    And i have tried with some tools, UEFI Tool,HPUnlocker , etc. etc different tests,but the laptop doesn't even work with those so i am sure i am making some mistakes
    https://we.tl/t-YZiMabJVWz


    So can someone unlock the original dump (it has my win10 key inside and all the info as well) ? Because with the original it works fine.
    Try this unlock or not. Remove cmos or battery also.

          It automatically did something , first time i see something like that. In restore.

          But we keep missing , serials etc. and Windows key from the embedded chip.

          The good side,is the boot to windows, and that the options are not grey anymore.

                try the file @imranromi if it is Ok, you will not have to enter the DMI information, if it does not work, write again the bios sent by me and enter the DMI information ... here is the video ..

                  Re: HP Elitebook 850 G1 Bios Unlock

                  Hi

                  I bought hp 850 G1 in an unknown condition. I checked this model and the problem was a damaged bios, so I bought SOP8 programmer. In next step I desoldered two chips. One is 16 mb and second 2 mb. I cleaned both chips. My motherboard model number is 6050A2559101-MB-A03. I find in internet bios for my motherboard but the bios was to the HP 840 (this is the same motherboard model). So I flashed both chips and solder to the motherboard. Laptop turn on but I was glad too quickly.

                  In this moment i have two problems:

                  1. The following message was displayed: The Embedded Controler MUD data is not valid while MPM is locked. This in not a big problem

                  2. My second problem is more serious. My laptop has two graphic card (Intel and AMD). My operating system sees only Intel card.

                  So I have a question

                  Maby, someone has a bios (i mean 2mb file and 16 mb file) for hp 850 g1 without a password but with support for both graphics cards?

                  Please help.

                    Post your original bios backups, not the random ones you found on the internet .

                      This is imposible. The chip 2 mb and 16 mb bios was in half (i don't know) cleaned/broken. Looks like someone has damaged the bios or interrupted its update.

                      I need any bios with support both graphic card. In the future I will change the motherboard serial numbers if I have the appropriate bios

                            Hi.
                            After two weeks, I come back with the answer.
                            The Bios works great with my 850 G1 model. I enter serial number, sku, uuid etc with HP BIOSCONFIGUILITY. Everything works great. Thanks a lot!


                            ps
                            I can't edit my last post.

                              bios.bin required for hp elitebook 850 g1

                              hi everyone i have downloaded the correct bios update exe file from hp using the hp detect tool. the laptop has an administrator password on it which i don't have the password. i believe the bios has been attempted to be dumped and written using the hp unlock exe tool but the bios chip has been dumped with a bad dump and unfortunately has been erased and written with a bad unlocked.bin and now does not have a good backup of the original bios.bin

                              ch341a was used with a poor clip attached. I have now removed the bios chip. is it possible if I upload the manufacturer bios setup.exe file someone could make me bios.bin from it so I could erase the chip and then flash back the proper bios.bin that someone would be kind enough to make as I have no experience in creating or extracting a bin file from an exe file. if someone can help me out would be very much appreciated.

                                            I'm facing a problem with a locked bios with a password and i can't find how to remove it...

                                            The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).

                                            the Computer is a Unowhy small pc

                                            This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.

                                            The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know.

                                            Hi everyone, I have a HP EliteBook 755 G4 with a Biuos password.

                                            I've read the 16MB chip and patched using ​RCUnlocker_v_1_0 but seems it didnt worked, password is still there.
                                            Can you please help to remove the password?
                                            after first boot, there was an message thet firmware is restored, dont know if was suppose to happen.
