Upgrading Nexus One from Android 2.1 to Android 2.2

Well it turns out that I had version 2.1 update 1 installed (build id ERE27) and my Nexus One would not update to Froyo (build id FRFxx).

So, I had to find out how to do it manually.

I used this article to run the update:

How to manually install Android 2.2 on your Nexus One

Tips:

• Be patient; Ready Everything!
• This will update you from ERE27 to FRF50. You can use the same instructions to get to FRF83. (download FRF50 to FRF83 update here).
• after step 8, you will see a box with an arrow coming out of it and a little droid. It takes a while, but don't panic. the phone is installing the update.
• The phone will do a few restarts on its own. Let them run.
