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. 🤩🤩🤩🤩🤩🤩🤩🤩

Read the updated rules, the laptop serial number, SNID or service tag must be posted with all bios requests https://www.badcaps.net/forum/troubl...before-posting

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.
