We apologize for the inconvenience.

If you want to change back to Lenovo's official boot screen, you need to re-flash Lenovo's official firmware package.

If you have strong hands-on ability, have experience in flashing, want to flash the machine by yourself, and are willing to take possible risks. Personally, I suggest that you can go to Lenovo's official Lewen Firmware Zone**The official firmware operation of your device.

For your benefit, we recommend that you visit your local Lenovo authorized repair station and have an engineer assist with the upgrade. For specific tariffs, please consult the maintenance station staff.

Lenovo authorized repair site inquiry.

The business hours of the maintenance site are usually from 9:00 to 18:00 from Monday to Sunday, except for holidays, and the stations will be slightly adjusted according to their own operations.
