    ACER VN7-793G - Neptune_KLS 16834-1M - BIOS.bin repair needed

    Good morning everyone,

    i have these two original BIOS dumps (original1.bin, original2.bin), but unfortunately i noticed after flashing another BIOS, that at least one of them or even both are corrupt...

    After a while of searching on google and youtube i tried to retrieve the DMI information from both with HxD, but i'm not really experienced with such cases and wasn't able to get the needed informations.

    i upload here a clear_mes.bin from another machine to compare and additionally the NPTKS111.bin, which i have extracted from official ACER download site and edited it to get the right size.

    I hope seomeone here can merge the missing DMI (to get the windows license too would be great!) into the NPTKS111.bin or knows a better way to restore the dump. i'd really appreciate it!

    The SPI is an MX25L6473F and the EC is an KB9028Q-C. It was really a mess to work with this SPI. Had constantly reading/writing issues also when soldered to the programmer, so maybe it's defective anyway. I tried all .bin above, but get no picture although all voltages are present and negative CapsLock test. So i still guess it's a BIOS issue here.

    Thank You in advance!

    EDIT: in case that you need the Serial, here they are. S/N: NHQ25EG0167420459A66000 SNID: 74201781866

    the posted bios are corrupt..the DMI and KEYWIN information cannot be extracted ... here is the bios extracted from the Acer site update ... try to read the bios from the bios chip and post, for DMI and KEYWIN..take the extracted bios as a model from the site..

      Unfortunately actually it didn't worked for my Case. This time I compared the written bios with the original one and everything seems fine. Got the Same issue like before, so i believe your BIOS is fine.

      Howewer, i suspect an issue with the EC. So i'll give it a try again after replacing it.

      Many thanks for your effort!

        Neptune_KLS 16384-1M - ECROM for ENE 9028Q C

        Good evening,

        Is it possible to get a working dump of the ECROM? Can't find anything at the known sources so far.

        Thanks!

            I didn't expect an fast answer, so thank you!

            But one additional Question, If it doesn't bother: isn't an replacement EC on this Board supposed to be auto-programmed after powering on?

            You can find the Schematics Here.

            Thanks again!

            PS: Sorry for starting a new Thread in this section. My apologies!
