Converting AIRLAP1142 to autonomous

I have an AIR-LAP1142 that I'm trying to load the autonomous software onto.  I reset the AP with the mode button held down as per instructions.  When I release, it attempts to download c1140-k9w7-tar.default from my pc running tftpd62.  Several connections are made and then it eventually times out.  I tried another machine (also win7 x64) and it fails there too exactly the same.

TFTP logs show:

Connection received from on port 1024 [18/05 17:22:04.269]

Am I missing something?  Is there a trick to get this to work?

Converting AIRLAP1142 to autonomous

Looks like the trick is to release mode as soon as it turns red.... not wait until it says waiting for release on the console.

So this means your issue has been resolved?

It actually should not make a difference when you release your finger after the LED turns to red. It should usually work if you directly released your finger after turning to red or if you waited sometime! I've never seen a difference in my practice.

So now it is working fine if you directly release after the LED turns to red?

To convert the units from LWAPP to IOS I use the mode button procedure. 
Just in case here it is.
First of all, I would like to let you know that there is a problem if you
don't see the extensions of the files in your folders. The problem is that,
when you rename the file, you just rename the name, and not the extension.
The solution for this is:
Go to the folder that contains the IOS image and go to the tools option in
the window bar.Click on folder options
Go to the view tab and uncheck the option that says: "Hide file extensions
for known file types".
After doing that, now you can rename the IOS image file (step 3 below), and
then continue with the proper steps to recover the IOS Image.
Step 1 The PC you intend to use must be configured with a static IP address
in the range of to
Step 2 Make sure that the PC contains the access point image file (such as
c1140-k9w7-tar.124-25d.JA1.tar for an 1140 series access point) in the TFTP
server folder and that the TFTP server is activated. If you don't have a
TFTP Server, you could get a free one (which is one we recommend) at the
following link:
Step 3 After downloading the proper IOS image file from the Cisco's Web
site with your CCO (do not extract the file), just rename the AP's image
file to c1140-k9w7-tar.default for an 1140 series access point.
Step 4 Connect the PC to the access point using a crossover cable (or any
CAT5 that connects fine, it depends on your PC).
Step 5 Disconnect power (the power jack for external power or the Ethernet
cable for in-line power) from the access point.
Step 6 Press and hold the MODE button while you reconnect power to the
access point.
Step 7 Keep holding the MODE button (never release it since the reconnection
of the power) until the status LED turns red (approximately 20 to 30
seconds), and when it's red, now you can 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, you must reconfigure the access point
by using the Web-browser interface or the CLI.

Also make sure that the PC with the TFTP server has no firewall enable or antivirus blocking the transfer.
