Dell 7470 bios issue

A new bios update came out for the 7270/7470 laptops. The 7270s updated fine but the 7470 will not update. It just immediately reboots into Win10.
Ive tried all available methods and it wont update. It presently has the 1.27.3 bios and would be going to the 1.31.3 bios. I also tried installing the 1.30.3 update to see if that would work but it doesnt install either. For some reason the 1.27.3 bios appears to be the one.

I assumed since the 7270s updated from 1.27.3 to 1.31.3 with no issues that there was something wrong with the 7470. That wasnt the case as I found three other bios all marked urgent prior to the 1.31.3 bios. I started with the oldest and worked my way up to the 1.31.3 update and it was fine. The 7470 needed to have the other bios updates installed in order before the final one could be updated. Everything is fine and just a word to other Dell laptop users if they are having issues as well. It would have been nice if Dell had mentioned they were required before the final bios could be installed.
Im more curious as to what the difference is between the 7270 and the 7470 that allowed the 7270 to be able to go right to the final update.
