I recently bought a used phone HTC Hero200 it had gingerbread on it. I had to flash it to a stock rom and then flashed it back but now i can't access android market to download new apps. Please help. i have changed the settings in order to allow other apps. everytime i try to go into market app it says you must add an account to this device to continue do you want to add one now? I hit yes and then it boots me out of the app. any suggestions?
