  2. Hi,

    I am in India and I bought the S3 in the US during my stay there in 2012. I faced the charge full/reduced charge issues and even changed my charger thinking it was me!!
    Last weekend the phone started dying and now, it won’t even start so how do i install the updates? Also, the “where to watch” site will not display content in India!! 🙁

    Please advise, I need my phone as i haven’t backed up in a while.
