This is absolute BS.
Don't mislead people with such nonsense.

In each dump the area to be edited is located in different places, so specifying block addresses is pointless.
So at least you need to specify what you mean by pointing specific keyword or pattern to be searched for.

Re: hp elitebook 840 g4 need password unlock

i FOUND THE SOLUTION:
1- OPEN BIN FILE (16MB) using 'Hex Editor Neo'
2- Save as a copy (for example 'cleared file.bin')
(Dont modify backup, you can need it!!!)
3- Replace all caracters between 00b76064 and 0009c56b by 'ÿ' or 'ff' in hexadecimal.
4- Save again
5- Flash rom circuit using the new file 'cleared file.bin'... Enjoy
