        It takes a very long time to sew two files, and I had little of it. Therefore, I tried the method from №281 (by filling in the FF block "NvramActiveRegn" in W25Q256JV_bottom) and the password was successfully reset.
        But still thank you for your help.
        Peace for everyone

                                      Look for AbtState using UEFITool, copy its hex code and paste it into the hex search of HxD and invalidate it by replacing AA 55 3F to AA 55 3C

                                        What type of program did you use for CH341A that can read the Winbond 25Q256JVEN chip? I installed several programs but doesn't seem to support the winbond 25Q256JVEN chip
