Thanks for the heads up guys! OP updated with proper download links and instructions. We're good to go!
Just tried using this method, got the following:
[*] Rooting phone...
[+] This may take a few minutes.
[-] Faliure.
It's entirely possible I may be misunderstanding the process. Here's my current situation: Spent a couple hours yesterday fighting my phone to get the Jellybean update installed (I might not have worried about it since it isn't adding features I really have an interest in, but for some reason LG decided it would be a fantastic idea to have the phone trigger an alarm as a reminder to update the firmware. This woke me up several times, because the reminder kept occuring between 11pm and 1 am, which is utterly baffling). I had ICS rooted, so I couldn't get the Jellybean update installed without wiping the phone and reinstalling from a cab (I ended up using the KDZ method with the converted Jellybean cab). So now my phone is freshly Jellybean'ed with a few of my apps reinstalled, but since it's not rooted, the app backups I did with Titanium are inaccessible, so some of my apps (especially some games with local progress/savedata) have to wait for root
The steps I took were to download the linked motochopper package, unpack it onto my computer, connect my phone in Internet Connection (ethernet) mode with US debugging, then execute the contained run.bat. After it finished with the failure message, I checked Titanium just in case it actually succeeded, but Titanium detected no root access. I saw in another thread talk of needing a new Recovery, so I wondered if this was the element I was missing.
Any help would be greatly appreciated
UPDATE: Apparently this was my own fault, I skipped something I shouldn't have. I've used this particular computer in the past to root my Spec2, so I assumed I had all the drivers still installed and ready to go, but that wasn't the case. This time, when I connected my phone and it popped up on the computer the installation folder with the LG Bootstrapper and such, I went ahead with the install for that. It seemed to fail on part of it, saying that the MTP drivers weren't installed, but after that it launched the LG Update Assistant installer, and I let that run. Once that finished, the phone reconnected and Windows indicated new successful driver installations, so I ran Motochopper again. It appeared to succeed, and when the phone finished rebooting, I got a Superuser prompt and was able to run Titanium properly
Hopefully my stumbling about will help someone else
