Thanks to Drew for this method:
Here are the steps necessary to flash the stock v9 recovery image.
platform-tools.zip
1) Above is a file called "platform-tools.zip"
2) Inside that zip file is a folder called "platform-tools"
3) Copy that folder to the desktop
4) Inside the folder you copied to the desktop, there is a file called "v9recovery.img"
5) Copy v9recovery.img to your sdcard
6) Turn OFF USB Storage
7) Open a command prompt (in Windows XP this is Start->Run then type "cmd" (without quotes) then hit enter
8) In the command prompt, type "cd" (without quotes)
9) Drag the platform-tools FOLDER from the desktop to the command prompt
10) Make absolutely sure there is a single space between "cd" and the rest
11) Hit enter
12) Type "dir" followed by hitting enter
13) One of the files listed should be adb.exe
14) Type "adb shell" and hit enter
15) When it connects, type "su" if it shows a dollar sign ($) and not a pound(#)
16) Type "cd /sdcard" and hit enter
17) Type "ls" and hit enter (that's a lowercase L followed by a lowercase S)
18) One of the files listed should be v9recovery.img
19) Type "flash_image recovery /sdcard/v9recovery.img" and hit enter
20) When that finishes, type "reboot recovery" and hit enter
Should reboot into LG stock v9 recovery.
