can anyone help me unlocking cid 53? I'm using k810i and i just flashed my phone wid custom acoustic and camera driver, unfortunately the effect wasn't satisfying after all. so i thought upgrading wid seus would revert everything just as before. i did that i wa found that i was wrong! the picture taken still dark wid flash enabled and the sound still too loud as though my speaker gonna burst! and i try to reflash them wid my original acoustic adn camera drive wid xs++ it says my phone wasnt supported! and not only that, i cant navigate my file in my phone using pc! can anyone help me?thanks
