Hi Guys ,

I need help regarding the Bios reflashing, newbie to this .

I own Lenovo Ideapad 330s Core i5 varaint and it was running cool till my idiotic try .

I wanted to upgrade the wifi card to dual one (intel 9260 chip), so in some forums it was mentioned to downgrading the Bios to older one will add suuport to the wifi upgrade as the current bios ver was blocking the support (after card install laptop use to stuck in the bios screen ), downgrading the Bio process crashed my laptop bios and now unable to boot to Bios or laptop.

From many forums , i came to know refalshing the Bios chip to latest official Bios will fix the problem .So i orderd the below programmer tool and it may reach in 3 weeks .

Tool: CH341A Burner Chip Writer SOP Clip Adapter

For the bios , i downlaoded the file from official lenovo website , it was in .exe format with some googling found a way to extract it to .fd file .
So the process to reflash is the below steps
1. connect the chip and erase the cureent bios
2. program the .fd file

I am following the below guide to extract the fd file

Install 7zip.
Create a new folder (eg. bios), then copy Bios.exe and use 7zip to extract the dependencies innoextract, InsydeImageExtractor, UEFITool into it.
Open cmd and change the current directory to the folder you created. (eg. > cd Desktop/bios)
Run the command > innoextract Bios.exe
Open the newly generated Bios.exe in the app folder with 7zip as archive, and then extract the files from the archive.
Copy extractor.exe, msvcr120.dll, and change the current directory to the app folder.
Run the command > extractor Bios.fd out.fd

Please advise me if i am missing any thing .

Thanks,
Karthik

@karthikblr I also have a Lenovo Ideapad 330s-14IKB with an upgraded Intel 9260, I am using the latest stock BIOS 7SCN36WW which did not block the WiFi card.

Did you make a backup of your BIOS before you attempted to flash to the earlier version? And if so how? Please don't erase your current messed up BIOS chip until you have backed it up with a programmer.

You will need to reconstruct the original (corrupt) BIOS so that you don't lose your UUID, serial number and MSDM key (Windows OEM Activation Key) - I have every BIOS released for this model and a complete BIOS dump from a programmer so it should be possible to do this assuming the corruption isn't bad.

Note that the .FD BIOS files that can be extracted from Lenovo's website are encapsulated (i.e. there is adiditional data at the start and end) so you can't just flash them straight to the BIOS chip and won't contain your UUID, serial number and MSDM key.

This laptop comes with a Winbond 25Q64JVS10 (64mbit / 8MB) BIOS chip that operates at 3.3V (spec sheet says 2.7V - 3.6V) - so don't feed 5V into it as some of the black model CH341A programmers do or you may damage it.

Thanks a lot for the reply.

Please advise me on how to go proceed with the issue.

I have not erased anything as the kit is on the way from China, the issue happened after flashing the old 7SCN26WW bios version.

The laptop just turns on with power led, the power button LED, CPUs fan in the background with no display,

I have not backed up the bios, my bad. is there any way to recover my laptop can you please guide me how to flash or repair the corrupted bios.

Thanks,
Karthik

@karthikblr Sorry for not getting back to you, for some reason I didn't receive email notifications for this thread, I am glad you got it sorted out and thanks for reporting back that the crisis recovery method worked.

Hi, I'm facing the same problems, can you guide me through the process?

I flashed my Lenovo 330-15igm bios back to 7XCN36WW after I installed the last available bios and now I doesn't turn on. I only have blackc screen and white led.

I have:

7XCN36WW.exe

bios_rel.fd file

it's an Insyde BIOS

I hope you can help me with the USB method, what I need to do more??

This is really an urgent situation, I hope you can help me. I'm really desesperate cause I need to use the laptop.

I just uploaded the previous BIOS I have:

https://www.mediafire.com/file/wp5qjkyv8...CN36WW.exe/file
https://www.mediafire.com/file/vklh323u7...ios_rel.fd/file
