Hey all and happy new year to all xda members
my friend has S3 i9300 and he bricked his phone while rooting... he select the note 2 cf-root file instead of i9300 by accident and now...after he flashed the stock firmware, phone worked but touch screen not responded ... so will the full stock (4 files) help or he should play the touch screen module ..... any solution ??!
