      Hi

      Thanks i am surprised only 1 byte of change made difference, it did some changes in bios setup but one issue i cant change UEFI Passwors it states above "Some settings are managed by your organization" in security tab.

      you have any solution for this ?

                      Microsoft Surface Book 3 UEFI locked (AMITSESetup missing)

                      Hello.

                      I have completely locked 15" Microsoft Surface Book 3 (windows password, UEFI password + USB boot disabled). So I dissasembled it, desoldered Winbond W25R128JW NOR flash, read it with CH341 (with 1.8V converter) and now I am trying to find encrypted password (with UEFITool / HxD). But there is no patterns like this:

                      65 74 75 70 00 (AMITSESetup.)

                      01 4E 56 41 52 (.NVAR)

                      I am confused... Is there some kind of new protection mechanism?
                      Can you please give me some advice how to proceed?

                      Thanks!

                        probably the programmer read it with errors.. use these programs for CH341A...

                              Bios lock is gone, but there is also an "SEMM" lock. I asume that from this surface model reading(decrypting) bios password is impossible?

                                Hello guys! Need some help removing the bios password on this Surface Book 1 (1703). I have attached the old dump. By the way, did anyone have issues with sound and cameras not working due to a bios setting on this model? Thanks in advance!

                                      Hi.

                                      Yes, you are right. NV bios area is all FF. After some time I am pretty sure that it is because RPMC (Replay Protection Monotonic Counter). It is new NOR flash W25R128JW and if I understood it well, there is saved HMAC SHA-256 security key inside the NOR flash. Without knowing it, and without executing "Increment Monotonic Counter" instruction, the protected area cannot be accessed.

                                      How can I read this stupid chip please W25R128JW?
