dctacsi Posted November 15, 2021 Share Posted November 15, 2021 Unfortunately, I need some more help. The update went smoothly, but when the laptop tried to turn on while the system was loading, the status bar stopped at half load and did not continue. I suspect something is wrong with EFI, but since the system is not loading so I can't turn on text boot mode. Does anyone have any tips on what I'm going to ruin?

Moderators Jake Lo Posted November 15, 2021 Moderators Share Posted November 15, 2021 you can try my bootpack in my E7440 guide. You might have to make some adjustment depending on what wifi/bt device you have. most likely you need to disable BTinjector and replace it with BlueToolFixup.

Moderators Jake Lo Posted November 15, 2021 Moderators Share Posted November 15, 2021 ok, that's what I have as well. I have BluetoothInjector MaxKernel set to 20.9.9 so it won't load on Monterey on my OC 0.7.4 bootpack. You'll just need to enable BlueToolFixup.kext in the config file but BT is not quite working in Monterey at the moment anyway. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 15, 2021 Moderators Share Posted November 15, 2021 just disable it but in my bootpack it's set to only load for Big Sur and below so it won't affect Monterey so it's up you if you want to delete it or disable it. if you delete it, make sure it's remove in the config file as well.

dctacsi Posted November 17, 2021 Author Share Posted November 17, 2021 I just made the exchange. For now, everything is going the way you said, I no longer see Bluetooth under Big Sur. Now I do a Clonezilla backup and then I try an update. For now, do I understand that I don't have access to Bluetooth under Monterey? (Thank you for your help so far!!!)

Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 If you are still running BS, then enable bluetoothInjector. Just set the MaxKernel to 20.9.9 so it won't load on Monterey which causes hang. And add BlueToolFixup.kext to load BT for Monterey, but set MinKernel to 21.0.0 so it'll only load for Monterey and up. Even with BlueToolFixup.kext, BT may or may not work. Still in development.

dctacsi Posted November 18, 2021 Author Share Posted November 18, 2021 Thank you very, very much for your help! Eventually I had a hard time (due to my incomplete English knowledge) understanding what to do and the update went perfectly! Finally, even after the update, even Bluetooth works perfectly !!!
