Pls HELP ME: wrong upgrade process for 1120B

I did a upgrading procedure for 1120B from 12.3.7 to 12.3.11JX1. I didn't use the upgrading tools, I just used the web page for upgrading. Now the AP can not work, it's rebooting all the time.

Who can help me for the recovery?

THX!!!

Re: Pls HELP ME: wrong upgrade process for 1120B

Hi Jing,

This release only contains a partial LWAPP image.

**Note: This release must only be loaded onto access points at the factory or by using the Autonomous to Lightweight Mode upgrade tool. Your access point might become inoperable if you install this software without using the upgrade tool.

Cisco IOS Release 12.3(11)JX provides support for the lightweight access point protocol (LWAPP) for 1100, 1130, 1200, 1230, 1240, and 1300 series access points. When you use the Autonomous to Lightweight Mode upgrade tool to upgrade one of these access points to this release, the access point communicates with a Cisco wireless LAN controller and receives a full LWAPP configuration and software image from the controller. This release also functions as a recovery image if the access point fails to receive a full image from the controller.

Using a TFTP Server to Return to a Previous Release

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

--------------------------------------------------------------------------------

Step 1 The PC on which your TFTP server software runs must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30.

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 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point.

Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 5 Disconnect power from the access point.

Step 6 Press and hold the MODE button while you reconnect power to the access point.

Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button.

Step 8 Wait until the access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.

Step 9 After the access point reboots, reconfigure the access point using the GUI or the CLI.

Hope this helps!
