I get error while trying to start phone with power on, or even into recovery/download mode. "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help." This happened after trying to flash CM10 through ROM manager app. I keep reading try to flash via Odin but I cant get into download mode for my phone to even show up on Odin. Help?
