Touch IC Reballed 2 times, cumulus overheating

Hello, as the title says, i reballed the ic (meson) two times: the first time the device worked for a while, and after the first shutdown, suddenly it stopped working (no image, not detected by itunes). I noticed immediately that cumulus ic was getting very hot on phone boot. So I reballed the touch ic for the 2nd time hoping that there was something wrong with its balls (a bridge). Unfortunately, the result is the same : cumulus is getting very hot and there’s no image at all, should I try to reball it? Maybe I applied too much heat on it and I created a bridge between its balls.

Thank you :)
