Nexus One Android 2.2 Update for EPE54B – Updated

I know Google is pushing the Android 2.2 OS update OTA this week but I haven’t seen the update notification yet so I figured I would take care of business on my own this morning. I’m using the Nexus One or N1 for short on the ATT wireless network so my 2.1 update 1 build is EPE54B. I was able to download the 2.2 FRF85B update from Google at:

http://android.clients.google.com/packages/passion/signed-passion-FRF85B-from-EPE54B.75b107d6.zip [Google didn't leave that hanging around long. Here's another link I found on Rapidshare, http://rapidshare.com/files/404464202/signed-passion-FRF85B-from-EPE54B.75b107d6.zip.html, checksum is the same so it looks legitimate.]

Steps to upgrade from EPE54B to FRF85B:

1. Download the Android 2.2 firmware package.

2. Rename the file to update.zip and copy it to your microSD card via USB.

3. Power down your Nexus One.

4. Hold down the “Volume Down” button as you power the phone back on. A screen should appear showing your phone’s system searching for various files.

5. Scroll down to “Recovery” using the volume down button and press the “Power” button.

6. When you see the triangle with an exclamation point and Android symbol, press the “Power” and “Volume Up” buttons at the same time and wait a minute for the
menu to appear at the top of the screen.

7. From the menu that appears, select “Apply sdcard:update.zip.”

8. Wait for the install to complete and your N1 will automatically reboot.

9. Check your system settings, Android version, it should now show 2.2.

Good luck with your upgrade.

Follow-up, after 24 hours or so running 2.2 there definitely is a performance improvement in responsiveness on my N1 and the mifi feature in 2.2 is pretty much worth the upgrade by itself.

And after two days on FRF85B I received a “System Update” overnight to build FRF91. Apparently Google wasn’t quite done with 2.2 or maybe they had to fix the calculatoin they use to display the signal strength bars ;)
