    hi,

    I have a Nexus One with Android 2.1 -update1 Build # EPF21B. I am using this in India. I need to find out a couple of things :

    1. How do I find out if my N1 is rooted or not.

    2. Whether my N1 qualifies for a Android 2.2 update ?

    - If no, how do I make it qualify ?

    - If yes, when do I get the update ?

    Any help and info in this regard would be most appreciated.

    Thanks,
    Amit

    1. If you see a lock icon during phone startup (on the x screen), then its rooted.
    2. If you have the stock ROM, you qualify. Date unknown though.

    But really, if you didn't notice the lock yet without having to see a picture, I'm guessing your phone isn't rooted ;)

    Hey guys (Roze and Teknologic), Thanks for that screenshot. I do not get the Lock. This lock comes automatically as soon as you fiddle around, right ?

    Mine is not rooted for sure.

    Thanks,
    Amit

    Well I wouldn't call it fiddling around. You can do some stuff without unlocking the bootloader, but not rooting.
    So the opened lock signifies that your bootloader is unlocked, and any other roms or firmware can be loaded :)

    hi folks,

    I just downloaded this Android 2.2 FRF85 package from http://android.clients.google.com/packages/passion/signed-passion-ota-42745.dc39ca1f.zip.

    Engadget says this package will update any Android Build. As you know I have the EPF21B build.

    I used the steps for manual update

    1. power down
    2. power up with volume down pressed
    3. recovery
    4. volume up + power
    5. apply sdcard:update.zip

    I get the signature verification failed error.

    Why am I getting the god-damned signature error when my phone is not rooted ??

    I have 2 questions : Will the package that I downloaded from the google servers work on the epf21B build ?

    epf21B is the UK/EU model isn't it...I thought FRF85b (newest) is only for the AT&T and TMO model.

    It's only for the US handsets at the moment, I suspect the Euro ones will have a different build for localisation purposes.

    Ps. For what it's worth, I have the padlock on bootup and I get OTA's just fine. Unlocked bootloader isn't the be all and end all (especially if you can turn it off lol), it's down the the recovery you're using.

    If your bootloader is unlocked then you can't fail.

    If the current build is one that doesn't support an update to 2.2, then flash ERE27/ERE54B and upgrade from that instead.

    As far as I know, the update for EPF21B has not been pushed out by Google yet:(

    If you really want to get 2.2, you are going to have to unlock the bootloader (voids warranty) and apply the new build image manually. There are plenty of guides on the net detailing how to do this.

    I got fed up waiting and did this especially after I found out vodafone were going to mess things up in 2.2!

    Its not as scary as it sounds and only took about 20 minutes. Although it wipes your phone, as long as everything is backed up to Googles servers all your settings automatically get re-applied when you set up your gmail account. All my emails, contacts even apps all came back after I upgraded.

    Finally, not all apps can be installed on your SD card as its up to the developer to implement this in their apps.
