Android 2.2 Froyo

The wait for Froyo is over, folks -- well, at least for those of you with the Google Nexus One. The Android 2.2  update that was pushed out in the afternoon -- FRF85B -- indeed is the official release. And just like we said they would, Google announced the update today:

Starting today, Nexus One users will begin to receive the Android 2.2 (codenamed Froyo) over-the-air software update on their phones. This update provides some great new features including support for making your handset a portable hotspot and support for Adobe Flash within the browser. For a complete list of everything we’ve included in Android 2.2, please see the Android 2.2 Platform Highlights.

In order to access the update, you will receive a message on your phone's notification bar. Just download the update, wait for it to install, and you should be all set. This update will be rolled out gradually to phones - and most users will receive the notification by the end of the week . We hope you enjoy these new features.

If you're running a custom ROM, you might not get the update pushed to you, so head to the nearest forums (oh, look, here are some) to find the manual updates. [Google]

Latest Froyo build for the Nexus One is the official Android 2.2 update


Sprint approves updates quickly. Former Pre owners will know that we got updates like a month before Verizon got their updates.

HTC... we'll see about them. Hopefully they take care of their high end devices now.

stock N1 manually updated to FRF50 when it came out but didnt update on FRF72 – when I woke up just an hour ago I got the OTA update for FRF85B (1.9MB), am in the Philippines… ty Google

yay.. finally it arrived. I've installed it. It's working fine. But there is no significant changes found from build FRF83 to FRF85.

I bought Nexus in the USA but I live in Europe and I want to know if mine will get updated on 2.2 over the air as well?

I got an iPhone 4, and was going to get a micro sim adapter once Froyo came out.

Just wanting to know if the update will be pushed to my phone even though I don't have a sim card in it.

Just as a side note: Does anyone find hitting the System Update button very unsatisfying? You hit it and it IMMEDIATELY pops up telling you your system is up to date. No icon showing it's thinking or connecting to google servers. Just an immediate no. I wish they'd throw in a little animation to at least give me the impression that it tried to find an update:)

I actually completely agree. It makes you think that it doesn't actually work! Frustrating when your waiting for an update.

all that button does is search for an available update on your SD card. When you get the OTA, you have the option of updating immediately or downloading and installing later. If you choose the latter option, you must go to the System Updates section in order to install it. If you have not received the OTA, going to the System Updates section does nothing for you.

Hey guys,

The download for 2.2 was done this morning as soon as I turned on my phone. The problem is, the night before I had downloaded from the link provided and named that file "". So I guess the download wouldn't overwrite what was there. Does this mean that I won't get another official notice of an update? Do I now have to manually do it?

Manually updated using the instructions on the engadget post.

using Rogers Nexus One (originally EPE54B build). When I got to the '!' screen hit volume up+down+power to get it to take the update (well get the option to apply the update).

I tried doing the Market 'Update All' but as it kept choking and causing a force quit. I have a feeling this was because I had put off updating apps since Google I/O so there was 37 apps to update plus another 6 that had to be done manually because of permission changes.

I noticed that the setting widget (the row of 5 with the green bars on the bottom), the brightness option now goes OFF > Medium > Full > Auto (Auto being the new option there).

Also noticed the main message screen is white instead of black.

It seems that some of my applications seem to be randomly starting up (at least according to my task manager). But not certain if they are just checking for updates or what.

Was also a little confused about how to adjust the settings for flash in the browser, but figured that out (just browser plug-in prompt to run check/uncheck).

Overall feels a lot smoother in general and the browser definitely is snappier.

great people on at&t have it.. people in the Phillipines have it... and I am still waiting with my Nexus on T-mo :(

They should allow manual triggering of the OTA.

decyph: market was down this morning... may be that's part of the problem.

To get the checkin dial the following on the phone keypad. No need to hit send. *#*#checkin#*#*

Wait a few seconds and you will get an alert saying checkin success.

I have done this many times and have not gotten my OTA notification, so I am not sure what the point is. It did seem to cause app update notifications to arrive right after the checkin.


Hey guys i am new to all this, how do I manually download Froyo to my phone I went to the engadget website and downloaded the zip file but I don't know what to do after that.Can someone give me a hand.

Download the Android 2.2 firmware for the Nexus One
Rename the file and copy it to your microSD card via USB. [Note: make sure the file is named and not]
Power down your Nexus One
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. Scroll down to “recovery” and press the “Power” button.
When you see the triangle with an exclamation point symbol, press the “Power” and “Volume Up” buttons at the same time.
From the menu that appears, select “Apply”
When the screen displays “Install from sdcard complete” select “reboot system now” and wait for the phone to power back up.

If you have a rooted nexus one can you install this build of froyo, or do you have to wait until a rooted version is released?

Thank You

I’m running FRF72. Can I upgrade to the final by just using Google’s latest published zip, i.e., renaming it to and running it? To be clear: I'm wondering if I can update without dropping back to a previous build.

I doubt it. It clearly says in the file name:

signed-passion-FRF85B-from-EPE54B.75b107d6. So, only from the EPE54B build.

where on 2.2 is the settings to change the trackball notification colors? I can't find it. Also I did the manual update on my AT&T N1, can I delete the file from my SD card?

Trackball colors are changed by the app that sends the notification, or an app like Blink or Trackball alerts (blink works, Trackball alerts not for froyo quite yet)

Yes you can delete the zip file.

I find it amazing how many people install pre updates and root their phone and not have any clue what they are doing then are completely impatient for official updates.

I read my share and found out what I was doing before unlocking and rooting, so i knew that installing these pre-release builds was silly. When the official was going ota i rolled back to an nandroid backup(stock recovery, and all other stock images) then ran the checkin and nothing so applied the update via stock recovery and a full froyo with no problems coming from a recovery image i made of a stock 2.1 build.

"but let's hope for a better deployment than the update this morning."

I dont even know what the above means, the deployment was fine....

I had no problems and am loving a full release update. still cant wait till cm6 is released though, i miss the little tweaks that were in there.
