How-to Update Your Nexus One to Froyo… without Reverting
You’ve got a Nexus one, you’ve rooted it, and you’re running CyanogenMod (or some other custom ROM), and you were hesitant to flash the stock ROM and recovery image to be able to install the Froyo Android 2.2 update. I don’t blame you!
If you waited, you’re in luck! The developer community has again pulled together and released a version that you can flash from your recovery ROM (Clockwork, RA, etc.).
This isn’t the stock Froyo update, however. A few extra bells and whistles have been added (specifically SuperUser support and related apps).
Where is Cyanogen in all this?
Steve Kondik has committed to update CyanogenMod ROM to Android 2.2, but he’s waiting for the source code to hit the AOSP repository before he builds support into his ROMs.
So, whether you have a stock Nexus One or an N1 running a custom ROM, you can now quickly and easily flash Froyo.
