Could you explain how you tried to set the vibrator strength?
Also be sure to checkout /proc/last_kmsg if you face reboots.

I tried to edit it using Root Explorer (the app I purchased long time ago). It does not allow to change permissions and any change of „18” is not saved.
Never heard of last_kmsg? Where is the issue? What should I see and do in this case? Also, a friend of mine has the same problem with the reboots on his XT1033 with the last kernel. I use a XT1032.
