 You should figure out which ramdisk is needed for Ubuntu Touch. And make changes in stock ramdisk for this.

 ThanksAs i said earlier you got a dead boot.img due to inline kernel building. 
 So you should do all stuff manually.
 And read this:

 @tank0412 I modify the defconf file and build the kernel and also my twrp recovery build works without any problem so the problem is in the ramdisk of the boot.img. i dont know where the problem is!!!!!
