restart phone (take out battery and put it back after then power up with holding volume button down) and hold volume down you will get color boot screen
after then connect phone trough usb cable to PC wait to detect it (under color boot screen shows USB)
run RUU and Perform Task 28 flash your ROM (RUU_Signend_0409.nbh)

Task 29 clears only internal storage of the phone (it is like formating storage) !
everytime you will make Task 29 after then you must make Task 28 (flash the rom to phones internal storage)
