Just curious, I was able to successfully (albeit maybe not very intelligently) read the flash chip on my lappy twice, and it read successfully. However, since the x220 is not "officially" supported by flashrom I has to use laptop:force_i_want_a_brick. 

I'm curious if anyone with the x220 has reflashed coreboot (multiple times even?) on their x220 and not had any issues. I thought I read somewhere that since the firmware is unlocked it was safe to do, though I could have been reading something for another laptop.

Thanks!
