Dell E7440 macOS Catalina bluetooth, Battery status, debug generator and weak problem

[dctacsi]

Hello,
I made a new installation for Dell E7440 based on the following description:

https://osxlatitude.com/forums/topic/8506-dell-latitude-inspiron-precision-vostro-xps-clover-guide/?tab=comments#comment-94956

 

For installation I used "Clover_v2.5k_r5102" and the following Bootpack:

After installation, I did the following:

Post Install:
Kexts inside /EFI/Clover/kexts/Other/CopyToLE are to be copied to /Library/Extension
Repair permissions and rebuild cache
    sudo chmod -Rf 755 /L*/E*
    sudo chown -Rf 0:0 /L*/E*
    sudo touch -f /L*/E*
    sudo kextcache -Boot -U /

 

For now, it looks like almost everything works except:

 

- WiFi works fine, only Bluetooth doesn't.
    I tried to do it based on the descriptions, but so far it looks like it doesn't work.
    Here's what I tried:
    I have downloaded “BrcmBluetoothInjector.kext”, “BrcmFirmwareData.kext”, “BrcmPatchRAM3.kext” from the link below.

    https://github.com/acidanthera/BrcmPatchRAM

    I then copied these files to the "/EFI/CLOVER/kexts /Other/" folder and to the "/Library/Extensions/" folder, running the following commands:

    sudo chmod -Rf 755 /L*/E*
    sudo chown -Rf 0:0 /L*/E*
    sudo touch -f /L*/E*
    sudo kextcache -Boot -U /
    I restarted my computer, but I still can't see the Bluetooth device.

 

- Battery status is not updated
    The percentage decreases and increases as needed, but the symbol does not change depending on whether it is plugged in or not unless I restart the computer.
    It worked perfectly under Mojave.

 

- If I close the display, the machine goes to sleep as it should.
    Then, when I open the display, the computer starts up, but the display does not turn on unless I press a key.
    Is there a setting for this to turn on the display automatically or is it not workable?

 

- I wanted to attach a debug file, but unfortunately I couldn't create it.
    Here's what I tried to create:
    I downloaded the file from: https://osxlatitude.com/forums/topic/10209-how-do-i-generate-debugging-files/

    I unzipped it to the Downloads folder.
    I opened a Terminal and ran the following commands:

        chmod a+x ~/Downloads/install_tools.sh
        ~/Downloads/install_tools.sh

    Unfortunately, it ends with the following error: "/Users/blasio/Downloads/install_tools.sh: line 54: gen_debug: command not found"

    Can you help me out on what's wrong?

 

Thank you in advance for your help!

What wifi/BT device does it have?

Add to boot arg the following

darkwake=0 abm_firstpolldelay=20000

[dctacsi]

DW1550

[Jake Lo]

Try this, remove SSDT-UIAC-E7440.aml

In Config file, enable the 2 USB Port limit (10.15.x) patches

 

For debug, follow the following FAQ

 

[dctacsi]

Which of these should I enable?

okay

I did everything.

- Bluetooth works perfectly, this is solved by moving 3 kext to /S/L/E folder.

- Waking up your laptop works the way I want it to!

Thank you for your Jake!

 

But two things still don't work:

- Unfortunately, the battery status is still unchanged.

- Unfortunately, I still can't create the debug file. The mistake is still the same.

 

Can you still help with these?

Try different settings for abs_firstpolldelay

https://github.com/RehabMan/OS-X-ACPI-Battery-Driver

 

if that still doesn't work, try replace FakeSMC + ACPIBatteryManager with VirtualSMC.kext + SMCBatteryManager.kext

So far I have not achieved anything with battery status, but I have a bigger problem.
If I remove the "SSDT-UIAC-E7440.aml" file, when I plug in any USB device, it says "It requires a USB power supply".
But if i put it back then bluetooth is not available ...
