Apply update from adb什麼意思

"Apply update from ADB" is a command or option in Android Debug Bridge (ADB) that allows you to apply an update to an Android device from your computer. ADB is a versatile tool that enables you to communicate with and control Android devices from the command line.

When you issue the "apply update from ADB" command, you're telling ADB to install a system image or update package on the connected Android device. This command is often used by developers, system administrators, or advanced users to update their devices manually, especially when they are working with custom ROMs, kernels, or when they want to flash updates that are not available through the traditional OTA (over-the-air) update mechanism.

To use this command, you typically need to have the update package (often in the form of a ZIP file) on your computer and then use ADB to push it to the device and install it. The exact command and its parameters can vary depending on the specific update package and the version of ADB you are using.

For example, if you have an update package named "update.zip" in the same directory as your ADB tools, you might use the following command to apply the update:

adb reboot bootloader
adb sideload update.zip

The first command (adb reboot bootloader) reboots the device into bootloader mode, and the second command (adb sideload update.zip) actually applies the update.

Please note that using ADB to apply updates requires a certain level of technical expertise and should be done with caution, as it can potentially brick your device if not done properly. Always make sure to follow the instructions provided with the update package and to back up your data before proceeding with any system updates.
