I have got a Thinkpad L470 with locked BIOS. I havent done any BIOS unlock before. My question is, do I need a new pristine BIOS image and use it with the script, or is the script used with the dump of the exact same BIOS that you want to unlock?Leave a comment:

"Is there a way to use a single master BIOS dump to unlock the Lenovo E595 Type 20NF with an AMD processor? I have around 10 units and it would simplify my work. I saw such a solution for the E495 model. Thank You for any helpLeave a comment:

I had to try a few times, but I was able to get into the BIOS with this method, and now the P50 board is finally supervisor password free. Thank you for all of your help! I wanted to leave a comment about the success for future visitors.
which programmer and which software
Ch341 ??
if you can't, try EC bypass

I didn't know there were LPC lines here that I could use to get into the BIOS. I used that method several times in the past. I will give it a try here as well.Leave a comment:

It's actually quite simple: you have an AMD CPU laptop, and the auto-patcher was written for an Intel CPU.
A hash value in your patched file needs to be changed. I've already done that here, but you should follow the rules and post the serial number.
Then I can give you the new patch file.Leave a comment:

Guys, listen up, I have an issue. I'm trying to use patcher 0.2 on a Lenovo E959 20NF. I have 2 of them, and of course, they have a BIOS password. When I dump the BIOS and use the patcher, after flashing the patched BIOS, the laptop doesn't boot. I thought I was loading something incorrectly, but when I flash the original image back, the computer starts up fine. This model (E959 20NF) is listed as supported. Could someone shed some light on my problem? I would be eternally grateful.Leave a comment:

Hello 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

Hello 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... -

Hi, my laptop wont boot at all
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
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, 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,...
