Android 2 2 to 2 3 and Android 2 2 to 2

It's not theoretical, it's absolute!!

However, after flashing, the system may not be as stable as it used to be...

It's just a little more than a little more function.,Just a little bit.,So if the original system is not a big problem.,It's recommended not to flash the machine casually.。

After all, the damage to the hardware of all parts of the mobile phone is still quite large...

Hope...

It mainly depends on whether the phone model and hardware support Secondly, liters are completed by flashing, not upgraded CPU600 or more, rom512 or more, RAM256 or more, basically can be flashed, mainly to see if your model has an official upgrade package, a personally-made upgrade package, and it is best to use it after testing.

Theoretically, as long as the hardware can be installed, the hardware specifications can also be installed, but whether it can be upgraded depends on whether your machine has an official website ROM or a private ROM. If you have it, you can install it.,Just like my V880,I bought the orange telecom version.,The system that came with the machine at the beginning.,Later, it went down to the civil.,Now it's changed to the ROM.,It's all running normally.,And it seems to run more efficiently.。

It's a question of what version to choose for flashing.,But the configuration requirements are higher.,It's up to your phone.。

You can go to that kind of mobile phone store, an ordinary mobile phone store, and ask someone to help you upgrade.

At present, Android mobile phones are mainly upgraded in the following ways:

1. Use the system update function that comes with the phone.

In the Android phone's settings - about the phone, you can see the current Android phone's system version, and there is also an automatic detection and update system function.

PS: The system update function that comes with the mobile phone is only more practical for some brand mobile phones, usually the upgrade function that comes with many brand mobile phones can be upgraded very slowly, and it is impossible to update to the latest Android system version, so it is generally not recommended to upgrade in this way.

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".

3. Upgrade the Android system by flashing.

For Android phone users, the enthusiasm is still flashing, flashing is a very effective way to upgrade the Android system, there are also a lot of 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 is recommended to use it, and there are requirements for the configuration of the mobile phone.
