Check your build.. you'll have to go ERD79 to ERE27 to FRF50 and FRF72. FRF50 and 72 are Froyo but they are also NOT the final Froyo release for N1. These are test releases however they are signed by Google.. totally legit i.e. stock firmware and bootloader will gladly accept these. stay away if you're on an ATT N1 (or Rogers).

I have the Rogers/ATT N1, build number is EPE54B. So first step is to get ERD79, then ERE27, then FRF50 and FRF72?

The FRF50/FRF72 updates were built for the T-Mobile N1; they will not run on the Rogers/AT&T Nexus One

Why the sequence? And where can I get the final release? (And where check the build?)

The sequence is because Google uses binary diffs for their updates.

The latest release candidate (?) is FRF83. You can download an update.zip from http://android.clients.google.com/packages/passion/signed-pa... (requires updating to FRF50 first).

You can check the build in Settings -> About phone -> Build number.

OK, so I could also install FRF83 directly without going through the updates?

No, FRF83 has been published only as an update from FRF50 (using the link above) or from FRF72 using http://android.clients.google.com/packages/passion/signed-pa....

If you are running the stock Android 2.1 image, you'll receive an over-the-air update whenever Google deems it ready for general release. Or you can update your phone now to FRF50 or 72 and then to 83.

Thanks - so I guess since I have installed some Froyo image before, I will never get a push from Google for the final release anymore?

If you installed one of the Froyo updates direct from Google, then you will continue to receive future updates. If you unlocked your phone and installed a modified or custom image from another source, then that image probably has OTA updating disabled and you will need to apply updates yourself.

If you flash back to a stock image from Google, then I believe you will start receiving OTA updates again.
