Yes it is possible,
First you will have to downgrade to any version before VALL4, you can do this by flashing the stock firmwares via pc odin.

Firmwares can be found in development forums, look for teeshx or MrRobinsons thread.

Once you are on an older firmware then follow instructions from this post to unlock your phone.
