is your phone debranded? if yes, then any firmware would do. but make sure to install the right custom pack. if you are using S_ASIA_LEVAN, then find the custom pack for S_ASIA_LEVAN.
flash the fs using xs++. then enter the fs of the phone using far manager. copy all the files in the custom pack to "tpa/preset/custom"
then quit far. open xs++ once again and flash back the main. you're done.
for a detailed tutorial, search the forum. you'll find one posted by "TanZeeL".
ALL THE BEST
