What This Lenovo Tool Does

This online tool generates a small file called sn.img — which is required to unlock the bootloader on most modern Lenovo smartphones. Unlike older methods, you no longer need to request a code manually. Everything runs locally in your browser, keeping your data private and secure.

SoftwareCrushs Team tested this tool, and it worked flawlessly on multiple Lenovo devices.

Steps to Get Your Bootloader SN

Before generating the unlock file, you need your bootloader serial number (SN).

You can get it using one of these methods:

Method	Command
Using Fastboot	`fastboot getvar all`
Using ADB	`adb shell getprop ro.boot.bootload_sn`

Important: Your SN must be exactly 64 characters long.
If your phone shows the SN in two parts, just join them together into one line.

Unlocking Process

Once you have your SN and generated the sn.img file from the tool, follow these steps:

fastboot flash unlock sn.img
fastboot oem unlock

After running these commands, your Lenovo phone’s bootloader should be successfully unlocked.
