device is write locked

Question

System Specs

cpu: AMD FX-8150 8 cores

Motherboard: ASRock 960GM VGS3 FX

2 500GB sata hdds

8 GB of RAM
Graphics AMD 760G "Integrated"
Network Qualcom Atheros AR8151

So I get stuck at Missing Bluetooth Controller Transport   while trying to boot to the installer
 

and I ran these commands using the -s boot flag:

Type: mount -uw /
Type: cd /System/Library/Extensions
Type : mkdir intel_back
Type: mv AppleIntelHD* AppleIntelF* intel_back/
Type: touch ../ExtensionsReboot -v

but I get the message "Device is write locked"


I restored the image to a 500GB hard Drive using Transmac and I'm booting from it
that lets me pass through "Waiting for root device" but then i get the bluetooth error

From what I understand is that I have to remove all AppleIntelHD* And AppleIntelF* kexts. I browsed through the files Using Mountain Lion in VM Ware but in the yosemite-zone DMG there are no such Kexts  what to do next?
I appreciate the help

Glad its not just me having this problem... (see about 4 posts below yours)

 

Its a graphics problem is everything that I have read.

 

However as I understand it you should be able to run with your integrated graphics.

 

I'll go over everything I tried, although I'm still stuck, see if it helps you.

 

First up I assume you have followed the guide here?  Which says you have to boot with the /Amd kernal flags?

 

If so (and I'm guessing you have, as I dont think you would be as far as you are) try the following boot flags.

 

-v -f -x

Graphics Enabler=No IGPEnabler=Yes

nv_disable=1

dart=0

 

And thats about as much as I can help. The kexts are missing I assume because of the heavily modified Niresh install, and because they cause problems like this for some users. I assumed my problem was because I have no IG, just a gtx980 which you have to modify kexts to work with anyway. But seeing you have the same problem makes me wonder!
