Installing CM on LGMS769/P769 - LG Optimus L9 P760, P765, P768, P769

So long story short: Finally got CWM installed on the MS769 from Metro by using some chinese root program to get root, installed busybox, then used the L9 Recovery installer from artas to get CWM on there. So then I try to install bobzhome's P769 CM ROM and met with undesirable results.
Here is CWM installed by the L9 Recovery Installer v1.5:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The rom I'm trying to install:
The "This package is for "p769,p760,u2" devices; this is a "p940" error
This most certainly not a p940! So I suspect CWM is a bit outdated. But how can I get the most up to date CWM when I've already used the most up-to-date L9 Recovery Installer? I've tried other flashing programs like flashr and CWM's official rom manager on Google Play but I get met with the dead android picture when trying to boot into the new recovery I flashed.
I also tried opening up the CM ROM and finding the script that does this check and disabled it. But then shortly I get this error regarding setting recursive metadata. I googled "setting recursive metadata" error and folks just say to update CWM. So I guess I gotta really get CWM updated.
Is this a dead end for me? Should I just toss this phone in a pit of lava?

Have you unlocked the bootloader? If not, you can't install CM.
The CWM you've installed is a 2nd-init recovery. You need to unlock the bootloader to install a) a proper recovery, and b) to install ROMs that aren't based on stock

Click to expand...
Click to collapse
Thanks for the response. Alas, I feared the worst. I had that feeling since there were several people saying there's absolutely no way to unlock the bootloader, and that there was even a petition to unlock it.

It can be unlocked, using a 910k cable and plenty of patience.
Until then, you can only run stock ROMs, or modified stock ROMs such as Kumakan or UltraROM. Try them out, they may suit your needs if you don't want to go through the BL unlock process.
