Cisco Wireless Access Point from Lightweight Mode to Autonomous Mode

AP that is running in Lightweight mode:

System image file is "flash:/ap3g1-k9w8-mx.124-23c.JA8/ap3g1-k9w8-xx.124-23c.JA8"

AP that is running in Autonomous mode:

System image file is "flash:/ap3g2-k9w7-mx.153-3.JC1/ap3g2-k9w7-xx.153-3.JC1"

If there is “LAP” or “CAP” in the part number, the AP is shipped in Lightweight mode.

Product/Model Number                 : AIR-LAP1262N-A-K9
Product/Model Number                 : AIR-LAP1242AG-A-K9

In Lightweight mode: 

AP#config t
^
% Invalid input detected at '^' marker.

You need move to debug mode:

AP#debug capwap console cli

But as for me better move to recovery mode:

---Push reset bottom

---Power on

---after 10 sec unpush reset bottom and go to recovery mode:

  set IP_ADDR 192.168.100.100
  set NETMASK 255.255.255.0
  set DEFAULT_ROUTER 192.168.100.1
  tftp_init
  ether_init
  flash_init
    
  tar -xtract tftp://192.168.100.101/images/c1140-k9w7-tar.124-21a.JY.tar flash:
