Earlier this morning, it was discovered that Google was upgrading
the Nexus One to the impressive new Android 2.2 operating system
with an over-the-air (OTA) update. However, it quickly
became apparent that this wasn't being delivered as a general
release for everyone in possession of a Nexus
One -- the update was only being pushed out to review samples
that had been sent out by Google earlier this year.
Now, however, some rather inventive folks have found the direct
download link so that everyone with a Nexus One can enjoy some Froyo
sweetness. The only catch is that the Nexus One must be in
non-rooted, stock ERD79 form.
You can download the update direct from Google here,
or get a mirror download here.
User rheza02 over
at XDA-Developers describes the update process as follows:
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'.
2.2 (Froyo) brings with it a new JIT compiler for faster
internet browser performance, native internet tethering and Wi-Fi
hotspot, and support for Adobe Flash 10.1.
