LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Plenty of success with other models using this patcher but the Lenovo Yoga 12 has me scratching my head...

I successfully dumped and patched a Yoga 12 i5-4200 model, using the 4mb chip (furthest from CPU). However I'm not sure if I mixed up the boards and this one didn't actually have a password. Screen went black entering BIOS, I went through the keypresses anyway, when I flashed back to stock there was no password. Will check again tomorrow as I have one more passworded 4200 here.

The i5-5200 model won't work in autopatcher, file "is corrupted or does not contain a valid dump." Checked with UEFITool, it loads and looks ok.

I tried flashing the patched 4200 file onto the 5200 but it wouldn't boot. Reflashed the 5200 dump, laptop works fine (with password).

BIOS content also seems to change on every reboot, (dump has a different md5sum) but I can always get 2 matching dumps.

Tried again after updating to the latest BIOS (newdump.rar attached) - same issue.

File attached if anyone could take a look please.

Hi,
Successfully patched my T580.
It has a 28Q128JVSQ eeprom (16Mb)
I used a CH341A usb interface with colibri.
Here's my patched bios.
(It worked with hitting Enter key before the LENOVO LOGO)
Thanks a lot for all your work.

"T480original.bin is corrupted or does not contain a valid dump."

Try dumping the BIOS again. Make sure you have two matching files using md5sum.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Hello, i was trying to remove supervisor password from x240 and its looks like i break something.
I desoldered w25q128fv and created backup and patched image using ft2232h and flashrom.
When i flashed patched bios and soldered chip again motherboard is turning on but there is nothing on the screen fan is working for a while and its turning off. so i desoldered bios chip again and flashed backup and its still not working? Is it possible that something broke by running patch? or is it something with soldering?

No

or is it something with soldering?

More likely. Or (most probably) bad programming of the chip as usual.

Thanks for response, programming is good because I verified checksum after reading. What values should resistors near 25q128 have?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

@jku131
The resistors connected in series to chip DATA lines are 33 Ohms, PULL-UPS are 3.3k and the one for CS is 10k. Use picture as reference.

It looks like elements on motherboard are good. I flashed back bios backup and after running it in x240 I read it again and it changed. So its looks like motherboard is able to communicate with this, but i dont know why its not booting and modifying bios.
Diff: https://pastebin.com/0d4VxNDd in backup i have "ffff ffff ffff ffff ffff ffff ffff ffff" after running it its changed. What may be causing it not working?

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I have a T440p with a supervisor PW. I've never done any sort of BIOS modding before, I'm planning on getting one of these off Amazon. However unsure of what to do with it after, is there I thread I can read before proceeding with this tool?

Patch not work for yoga 12 5200.

not find solution for this, I think it's on SIO.
I have many mainboard of yoga 12 5200 with PW, not had time to test

you will especially have to train yourself to unsolder the bios,
Don't use the clip, you risk having a corrupted reading and know use the programmer
