Some system apps can be disabled using ADB commands (without root).
Generally uninstall system software Take system update as an example, there are two ways:
1) Disable ADB tool uninstallation.
2) Obtain root privileges, flash modules to disable upgrades.
This article describes the first method. This method is more secure and reliable than rooting.
However, it also needs to be used with caution, and it cannot be deleted randomly to cause bricking.
1. What is ADB and fastboot?
The full name of ADB is Android Debug Bridge. The role of the debug bridge is the debugging interface. It is a client-server (Android) program. ADB is a tool of Android SDK, which directly operates and manages Android devices.
ADB connection physical method:
adb supports two ways to connect to the Android system, USB and network. Generally, the android device will be set to the USB method by default (directly plugging in the data cable). A service (adbd) is running at the bottom of the android system. Inside the mobile phone system, manage the adb command connection on the computer side. This service will monitor the USB connection or network according to the configuration of the mobile phone when it starts.
How to connect the mobile phone with ADB command The mobile
phone is connected to the computer via USB (install the driver first) or WiFi. The
mobile phone turns on the debugging mode: Options-click the version number 8 times until the developer mode prompt pops up-developer options-debug mode
task manager close the mobile assistant software , to avoid port conflicts
adb devices 则默认连接到手机,默认端口为5037(USB)
adb connect/disconnect 手机IP地址(WiFi)
Some commands and folder execution require ROOT permission.
The adb version must match the mobile phone system.
Two, ADB installation
1. ADB download
ADB download address 1: https://adbshell.com/downloads
ADB download address 2: https://developer.android.com/studio/releases/platform-tools.html
Go to https://adbshell.com/downloads and select ADB Download the Kit toolkit. After the download is complete and decompressed, you can get the following three core files:
2.ADB driver installation
Generally, the data cable is directly inserted and installed automatically.
3.ADB installation
Method 1:
My Computer-"Right-click Properties-"Advanced System Settings-"Environment Variable Path-"Add adb tool path.
Method 2:
Cut the three files into the following two directories
C:\Windows\System32
C:\Windows\SysWOW64
4. fastboot installation
Fastboot, means quick start. Fastboot is a firmware communication protocol for a computer to flash, erase/format, debug, and transmit various instructions to a mobile phone's firmware through a USB data cable. It is also a command-line tool in Google's Android SDK Platform Tools. The USB driver for the phone needs to be installed on the computer.
In Android phones, Fastboot is a lower-level flashing mode than recovery (commonly known as fast boot mode).
Compared with some system card brushes, wire brushes are more reliable and safe. Fastboot literally means quick start, and it can also be regarded as a flashing interface, but it is lower than recovery, and this bottom layer is closer to the hardware layer.
When the phone cannot enter recovery, it can also enter Fastboot to save. When you cannot enter Fastboot, there are also Qualcomm 9006/9008 ports, MTK ports, and QCN ports that can be saved. But when the computer can't even connect to these phone flashing ports, it's a brick.
Three, ADB use
Step
1) Mobile phone - "Enter developer options -" Turn on USB debugging
2) Connect the mobile phone data cable to the computer - "Computer cmd enters the small black box
3) Use the adb command, see Chapter 4 for details.
For example, check all the packages in the system
to uninstall the system
You can unplug the data cable after uninstalling the apps in
Four, ADB common commands
adb devices //查看adb已连接的设备信息，出现序列号和device表示已正常连接设备
adb shell pm list packages //查看所有已安装应用的包名
adb shell pm uninstall -k --user 0 包名 //卸载包名所对应的软件（卸载命令1）
adb uninstall 包名 //卸载包名所对应的软件（卸载命令2，与卸载命令1功能相同，2选1即可）
1. Check the adb version
C:\Users\30608>adb version
Android Debug Bridge version 1.0.29
There are also other effects, it should be that there is a problem with the installation path
E:\other>adb version
Android Debug Bridge version 1.0.41
Version 29.0.1-5644136
Installed as C:\Windows\system32\adb.exe
2. View all packages in the system
adb shell pm list packages
3. Uninstall the software corresponding to the specified package name
adb shell pm uninstall -k --user 0 package name
How to choose the corresponding software package
Method 1) View the uninstalled software package name on the mobile phone through third-party software (such as APK viewer, etc.), for example, the package name of the system update here is com.android.updater
Method 2) Open the system settings— —Application Management, select "Show System Services" in the upper right corner. Click the application below, and then click the ⓘ icon in the upper right corner to view the application package name.
Prompt Success means uninstallation is successful. Take uninstalling system updates as an example
