Download the bios update,Innoextract and HxD Hex editor
https://download.lenovo.com/pccbbs/m.../r01uj17ww.exe
https://constexpr.org/innoextract/
https://mh-nexus.de/en/hxd/
Drag and drop the bios update onto the Innoextract exe ,it will extract the updates into a folder called app .
Open $0AR0100.FL1 with HxD.
Select block 0 - 1E7 ( length 1E8) and click on the OK button.Delete the selected area with Edit -> Delete
or press the Del/Delete key on your keyboard.
Next, select block 0 - 7FFFFF (length 800000) 800000 is 8MB.
Right click or select Edit then Copy
Choose New File,then select Paste Insert
Choose Save, name it anything you want with a bin extension such as bios.bin
The update has an EC file as well,if you want it the start offset is 800000 and enter the length as 20000 . 128KB = 20000
Copy to a new file and save.
Your backup doesn`t have any DMI, its stored in the EC.It does however have a windows key.If you want to
copy that to the new bios select offsets 61D140 - 61D1DF in both,and copy/paste.

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,... -
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Hey!
I have a ThinkPad T480s, type 20L7-0026US, and it has the musical code for 0285: "TCG-compliant functionality-related error." After some research, it seems the BIOS could be corrupted and at fault. If my attached BIOS could be repaired, or someone could drop a good working BIOS, I'd appreciate it!... -
Hello everyone,
First, the data in brief:
Manufacturer: Lenovo
Model: ThinkPad L15 G3 21C3-0016GE
motherboard: LG4 LT5 ADL RT UMA MB 8L - 448.0PZ26.0011
IC Bios 1: MX77L25650F
IC Bios 2: MX25L25673G
EC Chip: NPCX997KAABX
So far I've been a silent reader, but now I need your help
I bought a laptop. The seller said the bios was locked. I was looking for a way to remove this ban.
I then got the CH341A and pulled the corresponding files from here https://www.badcaps.net/forum/troubl...evices-and-ele...
