This is rather a belated post which I should have done last July 6 when at last the long wait for the Over-The-Air (OTA) update from Android 2.1 (which was the default installed version when I got the Google N1) to 2.2 (Froyo). I was trying before to use the update function of the GN1 (Settings->About Phone->System Updates) since I heard the news about the available OTA updates but without success. I have tried downloading several update files and installing them based on the instructions I got after scouring the Internet but again the usual errors. So I decided just to wait when the OTA will be available comforting myself with the thought that at least this is the safest way to do it.

So here it is: just so I won’t forget what I have done and to share to others who might need the info (we need to share, right?). Its actually simple:

* Try entering *#*#checkin#*#* (type *#*#2432546#*#*) into the GN1 phone dialer to force the update.
* Wait for ‘checkin succeeded’ notification
* Then immediately turn the phone off and then turn back on
* Then go to Settings->About Phone->System Updates of your Google Nexus Phone

My Google Nexus One has Build EPE54b 2.1-update1 with Android 2.1 prior to the update.
Its now Android 2.2 with latest Build FRF91.

Thanks to jchocolate99 post at nexusoneforum.net.

BTW, from the comments I read from the forum. There is no guarantee for this work and will depend on your location. At least worth a try especially for people who doesn’t want the tedious other way of updating and of course have the patience to wait.
