AIR LAP 1142N-E-K9 doesn't boot anymore

[as00001111]

Hey all,

I got a central WLC 5008 and a lot of 1142 Access Points.

One of them doesn't boot anymore. I don't know what happened.

When I console to it, it says:

The system was interrupted or it encountered an error
during initializion of the flash file system.  The following
commands will initialize the flash file system and finish
loading the operating system software:

    flash_init
    ether_init
    tftp_init
    boot

I can't even delete the multiple-private file:

ap: delete flash:private-multiple-fs
Are you sure you want to delete "flash:private-multiple-fs" (y/n)?y
File "flash:private-multiple-fs" not deleted -- invalid argument

A reset doesn't work either.

Can you help me? Is that a hardware issue?

 - Possibly hardware , have  a factory reset , check if that helps :

I can't perform a factory reset. When I press the MODE button, cli always goes into ap: prompt.

It's a loop.

Sounds like corrupted flash, possibly faulty flash or hardware - so you need to try ROMMON recovery.

If that doesn't work replace the AP.

             - What does the (probably rounded)  LED indicator has to say when the ap is powered  up ?
