Android 4.0 Brush the Basics


Recommended Posts

What are root? Root corresponds to the Windows administrator privileges root privileges by default does not allow users to use, because users may misuse or run into malware to damage the device file system root privileges.


So why do you want to root it? Root too the NexusOne can do more things, turn the wall more convenient, running Ubuntu, brush machine.


Three, to see how the success of root? Go AndroidMarket find a TerminalEmulator download, su Enter the enter TerminalEmulator type, if the command prompt at the beginning from $ into the # represents the root. Alternative methods: Enter, type su, then type whoami Enter, if you display the uid0 then represents the root.


Fourth, what is "unlock the bootloader? The bootloader once the unlock will no longer be the warranty, but allows you more convenient to install third-party system.


V. unlock bootloader phenomenon? Sign the bottom of the screen there is a boot unlock.


Sixth, What is the Recovery? Interpreter over the "recovery", is a just brush machine (and other auxiliary brush machine's function) of a procedure under normal circumstances Brush are using the Recovery completed, the current common Recovery There are ClockworkRecovery and AmonRA, I personally proposed use the Amon RA1.8.0.1 or more version, simple operation.


What is Radio? Responsible for the processing of communication signals in a range of software, the new version of Radio is generally less battery consumption, a stronger signal, better voice quality and network speed. The Android2.2 need 4.06 more than the radio before can work CyanogenMod5.0.8 although not Android2.2 but also needs to 4.0.6, Radio to work.


What is the Kernel? Kernel, Android system running Linux, Linux-based rely on the kernel to do all the underlying data exchange and scheduling. The new version of the kernel is generally the speed of system improvements and new features, there is a different power management options that may save the battery. Not all of the kernel is can be used on all systems, such as Pershot do Kernel is only applicable to the system CM and Enomther.


The difference between nine-core power management AVS and SVS? The NexusOne CPU itself to support a way of adjusting the voltage, the required voltage is dynamically adjusted according to the CPU's operation, this model is the AVS. But the the NexusOne original system does not support this feature, because this feature is not rigorously tested. The most common AVS kernel is IntersectRaven production, the AVS kernel is relatively stable in most of the Nexus One. The default power management is the SVS, which is a static voltage is set to static regulation voltage according to the operating frequency of the CPU load. (In general, the AVS than SVS save battery)



Android 4.0 Brush steps:

1, unlock Bootloader

2, brush a third-party Recovery

3, the Recovery, the first brush Radio (Note version, Android2.2 Radio, must be 4.06 or more)

4, Recovery, brush system

5 (if the system does not comes with Google's software) the brush GoogleAppsAddon (mainly applicable to CyanogenMod)

The order of 6 (optional) Recovery, brush core radio, system, googleapps with kernel must not be arbitrarily adjusted, or likely to cause the system will not boot.
