How to upgrade Sony Ericsson MT15i to Android 4 0?

Just upgrade directly on the official website, in the official website of Sony Ericsson**"Update service" first select your phone model, then connect the phone with a data cable, and then follow the steps step by step Just follow the steps and it's no problem!

Direct update service to the official website to upgrade. If it doesn't work, then just use software to flash the system.

Just these two methods.

We don't know if that brother is here to ask the problem or to advertise. The number of words in the ad is more than the word count of the TM question.

Let me tell you more about it.

1. The boot speed is accelerated. It's basically about 30 seconds. And the power consumption is significantly increased, and under the same setting, it is faster than the power consumption.

2. The lock screen animation has been changed.

3. Strengthen the fluency of operation and improve the running score. Except for the controversial iO, the other items are very close to the dual-core sensation score.

4. Camera function enhancement. For example, digital zoom. Only 2m (i.e., at 200W) can zoom, and it is possible to zoom up to 2m or more.

However, after opening the camera, the selected photos cannot be viewed in landscape orientation. The photo interface will change according to the horizontal and vertical screens. The **browser that comes with the camera is gone.,Can only be replaced by other**browsers.。

There is no option to click at the bottom of the screen to view photos, and you must press the function key to appear. Switching between night mode and day mode is more user-friendly, for example, when you set a daytime camera value and then switch to night mode, the previously set parameters will be saved. However, after switching back and forth, the previously set value will be replaced by the default value of the system and will not be retained.

6. There is a space for sending a text message, and the color of the SMS dialog box changes to blue.

7. Add themes and other software. There is more theme option and comes with 7 themes to choose from. The software also adds several more system software and chicken rib software.

8. Some software that previously required permission to delete can be deleted. For example, Kaixin.com. But it doesn't seem to be the whole story.

9. Increase the volume of XLOUD by nearly 30%, and the external sound will be significantly enhanced.

10. The call interface changes, the UI changes greatly, the sensor becomes more sensitive and the commonly used contact parts appear.

11. The appearance of the Timescape widget has been changed. The settings inside have also changed slightly.

12. When some programs press the home button to the main page, a light blue circle will appear around the screen, and there will be no screen when you move itFor example, when coming out of UC. I don't know why.

13. The brightness of the screen has increased significantly. Turn on the highest brightness in the sun, read the text of the web page**No pressure, there is pressure. If the brightness is represented by 100, there is at least 140! However, the increase in brightness also increases the power consumption.

14. Some programs can rotate the screen without turning on the automatic rotation, such as the user guide, which seems to be absent.

15. The sensitivity of the light sensor is reduced, and the screen is no longer flashing like that, and the transition is smoother, although it will still flash, but the amplitude is not so large. This is what someone else said after testing, and mine didn't find it.

16. The operation when connecting to the computer has become simplified. Don't go through the hassle like you used to.

17. More traffic. Someone has done such a test. The firmware does not turn off the background data at night, and the 360 monitoring traffic only runs about 4k overnight. After the upgrade, more than 100k traffic was run on the second night.

There are a few other minor changes that I won't describe here.

Three methods: 1. Use official tools such as PCC and Sony US to connect to the computer and upgrade.

2. Flashtool flashes the official firmware. It is a kind of brush machine, which is simple and convenient to operate, and is commonly used to save bricks.

3. Recovery card swipes third-party ROM. It's harder for newbies.

Switch to PCC or US, and then follow the prompts to do it.

I'm also 15.,Suo Ai's machine is more troublesome.,If it's the 62 version, you can only use flashtool to brush the root after downgrading, if not, you can use the ordinary method ** Master Zhuo to complete。
