Hi, I clarify the speed thing. JXd s5110 minimal speed is 150 mhz, so have some problems of waking up after sleep. In my Rom I changed this 300 mhz, enough to solve the problem. This guy has changed minimal speed to 600 mhz, that fixes problem too, but in my opinion is not very good for battery, becuae minimal speed is too high. But nothing else, no changes in overclock. This system cannot be overclocked without kernel sources, because JXd has changed the way to establish max speed, so changes cannot be done without kernel sources and making a kernel from scratch I am afraid. No matter that we use setcpu or overlockwidget to try to overlock, because even if system "says" a higher speed, kernel use the speed he is configured for. something that can be seen clearly just making an Antutu Test.
