bricked laptop needs bios reflash

Hey,

unfortunately I have to deal with UEFI Malware which the bios updater from Dell does't remove. To fix this I need to reflash the rom to the SPI chip, I'm using a CH341A mini programmer for the job and got it all hooked up just to notice that I can't get the file I need out of the .exe. Is there any way to get the recent .bin? An older one would suffice so I can use the dell updater tool after reflashing that to catch up to current.

thx in advance
