[Admin]

1. Extract n1ctm04w.zip and run usbfmtpw.exe
2. Format the USB Drive
3. Disconnect the USB Drive
4. Extract u1u.zip (password for the zip is LenovoUone) and run u1.exe
5. Reconnect the USB drive and hit run.
6. Once the USB is created boot the USB Key and follow on screen instructions.

UPDATE (30/07/2021) [Try this if above method fails.]​

I have Included a ZIP file containing all the script that Lenovo Uone tool uses to make the process simpler.

1. Format the USB Drive with usbfmtpw.exe as usual.
2. Extract the contents of the LenovoUone.zip to Root of the USB drive.
3. Reboot and Choose your USB in UEFI Boot Options and follow on screen steps.
