few days back i flashed 2 drivers into my k810i: custom acoustic and camera drivers. sadly it didnt worked out as what i've expected. so i wanna revert back to it's original state. didnt pretty much realized that, never ever update with seus, bcos i'm just a newbie around. so is there anyway around that can rever back my phone to original state aside from flashing it with original driver?many thanks for thoe who can spend some time look into my matters and solve it, thanks again
