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.

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).

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,...
