Moderators, I was able to resolve the issue before getting a response feel free to lock/delete this thread if necessary. So I attempted to root the LGMS769 (MetroPCS) by following a guide over on XDA (the Lelus Method), I read in another thread that I can use the "modified 11th .bin file" along with our own firmwares .kdz file to achieve root. (I used the wrong .kdz file like a dumbass) Low and behold once I finished the last step and the phone rebooted, instead of getting a rooted phone I am greeted with "Security Error" after the LG logo and the phone won't boot. I tried doing a master reset and that didn't work, I then tried going into "S/W Upgrade" mode and using The LG Mobile Support Tool but it keeps failing at about 15% claiming that the phone isn't connected or something. The guide actually mentions that as being a known issue and the work around was to boot up, set the PC Connection on the phone to "LG Software" mode and flash the firmware... Unfortunately I can't use that same work around since I can't boot up the phone now. Update: I managed to fix the issue, I was using the "Offline fix flash method" at first and that didn't work... using the LGMobile Support Tool normally (where it downloads the firmware and drivers....etc) got my phone working again... its still not rooted but at least I know how to fix it..... time to go Bawlz Deep and try rooting again!
