Cannot boot High Sierra installer - "Still waiting for root device" issue

[TheFancyDinosaur]

I am trying to do a fresh install of High Sierra 10.13.3 on my XPS 13 (9350) but I am having issues booting the installation. In Verbose mode it crashes half way, a "no entry" icon pops up and the last text says "Still waiting for root device".

I followed all the instructions one by one. I tried it in multiple USB drives and different ports; tried creating the installation drive with Unibeast and Terminal command; tried the latest and previous Clover EFI bootloaders.

My configuration is:

• Intel i5 6200u Skylake
• 8 gb RAM
• 512 gb Nvme M.2 SSD
• DW1830 Broadcom Wifi card.
• Current BIOS is 1.6.1

Here are the screenshots of the verbose right before and during the crashing: https://imgur.com/a/flaDj

Hello, could you please provide your Clover/ACPI folder? (I want to check the original ACPI tables under Clover/ACPI/origin.

Here it is, hopefully you get to find the problem. It seems like I am not the only one having this issue and it is very common.

@hebert1410 try removing the SSDT-XHC.aml, for the wifi driver and try to boot to desktop. According to you screenshot it crashes at the wifi module initialization!

@hebert1410 I solved the problem adding USBInjectAll.kext https://bitbucket.org/RehabMan/os-x-usb-inject-all/downloads/ into the Clover/kexts/Other directory. I was able to get to the installer, prepare the ssd and start the installation.

After the first reboot i got an error (something like "Service exited due to signal sent by security"). I just booted again an the error was gone, and the installer finished its job.

Unfortunately i get a Kernel Panic while booting High sierra from the SSD and I haven't found a solution yet.

My config is :

• i5 skylake
• 1.7.0 BIOS
• FHD video
• 256 gb ssd
• dw1830 wifi

And i've used rehabman's clover fork to prepare the usb. Hope this helps!

EDIT: I finally solved the kernel panic and managed to complete the installation! I did some minor changes to the clover folder in the repo, but i think the one that did the trick was changing the smbios from macbook13.3 to macbook13.1 (not sure why it worked, maybe because i have the non-iris model)

anyway here's my final clover folder CLOVER.zip

Thanks for your Clover Folder!!!, it seems everything works good but the Wifi,mine is DW1560 and it used to work well in 10.14.1.but now I can't use it. do you have some advices?

@Scared-Heart Hi, I'm glad that my Clover folder has worked for you! As for the wifi issue I'm not skilled enough to give you a solution, but it seems that you need to "either inject compatibility in DSDT or patch the Brcm4360 kext to inject your card's ids (former is somehow easier than latter)." link to the post where i read that

I know this is not much of a help but as I said I'm not a hackintosh guru.
