    Re: HP Elitebook 820 G2 bios needed

    Still the same issue with 1.29, 25Q128 in correct position.

    I plug the CH341A, then the detect works fine, and then ... no erasing or programming works. If I unplug/replug it works x1 time ... then redetect do not work a second time ...

    Do you have a link to the 1.29 release + driver you used to successfully program the 25Q128 ?

    Thanks !

      Try it again, but this time:
      1.- Disable any antivirus (your app or the Windows defender)
      2.- Try to unzip again your Programmer app, on the first times I use it, one file is detected like virus, and my antivirus automatically disable it (without notification), so after antivirus and firewall disabled, the programmer run properly.

      I hop this works for you, otherwise, let me found how can I upload or find the source link where I download.

      Regards

        Hi,

        finally changing programer I was able to manage the Winbond chipset.

        I successfully flashed EC+BIOS.bin on a 840 G2 (somebody kindly proposed here the 2 fulldump files)

        But I've an issue as the Elitebook start in MPM mode (Ok), but then detect issue "not in commited state", reset the bios and restore a config ... and I lost the MPM mode not able to get it back and use wmdmifit tool to enter UUID, SKU etc.

        Does somebody successfully recover MPM mode to configure an Elitebook ?

        Thanks !

          Hello Satdream,

          I have a 840 G2 with bios password, and also have a ch341a programmer.
          I was wondering:

          you used a different hardware or software? And what hardware /software you used?

          Are those the files at post #4 of this topic?

          after this warning, you reset the laptop (10 times) before booting to windows so you could use winmifit to alter sku/ serial etc..?


          hope you can help me out,

          with regards,

            I finally ordered another SPI programmer (EZP2013) as with the CH341 I never successfully programmed the Windbond Q128.

            Yes

            No, after the warning, it was not possible to boot before the bios restored configuration (network etc.) and then the MPM mode was disabled before being able to boot WinME and run winmifit etc.

            Finally I got another Bios (here also) of 820 G2 (fully compatible with 840 G2), from somebody asked to clear password ... flashing with bios I got a fully workable laptop (no warning message etc.) BUT, I got also the SKU/Serial of the PC the Bios come from ... and not mine ...

            In any case for me the CH341 never worked for the main Bios chip, I tried several release of the software but once detected, then error to communicate ...)

            Hope this help

                    The bios provided by RIORENO Page 4 is working and allow to boot and work reuglarly with correct SN/SKU etc. BUT you'll not be able to change them ...

                                            Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).

                                            I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...

                                            I have this laptop that does boot but it's on an older BIOS that has issues with Secure Boot, and I cannot use the normal Razer BIOS updater because for some reason the serial number is missing / got deleted somehow (Common issue on this model, from what I've read). I got a dump of the BIOS chip (or at least what I think is the BIOS chip), and its 16MB in size - the files from the Razer BIOS update are 8MB. (There's two 8MB files, am I supposed to combine these somehow? Or combine with an Intel ME firmware? I have no idea).
                                            So, I'm looking for a BIOS dump for this machine - a 16MB one....

                                            Hello,

                                            I badly need bios dump for HP DM1-4000er,

                                            Model: HP DM1-4000er
                                            Motherboard: DA0NM9MB6D0 REV.D
                                            Product: QJ490EA#ACB

                                            Please help. My bios chip burned so I don't have the old bios anymore. I need bios dump before I can install the replacement.

                                            I need a BIOS dump for the Samsung S49CG934SU monitor
                                            by Habble7
                                            The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                            Suspected Cause:
                                            I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                            Troubleshooting Attempts:

                                            Nuc7i5BNH Bios Dump Needed
                                            by rednix01
                                            Hi everyone,

                                            I accidentally bricked my NUC7i5BNH after disabling the option to boot from USB, and now it's not showing any display at all. I tried the USB recovery method, but unfortunately, it didn't work.

                                            Local repair shops are quoting around $150 just to flash the EEPROM, but considering the unit is only worth about $75 these days, that’s not really an option. So I'm hoping to learn how to flash the chip myself. But to get started, I need a working BIOS dump for the NUC7i5BNH.

                                            I did come across a post with a dump for the NUC7i7BNH, but I wasn't sure...
