Thanks very much for your help, I will give it a try when I take out the main board again....

SN#5CG1033RNM
CAMELLIA-6050A3136201-MB-A01(A1)
PRODUCT ID 113X7ET#ABU

I have tried running the script in tiny hexer to fix the endpoint error but it doesn't work. I get line 3, error 65: Cannot open file"C:\ENDPOINT\endpoint.bin"

file attached...

I have a Elitebook 830 G7 that has the bios locked, I removed the motherboard and the Bios chip (Winbond 25Q128JVPQ) I soldered the chip on my CH341A and read the data, I followed a youtube tutorial to remove the password by replacing lines of code with FF to remove the password etc, I then reinstalled the chip but now get HP Endpoint Security Controller Problem as well as the bios password is still there. I have obviously done some thing wrong.
I have now removed the chip again read the data and dropped it into RC Unlocker which has generated an unlocked Bin file. Could somebody please...
