If you own a Lenovo laptop or tablet and have stumbled across this utility, here is everything you need to know about what it does, how it works, and why it matters.
The tool can erase the locksettings.db and gatekeeper files directly from the userdata partition, effectively removing any screen lock without wiping the entire phone.
One of the most advanced features of the U1 Tool is the ability to repair lost IMEI numbers (common after flashing improper firmware) and back up/restore the NVRAM partition. This is critical for restoring cellular functionality.
