Hello all. I have a lenovo T470s where bios is locked with supervisor password. I have ordered a tool which can read the W25Q128FVSQ (eeprom chip) and rewrite it. But I will need a patched bios dump for it. I have contacted certain service and they asked for my bios dump first and then they promised to send me the patched bios so that I can unlock my laptop. Unfortunately it did not go well so I am here for help.

Thanks in advance for any kind of help.

You should get support from the place you initially acquired the unlock service. Why complicate things?

I haven't received any unlock service from anywhere yet. I tried to contact one place but he didn't seem to be a friendly guy. So I haven't made any deals.

Hi , I am not looking for any free service and I remember contacting you regarding this. As I said to you , I will contact when my bios reqder chip is here and I have the dump. I was talking about the very first place where even after paying , I didn't get the service rather stupid comments.

a lenovo unlock costs 20, I am the cheapest provider, and do you know why it is not free? it took a lot of time and money to get this to work properly, the baker also earns on you and a painter asks for money too! succes with unlock

Seems like your bios dump is corrupt, that's probably why you haven't received a response yet. If corrupt, you can try to READ the chip again because you will be using this file once ThinkPad is unlocked.
Are you using CH341A programmer?

If you are using CH341A programmer with stock software, this may be the cause of dump being corrupt, usually does not matter what you do, original ch341a programmer software will always corrupt dump, usually near the end of the file.
For CH341A I suggest to use FlashROM software, only problem is it does not have a GUI, so you have to type the commands (read, write, verify, other).

Seems like it made a difference. I've just sent you a PM with patched file + instructions.

Post a picture and be more specific, as I understand that after programming the bios chip with patched file, during the Verification process it throws that error.
(Please also deactivate the CAPS-LOCK).
