Hope you can help with this. I have a WLC 4402 that was showing an error on the seconday image when looking at the MONITOR section on the web interface. So I decided to upload the same image that we are using on another WLC 4402 that we have and after doing so and restarting the system, now it's not doing anything. It's not throwing the CISCO screen when consoled to it, not responding to pings to the service port, nothing. Only the STATUS and PS2 leds are lit on solid, apart from that, is doing nothing.
I tried to press ESC a lot of times on the console screen, tried different conection speeds, different console cable. NOTHING!
Please help. I'm really coming mad (insane) on this one.
When in the cisco screen do a break (its on the screen) and load your old version of code.

I tried to upgrade the cisco boorloader pf WLC 4402 from version 4 to 7.2. I updated ER.Aes FOR 7.2 (EARLY RELEASE.aes). It was updated perfectly and then I rebooted controller....now i can only see blank screen from connected console.
I tried the flash of other lan controller but its not working because the issue is in the ROM as the boadloader file is in the ROM which is corrupted now
I want the solution to upgrade the boatloader file inside the ROM.
