How to manually update Nexus One to Froyo

Today, I've successfully updated my non-rooted Nexus One to Froyo, the awesome version of Android. But this method works for non-rooted devices, so if you're rooted, you might want to head to XDA developers forum & get some advice. For non-roots, it's real easy. Here's how:

1. Download the official update package from Google. Save the ZIP file into your computer or into your Nexus One SD card. Rename the file to update.zip. Tip: Download the file into your computer, rename it & copy it into your SD card via USB.
2. Power down your device.
3. Hold down the volume down button & power up your device.
4. You'll see the Android boot screen. The loader will try to search & load some files. Once that is done, scroll down & choose "Recovery".
5. When a warning screen appears (a triangle with an exclamation mark), press the power & volume up button together, at the same time.
6. A new menu appears. Select "Apply sdcard:update.zip". Confirm the update.
7. You'll then be brought to a progress screen. This will take about a few minutes.
8. Once the update is complete, your Nexus One will reboot itself (it happened twice for me).
9. Voila! You're on Froyo!
