My friend, how could a ROM kill a phone ?You can't believe how pissed of I am right now. I literally want to cry.
It's not impossible, but too many users - including me - have already installed that ROM without problems.
If your phone died it's probably a hardware problem and it has to be a coincidence or else we are all in danger!
Most of our Note II phones are very old devices, I bought mine on the first week of November 2012.
Leave the battery out for a few minutes and try again.
