I am stuck during the boot process, at first before entering the passphrase for `/data` and now at the SIM PIN screen. At this point, adb is inaccessible (normally adbd would start up after unlocking `/data`, etc.).

How can I start `adbd` during boot? This is a CM 10.2 userdebug build for i9300 with `/default.prop` (from initrd) containing:

```
ro.adb.secure=1
ro.secure=1
ro.allow.mock.location=0
ro.debuggable=1
persist.sys.usb.config=mtp,adb

```

I have also tried the following to no avail:

* Edit `/init.rc`, comment out the `disabled` line for `service adbd`.
* Edit `/init.smdk4x12.usb.rc`, add `start adbd` to the `property:sys.usb.config=mtp` trigger.
* Add `persist.sys.usb.config=adb` to `/default.prop`
