Stuck on enabling hidden 4g decoding

[ArchOcean1]

i don't understand what i should do after i downloaded IRFExtractor can you help?

[MrAnonymous7122]

The guide on enabling hidden 4g decoding was recently updated.

Did you get any further? Im also kinda stuck on that 4g decoding step as well. I have no knowledge of how to do this stuff, but i postd on win-raid some info: https://winraid.level1techs.com/t/dell-precision-5820/101490 basically looking to enable rebar on an older dell precision 5820. I included the lates BIOS update file and was able (i think) to extract bin files, but i end up with a bunch of different bin files. Any help would be greatly appreciated.

Which step of the guide are you still on?

[janstadt]

Sorry, i should have been more clear. Thats the bio exe that i downloaded from dell. The other files are what is extracted.

@MrAnonymous7122 Would you be able to download that exe file i included and see if you can poke around to determine if its even possible to do all this? Would really love to get this all figured out.

Also, i see a name @zhiwoo listed in the known working flashes but i cant find them anywhere. I see they flashed a Dell 5810 and i have a 5820 so i am hoping its something that is achievable.

I'm not really an expert on OEM bios files, it's possible the updater only contains code to download the bios directly from dell. Seeing as it is an OEM, it's worth looking at a physical hardware flasher which can read and write directly to and from the bios chip. From there you can edit the current bios and then reflash the updated one.

we own a dell 7920 and a 5820. We'd like to modify the bios too. Did you have any success with your dells?
