In my case, it provides this output:
So I can see that the USB is at /dev/disk2, time to format it. (Be sure to change the path according your flash drive)
Download macOS Big Sur from the Mac App Store, after the download process has finished, now create the USB Installer by opening terminal and writing the following command:
/dev/disk0 (internal): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme 240.1 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_APFS Container disk2 239.8 GB disk0s2 /dev/disk1 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +239.8 GB disk1 Physical Store disk0s2 1: APFS Volume macOS 58.9 GB disk1s1 2: APFS Volume Preboot 43.7 MB disk1s2 3: APFS Volume Recovery 509.7 MB disk1s3 4: APFS Volume VM 20.5 KB disk1s4 /dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *30.8 GB disk2 1: Microsoft Basic Data ERIN 30.8 GB disk2s1

sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/install_osx /Applications/Install\ macOS\ Big\ Sur.app --nointeraction
2. Copying OpenCore Folder Contents
Copy the EFI Folder linked on my GitHub to the USB disk which should be labelled as "install_osx"(If this is your first installation) or to your existing EFI partition.
3. Editing the config.plist
Edit your MLB, SystemSerialNumber and SystemUUID with ProperTree or OpenCore Configurator. You can also use GenSMBIOS to generate this data.
4. Post Install
Use Hackintool to fix hibernation and for USB port patching(If required).
Add DPI controls here.
Install the YogaSMCNC app & YogaSMCPane from the YogaSMC-App-Release.dmg (This gives you additional controls under System preferences).
I always recommend the vanilla install method. The best guide for this is here.
