I wonder if I can use the International RUU to flash?
I live in Brazil, my AT & T HTC One came with the factory rom 4.1.2 and can not update it, I would update it to 4.4.2 KitKat. So I will flash 4.4.2 for htc international, to avoid AT & T. applications
I do not like the AT & T screen when I start the phone.
sorry for my english ...
