Why can t I get root access to my Sony Ericsson LT15i 4 0 4 system

I'm using MT27i, and I hope my root method can give you some help.

The MT27i was upgraded to a version around November last year, and Sony's customized UI version was.

Abbreviated as version 154, the new version comes out, and the old version of the root tool becomes invalid, so how can the new version also get root permissions?

That's where the Xperia comes in handy.

Those who have used Sony's third-party flashing tool, all know that there is a software called flashtool, which can flash the Sony TFT flashing package, and can also be flashed into the kernel in the flashing package or Sony's own APP

Then you need to use the method of replacing the kernel to obtain root permissions, replace the existing kernel of the higher version with the kernel of the lower version (as long as it is the kernel of the same mobile phone model, there will be no problem with flashing in), and then use the root tool of the lower version of the root, and then flash back the kernel of the version you are using now (to prevent the stability of the system part), and the root is successful.

The LT15i factory version should be or no, the next flash pack, then the next flash pack, let's go.

One-click root method Root is not as difficult as imagined, and there are many software that can do it. Root software like z4root, universalandroot, gingerbreak, and others are more convenient.

Z4Root believes that many Android pepper friends have heard of it, and it is indeed a very awesome Android phone root access access acquisition tool. As long as the user installs and clicks the root button, the software will automatically root with one click, and no other operations are required. In fact, it is not as difficult to obtain root access to Android phones as imagined, and you can practice it yourself.

4.Click Start Root, the whole process will restart the phone 2 times, it takes about 2 minutes.

Yes, each mobile phone has a different way to get it, check it.

There are detailed explanations in forums, such as the Blade forum.

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。
