I had my phone flashed with clockwork recovery and CM7 but after using an external antenna the internal antenna on my Optimus V stopped working. I was trying to make it as stock as possible so I could exchange since that's what the VM rep said I should do. In the process I flashed a stock ROM and ended up putting my info in so I recovered using the option under the privacy settings. I am now only able to boot to clock work recovery and I am able to obtain a adb shell. I am not able to do su and I am unsure of what I should do next.
