Forcing the NoDo update for the Samsung Focus has been achieved, and results in significant performance improvements.
Below is a step by step starting from a completely unhacked device.
First- Developer unlocking your phone:
You need these tools:
Steps for unlocking:
To Deploy an application you need the following instructions:
The first XAP you need is a registry editor to prevent relocking.
Download the TouchXperience Registry Editor from here.
On the phone, navigate to
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg] "PortalUrlProd"="" "PortalUrlInt"=""
and delete those registry values (not entries)
Download WithinRaphaelâ€™s Samsung Registry XAP here, and deploy it using the Application Deployment app which you used above. Run it on the device, and it will take you right to the Operator key. Change that key to 000-88 .
Lastly, to get Zune to deliver you the NoDo update (from this XDA-Developers thread)
1. Download USAIP.pbk from here, then open it and connect to EUROIP PPTP Hungary
(This connection is automatically closed after 7 minutes!)
and connect your phone to the PC
(If "Network Connections" doesn’t open, apply the registry entry from here and reboot your PC)
2. Disable WLAN (Wifi) in your phone, but be sure to have FLIGHT MODE off and that "Use cellular data connection to check for updates" is active
3. Start Zune and keep it running all the time
4. Switch to cellular settings on the phone
5. Manually search for an update within Zune (Settings > Phone > Update)
Important step 6.:
After a few seconds (about 10-15 seconds for me) disable data transfer on the already opened settings tab on your phone
–> The update shows up!
(You can now terminate the connection and download the update using your "normal" internet connection)
If it doesn’t work (cognizable by the fact that you get a time out error) retry steps 5 and 6 and vary the time until you manually disable data transfer! (step 6)
Some users report this tutorial works with WIFI! So if you aren’t successful try to use your phone’s WIFI connection instead of your cellular data connection (be sure to set cellular data off this time).

A trick to get the right timing (thanks Hardmen):
Get a stopwatch and stop the time until Zune says "no internet connection". Subtract 0.5 to 1 seconds and that’s the time you have to shut off the data connection.
As can be seen in the video below, the results are worth it. (Via Winrumors)
