[LG Optimus L9 P760, P765, P768, P769] ReikiDraven:
I know I did this right. I had to have.

The problem is, there seems to be conflicting information in the tutorials, between Carlos's video, animusFL's instructions, Lelus' instructions and the success stories of the people who've successfully unlocked the bootloader.

I can't tell which method to try.

Here's what I've been doing, with the same exact results, every single time;

Started off on v20F. Rooted it, installed CWM, SuperSU and BusyBox. Installed kuma's ROM, debloated it and installed Link2SD, partitioned my SD card and installed all of my apps. I was pretty well satisfied, but I really, really missed CM10.x. It's hard to go back to stock, even with a tricked-out launcher. Plus, I got tired of having to type in a Terminal Emulator script every time I rebooted the phone to overclock it.

So, I decided to try flashing KDZs and to see if I could unlock the bootloader. In the video, the files Carlos is using are not the same ones as the newest links, so that confused me a bit. I didn't have my microSIM card until today, either. I spent five hours last night on this.

First, I followed the video to the letter. Every step. It failed, and probably did because I didn't have a SIM card inserted. I kept trying with just Wifi, with no success, and gave up five hours later after 6 more attempts.

I spent ALL DAY on this today, from 10AM until just now. Probably a total of 11 hours, all said and done.

I had v20B installed, rooted, with BusyBox, CWM and SuperSU when I got my SIM card. Plugged it up, waited 45 minutes, tried to unlock the bootloader, and it failed.

Hard Reset

Flashed to v20F

Rooted with Impactor, manually installed BB, CWM, SSU using the links throughout the tutorials, through the File Manager.

Flashed to v10G

Hard Reset

Flashed to v20B

Then I tried;

Hard Reset

Rooted with Impactor, manually installed BB, CWM, SSU using the links throughout the tutorials, through the File Manager.

Flashed to v10G

Hard Reset

Flashed to v20B

Tried to unlock with adb reboot... failed

I tried at least 9 different variations today.

My most recent was, starting from a failed v20B attempt;

Hard Reset

Flash u and x using the script and the Command Prompt (it actually worked this time)

Checked all the prerequisites (USB Debugging, Show Touches, Install from Unknown Sources, files on the SD card)

Factory Reset

Flashed to v10G

Hard Reset

Flashed to v20B, slipping the 760(11) bin into the install process

Waited an hour and twenty minutes, twenty with just data, an hour with both wifi and data, with a browser window open

Tried to unlock with adb reboot... failed

Is there ANYTHING I could possibly be missing or doing wrong? Any steps I am not performing correctly? I don't want to have to lose the value of this phone and still have to get a new one, but worse, I just don't want there to be a phone I couldn't mod. This will be the first one I ever didn't completely have wide open to me the first day I had it, and that's beyond frustrating.
