          there are 2 versions of the bios U75 and U86.
          your bios is U86.
          my experience is that U86 gives problems with unlocking, maybe someone else has a solution

              Hello, instructions for resetting the BIOS password 1. Download the original dump. 2. Flash the unlocked file to spi. 3. When we turn it on, it will write an error that the checksums do not match. Writes a MANUFACRURE error. We enter the bios and reset all settings to factory settings. 4. Flash the native dump.
