Are you kidding?

Your uploaded BIOS file is completely empty.

I would first try to create a reasonable backup of the notebook.

Ideally, create three backups.

And then read me how the auto-patcher works.

And the whole thing in English and not in Polish.

Good luck ...

Open the backup with a hex editor,it will be all FF`s . HxD hex editor -> https://mh-nexus.de/en/downloads.php?product=HxD20 .There is a polish version.
What model is your programmer, i`ll guess its a CH341A or EZP20** .Have you desoldered the bios chip or are you using a clip. Post a picture if you can of the bios chip on the board.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello,

After flashing the patched .bin on my T480s, my laptops screen stays dark and plays a short song.
Could anyone verify if the dump and the patch are actually ok?
And if not, could anyone try to correctly patch it?

Thanks!

You can check/verify this yourself by testing the laptop with the original dump, and regarding the patched file - yes, it is patched correctly.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Welp.. I put back the original dump and it's doing the same beeping sound. Sooo... I might have done something wrong.
I'll investigate more. Hope I'll be able to bring it back

Is it possible for the clip that came with the ch341a to damage the connection of the bios cheap to the motherboard?

LE: Someone in post #2190 suggested also removing the ram when flashing. I'll try that later and report back in case that fixes it.
What I did right now is:
- removed battery
- removed CMOS battery
- held the power button to drain any remaining energy
- connected the bios chip to my PC via the CH341A (with the 3.3v mod) and the included clip
- read the bios 3 times and verified that they are the same via SHA256
- auto patched the dump
- flashed it back
- reconnected the CMOS battery and then the regular battery

I also tried with the SSD disconnected and there was no difference.

Oh the Lenovo T480s model is tricky the resistors are placed way too close to

the EEPROM they can be damaged very quickly with the clip.

This interrupts the signal path so that the BIOS can no longer start.

Please be sure to look at the pictures, I've already had to repair it.

Good luck ...

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

So it seems like you know your way around a t480s
Can you also confirm which is the bios chip? There's two possible ones: one near the ram (which I supposed was the right one) and another near the wifi card.


Thanks a lot for the recommendation. I'll try to see if that's the problem and if I can fix it.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Update on my T480s that was making beeping sounds.

I managed to get it all working. What I did different was taking out the RAM (though I doubt that actually made any difference) and enabling all options in the "Write IC" drop down in neoprogrammer: Off-Protect, Erase, Blank Check, Write and Verify.
By default it was only Write and I didn't even notice the drop down menu there.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hi, I tried to unlock the bios of a Lenovo ThinkPad X380 Yoga via the Patcher.
For the backup of the Bios I used Asprogrammer V1.4.1, after which I patched the Bin generated with the Patcher and flash my bios. The problem, however, is that by turning on the PC the screen remains black, the fan runs for 1 second, the keyboard flashes and then everything remains off.
I tried to flash the backup but the problem persists. Can someone help me?
If it can be useful, I also made a backup with the "CH341A Programmer V1.3" program, which however gave me an error "Chip Main Memory with the content are in disagreement", and for this that I opted for As Programmer.
My fear is that the backup made is corrupt or has been done badly. In this case, is there a way to be able to flash a working version of the bios?
