Installing Android 2.2 "Froyo" On the Nexus One

gjt writes "I awoke this morning to see TechCrunch's MG Siegler post what appeared to be the first news of Froyo's availability. I frantically went to my phone's settings and tried to check for an update -oe but no luck. Then I went to xda-developers.com and sure enough there was a very long thread (now over 132 pages) of fellow eager beavers waiting for release (and trying to figure out how to get it). Several hours went by waiting for a semi-technical user to get the update and check the Android logs for the download location. It turns out you can get it straight from Google. With the information scattered around in different places I decided to consolidate the How-To into a single post." Note: According to attached comments, and to the TechCrunch story, it seems this is a staggered rollout, so not every Android owner may be able to try it out yet.

It's pretty good actually - there's a setting which lets you turn off plugins unless you click on them. Which means you don't get flash unless you really want it.

I have the Nexus One, and the attempt to apply this update has my phone apparently complaining that the fingerprint of the file doesn't match.

assert failed: file_getprop("/system/build.prop", "ro.build.fingerpting") == "google/passion/passion/mahimahi:2.1-update1/ERE27/24178:user/release-keys" || file_getprop("/system/build.prop", "ro.build.fingerprint") == "google/passion/mahimahi:2.2/FRF50/38042:user/release-keys"
E:Error in /sdcard/update.zip

Fortunately it's not trying to apply the update, and hasn't done anything unfortunate like brick my phone.

I re-downloaded the file and tried it a second time just to be sure something hadn't gone wrong with the download and copy to my SD card.

Replying to myself, it seems like there are different builds for different submodels of the phone. For example the AT&T compatible phone (like I have) doesn't use the same update file as the T-Mobile compatible phone. Haven't had luck finding the EPE54B download yet.

I'll wait until Cyanogen adds it into his

Remember if your rooted and update to this, you'll probably have to re root it and install a new rom all over again to get all your rooted programs working. Unless you know how to use adb and the other utils to picjk apart features very well, You probably should just wait till your prefered flavor rom has the new features integrated. It shouldn't take long.

This is what Titanium Backup is for. Back up your apps (with the Google Market information) to your SD card, optionally back the SD card up somewhere safe, install the new ROM, re-root, and then restore your apps.

I think the better test will really be for when Froyo gets ported to the G1 and seeing how Flash performs then

Have you heard definitively that Froyo will be ported to the G1? I was under the impression that Froyo and even Eclair are too big to fit on the G1. I'd love to be proven wrong -- I have two old G1s sitting in a drawer and would love to put Froyo on them. Froyo arrived on my N1 last night, and I'm very happy with it so far; there are lots of nice incremental improvements. But as far as I know, nobody is working on shrinking Froyo down enough to fit the G1.
