To accomplish the unlocking of your Samsung R210 Spex due to forgotten or unknown user lock code I used the following method. First, you will need a data cable. I bought this one from eBay...

Create a folder on your desktop. I named mine Samsung R210.
When you plug your phone into the PC it may be recognized and work. If not you may need the USB drivers also.
Unplug the phone.
Open the Samsung R210 folder and create another folder. I called mine USB driver. Download this driver to the USB driver folder...

In the zip file there's a folder called Samsung_USB_install
Unzip it into the USB driver folder also and click on setup.
Reconnect the phone.
Check the control panel under USB and ports COM and LPT. My phone appeared on COM 10 under ports COM and LPT.
Next, create two more folders inside the Samsung R210 folder. I called them PST and Cricket DLL. Download Samsung PST lite and DLL installer files from the following two links into their respective folders.
Samsung PST lite...

Cricket DLL file for the PST...

Unzip them both into their same folders.
Run the install for PST.
Run the install for the Cricket DLL.
There should now be a shortcut on your desktop named Samsung PST lite. Double click it and you should see the PST Lite window.
Double click SCH-R210 on the right.
This should show you the unlock code. If you don't see the info click the read general information button at the bottom. Write down the user lock code or be sure to remember it. Close the windows. Disconnect the phone. Enter the lock code into the phone and you should be free!
PS, I got my R210 Spex off eBay for $0.01 because it couldn't be unlocked! I have a feeling those prices will go up now that this info is on the web.
