Please help to unbrick topic

Hi,

I am looking for some help as I did something stupid...

I came across some posting that explained that the moto has an unused partition under /cache that could be used for the dalvik-cache.

So I tried to move the dalvik-cache there and link /data/dalvik-cache to this new location.

Now the problem is that I get an "unfortunately the location-service has stopped" message all the time that makes the device unusuable (as soon as I press ok the same warning appears again).

When I try to boot into recovery I get a "dead android robot".

I can however access the device via adb, unfortunately I am not able to get a root shell. My device is rooted, but su in an adb-shell just hangs.

If I could only get a root-shell I could undo my changes and hopefully my device will work again, but I have to idea on what to try...

Can anone help me here?
