  1. Done. Still no luck, but I noticed this (Invalid Parameter error from BlueToolFixup.kext) during startup (not sure if it was there before):
  2. It works as expected in Windows, even after sleep.
  3. I attached my OC folder... I have all of those installed, yet my Bluetooth isn't working. Nothing happens when I try to turn it on in System Preferences or from the top menu. It does show up under USB though: OC.zip
  4. Hello, Even though I no longer have a Broadcom card in my Monterey 12.2 Dell Latitude e7470 system (replaced with Intel 8260), I can still see a NULL Bluetooth controller that I do not want, as I suspect it's preventing my Bluetooth from working. What exactly is injecting this and how I prevent this from happening? I attached my OC folder (AirportItlwm.kext, IntelBluetoothFirmware.kext, and IntelBluetoothInjector.kext have been removed from the upload due to excessive size). Thanks! OC.zip
  5. Hello, I have a similar issue with the 8260NGW. Have you tried toggling Wi-Fi off, and then on? One temporary workaround is to disable sleep. Also, IntelBluetoothInjector.kext should be disabled in Monterey: https://openintelwireless.github.io/IntelBluetoothFirmware/FAQ.html#what-does-this-kext-do
  6. Update: I replaced the DW1820A card in my laptop with the Intel AC-8260 card that came with the laptop along with the necessary Intel Wi-Fi/BT kexts and it is working fine. The DW1820A was previously working fine, even without disabling ASPM in my case... This all started right when I upgraded to Monterey 12.1, so I strongly urge those thinking about updating to 12.1 and above to make a backup.
  7. @Jake Lo It didn’t create an “OpenCore” boot option. I also tried resetting the BIOS to defaults and reflashing, but no difference.
  8. @Jake Lo Still gets frozen at the mbinit: done line, even after resetting NVRAM
  9. Thanks! It's injecting successfully now. However, whether or not I'm enabling the kexts AirportBrcmFixup, BrcmFirmwareData, etc., it's now freezing at the same point as in my last thread: https://osxlatitude.com/forums/topic/17059-e7470-not-booting-after-updating-to-monterey-121 If I revert to the original configuration, it takes 5+ minutes to boot with multiple "PXSX stalls".
  10. I believe the device is still named PXSX in my case, even if AirportBrcmFixup is enabled, when I checked under IORegistry Explorer. Also, I am still getting the same error... Have I declared it as External correctly?? DefinitionBlock ("", "SSDT", 2, "ARPT ", "BCM4350", 0x00000000) { External (_SB_.PCI0.RP05, DeviceObj) Device (_SB.PCI0.RP05) { Device (PXSX) { Name (_ADR, Zero) // _ADR: Address Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { If ((Arg2 == Zero)) { Return (Buffer (One) { 0x03 // . }) } Return (Package (0x0C) { "AAPL,slot-name", Buffer (0x05) { "WLAN" }, "compatible", Buffer (0x0D) { "pci14e4,43a0" }, "device_type", Buffer (0x08) { "AirPort" }, "model", Buffer (0x24) { "Dell DW1820A 802.11ac Wireless Card" }, "name", Buffer (0x10) { "AirPort Extreme" }, "pci-aspm-default", Buffer (One) { 0x00 // . } }) } } } }
  11. Apologies, that syntax error was made in the process of removing my serial number, etc. I have tried using an SSDT file instead, (adding it to config.plist too of course) but it is not loading/patching correctly at boot either, with an AE_ALREADY_EXISTS error: SSDT-BCM4350.zip
  12. Hello, I'm having an issue where a DeviceProperties patch doesn't seem to be injected, as when I look at the device under IORegistryExplorer, not even the pci-aspm-default is changing nor is the device associated with a kext... Perhaps this explains the startup issue related to the DW1820A that I brought up in an earlier post, where my system often doesn't boot or takes 5+ minutes (stalls at PXSX), unless I disable Wi-Fi or boot out of luck. What could be causing this? Thanks! config.plist.zip
  13. Still no luck... I tried booting with "-x" and "cpus=1" as well, but it ended up at the exact same point as last time. So I went ahead and tried booting with all the wireless features disabled in BIOS and sure enough, it booted. However, when I tried booting ahead with the wireless features re-enabled, it's booting up successfully again. The only thing I did was turn off and on the wireless in BIOS.
  14. Done. Sadly still not much progress, although it’s slightly different?
