Good news for those of you with a Google Nexus One running a "non-rooted stock ERE27 system." TechCrunch's MG Siegler reported on Saturday that while charging his Nexus One, he received a message alerting him of an update, which happened to be Android 2.2. Google had previously said that the update would be rolled out in the next few weeks, but I guess they finished early.
Now is the time to pat yourself on the back for choosing the Nexus One, as it appears Google likes to have it's Nexus One be the first phone running Android 2.2.
Gizmodo is reporting that "Not all Nexus One users are seeing the bump yet, but it does seem that Google's starting to roll out the Android 2.2 update..." If you can't wait, then read on for instructions on getting started.
Gizmodo has a walkthrough for installing Android 2.2 on a non-rooted device, writing:
1. rename the update to update.zip
2. Copy it to the root of your sdcard
3. Power off your phone
4. Power on your phone with the power button, volume down key and trackball pressed
5. Enter the recovery mode
6. When you see the Android caution icon press power and the VOLUME UP KEY
7. Apply update.zip
8. Reboot when it tells you to.
A post by rheza02 on an XDA-Developers thread also had a tip for individuals with a ERD79 Nexus One, saying:
Official update patch zip
If you are on a completely stock ERD79 device (including stock recovery image), you can use the official ERE27 update (this is the same as the OTA update). Just download it, put it on the SD card named update.zip, launch recovery (power on with volume down held), press power and volume up when the warning triangle icon appears then select 'apply update.zip'. Sorted
TechCrunch indicates that the update is performing as reported, with much increased performance.
