How to Manually upgrade primary image on WLC4400 ?

Hi, Mark

I downgraded the WLC4400 software from 4.1.171 to 3.2.215
Maybe my downgrade procedure was not correct.
Now the both the primary and backup image is 3.2.215.0 (as below)

and WLC4400 cannot boot successfully.
(WLC4404 crashed after bootup 2 minutes)

=================================================
Boot Options

Please choose an option from below:

1. Run primary image (Version 3.2.215.0) (active)
2. Run backup image  (Version 3.2.215.0)
3. Manually upgrade primary image
4. Change active boot image
5. Clear Configuration
=================================================

How can I manually upgrade primary image ?
( above option 3 "Manually upgrade primary image")


Best Regards,

Re: How to Manually upgrade primary image on WLC4400 ?

Hi,

Now, my WLC4400 cannot boot successfully. It would crash after boot up 2 minutes.

So I can not upgrade software use GUI or CLI upgrade procedure.

I think the only way is use the "Manually upgrade primary image" as below.

=================================================
Boot Options

Please choose an option from below:

1. Run primary image (Version 3.2.215.0) (active)
2. Run backup image  (Version 3.2.215.0)

3. Manually upgrade primary image
4. Change active boot image
5. Clear Configuration
=================================================

But, after I chose the option 3, it appeared

"!!! WARNING updating using .aes or unapproved files will disable this unit !!!"

How to reover it ?

Best Regards,

Ching-Yuan Yeh
