Flash all the original files of the device and take a screenshot to show me. I looked at your main bios file, it has no password.

I salute the tech giants in the house. Please i wish to find out, if i allow my programmer auto detect my BIOS chip and gives it a name that doesn't match what's written on the chip, could this affect the functionality of the chip when i reflash with the backed up bin file?

is the chip in the programmer's database??? choose the chip manually..if it is not in the database, you can choose a similar chip..nothing happens with the chip..

Could you help me please ?

Hi ! Peste

Actually I just have a password screen, when I miss the password 3 times it shows no code but just a message telling that I can shutdown or restart my computer.

I hope it's what you were asking, if it's not I'm sorry

Hello
I tried to unlock a locked HP ProBook 640 G1
It has a 25Q128 flash.
Unfortunately. the RC Unlocker generates an unlocked file, which is identical to the last bit to the original.
I attach the original dump.
Please help me if you can.

Serial is:
