                  Hello. I need bios+ec for an 840 g8 computer. There is 5v and 3.3v, but the fan starts and stops once. The image does not appear. Can you help?​

                      Thank you. I already figured out the addresses in HEX and was able to remove the password from the EC bios file. Thank you for your fast reply
                      could you explain how to do this, please?

                        flash only this EC 2nd chip. it will promt endpoint security controller just ignore it enter. it will disappear in next boot.
                        next time use any hex editor fill with ff in this offset 00037000 to 000379df
                        i'm very grateful to you for sharing this knowledge with us. i managed it the first time, but in the case of my hex column, my offset wasn't like this: "00037000 to 000379DF", but I deduced it from the decoded characters and it was like this: "0003700B to 000379d7". I edited it by adding the "ff" although I already had it in some columns and it worked fine. THANK YOU VERY MUCH!!!

                        IF YOU HAVE MORE KNOWLEDGE ABOUT OTHER MODELS, I'M WILLING TO LEARN. 🤩🤩🤩🤩🤩🤩🤩🤩​

                                      Good morning Gentlemen of great wisdom. I need your valuable help in the following case: I have an EliteBook 840 G8 computer that arrived with a password in the bios. The first mistake I make is not taking the backup of the 3 chips before starting to modify. I tried to remove the password by unlocking the EC and the device turned on once but still had the password. The Second time I tried to unlock the password both Main Bios and EC. From that moment the equipment tries to start in a loop without providing video. I have tried the bios backups that are on the Internet and the same thing, I am sure that there is no missing resistance nor is there any altered nearby component, I must also say that everything has been perfectly welded. As additional information, I must say that with my bios backups the computer does not beep for a ram memory error, but with a backup found on the internet it does beep for a ram error but it still continues in a loop without video.
                                      HP EliteBook 840 G8, SN# 5CG1411K3R, Board CORVETTE-6050A3217501-MB-A01(A1) UMA HSN-I41C-4. The board is SRK1F (Core I7). I appreciate any help provided.

                                      Additional addendum: I suspect that the bios of Core 5 and Core 7 SRK1F are different if they are on the same board.​

As additional information, I must say that with my bios backups the computer does not beep for a ram memory error, but with a backup found on the internet it does beep for a ram error but it still continues in a loop without video.
                                      HP EliteBook 840 G8, SN# 5CG1411K3R, Board CORVETTE-6050A3217501-MB-A01(A1) UMA HSN-I41C-4. The board is SRK1F (Core I7). I appreciate any help provided.

                                      Additional addendum: I suspect that the bios of Core 5 and Core 7 SRK1F are different if they are on the same board.​
                                      here flash both.

                                        bios request/fixing dump HP elitebook 840 G6
                                        by wrinex
                                        Hi i received a HP elitebook G6 that had a The HP Endpoint Security Controller error when booted but 3 enters later you could use it in windows, i thought maybe a bios update helps...... i used the HP tool (it did not want to update from device manager,,, someting i did not even knew worked) after the update it bricked the laptop.

                                        i get 7 blinks on the capslock and thats it. i desoldered the chips front and back. and made a dump. i tried one bios posted here for the 16M and the 32Mb bios.. but it would not turn on or give an error code. so now i reflashed it back in its failed state...

                                        Bios password removal on a Unowhy dump

                                        Hi Everyone,

                                        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

                                        After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.

                                        My first attempt was to get the bios dump from windows...

                                        [REQUEST] BIOS Password Reset - HP EliteBook 830 G6 - Halt Code: qeh11u1kst
                                        by ShadeRunner
                                        Hi everyone,

                                        I’m a student currently locked out of the BIOS on my HP EliteBook 830 G6. I bought the laptop second-hand, and the previous owner didn't provide the password. I really need access to the BIOS to change storage settings and boot orders for my studies.

                                        System Details:
                                        • Model: HP EliteBook 830 G6
                                        • Processor: Intel Core i5 (8th Gen)
                                        • Serial Number: 5CG0080LKD
                                        • Halt Code (from 3rd fail): qeh11u1kst

                                        I'm hoping someone here can help me generate an SMC.bin file or provide a master password that works for this generation. Any guidance on how to get back...

                                        Dell OptiPlex 3090 Micro – Clean SPI BIOS dump needed (password locked)
                                        by Swatou
                                        Hi everyone,

                                        I bought a used Dell OptiPlex 3090 Micro with a BIOS administrator password that I cannot remove. Dell support refuses to help without the original proof of purchase, and the seller is unreachable.

                                        I would like to try flashing the BIOS chip with a CH341A programmer, but I need a clean SPI BIOS dump for this exact model.

                                        Here are my machine details:

                                        Service Tag: 50P1BB3

                                        Express Service Code: 10925963391

                                        Form factor: Micro

                                        I can share my current BIOS dump (read with CH341A) for comparison if needed....

                                        Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
                                        by Ahari
                                        Hi all,

                                        This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

                                        I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

                                        I...
