<< Solved >> Trying to upgrade from El Capitan "still waiting for root device"

[PatrickH123]

Hello, I am trying to upgrade from El Capitan to Catalina. I was trying to follow the following guide: https://www.tonymacx86.com/threads/update-directly-to-macos-catalina.284463/, but I got stuck at booting the Catalina installer. I updated Clover to the latest version as well as FakeSMC and Lilu kexts. When booting the installer at first it froze at the following point:

After adding SSDT-EC.aml to my Clover folder, I was presented with the prohibitory symbol:

"Still waiting for root device", which usually indicates that my drive cannot be seen by the OS, however I do not have this problem when booting El Capitan and I have AHCIPortInjector.kext in my Clover folder. And I am not using any USB drive since this is an upgrade and not a clean install.

Is there anyone that can help me?

Thanks in advance

Update: I decided to prepare a Catalina install USB to try to reinstall the whole system. But surprisingly I was able to boot into the installer without problems and upgrade my existing El Capitan install to Catalina! After fixing multiple issues such as audio and brightness, I am now left with just one issue. When I plug in an HDMI cable, the system reboots. I am using a modified config_HD615_620_630_640_650.plist and have tried to activate the framebuffer patches, but the system still reboots when plugging in an external monitor. After this I tried to change the platform id to different values and set all connectors to hdmi using Hackintool, but when I export my config and reboot, I only get kernel panics.

What can I do to fix this?

Attached below my clover folder that currently allows me to boot but without external HDMI working. Lilu and WhateverGreen are installed in /L/E

delete AppleBacklightFixup.kext this shouldn't be needed with latest version of whatevergreen.kext

move Lilu, Whatevergreen and AppleALC.kexts to clover/kexts/other

then re run in terminal:

sudo kextcache -i /

and reboot your laptop
