I have a tab2 (P3113) with the same issue. I know this thread is about the note but it is the same basic stuff.
The charger I have will charge my other tab2 but not this one. After trying everything listed in this thread I disassembled it and took a close look at the charging port. Two of the pins were bent and pressed against the back wall. Unfortunately bending them back was not an option as they would not lay flat enough to prevent the charging plug from impacting them again. I removed them through the back of the port in hopes they were not necessary as they did not appear to be connected to any trace on the board.
I still have the problem and suspect it is because one or both of those pins is part of the charging process. Ordered a new motherboard and should arrive in a few days. I will report back if it works.
