Works mostly on the cheaper APTIO bios updates.- I tried extracting the Bios from the "5430A18.exe" file using the /writehdrfile and /writeromfile flags, but got errors and it didn't work.
SPI Flash is protected after bios runs.- I used "Universal BIOS Backup ToolKit 2.0" to try to backup my Bios to a file. I ended up with "DellInc.-A18.rom", which is 14MB. I attached it to this post.
This is then only temporary. If it should work Computrace comes back after bios update.- I then used "UEFITool_0.22.4_win" to try to edit the Rom. I found 2 Computrace modules, and a lot a Computrace references in "SetupPrep". The modules were easy enough to remove, but wasn't sure if I should remove SetupPrep or leave it. I don't know enough to edit it. I decided to leave it.
You need an external flasher like SVOD/SVOD2/RT809H/RASPI- I got stuck when it came time to try to flash the Rom file back. Dell has no separate flash utility for Rom/Bin/HDR files; their Bios files are all EXE. I tried a few flashing programs, but they all said my Rom was an invalid file.
My Granny has used dellbiosreset.iso- From the video I posted above, it looks like they were able to circumvent CompuTrace by using "dellbiosreset.iso" to wipe the service tag. The E5430 appears to be too new for this tool to work, and I haven't been able to find another way yet to change or delete the service tag.
