Hello guys! I am really sorry if there are previous posts with the exact same problem but I have tried many things and they did not helped me. I have HTC Desire HD and I thought I updated to JellyBean 4.1.1. (than I found out that I have hacked it and this is custom rom , please do not laugh at me I am new at this and I was happy for my success ) but now I want to return it to the stock rom, because this one makes problems. I would be very happy and greatful if someone could explain me how. Thank you
