T470s failed dump options

[disgruntled]

Hi everyone,

I wanted to flash and patch a BIOS file from a Lenovo T470s (to reset the BIOs password), but I had incorrectly dumped/saved the original BIOS file incorrectly. I selected the wrong chip and it only a fraction of the data saved. Big mistake, but learning a lot.

I do have another computer of the same model, but I realize flashing a copy to the other would not work due to the ME region details.

What are my options for unbricking or salvaging? Don't really think it's worth purchasing another motherboard.

Thanks!

Upload your reading. It can be rebuild so Ethernet MAC stays the same, if GBe region is part of your readout.
ME region can be a cleaned one and also BIOS region can be extracted from Lenovo Updates

Like the partial data that I was able to save? You'll see that only 1 MB of the 16MB I was able to save

Thanks for the attempt, but didn't work. What I notice is strange is after I flash and read the file. The analysis shows that it is not identical to what I've flash. I've attached the read file.

Take bios from that laptop, clear ME to use. Or change with new bios chip.

What if the GBe region is different? Would that not work?

You must try to know.

Understood thanks. The CSE ME file should match the working BIOs correct?

If the BIOs I'm trying to flash had a password previously before I bricked it, are there things I need to consider when cleaning the ME region.

Re: T470s failed dump options

I think, cleaning ME region can't not delete the password.

I figured. Are you aware of anyone patching not the original BIOS and getting it to work? From what I understand, replacing the BIOs chip wouldnt work either if it had a BIOS password.

Sounds like I should probably just dispose of this

Have you tried unlocking with AUTO-PATCHER ? Back up the original bios carefully before you do that because you'll be near to re-flashing it.

One of them I'm not trying to unlock. The one that I bricked I was trying to unlock but improperly backed up bc I selected the incorrect chip. Now I'm autopatching a BIOS from another same model computer and flashing on another computer. Am I wasting my time?
