You won't get any AP for flipping a portal, even though all the links and fields get destroyed.

The portal, as it was, will only change it's owner to either **you** (if it was an enemy portal) or to `__ADA__` or `__Jarvis__`, depending on what your and the portal's faction is.
  
This is the result of using the Jarvis virus by a resistance agent on a resistance portal.

 - Flipping a portal means that **ALL** resonators and mods will **change** the owner, they won't be destroyed.  

 - The Capture date will change to the day the portal was flipped and the day counter will reset.

 - The maximum of 1xL8,L7,.. resonators or 2 mods per agent don't apply for the flipping and also if you are level 5, you can flip a portal with L8 resonator.  
**!!** However, if the limits are exceeded you **won't** be able to deploy **ANY** additional resonators.

 - The cost to flip a portal is 1000 XM per portal's level.

 - Using the Jarvis or ADA by the same faction agent is useful if you want to get rid of blocking links.  
*note that you can't use the Jarvis virus on a green portal and ADA on a resistance portal in order to do so.

 - There is 1 hour cooldown, where the portal won't get flipped after using a Virus, but you will still **lose** your Virus if you try to do so! Also the portal will not tell you if it is protected or not.
