Hey guys
i have a Surface Pro 4 with corrupted UEFI
i have found an working image
but there are other DMI infos
Dump:
can someone help me to combine my original dump with the working image
or tell me how i can do that
thank a lot
DMI information is in NVRAM which is destroyed in your original bios.
is there no way to add original serial number to original image?
i have the touch firmware in es UEFI Screen but Touch is no working
i need the DMI beacause machine is locked with bitlocker and i think it needs ther original information to boot up without problems
when at first touch was working its okay than i can recreate bitlocker code
Bitlocker can use different ways to unlock an OS drive- a user password, information in TPM, secure boot, ad for domain computers- all options alone or in combination… The DMI information in NVRAM isn’t one of these options.
okay thank you for your help
is their a way get touch working
and do you can add my serial nr in the working image ?
That’s the only solution regarding loosing touch when updating firmware / ME I know of:
For the NVRAM: Use UEFIToolNE, you might copy the relevant entries from a firmware with uncorrupted NVRAM to your own firmware and edit them with the correct values.
do you can change the nvram of the original bios with the working one ?
thanks you alot man
with your advice the maschine is now running again
i have copied the NVRAM from working dump and touch is also working now
