As of 1425 CDT on 22-Aug 2011 it appears HP has unlocked the DEMO units; you may not need the steps below. I'll leave them here for reference.

MOD EDIT (LP): If required, please read "[GUIDE] Turning a Demo unit into a fully functional Retail Unit" posted by mplacido9 for more detailed instructions. Give him your Thanks (by hitting the Thanks button) if you find his in-depth guide useful.

I. HP TouchPad Demo Unit Solution - Bypass Activation

II. Create/Log in to webOS profile for DEMO 32GB Touchpads

Solution with the help of other posts [special thanks to user chekz here on precentral.net and & webOS roundup] This set of instructions will take your DEMO unit 32GB HP TouchPad and place it into Dev mode [and help you update to webOS 3.0.2 if you haven't already done so].Just an FYI, the error that you receive after you flash to regular webOS 3.0.0 or 3.0.2 and can't move forward in registration is: PalmS3036 which is listed as "Device is Locked from doing FirstUse". This leads me to believe, like others, that it is merely a software reason and not a hardware one as to why we cannot use these like regular units.This does remove the DEMO software, allows you to update to webOS 3.0.2, and keeps you from getting stuck on trying to register; however, It is untested on weather you can log into an existing webOS account. I am unable to create a webOS account as I don't own any other webOS devices and I do not know if this will impact your ability to register/unlock your DEMO unit in the future [if HP does so]. I would assume you should be able to use webOS Doctor once again to restore the unit as it was before this solution was developed.Here is where i got the information:====You will need this file:Right click and Save as: http://onebluepoint.net/chekz-devicetool.zip or FileServe Download (again thanks to chekz Steps:1. If you have not already, update to webOS 3.0.2****a. To do this download this: http://palm.cdnetworks.net/rom/touch...2hstnhwifi.jar ****b. Run the aforementioned file by double clicking (You must have Java installed; I did this on Windows 7 Ultimate 64-bit)****c. Continue the setup until you get to the step where you are asked to connect your device with a USB cable. (But, do not connect your TouchPad at this step)****d. On you TouchPad shut down the tablet (you should be able to do this by holding the power option for a few seconds and selecting the "Shut Down" option ; if you can't get that to come up you can force a restart by holding the "Home" button and power button at the same time for apx 5-10sec)****e. Restart/Start-up you device holding the Power button and the Volume Up button (This boots the device into Recovery Mode) You will know if you are successful if you see the USB logo on your screen.****f. Connect your TouchPad to your computer; on screen you should be able to hit the next button to allow your device to be updated.****g. Allow 10-15min for the application to finish; at the end it will tell you the device is resetting. You will see a small HP logo on your TouchPad, disconnect the USB from your computer.****h. Once the upgrade is complete and has loaded you can attempt to login or create and account but if you have a demo unit; you won't be able to register. [aka ERROR CODE: PalmS3036]2. Power down your TouchPad (see step 1d for help if needed)3. Hold down the Power and Volume Up button to allow your device to boot into Recovery Mode. You should see a USB logo on screen. (see step 1e for help if needed)4. On your desktop, unzip the chekz-devicetool.zip file. You might want to copy this un-zipped file to your C: drive to make the next step easier.5. You will need to open a Command Prompt (for Vista and/or Win7 you might need to run as Admin by right clicking on the icon in your Start>Programs>Accessories folder)6. Change to the directory where the unzipped file is located (i.e. C:\chekz-devicetool )7. Connect your TouchPad to your Computer8. In your Command Prompt type the following command:9: You should see the following (your device will restart a time or two):10. Once you see the "Device is ready." You can Disconnect your TouchPad from your computer.11. When you power on your TouchPad, you should go straight to the home screen; by bypassing the activation screen.-----I don't have a webOS Account to log into to see of existing users can log into their accounts.
