      Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

      Hello! Please help with reading bios. Tested few dumps from few T450 and 13 - always issue "dump corrupted or does not contain a valid dump".

      here some axamples:

      Cheched on another clean W10 pro...same issue. I cant understand problem in dump or in pyton...

      Created dump in Colibry and dump has been patched. New issue - after replacing patched dump with original laptop stuck on a black screen. Original dump not solvind an issue...

                        Re: BIOS Programming - Which programmer to use??

                        Hello,
                        A bit off, but I don't want to start a new one for one question.

                        I would like to read my bios chip.
                        I try and try and try, but cannot.

                        With chinese app it read, but verify wrong at 50%. All the time at 50% .
                        The russian app detect my chip wrong.
                        Image attached.

                        My laptop is Lenovo T450.
                        Chip is : W25Q128FVSQ

                        I tried a T460 with similarly chip, and there was no problem.
                        It read it both chinese app and russian app too.

                        My laptop working. Running Windows 10 on it.
                        Only the bios have password.

                        Why I cannot read my laptop chip?
                        My chip image attached.

                            First of all thank you so much for helping.

                            I have a question:
                            I am following this guide:
                            https://winraid.level1techs.com/t/gu...rammer/32948/2

                            But this Neo Programmer app is different.
                            Example I cannot found:
                            "Go to "Auto" and uncheck "Erase" and "Blank check" options:"

                            I am not sure how to do with this app what is in that guide.

                                Thank you so much.

                                Could I ask, how I know the bios file what I read and save it, that is correct? I have to compare with the one which downloaded from the manufacturer site.
                                But there is only exe and iso.
                                I unpacked the exe, but the rom file not include the bin file.
                                The iso not include too.
                                So I have no bin to compare with.
