I have bought new HTC Amaze one week back from Karachi, Pakistan under Brightex Warranty. I m unable to update it's android version i-e 2.3.4 to 4.0 ICS. I search about this issue on internet and found that Non T-Mobile Amaze are not yet receiving updates. But there were some link to install Manual updates. I m in a doubt that If I do so, will my warranty be void? Please help
