thanks for this,
but I already did it through hp part surfer and found that code, but when I enter it in the bios, it won't record it, it says that the code is not appropriate, I also tried via BCU but unsuccessfully, after restart there is still no feature byte in the bios.
so I just wanted someone to read it from the bios that I attached (both chips are read in the bios and EC and saved there in rar format) if this code that you, like me, found through the hp site and the one that is actually in the bios file are the same, then I don't know what else to do... but if it's a coincidence a code from the bios different from the one from the HP site would be great, because then there are high chances that the input will be successful and the "red counting" will be solved

Try this bios and see if it will let you enter the feature byte again

thanks
I'll try it and let you know

post S/N, full name and model, motherboard model, product number,etc.
Don't post pictures unless asked...write with the keyboard..
post the contents of the bios chip even if it is corrupted..
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Sorry peste for posting a picture.
I never realized that the chip has to be unsoldered and programmed outside of the motherboard.
Thats an impossible task for me, i don't have the skills and the tools, I just tought that it was possible to reset the bios password with some kind of software only.

TIA

You could use a clip .I think this model has a 16 pin chip, so you would need an SPI programmer, a CH341A would do, and a SOP16 clip. Using the clips is somewhat unreliable so you may need to make multiple backups until you get a good one.

I'm just letting you know what I've been doing, I removed the chip and entered your modified bios, after turning on the laptop, it did a security reset or something like that, the image passed quickly, so I didn't have time to read it. then I entered the bios (it didn't ask me for a code) but it asked for a feature byte entry, I entered it and it gave me the same INVALID FEATURE BYTE - CRC FAILED again. I tried again but without success. in the system I tried the same thing with BCU but nothing happened after restarting, then I repeated the process again via BCU and after restarting finally a screen appeared asking me if I want to record the changes where all the data is visible, including the feature byte. I don't know why he didn't want to accept the first time, I didn't type letter by letter, but copied directly from your post into the txt config file, and the second time he accepted....

thanks for your help,
it was solved successfully

Great, thanks for the follow up :-)
