How to upgrade the kernel version of Android

The kernel of the mobile phone system is Linux, and the Linux kernel is upgraded by upgrading the system version. Upgrade Method:

1. Use the system update function of the mobile phone: In the settings of the Android phone - about the phone, you can see the system version of the current Android phone, and there is also an automatic detection and update system function. This is the system update function that comes with Android mobile phones, and its updates are mainly provided by mobile phone manufacturers, such as Xiaomi mobile phones, you can upgrade the mobile phone system version through this function.

However, using this function to upgrade the system requires a lot of upgrade files, so it is recommended that you do it in a WiFi environment; [The use of the mobile phone's built-in system update function is only more practical for some brand mobile phones, usually many brands of mobile phones come with the upgrade function, which can be upgraded very slowly, and cannot be updated to the latest Android system version, so it is generally not recommended to use this method to upgrade];

2. Mobile phone system upgrade package: Generally, the official website of mobile phone manufacturers will update some system file packages for users to upgrade, we can enter the official website of our own mobile phone brand**center, and then according to our own mobile phone brand model, **the latest system update upgrade package,**stored in the mobile phone SD card. Then we go to the phone settings again, then select "About phone" and finally find the "System update" option, after which we are in the option "Memory card upgrade".

If there is an upgrade package available in the SD, the upgrade will be started automatically;

3. Upgrade the Android system by flashing: For Android phone users, the enthusiasm is to brush the machine, flashing is a very effective way to upgrade the Android system, there are also many Android mobile phone ROM systems on the Internet, and the update is very fast, you can choose to use the latest Android system kernel to flash, so as to achieve the upgrade of the Android system.

It's not the same thing.

The version of the Android kernel refers to the version of Linux used at the bottom layer, and the Android version refers to the version of the SDK provided by Google. In general, there is a correspondence, but in practice there may be deviations.

Since May 2009, the Android operating system has switched to desserts as the version codename, and these versions are named in uppercase order: Cupcake, Donut, Éclair, Froyo, Gingerbread, Honeycomb Ice Cream Sandwich, Jelly Bean, Kitkat, Lollipop.

It's the kernel version number. Learn about the kernel and version number! Android, Google, Version, Derivatives, Linux The Android operating system is a mobile operating system developed based on Linux, and the underlying Linux kernel only provides basic functions.

Android's kernel is equivalent to a derivative of the Linux kernel, and Google has added something of its own to it. Take out your mobile phone and open the kernel version of Settings > About Phone to view the kernel version number. The official kernel version number is the current and current kernel version numbers.

1. Kernel: An operating system is a low-level support software that deals with hardware and provides a limited set of services for user programs. A computer system is a symbiosis of hardware and software, which are interdependent and inseparable.

The hardware of a computer, including peripherals, processors, memory, hard disks, and other electronic devices, make up the engine of a computer. But without software to operate and control it, it can't work on its own. The software that does this control is called the operating system, which is called the "kernel" in Linux terminology, and can also be called the "core".

The main modules (or components) of the Linux kernel are divided into the following parts: storage management, CPU and process management, file system, device management and drivers, network communication, and system initialization (booting) and system calling.

2. Kernel version number: Generally, you can distinguish whether the system is a Linux stable version or a beta version from the Linux kernel version number. For example, 2 represents the major version number, 4 represents the minor version number, and 0 represents the last version number with minor changes.

In the version number, the second digit of the ordinal number is an even number of versions, indicating that this is a stable version that can be used, such as, while the second digit of the ordinal number is an odd number of versions, which usually has some new things added and is not necessarily a very stable test version, such as. This way, the stable version** is upgraded to the previous beta version, and a stable version is not developed once it has reached full maturity. Take the official version number of ME600 as an example:

The main version number, 6 is the minor version number, and 27 is the last version number. Judging from the parity of the minor version number, 6 is an even number, which shows that this kernel version is a stable version that can be used. The last version number of 27 is the number of bug fixes.

Of course, the kernel version that can be used as a phone must be a stable version.

3. The latest version of the kernel: The latest version of the current Linux kernel is, for details: For mobile phones, the kernel versions in the generally officially released ROM are: for.

The Linux kernel is upgraded by upgrading the system version, but before you upgrade the system, you have to make sure that your phone has a new system!

First of all, why are you upgrading?

Replacing the kernel is a system-level adjustment, which can be solved by a general upgrade:

Implement patches for large available memory. Modify core parameters at the expense of hardware performance in exchange for larger memory, such as overclocking cores.

The way to replace is to upgrade the kernel file of the system, the common kernel upgrade patch is released in zip format, use cmw to flash your kernel file and restart, that is, complete the kernel replacement. It's no different from brushing ROMs.

Some kernel patches are released with the firmware ROM, and the kernel can be replaced by flashing the ROM directly.

Since replacing the kernel is a system-level operation, be sure to confirm that the kernel matches your model system, otherwise the system may not boot.
