Try cleaning the 510 connector, pin and threads with a q-tip and rubbing alcohol. DAMP not wet. You might need to use 3 or 4 q-tips. Do the same to the threads and pin on your atty, but you can use a regular old rag for that bit.
Sounds like the chip went bad for some reason. Usually, it is due to a lot of heat. Or dirty 510 pin, which is easy to fix if that is all it is... or if the mod was dropped.. it could mess up the IC chips.
So basically, if it isnt the 510 pin and dirt, you are probably looking at a new mod. Hopefully, they will start some repair shops for those things soon, but as of now.... you and I both have an expensive paper weight. lol.
