info  , 12 Processing Errors .

                    >...It's analyze found with 5 Error 
                  You need to correct  all the errors ,

Thank you very much for advisory. After I clear All Error I can go upgrade from 17.6.x to 17.9.x.
