But before you do the process of unlocking the bootloader, it’s worth noting that this process will DELETE all data in your internal memory, so you should backup all data first. After you have done the backup, then follow the steps below.
STEP #1 . First, download Minimal ADB and Fastboot and install it into your laptop or computer.
STEP #2 . Then open the folder where the application was installed at:
STEP #3 . Hold down the Shift key and right click on the blank area in that folder.
STEP #4 . Then there will be an option to open the command window or open the powershell window if you use Windows 10, just choose one.
STEP #5 . After that, on the Lenovo Z5s smartphone, go to Settings> About Phone> then press seven times the “Build Number” section so the developer option will be active.
STEP #6 . Back to Settings, this time open the “Developer Option” and select “Enable the OEM Unlocking” and “USB Debugging” then turn off Lenovo Z5s.
STEP #7 . After that, press the volume down button and power simultaneously for about 5 seconds to enter fastboot mode.
STEP #8 . If you have successfully entered fastboot mode, connect Lenovo Z5s using a data cable to your PC or laptop. To be more sure whether your Lenovo Z5s is connected to a laptop, try typing the command:
in the command prompt window or the powershell that you have opened earlier.
STEP #9 . When you finish typing the command above and pressing Enter, a random string will appear which indicates that your PC or laptop is connected to your Lenovo Z5s.
STEP #10 . Once connected, just type the following command to start the unlock bootloader process.
And press Enter, then at phone screen you will see a notification to press the volume button up, so press the volume up and wait for the process to finish.
STEP #11. Then back on the cmd screen when it’s finished, type the following command.
Wait until the process is complete. And if you have, then remove the USB cable from the computer. Then the system will erase all data as I said earlier.
When the process is complete and you turn on the smartphone, the boot process this time is rather long and will bring up a notification “your device software can not be checked for corruption, please lock the bootloader” which indicates that your Lenovo smartphone has successfully unlocked the bootloader.
