Hi Terry

We're running Windows 11, and have put off the July update pending resolution of known issues with July update KB5015814, which I think may be the equivalent of your KB5015807, but while researching, came across this which might help:

https://ugetfix.com/ask/how-to-fix-kb5015814-fails-to-install-on-windows-11/

Thank you for the suggestion, Argentum

I've tried fixes 1-6, to no avail. A notable result is that when I opened optional features to disable .NET, the optional features list was empty. I don't know what to make of that. I can give you a more detailed rundown of the results of fixes 1-6, but I don't want to overload you with the details unless you really want to see them.

I'm now on Fix 7.  I've manually download the update, but it's too late to mess with it tonight. Tomorrow is another day.

Hi Terry

Is the Windows Modules Installer service running? This might explain why you have no Optional features showing.

Another way you might get optional features to re-appear is creating a new Administrator account.

Are you experiencing any other adverse symptoms on the device that might help pin-point the issue?

-----------------------

As far as the update is concerned, the only other thing I can think of is waiting for the August cumulative update, and seeing if that will install.

Otherwise, it does seem like at this point you've already exhausted  the (very limited) things I can think of besides the dreaded - for me, at least - Windows Reset.

Thank you for responding again. I tried the things suggested in that link, but none worked. I rebooted into safe mode to see whether any of the problems went away, but they didn't. I tried recovering my computer using a different backup, but that failed as well.

I decided to hold off trying to install the update from the downloaded file in favor of contacting Dell support directly. If there's one thing I've learned from years of computing, it's that "You can make it worse."

Then, I decided to try doing a system reset one more time, using SupportAssist, even though it didn't work last time I tried it. I discovered a few fine-print settings that I hadn't noticed before. I set them, and the reset seems to be proceeding. It's a lengthy process, so I won't no whether it worked until morning. If it fails, I'll call Support.

Thanks again for helping.

The saga (i.e., nightmare) continues. Windows successfully reset and updated, but I can't recover my system from any of my backups, which is something I will have to take up with Acronis. HOWEVER, I also haven't been able to  get the system to boot from an external DVD drive (the Vostro has no internal DVD drive). I press any key to boot from the DVD, but it just continues its merry way and boots into Windows. I don't know whether this is a Dell issue or a Windows one, but it's sure getting annoying. Things that used to be really simple are now complex and problematical. I blame that on Microbloat.

good post like it

Have been getting this error for the past week (20/1/24). Dell, Inc. - Firmware - 0.1.30.0 Install error - 0x80070002

I've been receiving this error for over two weeks, with no solution in sight : someone at Dell should contact Microsoft to handle this situation since its inevitably not self correcting especially with all the solution suggestions posted (with appreciation) . Please, some one help us with this ,

I am having the same problem on a Precision 3640 - has anyone found a fix?

I am having the same problem on a AIO Opti[lex 5260.
