    HPDMI unable to add SN after flashing BIOS

    Hi all

    I have an old HP Mini 1000 series netbook that I occasionally still use. I got a newer wifi card upgrade from an old junk laptop that was being tossed. I had to update the BIOS with a modded one to bypass a wifi whitelist check.

    Windows itself works ok, but when I try to add the model/SN/etc... with HPBQ193 (NbDmiFit_1.14B.zip USB boot with DOS) it does not save it to the EEPROM. The ESCD.dat file is created, says its saved, but as soon as you exit the app and start hpbq again all the info is gone.

    I dont know the policy of linking to other sites, but the bios-mod file I flashed is:
    361A0F15_NWL_ByCamiloml

    Any ideas?

    Thanks

          Here's backup of original.

          It's older 361A0 F12 version so missing some bug fixes compared to F15 and will not boot with 104 error due to new wifi card.

          model:HP Mini 1137NR
          SKU:NM119UA#ABA
          CTO:ABA
          serial:CNU.....FX

              Comparing the two BIOSes in hexplorer. In the original, the only place I see the serial number/SKU mentioned is in a little island of text starting at position ec000h in a huge sea of "FF". While ec000h in the NWL modded bios is all FF at the position. Would copying that block of text over to that position work?

                  So to answer my own question in case it helps someone else. Yes

                  Copied over block from ec000 and ec800 and flashing it restored back logo and hardware info.

                      HP Pro x360 Fortis 11 inch G9 Doesnt boot after flashing bios

                      This motherboard has 2 similar chips. One is on the front marked with BIOS SKT "Winbond 25Q256JVEN" and one on the back marked with U351 "Gigadevice 25B256EYIG". I ignored the one on the back and only desoldered front chip. Made a backup, made sure the reading was the same with another 3 backups.

                      I needed to remove bios password...

                      In search of advice for flashing bios via efi shell
                      by bql
                      Hi Badcaps,
                      I'm having the same Notebook and problem as in this topic:
                      HTML Code:
                      https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/3601016-need-bios-for-clevo-pd50pnp
                      I'm assuming that flashing the provided bios in this topic would solve my problem.
                      The only thing i can boot to is EFI shell
                      How do i flash the bios image in the EFI shell ? / Can i use any flash.nsh or is the executable interconnected to the bios image? ( i cannot find any bios related files in the internet...

                      Dear Forum Readers!

                      I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
                      I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
                      The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).

                      X270 - Bios flashing help
                      by Timeeez
                      Hello everyone,

                      I am still a beginner and want to learn more about flashing bios. First of all, thank you very much for the tutorials made on this forum it helps a lot.

                      Lets get straight to the point. When I try to flash the bios of my Lenovo X270 it restarts several times and always returns to the bios that was there at the beginning. When I get the bios from someone on the forum and write it to the bios chip, I always have the same serial numbers. I have the feeling that the pc is reflashing itself. Where could this come from? How to avoid this problem?
