I have att i337 4.2.2 ucuamf3 baseband rooted. I would like to upgrade to 4.4.2. I want to have a custom rom that will remove bloatware, increase speed, increase battery life, enable tethering. I want to be able to still use the infrared. I need to use apps like root call blocker and cerberus anti-theft that need root access.
What is the best way to accomplish this?
