Default Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

I have two Lenovo x250 that I am having trouble with, both with svp and at least one with computrace that showed up when I cleaned the ME region trying to get it to boot up. I have been successful with an X240 earlier, but no luck so far. I have included the generated patched files to both and yes, I did try the unlocked X250 patch files from Lenovo Unlock Dxe Driver Bios Collection. Same result, no beeps, black screen, mA consumption from 6 to 125 then back to 6, in a loop. Yes, I did find the security switch and another white switch, which corresponds to a hole in the backplate(cmos reset?)

Update: Nevermind, I got one done and working on the other one. Problem was that I was desoldering and soldering with hot air station and it wasn't soldering correctly, there is a lump of lead on the center of the BIOS chip pad, made it rise a bit, legs weren't reaching down I think. I cleaned all pads, tinned them again and laptop boots perfectly with the autopatch bin file. Let that be a teaching moment for me.

Hi! Does this work for a lenovo T560s? I have a supervisor password and computrace enabled & activated and I read several pages ago that removing the supervisor password using the auto-patcher could also disable the computrace? Thanks.

@s0ulf
The AllService solution that the Auto-patcher uses is a 2-in-1 solution, it will (1)reset the Supervisor Password and it will (2)deactivate CompuTrace (if enabled/active).

Hi,

Please can someone tell me what my SVR password is so I can go in and remove it?

Please see the attached 1.zip file. your help is greatly appreciated.

Default Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

Trying to do this on a t460s, i patched the file but after flashing it when I try to turn the laptop on the screen is black and the fans spins for 3-5s then it seems like it restarts. Any ideas what could cause this? Thanks.

EDIT: Reflashing with the original dump does the same thing
How fucked am I?

Glad to hear that it worked.
I think it is very important to have a good backup of the original BIOS file.
I always read it out three times myself.
Then I compare these three with MD5SUM to see if they are identical.
Only then can the whole thing continue successfully.
With best regards :

@s0ulf: That's what happened to me. Solder chip with soldering iron, check for legs fully joined to pads, no bridges. Is chip correctly positioned? Not upside down? Check with microscope if available, or invest on one, it will pay for itself.

I was trying by self, but patched file is identical to old. I used HxD redactor to compare them..
You can`t patch it because theres probably nothing to patch. The motherboard is NN-C771 ? ,what SIO does it have, i think its an ITE ,the password could be stored there, if it is you`ll need to find the pinout and flash it with a KBC/SIO programmer .
