HP 840 G3 EliteBook ** WiFI and Bluetooth resolved** Monterey / Big Sur

[Donw35]

@Jake Lo Mad props to ya sir, I was going to build a boot loader for my G3 (haven't had time to get to it) and saw your EFI, excellent job man. worked. I may do a little tweaking but I don't think I need to do much...

 

I am going to add this to the 1st post and give you the credit

@Donw35

Thanks. Actually it can be updated a bit. We no longer need VoodooI2C.kext to enable the internal drive, just add ctlnaAHCIPort.kext instead. Multitouch gesture can be added to the 840 G2 as well with the same 2 kexts (VoodooSMBus + VoodooRMI). You just need to add the device id to VoodooSMBus. For the 840 G2, it's 0x9ca28086

I had posted the edited files here

@Jake Lo

Good work, I updated OC to .6.1.0 and the latest Lilu.kexts and WhatEverGreen.kexts as well. I did some other changes in the config plist and remove the OPenCore boot picker to builtin so the Reset NVRAM is easy to get too.

 

[Jake Lo]

You could also access it by pressing the spacebar at the Picker or change HideAuxiliary to NO so it'll always display

@Jake Lo Can you please share the sources (.dsl) of your SSD-840G3.aml?

I have a 850G3 and although on paper it's the same machine (except for the screen), but I found out that sometimes components do differ.

Same Skylake model with HD520?

Yep, same model.

 

Thanks

 

Currently the laptop is configured with Rehabman's Hotpatch-Clover method. So if I ONLY use what's used now, would that be enough?

If you're using SSDT-8x0G3b.aml, then most likely my OC files will work for you too, otherwise you just need to replace the SSDT's name

[Benjamin Franklin]

Thanks Jake

Credits go to Jake Lo for creating this EFI file. I did make some changes to his, this one is Open Core 6.1.0 and latest Lilu.kext and WhatEverGreen.kext

I checked the upladed EFI with my HP 820 G3, and Big Sur Beta 8 works perfectly.

Thank you very much.

Multitouch gesture on the 850 G3 works with: VoodooPS2Controller (by Acidanthera) + VoodooSMBus + VoodooRMI

For OpenCore disable the VoodooPS2Controller plugins: VoodooPS2Trackpad VoodooPS2Mouse and VoodooInput (just the one in VoodooPS2Controller)

Put VoodooPS2Controller (and keyboard plugins) before VoodooSMBus and put VoodooSMBus before VoodooRMI

For OpenCore disable the VoodooRMI plugin: RMII2C 

 

Question: has anyone been able to get the little stick on the keyboard ("The {censored}") and the buttons directly under the keyboard (and thus above the trackpad) working?

 

Edit: for the censored word one can also read “gnome nose” ;-)

Thank you, this works perfectly on EliteBook 840 G2 ! I successfully updated to the latest kexts.

[Donw35]

Here is my recent EFI folder with OC .0.6.3 and latest kexts...

[Benjamin Franklin]

Any changes in your config for the latest (the non beta) release? 

[maxb2000]

Anyone has DW1820A ? I don't have 5 GHz band at all and 2.4 GHz only runs on 20 MHz.
