I was trying to access the Recovery Mode on my MacBook Pro5,3 with OSX El Capitan 10.11.6, however every attempt ended in Kernel Panic (KP).
I would see the Apple logo with a loading bar and the following console-like text as an overlay:
panic(cpu 0 caller 0xffffff8013b9654e): "Process 1 exec of /sbin/launchd failed, errno 5"@/Library/Caches/com.apple.xbs/Sources/xnu/xnu-3248.60.10/bsd/kern/kern_exec.c:4584

What I have tried
- Rebooting with CMD+R – results in KP
- Rebooting with Option+CMD+R – results in KP
- Rebooting with Shift+Option+CMD+R – results in KP
- Rebooting with Option and then selection the Recovery partition – results in KP
- I found that the
BaseSystem.dmg
on the Recovery HD partition was corrupted, so I replaced it (together with theBaseSystem.chunklist
file) with a fresh version from the El Capitan installer. To no avail, I got a KP again, albeit a slightly different one:
panic(cpu 0 caller 0xffffff8003c3995e): "A kext releasing a(n) BroadcomBluetoothHostControllerUSBTransport has corrupted the registry."@/Library/Caches/com.apple.xbs/Sources/xnu/xnu-3248.60.10/libkern/c++/OSObject.cpp:200
What else can I try?
My final goal is to boot to Recovery, disable csrutil
, patch a system file such that my headphones don't launch iTunes automatically, then enable csrutil
again.
Notes
Booting to Safe Mode by holding Shift during startup does work as expected.

After I forgot this issue for a while I stumbled upon a very useful tool made by Chris Silvertooth. The latest version of his Recovery Partition Creator can be found on his download page.
Using the application is very simple, I have successfully recreated my recovery partition on El Capitan (OS X 10.11.6):
