Root method from the first post do not work
Actually it renders phone unusable (freezing, restarting etc)
Is 360 the only one method that works with thisphone?
After applying this method on second computer, my touch stops responding
Phone turns on but I'm on lock screen (cannot unlock due to touch not working)
Any idea how to restore original firmware to this phone?
To restore touch function, you have to replace corrupted boot.img using ADB (my software version is B11, i used boot.img from B17)
If you want to root, it's better to use english CWM (which includes root) than using methods posted on XDA
