Installing Froyo (Android 2.2) on Nexus One with third-party firmware

As many have already read , an update for the Nexus One to the latest version of the Android OS Froyo OS, which was announced on Thursday at the Google IO conference , became available yesterday.
All Saturday he excited the minds of the Android community (there were 100 pages of comments on the CDA!), For Engadget and Tehcrunch wrote that they received it, and the rest of the community did not
But by 10 o'clock we managed to find some more lucky ones, with the help of which we managed to get a direct link to the long-awaited update. The problem with him was one he put only on the factory firmware ERE27 with the factory rekoveri. What did not prevent a heap of people to install it, just rolling their phones to the factory state. But I decided not to hurry and not to make unnecessary movements ...

And rightly so. Within an hour and a half after finding the update, the well-known developer PaulOBrien released a full update that can be sewn onto any third-party firmware (CyanogenMod, Modaco, Desire).
Under the cat is a small instruction on how to upgrade your ruled Nexus to Frozen Yogurt (Froyo)

but. Before upgrading, I recommend using Titanium backup to save all user data before upgrading.

1. Copy Paul’s update.zip ( from here ) to the root of your SD Card.
2. Boot into Recover (Home + VolDown, then in the Recovery menu). We strongly recommend the latest versions of Recover from Amon Ra
3. Make a full Nandroid backup (+ ext partition if you use it)
4. Make a complete Wipe: data + cache, Battery Stats and Rotate settings
5. Flash update (Flash zip from Sd card)
6. Reboot.
7. Wait until the radio is updated and will return you to rekoveri again.
8. Reload again.
9. Enjoy 2.2.

Optional: If you want to get root again (for example, to restore your settings using the same Titanium), you also need to flash a small update from cyanogen
Flash: In order to earn a flash, you need to install it from Market- look for the keyword Adobe
