• PC running Ubuntu Linux. The method has been tested to work on Ubuntu 10.10.
• Nexus One running Android 2.2.1 Froyo.
• ADB installed and working on your computer.
• The required Nexus One Softroot files.

1. Download the Nexus One Softroot files from the link given above and extract the contents of the tar file to the same folder where you have ADB.
2. Launch terminal and navigate to the folder where you have ADB and these files.
3. Enter the following terminal commands:

   sudo ./adb push psneuter /data/local/tmp/psneuter
   sudo ./adb push busybox /data/local/tmp/busybox
   sudo ./adb push su /data/local/tmp/su
   sudo ./adb shell chmod 755 /data/local/tmp/psneuter
   sudo ./adb shell chmod 755 /data/local/tmp/busybox
   sudo ./adb shell chmod 755 /data/local/tmp/su
   sudo ./adb shell
   
   cd /data/local/tmp./psneuter
   
   sudo ./adb shell

4. You should now get the # prompt, indicating that rooting has been successful. To confirm this further, enter the command ‘id’ (without the quotes). You should see get ‘uid=0(root) gid=0(root)’ as the response, confirming that you now have root access.
5. There are a few steps still left to make this root permanent. Continue by entering these commands:

   mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
   cd /data/local/tmp
   ./busybox cp busybox /system/bin
   chmod 4755 /system/bin/busybox
   busybox cp su /system/bin
   chmod 4755 /system/bin/su
   exit
   
   exit

6. You should now set your /system partition back to read-only before you get ready to wind up. Simply enter these terminal commands:

   sudo ./adb shell
   su
   mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
   exit
   exit

7. Lastly, you must install the SuperUser app. The latest version available from the Android Market is recommended and should work perfectly. Once it is installed, you’re all done.
