Look for a directory containing files named LOGO.BMP , LOGO1.BMP , or a utility named WINUPTP.EXE .
Your preferred installation method ( or UEFI firmware editors )
The real villain is and BIOS digital signing . Lenovo’s BIOS updaters ( WinFlash64.exe or the $0A82000.fl1 files) contain cryptographic signatures. If you attempt to swap the OEM logo using a hex editor without resigning the file, the BIOS flasher will reject the update with an error like:
For a safer approach without manual registry or BIOS editing, the Lenovo UEFI Boot Logo Changer on GitHub allows users to swap images by leveraging the EFI System Partition. lenovo oem logo bmp 120x120 patched
Lenovo officially supports custom startup logos through their WinFlash or System Update packages. Step 1: Prepare the Image
BIOS splash screens generally cannot decompress files; the BMP must be raw.
If you are searching for the "patched" experience, you are likely looking for software solutions that automate this process or enable it on unsupported hardware. Here are the top three tools used by the Lenovo modding community: Look for a directory containing files named LOGO
: Many older Lenovo BIOS frameworks hardcode the OEM display box to exactly 120x120 pixels. Images exceeding this size will either fail to flash or cause screen distortion.
Modifying BIOS assets carries risk. Flashing a corrupted or incompatible "patched" BMP can result in a bricked laptop that fails to POST (Power On Self Test). It is crucial to ensure the image format matches the specific model's requirements exactly.
: 24-bit RGB (8 bits per channel) or 8-bit indexed (256 colors). Compression : None (Uncompressed). If you attempt to swap the OEM logo
When you boot up a Lenovo computer, the initial screen displaying the Lenovo logo is stored within the BIOS/UEFI firmware. This image is not just a standard image file; it must meet specific criteria to be recognized by the system's firmware update utility. The logo must be in BMP (Bitmap) format. Dimensions: It must be exactly pixels .
