[Q] Another Security Error [P769] topic

Hello to all since this is my first post on these forums! And to just say thank you to everyone who will respond to me if I don't say it.

I rooted and installed CWM 6.0.1.8 on my phone about a year ago. I did not unlock the boot loader, because I didn't want to have any custom ROMs on my phone. Now just recently I was looking at android 4.4 and thought that this is a good update for any phone. So, I started to do my research for what to do to flash a ROM. I downloaded CWM 6.0.4.5 on my micro SD card and used "[ROOT]Recovery Tools - Flasher". Now this is where everything goes south...

I went through the app, found the CWM file to flash, and then I got the security error... After researching why this happened it was because of not unlocking the boot loader which was a huge mistake that I forgot to do.

I have searched on here a lot. I found a lot of great and useful information, but I can't try any of the suggestions yet. Not until my computer can recognize my phone. I know before this all happened, I had debugging enabled on my phone. I do not have fastboot installed on my computer anymore (reformatted a long time ago). I do have B2CApp.exe installed so I could try to do a factory reset on my phone. I have installed the driver for the phone from the LG program and from their website.

But like I said before, when I plug in my phone to my computer, the computer does nothing. It doesn't recognize that there is even a device there, but there is power getting to it. How I know is because I took out the battery and "S/W Upgrading" could be enabled.

If I can get past this, I'm 100% positive I can fix it then. If anyone has some sort of useful information about my computer not recognizing my phone, please share it! Also, for context, my computer is a windows 7 x64.

Thank you for your time and your responses!
