BIOS UPDATE A10/ A13/ A16 XPS 15 9550 4K SCREEN TERRIBLE FLICKER

It has happened to my XPS 15 9550 4K as well after the bios update. I cannot work because of this terrible screen flickering. How could you roll back to previous version? Did you call the customer support? Thanks.

i thought i was on BIOS A09 before the update but perhaps not. The previous version to download is A06.

I had the same issue, it was infuriating. After hours of playing with settings and trying to update other drivers I had to roll back the BIOS version too. Now I have the slightly lesser annoyance of the Dell update service telling me there is 1 new update available each time I boot up.

Is there any info from Dell about this?

yep its a very amateurish BIOS release, this is the least of some peoples troubles on the 9550 machines however, others are experiences total system problems thanks to Bitlocker/ TPM issues.

I posted a pretty direct response on Dell's Facebook page and Twitter feed but no response because they just dont care.

Thanks a lot. You are right. I have installed the A06 version and the flickering is now gone. Much relieved. I do not understand why don't they just install and check it before rolling out an update for something like bios, let alone the quality testing.

Just created an account to tell that with updated BIOS I got the same issue. :(

This xps 9550 4k release had (has?) many problems since its release, looks like I won't buy blindly any high-end Dell notebook anytime soon. :(

I have had this same issue and needed to revert also to the previous BIOS version... It's a shame.

I installed this Bios update only to be faced with an unusable flickering screen, I also had to roll back to previous version and now need to live with a daily reminder I have an update available..............

Still have the screen flicker on mine, on every brightness level, its not quite as bad on full but then the fan stays on permanently. Nothing feels hot, set to passive. It seems its just one thing after another with these things. So disappointed with this model, I had to go and buy another laptop just so I can carry on working whilst this waste of money goes back for repair. Last Dell I will ever buy!! Such a shame as it had the potential to be so good, everything is there, it just doesn't work.

yep even after rolling back mine is still flickering but thankfully not very frequently, nothing like the crazy A10 BIOS.

not that its bad just now but it just seems to be happening that bit more than before I bothered to update in the first place.

still no response from dell.

it seems to me that such a situation exists for a number of reasons
recent years Dell has released a lot of new products
new products and high-tech
perhaps tight time frame customized
as a result of the product turned out to be dampish
in a hasty attempt to correct the deficiencies, to bring to mind, began to emerge's  software errors confusion and mess
we as a end-users and is seeing it now
apparently we just have to be patient
If beauty requires sacrifice, it seems that high technology needs to be served patience :)

like everything else out there I like my xps 9550
from an aesthetic point of view, it is beautiful gorgeous
I think that it will be a long time to please me even just one appearance...

It is true, it's a fabulous looking machine that I really hope gets sorted. Unfortunately, until all the glitches are cured, if they ever are, it will remain an expensive, albeit good looking paperweight. Not exactly what I was hoping for, for this sort of money.

Same issue here, rare flickering at every brightness level every minute or so.

I am not sure what was my BIOS before, but there were no flicker whatsoever. 

I think it was A09 (something with 19, maybe), how can I check?

Is there a way to roll back to a more recent version than A06?

A06 is the previous version to A10
