FroYo

It took what for most Nexus One owners seemed to be a lifetime, but we now have the download location for Android 2.2 (Froyo). Here's what you need to do to flash it to your phone:

Update: Yeah. Hang on a sec guys. Sorry bout that.

We're doing ours right now, so stand buy, and sound of if you're having fun.

Update #2: You can install a FroYo nandroid backup (courtesy of scepterr at the CM irc channel) as long as you're running ERE27

  1. Backup everything via nandroid (this isn't a rooted ROM)
  2. download ERE27 Here
  3. download the nandroid version of FroYo Here
  4. reboot into custom recovery
  5. wipe all data
  6. flash the ERE27 update.zip file from step 2
  7. When finished, preform a nandroid restore using the nandroid image you downloaded in step 3
  8. reboot
  9. enjoy some FroYo

I wonder if the update.zip file will work on a Droid?

URPREY says:

Nope.

gregg37 says:

Thanks! Updating...

Darkshneider says:

Gbhil, can any of this be backported to the Hero?

gbhil#AC says:

possibly. I've got it loaded and will be fooling with it all weekend lol

Darkshneider says:

Im willing to sacrifice my phone :D.

Lorin Bute says:

Can't wait for you to report back. I'm ready to do it if you report success.

Beatnik says:

I followed this tutorial, easier than the posted above.
http://sillybanana.net/2010/05/23/manually-upgrading-the-nexus-one-from-...
I think it is the best out there, worked PERFECT for me on my T-Mob NON-rooted Nexus 1, it is Faster than ever

Do it have full flash in the browser?

gregg37 says:

"If you're rooted and ROM'd, make sure you're running the stock recovery module"

Need help going back to this... any ideas?

How fast is the phone now with this update?

Lorin Bute says:

Should we worry about future updates in case we install this version?

Lorin Bute says:

Users have reported that Move to SD Card option is grayed out. Please confirm, because this is the sole reason i want to update. Thanks.

uansari1 says:

As has been posted on a couple other sites.. Apps2SD has to be enabled by the app developer. They have to allow their app to give you the option to move/install to SD.

icebike says:

We need a hack for that.
Non essential things should/could go over to the SD card whether or not the developer has got around to it or not.

Skrattande says:

still sat with bootscreen getting worried here

Lorin Bute says:

T-MO or ATT Version? It works only for T-MO now. A patched version is on the way.

GarlsOne says:

Will this work for the AT&T version? My build number is EPE54B. The file name lists ...from-ERE27...

Lorin Bute says:

you need the patched version which is being uploaded now. wait 5 minutes.

GarlsOne says:

I think i am going to go and do a very odd thing instead of waiting. I am going to go outside and play for a while. :) I will check in a few hours from now and hopefully all you guys will have this down and under control.

And thanks for all the help!

j0npau1 says:

Can this process be used to revert from a mod, say for whenever the next update comes? Is there an easier way to do that? Thank you :)

Skrattande says:

Okey Dokey Nexus one just updated running sweet on 2.2 like the extra 3D on the scrolling menu

DVNO says:

some people over at phandroid.com are saying this is for real and working great. Something about androidcentral though, i feel like these guys are more legit. I'll wait and see what they say.....

Lorin Bute says:

ETA on ATT patched version is 20 minutes, so hang tight.

falconeight says:

They were not kidding when they said it was faster. My N1 is blazin fast with this update.

j0npau1 says:

Same here. I'm getting chills. It's even snappier than before.

cesarb says:

Just installed on my virgin N1. Everything went flawlesly.

mbranscum says:

Why does the ATT version have to be "patched?" Will this be the same as the OTA update when it arrives?

Lorin Bute says:

The build number is different so the update needs to bypass that.

falconeight says:

I like how smooth the scrolling is and it looks way cleaner. The twitter widget is very nice also.

Hey guys when i click the update.zip file on the last step it says verification error !!, please help
thank you

Lorin Bute says:

ATT?

mbranscum says:

I get an error too. I am using an ATT stock rom. Iss yours an ATT or TMobile version?

mine is Tmobile :(

Lorin Bute says:

For ATT please wait. An updated version is coming. Your build number is different from the one on T-MO so the new version needs to be able to bypass that. Its almost ready.

mbranscum says:

OK...thanks Lorin. Theres no change of this patch rom bricking my $521 phone is there? :)

snowman2149 says:

Lorin Bute says:

Phill are you there? Please update us!

JOHNGAETANO says:

I have a rooted Nexus One AT&T.
Can I simply load the RA Recovery and flash the update.zip file?
Or do I need to go back to the stock recovery?
If I have to go back to stock recovery, HOW do I do that?

I can't seem to get a clear on these questions.

abocornwall says:

I can't wait until 2014 when our droids get it and we don't even need it yeah. .. lol

Krak-a-Lakn says:

You need to download Flash from the Market (at least that is what I have been reading).

DVNO says:

Yes you need to download flash from the market. Just search for adobe and you will see it. Ok, gotta get back to some froyo, mm mmmm mmm this is good!!!!

cesarb says:

Now that i got it to install does the flash come installed already? Or do i have to install it somehow?

snowman2149 says:

hey brothas dont extract the file just copy to N1 and rename to update

Lorin Bute says:

Just tried and i get that error. On T-MO, the correct build number. Strange!

serpico says:

Does the update delete everything on the phone? Do I need to download every app again and sync my calendar, contacts, etc? I read that some carrier update did that to someone's android phone from 1.5/1.6 to 2.1.

how do u install nandroid backup ??

Lorin Bute says:

Re-downloaded the update and trying again!

gregg37 says:

Still need "stock recovery module" for this new way, Phil?

If so, I am lost.

gbhil#AC says:

Negative. This method works with Amon-Ra or Clockwork ;)

Lorin Bute says:

Update finished and......froyo booted :D

dude please help me too, how u use nandriod back up i am little new to android i had windows before
thank you

Lorin Bute says:

I don't know how to use it. I never used it. I had stock N1 T-MO. Btw, it keeps all the settings and apps installed. Nothings is lost, including the app data is still there.

jzarowitz says:

so a virgin n1 on att is sol? boo.

DVNO says:

Wow...blazing fast. So glad i did this. Love this N1 even more now, if that is even possible ;)

gregg37 says:

Link in Step 3 is dead.

gbhil#AC says:

will re-up

ETA: 9 minutes. Bandwidth is sloooow toady ;)

gregg37 says:

hehe. thanks

Anas says:

Link in step 3 is dead

Link is now live again. Longest 9 minutes ever lol

Lorin Bute says:

Damn, getting tons of force closes in apps like easy money, xiia live and others. Really pissed off because i use these on a daily basis.

BDHN1 says:

Is anyone having problems with some of their apps. I can't get get Dolphin Browser to work any longer, it force closes every time I touch the address box in the app. Also, a game I had (Papa Stacker, paid version) won't show up in the matketplace now. I'd like to think it's because it's getting approval of a new version to store itself on the SD Card, but that seems like wishful thinking.

falconeight says:

I am typing this on my wifi only iPad tethered to my N1 running 2.2 froyo. YES

falconeight says:

Too bad for people paying $30.00 and extra money for iPad 3G.

malibumac says:

Okay, this is great and all, but someone needs to make a version for the DROID!!!

inhuman says:

does it free up more ram?

masch says:

How can I use FM radio??

Glorishan says:

Updated my stock TMO N1. Only one issue so far - the Dolphin Browser HD crashes every time I try to click in the URL box to go to a new site. I'm posting this from my computer which is using the new Android Wifi Hotspot. The hotspot took me about 4 seconds to set up. I'm not yet sure how many simultaneous connections you can have. The speed is not blazing fast (.43Mbps download, .33Mbps upload), but it's reasonable for sure.

Glorishan says:

Voice dialing over bluetooth works, but isn't as good as on a Blackberry. You have to say "call" to call a contact, or "dial" to call a number. However, when trying to reach a contact it assumes it isn't possible to make a mistake, and it will call somebody even if you say "call bla bla bla."

The stock keyboard has an improvement. When typing a message, after you hit a space it gives you the option of selecting ! ? , @ or _ where it would normally give you word suggestions, negating the need to go into the symbol menu as often.

In SMS, it word wraps around contact photos.

In the call log, it now groups logs from individuals and gives the option of expanding.

Flash works well, but hulu is blocked.

Will add more as I keep testing.

Glorishan says:

Got a 92 on the Acid3 acid test, 2.1 gave a 93.

Android now shows you the eight most recently opened applications instead of six when holding the home key.

No music available for download via the Marketplace thus far.

Very simple to set automatic updates for programs in the marketplace.

I don't believe the desktop application is available for streaming music to Froyo yet.

manningfan10 says:

Anyone try this on moto droid?

JtothaR says:

Dont see how to backup the phone without rooting, but this is supposed to work on non rooted phones?

gbhil#AC says:

On a non rooted phone, just download the OTA, rename it to update.zip and flash it from stock recovery.

JtothaR says:

Tried that. Just says verifying file then aborts.

stalker says:

Hello guys,

Just have a few question. I am located in india and have a nexus one non-rooted and unlocked version. I want froyo update on it but I am not able to get OTA update though update option. I’ve few question.

after installing this update manually, does my N1 converted to non-rooted?
what about warranty?
what is the difference between this update and the public update when it will be available?
can I switch back to the 2.1 after installing this upgrade ?
and what happen after dialing *#*#2432546#*# ? is it harmful?

Tom S. says:

Can someone update this to relect the AT&T version? I know the link that is given is or AT&T, but how about where to get the EPE54B version? Steps, 2 &6?

alacran says:

Hi guys, any luck with the AT&T stock model? I dont wanna root the phone I got the EPE54B, It shouldnt take long before there is one out ? Or is there something missing and not posted? thanks

AdamCollet says:

200+MB free RAM!!! I'm completely astounded. That's roughly a 160MB increase for me. Incredible.

lolobabes says:
