Downgrade Bios back to the old 😁

 

 

Well, Dell has instructions for downgrading bios. But this one will now work.

 

Run as admin,

 

Also did the, run cmd box as administrator, then,  C:\ bios_name /forceit

 

Neither work. 

 

Unless there is a 3rd party flash software I can use? May not be safe? This last update was to cover vulnerability in CPU kernel?

 

Screen will light up if I boot without dsdt, but it runs like C#@P, and it takes over 5 minutes to boot.

 

Maybe needs a DSDT edit? HD3000 graphics set to defaults in Clover.

Thanks for the help. :)

 

LCD lights up, but it's a bit buggy.

Sometimes boots up like I would expect. 

Other times,  it takes longer to boot, and then when it reaches desktop it has brightness all the way up, there is no brightness control in  Preferences >> Displays, and Icon for dual-monitors is showing like there is a projector or another monitor hooked up.

Then it can take anywhere from 1 to several reboots to get it to boot to normal desktop.
