macOS Catalina 10.15.4 (19E287)
Update went Fine
I was finally able to get my Catalina installer to boot using by changing EC0 to EC 4543305f 45435f5f. Huge headache with this as it took me a good couple of days to fix the error.
The good news is I can make it to the installer but now the problem is now the Catalina installer gets stuck at 2 minutes with the error code showing disk25s1 is not convertible to APFS.
My Troubleshooting Steps:
- Tried another NVMe drive, with same results
- Checked Samsung Magician for updates, no luck
- Formatted the drives in Ubuntu, same exact installer error.
For some reason the disks always show as "Writable: NO"
- Asus Z390-E
- Intel i7 9700K
- Samsung 970 Pro
- 16GB Crucial
- Intel UHD Graphics
Is there something wrong with my kexts or config?
A few days ago I faced a problem - installed ocquirks and it somehow broke my prelinked kernel. System won't boot then, and I spent more than a day restoring from the netatalk backup to copy working prelinked kernel directory from the backup to the s/l
So, my question is - how to relink prelinked kernel without that? I found boot args -f UseKernelCache=No but it didn't work. I was able to boot to the recovery, if that can help.

I decided to extract the immutablekernel for Catalina 10.15.3.
I had to add a FAT header but it extracts just fine.
Thanks to this we have the kernel and kexts for the immutablekernel.
The info dictionary and lists are also included.
Needs further study if it contains extras compared to the prelinkedkernel.
Maybe we can find out what those .im4m files (for example immutablekernel.x589iclydev.im4m) are thanks to this.
