Cisco ap1815i bootloader

[MED Amine MB]

Hi,

I have a cisco ap1815i that boots in (BTLDR) mode .

I tried to do the reset with the mode botton and power cycle and didn't work .

It doesn't support any known command (set , dir flash ,init flash or boot ).

I didn't find any record of this in the internet .

Regards,

Console into the AP and reboot. 
Post the entire bootup process.
