Enabled De-Bugging Mode, but phone will not switch on

[AC Question]

I have enabled debugging mode on Samsung Note 2, but when I connect to my PC, it says debugging needs to be disabled. The problem I have is the phone will no longer power on since I enabled debugging mode.

I just want to disable debugging mode but phone will NOT power on atall. I have tried a number of button sequences, but NONE work.

Can someone please advise if I will be able to use this phone again???
