Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Finally tried this on my T440p, and it worked like a charm. Used a SOIC8 clip w/ a Raspberry Pi. Only issue now is to remove the logo the previous owner put at the boot screen, I should be safe to update the BIOS as well right?Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Good day, I kindly ask for help from the Lenovo T495 type 20NK pc forum, I dumped the Bios and through your program I generated the PATCHED bin, mounted the W25Q128FW eprom, I turn it on but I only get a black screen and a series of beeps, reinstalling the original bios leaves quietly. Now reading here on the forum I noticed that many complain about this problem, but it seemed to me that two people talking about the T495 have succeeded. Before making other attempts, I would like to understand if anyone has managed to get the PATCHED BIOS to work. Attached I put my original BIOS and the version produced by Tools. Thanks for any help on this.Last edited by SMDFlea; 03-26-2023, 12:32 PM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I'm really sorry for my stupid questions but i spent like 1 or 2 hours looking for an answer:
I managed to get a dump of my T570 bios.
I used autopatcher to get a patched version of it.
How the f*ck do I get it flashed back to the notebook?
I used Universal BIOS Backup Toolkit 2.0 to get the backup.
Which software do you recommend to flash the patched BIOS back to the notebook?
Thanks for your time - I really appriciate your help!Comment

Don't waste any more time, there is no software methods for this job. You'll need a programmer to do it. No other options.I'm really sorry for my stupid questions but i spent like 1 or 2 hours looking for an answer:

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
thanks man. I thought if I can read it I could also just write it back.
Getting an TL866II and solder off the chip is not worth the amount of money/time/risk for my purpose but kind of interesting topic!

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
thanks, I've ordered it and will give it a try. As I've seen there is a kind of pliers I could connect to the chip without needing it to unsolder it. I'll let you know.
CheersComment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hey guys, I need some help, it seems I made a dump of my bios using a W25Q128BV in my CH341A Programmer and I only noticed now that my chip is a W25Q128JVSQ... now I'm stuck in the 2 beeps of death... Is there something that can be done do salvage this?
Can someone please help me to patch this?Last edited by SMDFlea; 03-26-2023, 12:32 PM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Got my ThinkPad X250 supervisor password cleaned, thanks for the app!
I thought my X250 was bricked when I heard 5 beeps at power up(motherboard failure) after flashing the patched BIOS. But it turned out the beep code was 5 short beep [pause] 5 short beep. Which indicates TPM is refusing to power up the laptop, probably due to tampered BIOS.
I redone the patch from Ubuntu and the checksum result is identical to the one generated from Windows so a falsely patched BIOS is ruled out. I almost lost hope as TPM("Security Chip") cannot be deactivated and it was the discrete TPM1.2 instead of PTT. I also tried ME cleaner(+patch) but to no avail, the laptop power button just flashed once then powered off.
Fortunately physical presence for clearing was enabled and Secure Boot was not enabled. I flashed the original locked BIOS and cleared TPM from powershell with clear-tpm -useppi, in hope that the TPM won't complain about the tampered BIOS again.
I flashed the patched BIOS again, then the laptop booted! I just followed the instructions and everything worked as it should. The program did say "TPM certificated changed." before "Turn it off." message. I used a CH341a with a worned out SOIC clip, I had to hold my fingers on the clip all the time when the programming is in progress. At first I used AsProgrammed but it was a hit or miss in my case, then I used Flashrom GUI and all is well.
Your mileage may vary but that's how it worked for me. Hard labor and time consuming but the result is great, saved me $50+ for BIOS unlock service.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I am in the same situation like you up to a point. With patched bios I get Lenovo screen, I press Enter at the ''interrupt start'' message. Then I press F1 to enter setup but I get black screen. I don't have any OS installed on my hard drive, do you have any suggestion?Got my ThinkPad X250 supervisor password cleaned, thanks for the app!

by macabookHello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

by piratiHello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder...-

With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried

by zeniusHello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...-
