Question : Problem: Problems flashing LWAPP to IOS Autonomous mode Cisco Aironet 1131AG Access Point

I have read all of the posts regarding similar issues with upgrading from LWAPP to Autonomous Mode. Here is my case:

I have 2x Aironet 1131AG Wireless Access Points.

One is brand new and has the latest IOS version flashed to the device
The other was shipped to me from Hong Kong and was flashed with LWAPP

I have followed the steps located on the cisco website as per re-flashing the device using TFTP

Below is the output of the session & error codes.

The IOS tar file is the correct file as we used it to flash the identical AP previously.
My TFTP directory contents are as followed:

$ ls /tftpboot
-rwxrwxrwx 1 nobody root 5560320 2008-07-08 21:14 c1130-k9w7-tar.124-10b.JA.tar

md5checksum matches cisco's website
