High Sierra Dos Dude Install Issue

[duncanlovett]

Hello, I have been using Dos Dude's High Sierra on a MP3,1 for quite a while. The other day I stupidly allowed an Apple software update to take place and when it rebooted the mac thought the wifi card was missing. I managed to fix that using

but upon restart it had a kernal panic and took a few restarts to get it going again. I am now without the wifi again and re-applying it doesn't work. Each time I reboot not I get a message telling me that I have SIP installed.

I cannot reboot from the recovery partition as it doesn't not seem to be there. You can select 10.13.6 recovery partion by holding apple option, but it does not boot.

I cannot get the mac to boot from a usb installer disk to re-install high sierra.

I am currently partitioning my main boot disk and will try cloning the the boot system to the new partition and see if I can then turn off sip suing that.

Any ideas on how I can restore the recovery partition, turn of sip without a recovery partition or boot from a usb so I can re-install everything?

Many thanks in advance for any ideas.

UPDATE
Partial Success....

I though as I have a working 10.13.6 drive apart from these issues, I could partition a 8GB part of it, and use that to run the installer/patch from. I made an *GB partition in disc utility, named it macOS 10.13.6 Installer.

I then ran Dos Dude's High Sierra patcher from the main HD. Selected the installer partition and let it install, which happened very quickly.

I then rebooted, held down option and selected the installed volume.

The install cam up and I ran the patch updater, rebuilt the caches and rebooted.

This gave me 10.13.6 with working wifi!!!!

I then rebooted held down option and selected the installed volume. This time I ran terminal and used the csrutil disable command which ran with no errors. Restarted the machine and held down option and selected the main macos 10.13.6 boot volume.

In terminal ran csrutil status, which confirmed SIP is off. This was also confirmed in the about this mac system report.

However, I still cannot boot the mac from a USB installer/patch disc as it does not show up as a boot option.
I also have no recovery partition, do I will leave the main drive partitioned and the macOS 10136 Installer volume there as an emergency backup.

Any idea on how I would re-create the recovery partition and why it will not boot from the USB recovery drive?

Thanks in advance for any ideas and I hope this helps anybody else with similar issues.
