[AP3610] ERROR: Cannot boot either kernel image, dropping to interactive shell.

n_n__n_n_ — Wed, 13 Apr 2016 18:37:00 GMT

Hello,

I need for recovery a AP3610 with kernel error. Does anyone know how I can fix this error? Some steps for getting the firmware image on the access point would be nice to have

Regards
Chris

You should contact GTAC for assistance, the unit will need to be replaced or repaired based on your contract agreement (if any) with Extreme.

We've got the same error on multiple AP3705 and managed to solve this issue.
When you get to the interactive shell (console), you can logon with admin, pwd= new2day
Here you can list the files present in you AP.
In our case we saw following list by using the command 'ls':
drwxr-xr-x 0 Thu Jan 01 00:00:41 1970 var
drwxr-xr-x 0 Thu Jan 01 00:00:25 1970 home

-rw-r--r-- 2992 Fri Nov 30 18:31:15 2012 boot_kernel.bak2
-rw-r--r-- 5228994 Wed May 21 09:41:14 2014 primary.gz.uImage
-rw-r--r-- 4974535 Thu Jan 01 00:02:34 1970 secondary.gz.uImage

You can load the secondary image into memory:
fsload secondary.gz.uImage
And boot the image that is now loaded in memory:
bootm

After two bootcycles, the AP booted with the stock image and was up and running.
I recommend to upgrade your AP with your controller afterwards
