Switch Dalvik/ART via ADB, super easy.

From Dalvik to ART and back again, a story of ADB.

Connect phone.

adb pull /data/property/persist.sys.dalvik.vm.lib

Open the file in notepad or whatever.

Replace the text libart.so with libdvm.so and you've got Dalvik.
Replace the libdvm.so ... yeah, you get it, vice versa.

adb push persist.sys.dalvik.vm.lib /data/property/

Boom! ... well, hopefully not. ;)
