[REQUEST] Lenovo ThinkPad X1 (8METxxWW) Whitelist Removal
#31
(02-23-2021, 09:21 AM)blae Wrote: 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? Smile 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
