XPS 13 9360, Asks for BitLocker after Update

This suggestion unfortunately does not help for me.

When can we expect the next BIOS release?

@DELL-Chris M 

I have been experiencing this problem for almost two weeks now, and have been corresponding with Dell's Japan office. However, while you said that the new BIOS "will" be uploaded, Dell Japan has repeatedly refused to answer my questions and has only vaguely responded that they are "investigating" every time. Originally, four or so day after I reported the issue to them, they suggested downloading BIOS to a USB much like the many recommendations on this forum, but with the disclaimer that they will "not take responsibility for anything that will happen." This morning, I got an email from the representative saying that they are "investigating" (again...) but they are having trouble with the investigation because they haven't been able to recreate the problem on their end, and won't be able to "guarantee anything."

I have also seen another post (I can't remember if it was on this particular thread or not) by a user who was ensured by Dell that they were "working on a solution."

May you please give us a better idea of what the current situation is? Dell Japan's replies seem very vague and unreliable, so any info you know about the current status of the fix would be greatly appreciated. 

Inaka,

BIOS 2.16.0 (XPS_9360_2.16.0.exe 13.95 MB) on the USA driver page is identical to BIOS 2.16.0 on the Japan driver page. So not sure why they think that using these instructions would not work? In fact, this Dell article, "Dell BIOS Updates", specifically has instructions for, "How do I update the BIOS using a USB flash drive?". They should be reaching out to their L3 support team for assistance. If BIOS 2.16.0 does not fix the issues, try to roll back to BIOS 2.12.0. Then keep checking the XPS 13 9360 driver page for future BIOS updates.

@DELL-Chris M Thank you! This solution may solve an issue that I have been trying to solve with Dell Japan that has amounted to a 50 minute phone call and 13 emails.

To clarify regarding the BIOS USB advice, they suggested downgrading to 2.15.1 (at my own risk), not installing the version you have suggested. The staff member I have been corresponding with is at supervisor level, and this advice apparently came from someone above him. The latest report (of not being able to recreate the error) came from Dell's "technological division" apparently (not sure about precise English title here.)

Either way, thank you, I will give this a try.

Just checking in. I have the same issue--I have an XPS 9360 where bitlocker was activated after an update. I've been monitoring this thread and another similar one. I'm guessing there are quite a few of us with this issue. My laptop is as useful as a rock right now. Has anyone been successful yet? Is anyone making headway in talking to Dell or Microsoft? I lack the technical expertise to easily understand how to revert the bios and dont want to risk trying until I know there is a decent chance at success. Alternatively, I'm considering my legal options as I'm about to incur a major loss based on my inability to access documents on my laptop. If anyone is successful, please please let us all know and post the solution in dummy terms.  Thanks and good luck everybody.

So, I checked the settings and it showed my previous installation of the latest BIOS seemed to have been successful but still resulted in Bitlocker screen, so I ended up downgrading despite the risks and it worked. However, I am very, very unimpressed about how Dell Japan office has handled this issue. After I sent them another complaint yesterday evening asking why replies seem to be different depending on the Dell office, they sent me a reply saying "There is no new BIOS right now, will check to see when the new BIOS will be uploaded!" Again, totally dodged my question.  My issue has been resolved now (no thanks to them) but I am angry that they expected me to resolve a problem they created, at my own risk. I had also been waiting on them for a solution, but after two weeks decided that dealing with them wasn't worth it, because they were generally being uncooperative, so I went ahead with taking the risk. . 

So This was the solution for me:

after downgrading the bios step by step with downloads from Dell Site (I tried every bios) still no luck.

So I downgraded to a very old one (2.6.1).
Put in a new disk.
Reinstalled win10 on the new disk (I used the Dell OS recovery tool to increase my chances)
After the new installation, windows update wanted to upgrade the firmware to 2.10.0
I don't know why 2.10.0 (probably they pulled the 2.16)

After windows update installed 2.10.0, I put the old disk back in and .... It booted.

Apparently the 2.10.0 bios from the dell site seems to be just a little bit different from the one from windows update.

Can you clarify what you mean by new disk? How did you put in a new disk but kept your old disk? I would like to try the same steps you did. Thank you.

Yes.
Install old bios. 
Take out the hard drive. Put in another empty nvme drive.
Keep the old disk because it contains your data.
Install Win10 on the empty disk.
Update bios with windows update.
Put the old disk back in.
To replace the disk: see youtube

I had a spare disk laying around. If you haven't, 500Gb is like 50$ and you can put it in a usb storage when you are done.

I am running into the same issue of being locked out by bitlocker after the BIOS update, I never set up bitlocker and was in fact unaware of its existence at all until this issue arose, consequently I don't have a recovery key and one doesn't exist when I check my microsoft account etc.

Regarding the potential fix of downloading an old BIOS version and installing it through a USB drive, do I need a program installed on the USB drive to do this or will it be able to run the downloaded BIOS from the USB drive by itself. Thank you for any help you can provide. I am only semi computer literate when it comes to unexpected issues like this. I need access to my files on my laptop etc and reinstalling windows and wiping my hard drive are not an option. 

Thanks @GuntherPelgrims for posting what worked for you as this also worked for me.

Tried to downgrade all BIOS versions down to 2.4.2 without any luck.

Followed @GuntherPelgrims by doing the following:

Downgraded BIOS to 2.5.1

Purchased and installed an empty brand new nvme SDD.

Google search on how to install new SDD if you need instructions.

Downloaded Windows 10 installation media to install windows via USB

After install, installed all of windows updates that were available and restarted until everything was up to date (BIOS was never updated and remains at 2.5.1)

Reinstalled old SDD card 

Was able to access login screen and saved my Bitlocker code immediately and backed up all of my files onto an external hard drive

Good luck to everyone else!

Great news for you @theacura. You’ve given me hope since I’m glad to hear @GuntherPelgrims  solution worked. I’m waiting for my SDD to arrive in the mail to try this out.

Regarding your last paragraph, I understand you backed up your files to an external hard drive and you can now use your XPS 13 properly. Really dumb question (and for anyone), but do you bother updating to the latest BIOS now that you have the Bitlocker code and/or disabled it?

Thanks, I literally tried every solution I could find on the forums. This one made me worried since I have never taken out the SDD. It was fairly easy and I hope it works for the rest of you. I’ll likely update to the latest BIOS now that I have the Bitlocker key.  Hope it works for you @x60643 

You can disable Bitlocker if you want.
I suggest you update driver & BIOS with Dell Command Update.
That works fine.
It's just the update through windows update that triggers Bitlocker.
If you want to prevent windows update from updating the BIOS: in the BIOS, under Security, uncheck "Enable UEFI Capsule Firmware Updates".
