FAQ
-Does this work on any other phones besides the Nexus One? Absolutely not! Do not do it!
-Will this void my warranty? How do I know it's legit? No, this won't void your warranty. The source above is the exact location that people who legitimately got the OTA update downloaded their update.zip files from. Also, after the update has been applied, it is impossible to distinguish between those that got it OTA or forced it.
-Does this wipe my settings or applications? No, the update only touches your system files and radio. All your apps and settings will be preserved!
-If I force update with this method, will I still receive an OTA update? No, once you've updated, you will not get any further notices to update.
-If I'm in an unofficial country (not launched by Google yet) with an unlocked N1, will I still get the update OTA? I'm not certain yet, but as confirmed by many users, this update will work on your phone. There is no danger is forcing the update, rather than waiting for Google to (maybe) push it out to you.
-Will this method work if I have a rooted N1 with unlocked bootloader? No, you'll have to download a modified version of the update file (link above) that will not break your root access.
-It's 'frozen' at a picture of an Android, and arrow, and a box. Is my phone bricked?! No, you're okay. Just be patient as the update is doing it's thing.
