I reported this issue to pro-support already, waiting for the fix to be released.

The February 9th 1.4.1 is definitely a new version. I flushed it and not only it updated firmware for some of the devices, it also fixed a laggy/skippy bluetooth issue that I got from the "earlier" 1.4.1 BIOS...

Dell really need to get their act together. This is frankly yet another embarrassing stuff-up which should have been fixed (i.e. quickly rename the new version as 1.4.2) within a few hours of it being reported here.

The file, XPS_13_9300_1.4.1.exe, which I retrieved on Dec 10, 2020 has MD5 = a45fe28eb5b30189b8de804d71ab3868.

The Dell web site, says that the Feb 9 version of that file has the same MD5.

Then it must be the same BIOS. I definitely still remember this number from a few days ago when I reflushed 1.4.1 on my laptop. This is really weird. When I first installed 1.4.1 long ago, it definitely gave me some errors during flushing (said that some of the firmware could not be updated). I also had more frequent bluetooth glitches after that (although this might be subjective, or unrelated, as I use different sets of devices over time). The recent update went on smoothly and updated firmware for several devices (though said some of them were already up to date). So maybe under some circumstances, it fails to flush properly and may have to be run twice/several times? Aren't we all excited about this guessing/investigation game Dell makes us play?

Using "cmp", the .exe file I retrieved on Dec 10, 2020 (and which is on a thumb drive) is identical to the file I just retrieved again in my Downloads folder.  I'm waiting for Dell to straighten this out.

How can you guys possibly think the 2 x 1.4.1 releases are the same? Look at the new release notes <ADMIN NOTE: Broken link has been removed from this post by Dell>. At the very least, the newer 1.4.1 release on 09-Feb-21 includes a fix for Intel Security Advisory INTEL-SA-00455 which was released earlier that same day. Also, I updated the  new 1.4.1 over the 1.4.1 I installed in early December and although many/most components did not change, at least 2 of the components did update. @emapex must simply have made a mistake comparing the MD5 sums.

Well, according to @emapex md5 and cmp produce same results for the two files. So the files are the same. It may be that, as it was in my case, it takes more than one flushing to properly update all the firmware though...

Definitely the same file. Support was also not believing me despite me sharing that the checksums were the same, this was the proof that they accepted that there was indeed an issue:

The file was signed in November... They still haven't provided any update though.
