All my thanks to Ricardo Cerqueira. The following tutorial is made due to the efforts of the developer aremcee and the efforts of some others like aiamuzz, varoon88.

This works with LG Optimus Pro c660 and c660h
BE SURE YOUR DEVICE IS ROOTED / BACKUP ALL YOUR IMPORTANT INFORMATION STORED IN THE PHONE.

Up to this moment the most functional build is build 11:

READ THE WHOLE POST FIRST.
IT HAS:

1) NORMAL PROCEDURE TO FLASH THE RECOVERY (aiamuzz)
2) ANOTHER PROCEDURE IN CASE THE FIRST DIDN'T WORK
3) INSTALLING CYANOGENMOD7

1) FLASHING THE RECOVERY (NORMAL PROCEDURE)

1. Install ROM Manager from the market.
2. Open ROM Manager choose 'Flash ClockworkMod Recovery'
3. Choose your device (Optimus Pro)
4. The recovery file is downloaded and will be installed
(wait for a confirmation message saying CWM recovery flashed/installed successfully)
5. Choose Reboot into Recovery !!!

If your phone boots to a terminal/dos like screen with various option which can be navigated(move up and down through the options) using the Vol Up and Vol Dn buttons and selected using the Power button.

You have successfully installed the ClockworkMod Recovery !!!

Please continue from 2) INSTALLING CYANOGENMOD 7 if this was succesful, if not, try 1B

1B) PROCEDURE TO FLASH THE RECOVERY IF "1" DIDN'T WORK AND YOU GOT A FACTORY RESET:

You will need:

- ADB (SDK installed). If you don't know about this serach for some tutorials.

- Have the path to ADB Set. (On Windows, right-click on My Computer, and select Properties. Under the Advanced tab, hit the Environment Variables button, and in the dialog that comes up, double-click on Path (under System Variables). Add the full path to the tools/ and platform-tools/ directories to the path or wherever yo have SDK)

- ROM Manager installed in your c660 or c660h

- To have the recovery file in your SD Card. http://www.mediafire.com/?058a079jkx32mf4

- The flash_image provided here: http://www.mediafire.com/?1ud0kmd631eeugb

- CM7 nightly (last build) http://download.cyanogenmod.com/?device=c660

- Google apps for CM7. http://wiki.cyanogenmod.com/index.php?title=Latest_Version/Google_Apps
Steps:

1.- Connect your device by USB (with the debugging mode activated) in order to work with adb.

2.- Open CMD in windows and type "adb devices" (without quotation marks) and you will see a list of attached devices where you have to se a number and a device; if there's nothing on the list your device is not being recognized.

3.- If all it's okay, download the flash_image file, for example I left it in C: . Then, in the cmd type:
Code:
<br />
adb push [URL=C:/flash_image]C:/flash_image[/URL] /data/local/<br />
As I have the file in C:/ I typed C:/flash_image, you have to type where you have the file.

4.- If that's successful, type the following:
Code:
<br />
adb shell<br />
su<br />
chmod 755 /data/local/flash_image<br />
/data/local/flash_image recovery /mnt/sdcard/recovery-clockwork-5.0.2.7-c660.img<br />
With this you are going to flash the recovery by ADB and you will receive something like this:
Code:
<br />
flashing recovery from /mnt/sdcard/recovery-clockwork-5.0.2.7-c660.img<br />

5.- After this, disconnect your phone from the computer and go to the app ROM Manager. Try to Backup your own ROM. The device will be rebooted in the recovery, if this works and the process is completed you're finishing. (Don't worry for the "E: bad boot message" error, it's normal). If you get your phone with a factory reset you did something wrong.

---

2) INSTALLING CYANOGENMOD 7

1.- In Rom Manager, install from the SD card the last build of CM7 nightly. The phone will be rebooted and it will install, after this you'll get the rom installed and working.

2.- Finally install the CM7 Google Apps provided in the website posted above using Rom manager just like you installed the Rom.

If you have any problem post it.
