Sprint HTC Hero :: Root Failed After Step 15 - Adb Shell

I decided to manually root my phone, initially I had a device come up and everything was really smooth until step 15

1: Code: cd C:android-sdk-windows ools

2: Code:adb devices

If you've been following this guide you will see your phone's serial number. If you get "device not found" error, you either need to make sure you the drivers were properly installed or make sure you enable USB debugging AFTER you connect the USB cable. Continue on once you get the proper phone serial output.

3: Code:adb push asroot2 /data/local/

4: Code:adb shell

5: Code:chmod 0755 /data/local/asroot2

6: Code:/data/local/asroot2 /system/bin/sh You should see an output that says: $ /data/local/asroot2 /system/bin/sh [+] Using newer pope_inode_info layout
Opening: /proc/857/fd/3
SUCCESS: Enjoy the shell.
#Now for a few last commands.

7: Code:mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

8: Code:cd /system/bin

9: Code:cat sh > su

10: Code:chmod 4755 su
You are now officially rooted. A few more steps and you will have flashed the recovery image.

11: Code:exit

12: Code:exit

13: Code:adb push recovery-RA-heroc-v1.5.2.img /sdcard Pushing is equivalent of copy the file to the root of your sdcard. By the time you finished reading this it should be done. You'll know its done because the ouput will say something like transferred X bytes in X secs.

14: Code:adb shell reboot This will cause the phone to restart automatically. Wait till it is fully booted to continue.

15: Code:adb shell Now I receive the following Error: error: device not found

I tried to reboot the phone but there was not change.

I tried the following
C:android-sdk-windows ools>adb kill-server

C:android-sdk-windows ools>adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached

I was hoping to get my original device listed, but I still have nothing.
