You can take a look at the/init. RC fragment in the root directory of the Android system:

After some phone root, this prompt will appear when using ADB root.The reason is root is not thorough.After the ADB shell enters the interface, SU only enters the #.After this, you can use the root function.Notice that at this point the exit is first returned to $ and then the shell is exited.In this case, the contents of the ADB pull system folder are inconvenient.For example, what's under Dev.The solution is to install ADBD on a phone that is not ro

Through the introduction of the Android root cracking principle analysis, we should understand that the ultimate goal of the root cracking process is to replace the SU program in the system. But to replace the system in the SU program itself is the need for root authority, how to root in the process to obtain root acc

The device has the adbd service program running in the background to provide services for the adb program of the development machine, the permission of adbd determines the permission of adb. You can view the source code in/system/core/adb and Android. mk. You will find that adb and adbd are

Then, let's talk about when adbd is started? The answer is the system service configured in init. RC, started by the INIT process. Check that init. RC contains the following content:

Android debug bridge (ADB) is a versatile debugging tool for Android Developers. It is indeed named the same. It builds a bridge between the developer and the target machine.
ADB usage is very simple, as long as you read the SDK documentation about ADB, (android-sdk-linux_86/docs/GUIDE/developing/tools/adb.html), and then a little exercise, basically, you can use
freedom. This freedom is called "root" permission.Visible, the freedom of root privilege is very large, if exploited maliciously, will put the whole system in danger (your text message, contact, your account password, your photo video, etc.). So neither the handset maker nor the Android system is actively open for root authorization. To get root permissions can only be done by non-normal means.So the existing approach to root access is only one way o

The "Ctrl. Start" and "Ctrl. End" attributes are used to enable or stop a service. Each service must be defined in/init. RC. When the system starts, the init daemon will parse init. RC to enable the property service. Once a request for "Ctrl. Start" is set, propertyservice uses the property value as the name to locate and start the service. The service startup result is placed in the property "init. SVC. Name>. The client program checks this value to obtain the re
