There is already a Wiki entry on this topic and as this is another method, I don't want to alter it. I'm also unsure of how to fit in this alternate method. If someone is up for the task, please feel free to add this. Also, I realize this information exists elsewhere. I'm trying to consolodate it into one source and provide a step by step set of instructions for those not too familiar with Linux.

Requirements:
Windows XP
VMWare Player (28,902KB)
Ubuntu VMWare Player Virtual Environment (264,676KB)
Linux flasher (645KB)
770 XTerm


Step by Step Instructions:
1.) Install the VMWare Player. The install is straightforward.

2.) Unzip the Ubunto VMWare Player Virtual Environment to a folder of your choosing. "My Documents\My Virtual Machines" is recommended. (Note that another sub-folder called "Browser-Appliance" will be created if you leave the zip file's directory structure intact.)

3.) Start VMWare Player. When prompted with "Browse for virtual machine configuration file" navigate to "My Documents\My Virtual Machines\Browser-Appliance" and choose "Browser-Appliance.vmx". Ubuntu will now boot.

4.) Click on the "Applications" menu in the upper left corner of the screen. Navigate to the "Internet" sub-menu, and select Firefox Web Browser (v1.5.0)

5.) Download the Linux flasher by entering the URL "http://www.maemo.org/downloads/d3.php" manually, or navigate to this document via Firefox and click on the link provided at the beginning. Save the file. (The default location will be the Desktop)

6.) Click on the "Applications" menu in the upper left corner of the screen. Navigate to the "Accessories" sub-menu, and select Terminal.

7.) Type the following (Linux commands are case sensitive!):
8.) Type the following (Linux commands are case sensitive!):
9.) Turn the Nokia 770 off.

10.) Plug the USB cable into the Nokia 770.

11.) Hold the 'Home' button down (the bottom-most one) and power the device on (keep holding down 'Home'). The Nokia logo appears on a white screen and after a few seconds the USB connectivity logo appears. Release the 'Home' button. The title bar of the VMPlayer window should now list a Nokia USB device.

12.) In the terminal again, type the following (Linux commands are case sensitive!):
You should now receive a message that the device is in R&D mode.

13.) When the Nokia 770 reboots, you will notice green text on the white screen with the Nokia logo that displays Kernel information. There will also be a wrench icon beneath the logo. If XTerm is not already installed, install it now.

14.) To obtain root access, type the following in XTerm on the 770 (Linux commands are case sensitive!):
15.) Finally, switch to the root user itself (Linux commands are case sensitive!):
16.) You now have full run of your system. Please be careful, and as always, do this at your own risk. If you don't have any linux experience, I recommend playing around in your Ubuntu Virtual Environment for a while to get used to the commands. Should you screw up your 770 at this point, the only way out is to reflash.
