Hello everyone, I am new to posting threads so I will start very simple. I have an lg Optimus S that was rooted and then my son took over the phone. Now when you turn the phone on it goes right into android system recovery, when using the usb cable to hook to the computer, the computer doesn't recognize it. I have a sd reader and was trying to zip files onto the sd card and then putting into the phone and all I got was zip verification and signature not recognized. I have read all the other posts and nothing works, so I'm hoping that someone with a lot more knowledge can help me. Thank you very much
