Dont flash it on a wrong phone! your risk to brick it!

Never needlessly Download preloader and DSP_BL blocks! It is always dangerous! On some models of phones you will have a brick even if you download these blocks read from phone which you own! Always remove from them marks in SPFT! ALWAYS have a working backup of your original ROM before you flash a new unknown ROM.
