There have been a slew of firmware updates for various Android devices the last couple of days, and this time it is Google’s own Nexus One that has received some OTA love with an update to Android 2.2.1. The size of the update is merely 3.9MB, so it’s likely a minor maintenance release and it will give your Nexus build number FRG83.
There is no official changelog available at the time or even an announcement from Google, but some users at the xda-developers report that the update patches the vulnerability that allows Universal Androot to work, among else. You should only install the Android 2.2.1 update if you’re running build FRF91: the latest stock version of Android 2.2. If you’re using a custom ROM, it’s better to wait until the update gets incorporated into the ROM.
It’s easy to manually install the update. Make sure your battery has plenty of juice before you begin.
- Download the 2.2.1 update from Google’s server.
- Rename the file to update.zip and copy it to the root of your SD card.
- Turn off your Nexus, and start it by holding down the power button and the volume down button at the same time.
- Select the Recovery option and when you see a red triangle, simultaneously press the power button and the volume up button.
- Select “Apply sdcard:update.zip” and reboot your device after the update has been applied.
