Have you tried this from Cisco site:

Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:

Step 1 The static IP address of the PC on which your TFTP server software runs should be between and

Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.

Step 3 Set the timeout value on the TFTP server to 30 seconds.

Step 4 On the PC where the TFTP server is located, perform these steps:

a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.

b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View; then uncheck the Hide extensions for known file types check box.

Step 5 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.

Step 6 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 7 Disconnect power from the access point.

Step 8 Press and hold MODE while you reconnect power to the access point.

Step 9 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.

Step 10 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.

Step 11 After the access point reboots, reconfigure it using the GUI or the CLI.

I have no power adapter for it, we currently use it with a poe switch, which is serving production APs at the moment.

Also, I just noticed you have the "enable" command on that list. Can you enter that command then list what available commands you have.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

when I do enable it asks me for the password which I then supply but doesn't change the available commands like on a normal IOS router

ok, your first suggested solution worked until a certain point. it wouldn't find the file on the tftp server, even tho I matched the file name and extension to the exact thing the log said. so while trying to resolve that I found this other article which allowed me to do the process manually:
From Article: https://supportforums.cisco.com/thread/2228852

changed to my own name of course

You need to perform these steps:

Restart the Access Point
While it loads the image in flash, press Escape, you’ll enter ROMMON mode:
The system boot has been aborted. The following

commands will finish loading the operating system




Set the IP address for the gigabit 0 interface:
ap: set IP_ADDR

ap: set netmask

Initialize the tftp, ethernet and flash subsystems:
ap: tftp_init

tftp_init success: You can now use tftp file system!

ap: ether_init

Initializing ethernet port 0...

Ethernet speed is 100 Mb - FULL Duplex

ap: flash_init

Initializing Flash...

...The flash is already initialized.

Load the image from TFTP and extract it to flash:
ap: tar -xtract tftp:// flash:

After it’s done, set the correct bootimage:
ap: set BOOT flash://ap3g2-k9w7-mx.152-2.JB/ap3g2-k9w7-xx.152-2.JB

Boot the system:
ap: boot

after this It became an autonomous device and now im able to manage it.

thank you for your help
