Cisco 3602 AP Continuously Rebooting due to Corrupt IOS Image

Tayyab831
Level 1
Level 1

Dear Community Members,

I am experiencing a problem with my Cisco 3602 AP, which is continuously rebooting. It appears that the IOS image is corrupted. I would like to interrupt the boot sequence and enter ROMMON mode to delete the problematic image and install a new one. My goal is to convert this AP into an autonomous AP.

Could you please advise on how to interrupt the boot sequence and install the new image? I have tried the following methods, but none have worked:

  • Mode button
  • Ctrl + C
  • Esc key

Below are the AP CLI outputs for reference:

Dear Marce 1000,

Thank you for your support. The issue has been resolved by following step
8. The problem was actually with the mode button—it wasn't being pressed
properly. I opened the back cover of the AP, pressed the button correctly,
and successfully interrupted the boot sequence.

Thank you so much.

     Does executing Step 8 and the rest following  make any difference ?

In ROMMON, force the AP to boot the RCV firmware.  If not possible, format the flash of the AP and upload the RCV file using xModem.  The latest CAPWAP image compatible for the 2600/3600 is 17.12.4 and can be found HERE.
