I attempted to update the BIOS on my X1 Carbon type 20A7 using the bootable CD option.
The previous bios was 1.09 and I tried to update to 1.26 (file gruj23us.iso).
Booting from a USB gave me the error:
ASSERT c:\edk2\MdePkg\Library\BaseLib\String.c(166): String != ((void *) 0)
and then the update froze. The machine will no longer boot from the hard drive. However, it will still boot from USB. Is there any way to get a working BIOS back on this machine? Has anyone else seen this error when doing a BIOS update?
