Bios Mods -The Best BIOS Update and Modification Source

Motherboard Manufacturer and Model: Lenovo X1 1291A11
Bios Revision: 1.72 - 19 Mar 2018
Bios Type: Award

Hello I'm hoping for an wireless whitelist removal for a fairly uncommon laptop.  I've been browsing around for the protocol to follow here so I could provide something useful to start with but many BIOS extraction tool links I see are dead.  I've run SLIC Toolkit to determine which BIOS type it is, which is Award.

One problem I'm seeing is that Lenovos BIOS updates are either packed into an exe or an oddly formatted iso so I'm not sure how to get the ROM or how to flash a modified one after.

Here is the exe version: https://download.lenovo.com/pccbbs/mobiles/8muj20us.exe
Here is the iso version: https://download.lenovo.com/pccbbs/mobiles/8muj20us.iso

Here is the screenshot from the SLIC Toolkit:


I'm subbed to this thread and will respond ASAP with anything needed to assist the process, thanks!

Dudu2002 is a BIOS wizard, up and running perfectly with a Broadcom card that didn't work before! 

If anyone stumbles upon this thread looking for whitelist removal for your original X1 you will need to make another post here requesting one for yourself as this is done on a per laptop basis and you may brick if you share the custom BIOS!

Can you help me please with bios. remove whitelist. Thinkpad x1 type1291 bios 8MET74WW (1.74 )
Thank you!

Sorry to revive this over 6 years old forum thread, but Lenovo released a new BIOS for this system in 2018 (!)

And here I was, finding this old X1 which I flattened and reinstalled, and seeing there's a new BIOS available, flashing this and then discovering the dreaded 1802. No no1802 CMOS patch working, and downgrading of BIOS is not available after updating past 1.71...

Is there a chance to let the newest one, 1.74, get the same 1802 fix? Would be greatly appreciated!

Here's the link to the ISO: https://download.lenovo.com/pccbbs/mobiles/8muj22us.iso

I managed to get a dump of my 1.74 BIOS through flashrom (at least flashrom said it was succesful, but I'm not sure). Can anyone make any sense of it?

Hi,

I am reviving and old X1 laptop and was wondering if the 1.74 (8muj22us) bios ever got modified? Also do the modified bios files allow you to upgrade if you have a faulty battery? I was hoping to upgrade the bios without having to buy a new battery.

Thanks
