Sony mobile unlock tool

Fastboot driver

Fastboot Tool

IMEI number of the mobile phone (used for unlocking)

Connect to the Internet (used to unlock)

3. Procedure

Extract the tool to one place. For example, drive C.

3.1 install driver

Whether unlocking or obtaining root permissions, the mobile phone must be in the fastboot status. The driver must be installed when the mobile phone enters the fastboot status. I did not carefully differentiate which features were used, so when installing the driver, I checked all the check boxes, that is, complete installation.

After the installation is complete, restart the computer. I use 32-bit xp. If you use win7 or 64-bit OS, you cannot ensure that the driver can be correctly installed. If the driver fails to be installed, it may be stuck in:

C: \ fastboot tool> fastboot FLASH Boot rooted_kernel_st27i.elf

<Waiting for device>

 

After the driver is installed, the mobile phone can enter the fastboot status:

The mobile phone is shut down. Connect the power cord of the mobile phone, and press and hold the phone's upward volume key to Connect the other end of the power cord to the USB port of the computer. At this time, the lights on the mobile phone will change to blue and continue for a period of time.

In this case, you can see an Android phone device in the Device Manager, which marks the successful installation of the driver.

 

3.2 unlock.

Install and execute the unlock tool.

Here, you must unlock it, no matter whether it has been unlocked. Unlocking will clear application data on the mobile phone, so back up the data in advance. The IMEI number and network connection are required during the unlock process.

When the mobile phone enters the fastboot status, open the unlock tool, click one-click unlock, and enter the IMEI number. OK. After the unlock is successful, the mobile device starts automatically.

If it is not unlocked, an error occurs:

C: \ fastboot tool> fastbootflash boot rooted_kernel_st27i.elf

Sending 'boot' (7462 KB )...

Failed (Remote: The device must be rooted first)

Finished. Total time: 0.031 s

3.3 run the command

After the unlock is successful, shut down the device again and enable the mobile phone to enter fastboot mode again.

Go to the directory of the fastboot tool,

Then execute the following two sentences:

Fastboot FLASH Boot rooted_kernel_st27i.elf

Fastboot reboot

The execution is successful and the mobile phone starts automatically.

OK. The root permission is obtained!
