I am having the same problem.  I am also unable to turn 'secure boot' off.  In the bios, I can select 'disable' for the secure boot option.  I save and restart.  Everything looks ok until I get to the boot screen (by pressing F12).  It says that secure boot is 'on.'  What?!  I can't boot a Linux live USB anymore and this is unacceptable.  Also, I am unable to downgrade my bios to the previous one from 1.2.4.  I was hoping the bios 1.3.0 would fix this problem but I can't install it.  Alienware, please fix this.  Thanks.

I am having the same problem.  Blue screen reboots haven't happened in a while, but keeps telling me I need to update and wants to replace the same file.

Think there will be a resolution to this anytime soon?

I have the Alienware 17 R4 with the same problems everyone here is having if you look at the file name in the older versions. The one with URGENT next to it SKL1.2.4_KBL1.2.4,1.2.4 see in the file name it says 1.2.4 to 1.2.4 i can kinda see it. But the one they want me to download by default SKL1.3.0_KBL1.2.4 ,1.3.0 looks like its going from 1.3.0 to 1.2.4 but neither work for me. I am trying a lot of different ways or running the 1.24 to 1.24 , oh and by the way the file name might be the same but if I run msinfo from windows mine has a BIOS date of 1/25/2018 the version with URGENT the 1.24 to 1.24 one has a date of 5/23/2018 so they don't look like the same file. I hope this information can help one of you realize something I'm not seeing so we can get this updated because I have been really annoyed I want the newer version
