Hello, I recently decided to downgrade from 4.3 to 4.1.1 (I'm on Telus I747M 4.3) so that I can unlock my phone due to it being impossible while on 4.3. So then I knew that it basically was impossible, until I stumbled upon thishttp://www.androidpit.com/how-to-downgrade-galaxy-s3 So now I'm wondering if this method is possible? Anyone tried it? Telus users?
