Tomato / Tomatoe in this case. Yes they had a UEFI update that botched system. Nothing will load stuck on the TPM and Keys screen.
Bluegrass - Yes Microsoft pulled the updates from what I saw on TechNet.
As of today I still have a dead Surface due to UEFI failure. Microsoft cant even seem to tell me when I am going to get a new one even though I choose the advanced replacement option which meant I would have a replacement in 3 days!
