I am now trying to replace the BIOS Region in my Dump by the BIOS downloaded from Lenovo.
I have identified the correct files for my machine (N2HETxxW) and found 2 files, FL1 and FL2.
As I assume, FL2 is for the EC and FL1 contains the main BIOS.
I just cannot figure out, what to do with the FL1 file. There are many guides out there, that start with removed a small section in the beginning and then ending up with the BIOS file. That does not work for me, since the FL1 is a lot smaller than the dump.
Could someone please provide a guide as to how to proceed with these files?
Thanks in advance!
Attached is the Dump as well as the FL1 and FL2 files from the Lenovo Update Package.

Hi everyone, hope everyone's having a great day.
I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.
So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
Does this mean the BIOS is fine? making it a hardware issue?

I've currently got a Lenovo Yoga Slim 7 14APU8 that is not posting. Its fan spins, the keyboard lights up, and the caps lock doesn't work. It was taken to some shop for cleaning, and then they updated or tried to update the bios. After that, there was no display and no post. I've removed the bios ic from the board and made a bios dump. I need some assistance going forward, as I suspect this is probably just a bad bios issue. I've tried searching for a dump, but no luck; if anyone can throw me a bone, it would be much appreciated!

Good day, everyone!
I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.
I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the... -
So I couldn't remember my bios password and since it was broken screen, I used to connected to the TV via Type C to HDMI. So I decided to remove the Bios chip and reprogram the Bios chip with ch314a.. when I try to solder Bios on the laptop, one of the Bios leg broke off.. I bought a new blank Bios chip so I can programmed by flashing on the bios.
