    Samsung Galaxy Book NP750XED

    Hi, need bios for Samsung Galaxy Book NP750XED-KC4ES.

    This board mounts a intel alder lake, and seems that the bios is corrupted.

    I tried two versions of flash image tool 16, and shows some errors and can't open it.

    This are the errors:

    Command Line: X:\MEA\FIT 16.0.15.1531\fit.exe

    INFO : Start decompose 'X:/MEA/samsung.bin' image.
    INFO : MFIT version used to build the image: 16.0.15.1554

    You have to use the same version of MFIT as bios was built, in your case 16.0.15.1554. You have attached bios cleaned and right version of MFIT.

        Bad news from this Samsung, same problem, it reacts to power button but there is no cpu vcore and no voltage for ram.

        Have no enable signal in pins 10/11 for dram pwm chip (TPS51486RJER)

        First time it recives power with the modified bios, (image.rar) could see some pulses at pin 1 of flash chip. (seems that kbc reads its firmware from bios at that moment)

        Could be that bios region is the one that is corrupted, but can't get a good bios from Samsung or internet.

        I will update when there is some news with it.

            There are some older bios updates that you can get from the microsoft update catalog. To do this,look for a string of hex in the bios above C.a.p.s.u.l.e.L.o.n.g.M.o.d.e.B.u.f.f.e.r (search for capsulelongmodebuffer in ASCII)

            Click image for larger version  Name:	Capture2.jpg Views:	0 Size:	76.5 KB ID:	3292498


            Select16 bytes after ÁþÄM 82 43 26 D6 7A 3B FB 51 B8 46 F2 48 46 CB 72 3B .Those bytes are a UEFI GUID,and they need converting to a standard GUID

            https://toolslick.com/conversion/data/guid

            convert 82 43 26 D6 7A 3B FB 51 B8 46 F2 48 46 CB 72 3B

            to a standard GUID D6264382-3B7A-51FB-B846-F24846CB723B .You can find this converted GUID in the bios using UEFITool.

            Now you have the GUID go to https://www.catalog.update.microsoft.com and enter the GUID in the search box

            https://www.catalog.update.microsoft...6-F24846CB723B

            Download the CAB file from any of the updates ,extract with 7-zip or winRAR.

            Check the GUID in the inf file to make sure it has the same hardware ID . https://www.badcaps.net/forum/troubl...ardware-id%60s

            Edit: Remove the AMI PFAT CAP header from P**CFG040.CAP using AMI_PFAT_Extract.exe then edit P**CFG040.CAP -- 1_00 -- AMI_PFAT_1_DATA_ALL.bin to the right size.

                it's quite easy, replace ABG with CFG from 1st links.txt of SMDFlea's guide, you'll get "ITEM_20240227_22345_WIN_P14CFG.exe" and in 2nd link paste this after "BIOSUpdateItem" and download bios file will start. Thou, i got an error trying to extract with "find_gz125.exe", bios.fd can't be extracted. Here's the bios update.

                  I`ve had errors before using drag n drop, since then i use Open instead.This one still had an error message but it did extract everything ok.

                    Hi volinakis, thanks for your help.

                    I have just downloaded the same file from Samsung just in case yours were corrupted, and have the same content and same problem when open it with find_gz.21.

                    Seems this file is corrupted or have some anti-unpacking technique.

                    Here is the error it shows:

                    Is it the same error it shows for you?

                    I hope somebody have a trick to overcome this.

                          It's not my case, I have open the file via open menu.

                          I'm using a win-pe system running in a Vmware virtual machine.

                          Tomorrow I will tray in a real windows 10 machine.

                            I`m using win 7. Try running find_gz in compatibility mode. If it doesn`t work you can get the updates from microsoft instead. Here`s your bios with the new bios region + DMI.The ME has not been cleaned

                            DMI 5A0094 - 5A203F (Length 1FAC)

                              Hi SMDFlea, I have tested in windows 7 but doen't work for mi, even in compatibility mode and 640&480.

                              I have got it running the ITEM_20240227_22345_WIN_P14CFG.exe as is, in win-pe and looking at temp dir. It's a bit tricky because the __Samsung_Update folder is erased in no time.
                              This is what I get:

                                I will test your bios and let you know.

                                Thanks.

                                  I've tested your bios without cleaning the me region, and nothing changes. I'm starting to think that bios is not the problem, but I will clean me region and test it.

                                  I've ordered a new ITE kbc just in case it were damaged.

                                  I hope next week the kbc will be replaced and the laptop working.

                                      Hi, yes it is a IT5571E 128.

                                      I 'm still waiting for the new chip.

                                      Is there any issue with this chip?

                                        Hi, a few days ago the IT5571E arrived, and after replaced nothing goes better.

                                        The client doesn't want to wait, so nothing more at this moment.

                                        Thanks to all that helps in this thread.
