[REQUEST] Dell XPS 15 9550 BIOS Unpack

[ismart]

Hi mates,

Can't get my Dell XPS 15 9550 laptop to go pass through a black screen though fans are spinning.
I suspect faulty bios and would like to force reflash it.

Based on this forum thread

I have to extract .ROM and .HDR files from XPS_9550_1.4.0.exe and store it to USB flash to proceed a reflash procedure.

Can someone help me?

I tried /writehdrfile  /writeromfile but couldn't get the files.

Hi!
This is your .hdr file.

Can you please provide the .rom file as well? or ateast guide me how to do it myself.Existing methods doesnt seem to work on this EFI bios.

I'm not sure but isn't .ROM file required as well? 
Thanks for uploading .HDR file but can you also upload .ROM ? How do you do that? Most methods provided for Windows do not work.

May I know what program you use to extract BIOS.exe file?
CMD command "/writehdrfile /writeromfile" on windows 10 do not work.

Bump, update. The issue is not solved yet.

Hi ,

in the XPS 9550 2016/2017 is not possible to flash a "ROM" file anymore ,or at least not this extension . If you got stucked in the BIOS 1.6.1 ,no worries, you can downgrade to any BIOS version ,check carefully this tutorial ,it´s really simple and easy : https://github.com/wmchris/DellXPS15-955...upgrade.md

For the XPS 9550 2016 model , in my case , the perfect BIOS that works really smooth and all the Intel technologies are working fine is the BIOS version 1.5.1 .
To find old BIOS it´s easy , just google "XPS 9550 BIOS 1.4.0" or "xps 9550 BIOS 1.2.25" , depending on the version you are looking for .
Thanks to that tutorial now is possible to downgrade to any BIOS you like ,check which fits you more ,but for Windows 10 users i recommend 1.5.1 , is more stable and works really fine . I know is a pain in di ars all this, i searched everywhere... not even on the Dell website is coming the solution.... i am wondering how this guy knew about this solution...or maybe is an old method and i didn´t know...anyway, the point is that if 1.6.1 gives you problems, go back to 1.5.1 . 1.4.0 i saw it a bit faster in the start up , and 1.2.25 a bit faster too, but it might not go too smooth with Windows 10, so if you wanna avoid black screens and blue screens and all this, better go for 1.5.1 that is really stable . If you guys need to ask more questions, i am here to reply anytime. Cheers and good luck with your XPS 9550 ,enjoy it !
