How to Install

Pre-Requisite: Have ADB Setup already. If you don’t, please read ADB 4 Dummies.

Download: Recovery-RA-passion-v2.2.1 (37)

Copy recovery-RA-passion-v2.2.1.img to a location where fastboot can find it. Your desktop would be the easiest place for this tutorial.

Open a command prompt or terminal window and cd desktop

Boot your phone into fastboot mode (power on while holding the trackball)

Connect your phone via usb to your pc/mac/linux

type: fastboot devices
(to make sure that fastboot “sees” your phone)

type: fastboot flash recovery recovery-RA-passion-v2.2.1.img
wait about 30 seconds to 1 minute (longer the better to be safe)

type: fastboot reboot recovery
(If that command doesn’t work, just type fastboot reboot. once your phone reboots. Turn it off and boot back up while holding the VOL-DWN Button. This should boot you into the bootloader. Then scroll down with the vol-dwn button to RECOVERY and select it with the power button. Your custom recovery should boot.)

Done.

You can also just install ROM MANAGER from the Market and use it to install Clockworkmod Recovery or Amon RA.

Upgrading your Nexus One Radio is a breeze. I’ve included the newest version.

***Most roms now require the newest radio, especially the MIUI Rom.***

Unlocking the Nexus One bootloader is easy. Google actually wants you to be able to Unlock their phone. Beware of the consequences though as this will void your warranty. Keep in mind if your phone has any HARDWARE damage that was NOT YOUR FAULT, HTC will still replace your phone as long as it’s still under the manufactures warranty.

Instructions:

Make sure you have ADB setup. Read ADB 4 Dummies for instructions. (Most things you’ll be doing with an unlocked Nexus One involve ADB so you might as well have this setup already)

If you Don’t have FASTBOOT you can download it from Downloads section. It should come with the Android SDK.

Extract the version for your computer into the Android SDK /tools folder.

Connect your Nexus One to the computer through USB connection. If your computer asks you to setup drivers, just choose the drivers folder inside the AndroidSDK.

Now open a terminal or command prompt window.

Type: fastboot oem unlock

You’ll notice the screen from the right show up on your phone. Select Yes or No. Yes if you want to unlock your bootloader. No if you decided not to.

Done.

After unlocking your bootloader you’ll want to install a recovery and new ROM. You can do that by installing ROM MANAGER from the Market.
