We really need to start warning people when the flash a thinkpad that it is very important to save the old flash image.
It is somewhat thinkpad specific whether the bios extracted from the update tool will work. On X60 I have had no success with it.
On X200 it sort of works to flash the vendor bios extracted from update .exe. You can even just flash bios region and leave ifd, gbe (and me) alone. (Though I have had it not being able to boot and complain about some pxe stuff)
Note: on x200 there exists a modified (whitelist removed) bios which does not write protect its bootblock. With this it is possible to flash the vendor bios without having to rely on an external programmer to re-flash coreboot.
Backup are essential!
