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

How to update Android 2.2 Froyo to your Nexus One, the manual way

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

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

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.

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.

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.

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!

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 :)

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.....

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.

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.

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!!!!

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

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.

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.

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

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.

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.

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.

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.

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.

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

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.

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?

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?

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
