CISCO AP 1852I-D-K9 L2 Error detected stuck

Hello everyone,

Maybe someone can help my out. Searched on google about this problem but couldn't find anything useful. 

 After checking the LED Status, I connected with a console cable, only to find that the AP's are hanging at the L2 error. After a few minutes the AP is rebooting and it hangs again at the same screen. 

I tried to do a full reset pressing the MODE button for more than 20 seconds.

but to no avail.  

The cause could be a corrupted image, but according to the log the image verification is ok. 

If someone was in the same position as me, please help... with anything... Thank you!

If am interrupting the uboot process, I am getting to the (RNAQ-C7)#  promt where I have a series of available commands.

 - Suspect hardware fault , you (still) may try factory reset, if not successful the AP probably needs to be replaced (RMA) :

-- Each morning when I wake up and look into the mirror I always say ' Why am I so brilliant ? '
    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

Thanks Marce.
