[How-To] Manually Update Nexus One to Android 2.2 FRF91 (7/1/2010)

I just got my Nexus One (AT&T version) off ebay (first Android device I've owned) and I realized it was already rooted. It currently has FRF83 installed and has a custom recovery (RA-Nexus-v1.7.0.1). I've been attempting to update to FRF91 with no avail. I tried using the update listed for custom recoveries from this thread [ROM] Froyo FRF91 Stock with optional root - HTCPedia.com forums and it even says it installed successfully with no errors but when I reboot and check the build its still on FRF83.
Any help for this noob Android user would be very apprechiated :)

Here's a thorough run through of everything that FroYo brings:

Android 2.2 Froyo: everything you ever wanted to know -- Engadget

Unfortunately, for now, this method is only for stock users of the "T-Mobile" version of the N1. If you are rooted and have an unlocked bootloader, I have special instructions below.

There're are a few ways to end up at FRF83. If you're on 2.1, go to FRF50, then straight to FRF83.

If you've already flashed 50, then 72, take the file from 72 to 83.

Manual Update Instructions

1. Download file from the following link(s):

From 2.1 EPE54B to 2.2 FRF85B

From 2.2 FRF85B to 2.2 FRF91

From FRF50 to FRF72

From FRF50 to FRF83

From FRF72 to FRF83

If you don't know your build number, go to settings, about phone

2. Rename the file to update.zip

3. Note that if you're using Windows and don't have "show file extensions" turned on in the file explorer you won't see a .zip. Just rename it to "update" (no quotes, of course) because it's already a zipped file.

4. Copy the update.zip file onto the root of your microSD card (that means not in any folders)

5. With your Nexus One off, hold down the trackball and press the power button.

6. You'll be booted into a white screen with three Android robots on skateboards. Select "Bootloader."

7. On the next screen, select "Recovery."

8. Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.

9. Now press the power button and volume up button at the same time. It could take a couple of tries.

10. Now (using the trackball this time) choose "Apply sdcard:update.zip" and let things run their course.
